MTVR Operating the MK-Series Vehicle Under Unusual Conditions (Remote)
Container Cargo 10 and 20-ft Containers/Shelters: Introduction
The 10- and 20-ft shelter/container is a multiple-use configuration. Some are containers for transporting materials; others provide tactical EMI/EMC shelters for various operational, logistical, or medical functions. The standard shelter/container is 8 ft tall and the same width as the truck (8 ft). The MK23/25 can transport one 10-ft container or EMI/EMC shelter/container. The MK27/28 can transport one or two 10-ft shelter/containers or one 20-ft shelter/container. Shelter/container weights range from 2,950 lbs to 15 tons. Be sure to verify that the weight of your cargo is within the capability of your vehicle based on the cargo type and terrain. Refer to the Operator's Manual for specific weight limits for your situation.
Container Cargo 10-ft Shelter/Container: MK23/25 Placement
The 10-ft container is secured to the cargo bed using ISO locks 1 and 4. The MK23/25 cargo bed is 14 ft long, therefore a 20-ft shelter/container cannot be carried.
Loading and Unloading Personnel Armor Troop Carrier Introduction
The Armor Troop Carrier is configured with armor protection. This limits the vehicle to transporting up to 12 personnel. Loading and unloading personnel differs in the troop carrier since it has built-in troop seats and an affixed ladder.
Loading and Unloading Personnel Cab Preparation
The MK-series vehicle can carry two passengers in the cab unless the gunner stand is in use. You are required to have an assistant operator in the cab with you at all times. As the operator, you need to make certain that personnel riding in the cab: Stow their gear in the cargo bed Properly fasten their seatbelts Comply with all safety precautions and procedures
Container Cargo Quad-Con: MK23/25 Placement
The MK23 and MK25 are capable of carrying two quad-con containers with a total combination weight of 7.1 tons off-road and 10 tons on-road. When carrying two quad-con units: The units must be coupled together after loading. Secure the load using ISO locks 1 and 4. On road, the heavier unit should be placed in the forward position. Off-road, the containers must be equally loaded.
Container Cargo Six-Con: MK23/25 Placement
The MK23/25 can carry one or two six-con containers. One six-con If you are carrying one six-con container: Place the container in the forward position, nearest the cab. Secure the container using ISO locks 1 and 2. Two six-cons If you are transporting two six-cons, the heavier container must be placed in the forward position. For example, if one unit contains a fully loaded water tank and the other unit contains a water pump, the following guidelines apply: The water tank should be placed closest to the cab. Use ISO locks 1 and 2 to secure the water tank. The water pump should be placed at the rear of the cargo bed and secured using ISO locks 3 and 5.
Container Cargo 10 ft and 20-ft Shelter/Containers: MK27/28 Placement
The MK27/28 can carry up to two 10-ft shelter/containers or one 20-ft shelter container. Prior to loading a shelter/container, adjust the interior materials/components so that the center of gravity is close to the center of the shelter/container. Container placement is as follows: One 10-ft shelter/container Secure the shelter/container using ISO locks 1 and 4. Two 10-ft shelters/containers Secure the first 10-ft container using ISO locks 1 and 4 Secure the second container using ISO locks 5 and 8. When loading two containers, the heavier container must be placed at the front of the cargo bed. One 20-ft shelter/container Secure the shelter/container using ISO locks 1 and 8.
Vehicle Configuration Introduction
The MTVR can be configured to transport troops in the cargo bed using equipment normally stowed on the vehicle. To configure the cargo bed for troops, unstow and install the following equipment: Dropsides Tailgate and ladder Troop seats A cargo cover may also be installed over the troop area.
Container Cargo ISO Lock Locations
The MTVR cargo bed is designed with ISO locks at specific locations to fit the six-con, quad-con, and 10/20-ft shelter/containers. ISO lock locations: The MK23 and MK25 have five standard ISO locks on each side of the cargo bed. The MK27 and MK28, with a longer cargo bed, have three additional locks for a total of eight on each side of the bed. The locks at positions 2, 3 and 6 are "shallow" locks; the others are standard locks NOTE: Some of the ISO locks on the MK27/28 are "shallow" locks. These locks are similar to the standard lock in the method by which they secure the container to the cargo bed. However, you must use a separate ISO lock spanner wrench to loosen, align, and tighten the lock. Refer to the operator's manual for the operating procedure.
Container Cargo Six-Con: Container Weights
The Operator's Manual provides the weight ranges for the six-con tanks and pumps: Water tank ....... 2,530 to 9,730 lbs Fuel tank ....... 2,530 to 8,830 lbs Water pump ....... 3,000 lbs Fuel pump ....... 4,000 lbs The combined weight of the six-con units may not exceed 10 tons (MK23/25) or 15 tons (MK27/28) on-road. The weight maximum off-road is 7.1 tons. For vehicles with armor, the maximum payload is reduced. Refer to the operator's manual for specific limits. The placement of six-con containers depends on how many containers are being loaded onto the cargo bed, the type of container (tank or pump), and how much water or fuel is being carried in the tank.
Vehicle Configuration Install the Front Dropsides
The front dropsides must be installed before the rear dropsides. Follow these steps to install the front dropsides. 1) locate the hinge pins and barrels 2) Slide hinge barrels onto hinge pins 3) Rotate the dropside into position 4) Lock the dropside in place 5) Install the remaining front dropside.
Container Cargo Six-Con: Introduction
The six-con is a shipping frame for transporting bulk liquids (water or fuel) and dispensing equipment (pumps). There are four types of six-con units: Water tank Water pump Fuel tank Fuel pump One six-con unit is the same depth as the cargo bed (8 ft), approximately 6½ ft wide and 4 ft high. The MK23/25 is capable of carrying one or two six-cons. The MK27/28 can carry up to three six cons
Vehicle Configuration Tailgate
The tailgate is stowed on the headboard when not in use. When configuring the vehicle for personnel, remove the tailgate from the headboard before installing the front dropsides. Two personnel are required to unstow the tailgate.
Vehicle Configuration Troop Seats and Backrests
The troop seats and backrests are installed after the dropsides and tailgate have been installed. Installing the troop seats involves first installing the backrests, then installing the seats themselves. During the installation of the backrests, the staves that support the cargo cover must also be installed to hold the backrests in place. You will usually install the cargo cover once the troop seats and backrests are in place.
Rules for Loading Cargo Never Overload the Vehicle
The weight limit that applies to your cargo load is based on several factors: Type of cargo - palletized or ISO container type Vehicle model - long or short bed and armored or not armored Terrain - on or off-road The general weight limits/capabilities for the type of cargo are: Palletized (non-ISO) cargo ISO (container) cargo Always refer to your Operator's Manual to determine proper weight limit.
Effect of Cargo on Vehicle Handling Acceleration
The weight of a vehicle affects the vehicle's rate of acceleration. Even an empty MTVR, because it weighs far more than a passenger vehicle, takes longer to build up speed. Acceleration is further reduced with the additional weight of cargo. You should also be aware that cargo has a tendency to shift toward the rear of the vehicle during acceleration.
Rules for Loading Cargo Determining Weight
The weight of your cargo is a primary factor in determining whether your vehicle is loaded properly. Most pieces of military equipment have a data plate listing the weight of an item. If it does not, then the weight is usually stenciled on the item or container. If the cargo weight is not listed, the load should be taken to a scale and weighed. If a scale is not available, then it is up to you to estimate the weight. In making your decisions, follow the rule: It is safer to under load rather than overload your vehicle.
Vehicle Configuration Dropsides
There are four dropside sections, two for each side of the vehicle. When not in use, they are stowed in a stowage compartment under the cargo bed. The stowage compartment is accessed through a small door at the rear of the vehicle. Dropsides are installed in sequence. The front dropsides must be installed first, then the rear dropsides. Prior to installing the dropsides, make sure that all top tie-down rings and ISO locks are recessed in the cargo bed.
Driving In Icy and Snowy Conditions Removal of Snow and Ice
There are specific steps you need to take when preparing to drive in extreme cold and in snowy conditions. Before you start your vehicle, remove all snow and ice. If allowed to accumulate, you risk damage to the equipment. Snow and ice can slow or even stop movement of many crucial parts. If your vehicle is equipped with an engine arctic heater or an arctic cargo kit, check the equipment for proper operation before you start out. Refer to the operating procedures, warnings, and cautions in the operator's manual to ensure safe operation.
Driving in Icy and Snowy Conditions Driving With Tire Chains
Tire chains are installed to improve wheel traction. Do not use tire chains on hard surfaces when there is no wheel slippage. When using chains you should stop and inspect tire chains every hour of operation and tighten as required. Specific precautions should be taken when driving with tire chains: Set the CTIS to CC or HWY Maintain the CTIS setting Monitor vehicle speed
Loading and Unloading Personnel Cab Entry and Exit
To safely enter or exit the cab, maintain three points of contact with the vehicle. For example, use grab handles on the door and side of the truck when moving your foot from step to step. And have both feet on steps when you reposition your hand grip. The safest way to enter and exit the cab is to climb in or out as you would climb up or down a ladder.
Driving Safety Railroad Crossing
To safely transport passengers over railroad crossings, follow these steps. 1) Slowly apply brakces. 2) Stop 15-5- feet from crossing 3) Look and listen 4) Slowly accelerate
Driving Safety Winding Roads
To safely transport passengers over winding roads, you need to follow these safety guidelines: Slow down when approaching a curve: You should slow down when approaching a curve. Approaching a curve at high speed can cause your passengers to be thrown around, resulting in injuries. Begin slowing before entering the curve. Take the curve at a slower speed than the posted speed limit. Brake smoothly: You should brake smoothly and avoid slamming on the MTVR's brakes. Applying the brakes suddenly at a high rate of speed can cause injury to yourself and passengers. Your passengers can be thrown forward, against each other, and against the headboard. Steer the vehicle smoothly through the curves: Steer the vehicle smoothly through the curves. Turning or jerking the steering wheel sharply when approaching or driving through a curve can cause your passengers to lurch from side to side, potentially injuring them
Weight Limits for ISO (container) Cargo
Unarmored MK23/25 and MK27/28 - 10 tons (MK23/25) on primary and secondary roads -15 tons (MK27/28) on primary and secondary reads -7.1 tons off-road Armored MK23/25 and MK27/28 6 tons (MK23/25) on primary and secondary roads -12.2 tons (MK27/28) on primary and secondary roads 6 tons - off-road
Palletized (non-ISO) cargo
Unarmored mk/23 or mk27/28 -15 tons - primary and secondary roads -7.1 tons - off road armored mk23/25 or mk27/28 -12.2 tons - primary and secondary reads -6tons - off-road
Driving In Icy and Snowy Conditions Driving On Snow
Use extreme caution when driving on snow. Sliding while turning or stopping can be common in this type of weather. When driving on snow: Accelerate slowly. Rapid acceleration can cause your wheels to lose traction. Slow down gradually. Hard braking can cause your vehicle to skid. The MTVR is equipped with anti-lock brakes and an all-wheel drive system to help you handle poor traction conditions. If you do begin to skid, turn the wheels in the direction of the skid.
Container Cargo Six-Con: MK27/28 Placement
Use the following guidelines when loading six-con containers on the MK27/MK28: One six-con Two six-cons Three six-cons
which of the follwing factors affect the Maximum weight you are authorized to carry on assignment mission?

Container Cargo MK27/28 Placement of Quad-Con Containers
When carrying quad-cons, the individual containers must be coupled together in pairs after loading. The MK27/28 can carry two or four quad-con units. Container placement is as follows: Two quad-cons: The front end of the quad-con pair cannot be secured with ISO locks and must be tied down. When loading two quad-cons: Secure the rear container with ISO lock 7. Connect the two quad-cons together. Secure the front quad-con with two chain or cable tiedowns. Four quad-cons When loading four quad-cons, load the heavier container pair in the forward position. Secure the forward pair of quad-cons with ISO locks 1 and 4. Secure the second pair of quad-cons using ISO locks 5 and 8. After loading, couple the containers together in pairs.
Driving In Icy and Snowy Conditions Driving On Ice
When driving in cold or icy weather, you may encounter unexpected patches of ice. Driving on ice is one of the most dangerous driving situations you will encounter because traction on an icy surface is almost non-existent. Black ice refers to a thin, transparent layer of ice that forms on a cold road surface as a result of misting rain or freezing of a wet road surface. It is almost impossible to see. The road appears clear, but in fact has a layer of ice on top. When driving in such weather conditions: Use extreme caution Proceed slowly
Guidelines for Operating on a Grade Maintain a Safe Speed
When driving on hills, the posted speed limit is not necessarily a safe speed for your MTVR. Consider the following factors in determining the speed you should drive when operating on a grade: Steepness of grade The steeper the downhill grade, the more your speed will tend to increase. Keep your speed under control by using a combination of service brakes, engine brake, and transmission gear range 1)Length of the grade The length of the grade has a big impact on the potential speed of the vehicle. Plan to keep your speed down to avoid over-using your brakes on long downgrades. Using your brakes both uses air supply and builds up heat. If a lane is designated for slow moving vehicles, use that lane. A long, steep hill requires more speed control than a short distance. 2)Weight of vehicle and cargo The greater the weight of the vehicle and cargo, the harder it can be to hold down your speed when traveling downhill. Heavier loads require additional reduction in speed and lower transmission gear range to maintain vehicle control 3) Highway warning signs On highways, you will usually see warning signs to alert you as you approach a steep downgrade. Use this information to select a lower transmission gear range and prepare to apply your engine brake to help you control your speed 4) Weather Rain, snow, or ice can cause slippery conditions that make driving hazardous. Drive carefully and slowly when going downhill in inclement weather. 5) Road condition The MTVR is designed for off-road, as well as highway travel. While traveling cross-country, you may encounter different road conditions such as unpaved surfaces, extreme grades, and poor traction conditions. Transmission and CTIS selections will often require additional limits on your speed 3)
Set the CTIS to CC or HWY
When driving with tire chains, the CTIS setting must be CC or HWY, as appropriate for the travel surface. The CTIS must not be set below Cross-Country (CC). When the tires deflate to MSS or EMER CTIS settings, the tire chains no longer fit properly and will cause serious tire damage.
Vehicle Configuration Ladder
When not installed on the tailgate, the ladder is placed in a side mount near the front of the cargo bed. To prepare for transporting troops, the ladder is removed from the side mount and installed on the inside of the tailgate
Types of Cargo
When operating an MTVR, you are responsible for safe transport of allowed cargo on your vehicle. Allowed cargo is defined as anything that is authorized for transport. As an operator, you may be authorized to transport several types of cargo including: Palletized cargo Cargo containers Hazardous materials
Guidelines for Operating on a Grade Introduction
When operating in mountainous or hilly terrain, gravity has a greater affect on the way your vehicle handles than it does on smaller vehicles: On steep downgrades, gravity can cause a greater increase in the speed of your vehicle. On an upgrade, gravity can significantly slow you down.
Guidelines for Operating on a Grade Safety Considerations
When operating in mountainous or hilly terrain: Watch for posted warning signs that indicate the length and steepness of a grade. Obey the posted speed limit. Select an appropriate gear to control your speed. Keep a constant eye on your instrument panel and the traffic around you. Use proper braking techniques. When possible, plan ahead. Obtain information about any long, steep grades along your planned route.
Driving In Icy and Snowy Conditions Slowing Down On Snow
When slowing or stopping the vehicle in snowy conditions, follow these guidelines: Apply steady pressure to the service brakes to maintain control of the vehicle. Avoid using the engine brake. Maintain a firm grip on the steering wheel to keep the vehicle on course. Apply the service brakes earlier than usual to allow for additional stopping distance. WARNING Use the engine brake/retarder only when the vehicle tires have good traction. Use of the engine brake on slick surfaces can cause the vehicle to skid and can cause injury or death to personnel.
Palletized Cargo Handling Drums
Whenever you are carrying drums, such as 55-gallon drums, you need to be aware of special handling considerations. Drums or barrels can be many different sizes, including 10 and 55 gallons, which makes them irregularly-shaped cargo. They also have some unique loading requirements. Since drums and barrels roll easily, there are two loading methods used to avoid unwanted shifting or leaking during transport: horizontal (side-loading) and upright.
Driving Safety Introduction
While operating an MTVR, the safety of your fellow Marines is a high priority. Be especially aware of traffic at intersections, railroad crossings, and bridges. Being constantly aware of your surroundings will help you avoid sudden stops and give time to slow the vehicle safely. Applying your brakes abruptly or turning too sharply has potential to cause injury for those personnel riding in the cargo area.
Driving in Icy and Snowy Conditions Driving Without Tire Chains
You are driving on an unpaved road covered with snow. The driveline and transmission are now warmed up. For the best traction in slippery conditions when driving without tire chains, the CTIS should be set to the Mud/Sand/Snow (MSS) setting. Top speed for this setting is 15 MPH. The transmission gear selected should be the first (1) or second (2) gear to provide the best control on slick and icy roads. Keep in mind, the gear you select may be affected by the vehicle's load and the CTIS load setting.
Rules for Loading Cargo Never Transport Personnel and Cargo Together
You are never permitted to transport both cargo and personnel in the cargo bed at the same time. The purpose of this restriction is to prevent serious injury to personnel if the cargo shifts during transport.
Ascending a Grade Choose the Appropriate CTIS Setting
You may experience wheel slippage on steep grades, particularly when operating off-road or on non-paved surfaces. You should select the appropriate CTIS setting for your driving situation: Slight grades <10% When on primary and secondary roads, you commonly encounter slight grades up to 10 percent. Maintain the CTIS HWY setting. Off-road, select CC or MSS as appropriate for terrain conditions Moderate grades 10% to 25% Moderate grades between 10 and 25 percent are sometimes encountered when traveling cross-country or on unpaved roads in mountainous terrain. Select the CTIS CC terrain setting to reduce tire pressure and provide improved traction. Use MSS when required by the terrain conditions Extreme grades >25% For extreme grades over 25 percent, the initial CTIS selection should be CC. If wheels start to slip, stop the vehicle and change the CTIS setting to MSS. If wheels continue to slip, stop and change the terrain setting to EMER. On extreme grades, use a combination of CTIS setting, transmission gear range, and driveline lock configuration to control the vehicle
Rules for Loading Cargo Be Aware of Cargo Height
You should always be aware of the height of the loaded cargo. It is important to keep the height of the payload low. A load that is stacked too high raises the vehicle's center of gravity, reducing safe speed when maneuvering and increases the risk of a rollover. A tall load can make the vehicle harder to steer and increase the risk of load shifts or loss of control. Exceeding height limits creates a risk of losing the load when driving under a bridge or overpass.
Container Cargo Unlocking ISO Locks
1) Loosen the ISO lock unit 2) Turn the handle 1/4 turn. 3) Unload the ISO continer 4) Lower the ISO lock and tighten the nut. CAUTION To prevent the nut from turning when the pin is released, ensure the locking pin rests in a notch of the nut. Failure to comply may result in damage to equipment
Container Cargo Locking ISO Locks
1) Raise the lock 2) Move the lock into the load position 3) Load the container 4) Lock the ISO lock WARNING After tightening the ISO lock nut, ensure the locking pin rests in notch of nut to prevent the nut from turning. Failure to comply could result in damage to equipment.

Palletized Cargo Distributed Pallet
A distributed pallet is a wood, metal, or plastic composite pallet that can hold various types of cargo. Examples of items that might be palletized are: Sacks Cartons of parts MREs Other types of authorized cargo When transporting palletized cargo, the MTVR can carry up to the full cargo capacity: 15 tons on primary and secondary roads, and 7.1 tons off-road. This capacity is reduced for armored vehicles to 12.2 tons on-road and 6 tons off-road.
Ascending a Grade Driving Uphill
A rule of thumb when driving uphill is: The steeper the grade, the longer the grade, and the heavier the load, the more you will have to use the vehicle's lower gears to climb a hill. You should select an appropriate gear range based on your vehicle's weight and the steepness and length of the hill. The MTVR will maintain proper transmission selection based on vehicle speed and engine rpm. As your speed decreases, the transmission will automatically downshift to maintain engine power. The engine has maximum horsepower at 1800 rpm. Through experience, you will learn the best transmission gear range to select to maintain maximum power for an uphill climb
Vehicle Configuration Armored Vehicle
AMK variants may be configured with both cab and troop carrier armor. The Armor Troop Carrier, sometimes referred to as the "armadillo," includes: 3/4-height sides that provide armor protection for troops Built-in seating along the centerline with seats facing outward A hinged ladder in the rear for access Fixed frames and overhead bows to support a canvas cover
Palletized Cargo Tiedowns
Acceptable tiedowns include: Ropes Straps Chains with chain binders A chain binder is used to tighten the chain across the load. Blocks and braces are also used to add stability to the cargo. Blocks and braces prevent cargo from moving around on the cargo bed and causing damage to other cargo or the vehicle
Vehicle Configuration Install the Rear Dropsides
After installing the front dropsides, install the rear dropsides and attach them to the front dropsides. Follow these steps to install the rear dropsides. 1) slide the hinge barrels onto the hinge pins 2) Rotate the dropside into positon 3) Lock the dropside in place 4) install the remaining rear dropside. 5) install the locking rod.
ENGINE HIGH IDLE
After starting the engine, run the engine until it idles smoothly, then engage the ENGINE HIGH IDLE switch to increase the engine speed to 1500 rpm. You may engage the ENGINE HIGH IDLE switch for up to 25 minutes.
Loading and Unloading Personnel Introduction
After the MK-series vehicle is properly configured to transport personnel, you are now ready to load personnel in the vehicle. As an operator, you are responsible for making sure troops enter and exit the vehicle safely. This section covers how to safely enter and exit the: Cab Cargo bed Armor Troop Carrier
Monitor vehicle speed
Always monitor your vehicle's speed when driving with tire chains. The maximum speed when using tire chains is: 10 MPH on highway 15 MPH off road
Palletized Cargo Weight Distribution
An important factor that affects cargo placement is the weight bearing capacity of the axles. Weight should be placed so that the payload center of gravity is approximately centered over the cargo area. The heaviest load should be placed over, or in front of, the intermediate axle. The rear axle should carry the lighter load. Proper placement provides sufficient weight distribution to the front axle. A load that is too far to the rear of the cargo bed can cause a loss of steering control.
Rules for Loading Cargo Verify Cargo is Properly Secured
As your cargo is loaded, verify that the load is properly placed. Verify that tiedowns are properly positioned and securely fastened on non-ISO cargo. For containers, verify that all applicable ISO locks are correctly tightened and locking pins in place. As you travel, use each stop or rest point as an opportunity to check that your cargo remains properly secured and has not shifted. You may need to re-tighten tiedown straps, ISO locks, or chain binders.
TRANSPORTING PERSONNEL
At the end of this lesson, you will be able to: Select the actions required to configure the MTVR for transporting personnel. Select the safe actions for loading and unloading personnel. Identify the safety guidelines for transporting personnel. Identify the driving considerations that apply to the safe transport of personnel. It will take you approximately 40 minutes to complete this lesson.
Loading and Unloading Personnel Entering the Cargo Bed
Before loading or unloading personnel, the tailgate must be lowered. Do not allow troops to climb over a raised tailgate. In order to safely enter the cargo bed, personnel should climb into the back of the vehicle one at a time and follow these guidelines: Place any gear, including a rifle, into the cargo bed area first. Maintain three points of contact with the vehicle. Use top of the tailgate and top rung of the ladder to climb into the vehicle since there are no handles to grab. Use the ladder and the tailgate for balance and leverage.
Loading and Unloading Personnel Cargo Bed Introduction
Before loading personnel into the cargo bed, you must ensure that your vehicle can safely transport the personnel. When equipped with troop seats, the cargo area passenger capacities are: MK23/25 short bed: up to 16 personnel MK27/28 long bed: up to 20 personnel MK29/30 dump bed: up to 12 personnel with troop seat kit installed AMK23/25 with armor troop carrier: up to 12 personnel AMK23/25 without armor troop carrier: up to 16 personnel
Safety Guidelines Briefing Personnel
Before the trip begins, brief your passengers on safety precautions and emergency procedures: Remain seated at all times. When ready to disembark, do not jump from cargo bed to the ground. Do not extend hands or arms outside the vehicle. Stay alert in case an emergency arises.
How could placing more weight in the rear of the cargo bed than the front affect the steering of the MTVR?
Can cause the steering axle weight to be too light to steer safety
Palletized Cargo Securing Cargo
Cargo must be secured to the cargo bed using cargo tiedowns such as straps or chains and binders. Tiedowns must be strong enough to lift one and one-half times the weight of the cargo being secured. Material placed on pallets should be strapped to the pallet itself prior to loading, then secured to the cargo bed with tiedowns. Use at least two tiedowns per cargo item or pallet.
Effect of Cargo on Vehicle Handling Starts, Stops, and Turns
Carrying a load of cargo affects the way your vehicle handles. The weight and placement of the cargo affects how the vehicle reacts when: Accelerating Handling curves and turns Stopping
Effect of Cargo on Vehicle Handling Curves and Turns
Carrying cargo affects the way that the MTVR handles curves and makes turns. The proper placement of cargo is especially important when handling curves or turns because if the load is not balanced, the vehicle may become difficult to steer. Raising the vehicle's center of gravity too high causes a greater chance of rollover. Shifting weight too far to the rear can cause the front axles to be under-loaded. This can cause the steering axle weight to be too light to steer safely. Overloading and placing too much weight on the steering axle can make the vehicle hard to steer. It can also damage the steering axle and tires.
Operational Impact of Cold Weather Batteries
Cold temperatures can cause batteries to freeze and crack. A cracked battery must be replaced prior to starting the engine. The MTVR is capable of starting with two batteries down to 10°F. Below that temperature, two additional batteries should be installed. If the ambient temperature is expected to be below 32°F, two additional batteries may be installed at the unit's discretion.
Driving In Icy and Snowy Conditions Driving Over Bridges
Decks of bridges cool faster than other road surfaces. This means that moisture often condenses on them and freezes quickly into ice. Slow down before you come to a bridge. This is particularly true at dusk and after dark because the temperature can fall quickly at that time of day.
Operational Impact of Cold Weather Fuel System
Extremely cold temperatures can cause water in the fuel system to freeze, causing a blockage. Remove water by draining the fuel/water separator after each mission and before topping off the fuel tank. Keep the fuel tank as full as possible during cold operations. Water forms in an empty fuel tank as it cools and can freeze.
Vehicle Configuration Unstow the Dropsides
Follow these steps to unstow the dropsides. 1) Remove the stowage door. 2) Remove dropsides from stowage 3) Reinstall the stowage door WARNING Two personnel are required to unstow, install, remove, or restow dropsides. Failure to comply may result in injury to personnel or damage to equipment.
Vehicle Configuration Unstow the Tailgate
Follow these steps to unstow the tailgate from the headboard. 1) Remove the T-bolts 2) Remove the tailgate
Rules for Loading Cargo Introduction
Following basic cargo-loading guidelines will help you avoid problems when transporting cargo. When loading cargo, pay attention to the following rules: Never overload the vehicle. Never transport personnel and cargo together. Be aware of cargo height. Ensure the cargo is properly secured.
Loading and Unloading Personnel Troop Carrier Entry and Exit
For personnel to enter and exit the troop carrier, you must first lower the ladder. To safely enter and exit the troop carrier, personnel should climb into the back of the vehicle one at a time and follow these guidelines: You must maintain three points of contact with the vehicle. The troop carrier is equipped with ladder support straps for climbing up and down the ladder. Use the ladder, support straps, and vehicle for balance and leverage.
Loading and Unloading Personnel Exiting the Cargo Bed
For troops to exit the cargo bed, you must lower the tailgate and detach the troop strap. You should direct personnel to exit the vehicle one at a time using three points of contact. For example: one hand is on the MTVR, the other hand is on the top rung of the ladder while a foot is on the rungs of the ladder climbing backwards. You should also direct personnel to exit the vehicle on the curb or sidewalk side of the street (away from traffic).
Container Cargo Hazardous Materials
Hazardous materials are defined as materials or substances that are capable of posing a risk to health, safety, or property. The following are just a few examples of hazardous materials: Explosives Flammable liquids Flammable solids Oxidizing materials You must have special permits and training before being allowed to transport hazardous cargo. You will also need documentation authorizing transportation of the materials. Keep the authorizing documents with you in the vehicle at all times.
Container Cargo ISO Locks
ISO locks are used to fasten a container to the cargo bed. The ISO locks are recessed in the cargo bed when not in use. Before loading an ISO container, the lock is raised so that the container socket can be aligned properly with the lock. The raised lock guides the foot of the container into position on the cargo bed. When the container has been placed on the cargo bed, the ISO lock is tightened to secure the container to the bed. When unloading the container, the ISO lock is unlocked, the container is removed, and the ISO lock is lowered into the cargo bed recess.
Operational Impact of Cold Weather Driveline
If the transmission oil temperature is below 19°F, the transmission will operate only in: N (Neutral) R (Reverse) 3 (Third gear) If you push D to select a forward gear and the transmission oil temperature is below 19°F, the transmission will automatically go to 3. When the transmission oil temp increases above 19°F, the other gears will be available. Drive slowly for the first 3 to 5 miles to allow the driveline and tires to warm up. Take corners slowly to avoid damaging the driveline.
Container Cargo Six-Con: Dispensing Water or Fuel
If you are transporting two liquid-filled containers, you should empty the liquid from the rear container first and then empty the forward container when the rear container is empty or near empty. When you fill two six-con containers with liquid, you should fill the container at the front of the cargo bed first and then fill the liquid in the container at the rear of the cargo bed. Because of the weight of liquids, the situation to avoid when emptying and re-filling containers loaded on the MTVR is having a full container at the rear and an empty container at the front of the cargo bed.
Palletized Cargo Delivery Destination
If you must carry cargo to more than one destination, consider loading your cargo in the opposite order in which it will be unloaded. Load the cargo for the last destination near the front of the cargo bed. Load cargo for later destinations further back. This can reduce the need to reposition cargo during your mission. Be mindful of weight distribution requirements. Do not unbalance your cargo load in an attempt to make it easier to off-load at different locations.
Effect of Cargo on Vehicle Handling Cargo Shifting
Inspect your cargo after loading and at each stop or rest point to verify it remains properly secured. If necessary, tighten tiedowns or ISO locks. Cargo that is not properly secured can shift, making your vehicle difficult to maneuver and creating a hazard for both you and other drivers. Use the side mount ladder if you need to climb onto the cargo bed to check security of your cargo.
Vehicle Configuration Unstow the Seat Components
Like the dropsides, the backrests and troop seats are stowed in the stowage compartment under the cargo bed. You usually remove the backrests and troop seats from stowage when you remove the dropsides. You also need to unstow the bows and staves from the headboard. The bows are located on the cargo bed's headboard. The staves are in slots in the headboard.
Effect of Cargo on Vehicle Handling Liquid Loads
Liquid loads can be potentially dangerous to transport. As the vehicle moves, the liquid shifts from side to side within its container. This causes a shift in the center of gravity. This is especially dangerous when the vehicle changes direction or climbs up a slope. The shifting weight can cause a loss of steering control as you try to compensate for the effects on your vehicle.
Palletized Cargo Uniform and Non-Uniform Cargo
Load items of uniform size and weight together, whenever possible. This simplifies blocking, bracing, and distributing cargo. Different sizes, shapes, and weight of cargo can also affect how your vehicle is loaded. Sometimes your cargo area will only be partially filled when you reach maximum cargo weight. Other times, you will fill your cargo bed without coming close to your maximum weight limit. Consider differences in the following types of cargo: Dense items Bulky items Irregularly-shaped items
Container Cargo Introduction
MTVRs are configured to carry three basic sizes of ISO-compatible containers: six-con, quad-con, and 10-ft shelter/container. Additionally, the MK27/28 can carry a 20-ft shelter/container. The ISO container is designed for rapid loading and unloading. The containers are secured to the bed of the truck using permanently-installed ISO locks. This eliminates the need to secure the load with straps, chains, or binders when preparing for transport. Prior to loading any ISO container, the dropsides, troop seats, tailgate, bows, and staves must be removed from the cargo bed and stowed.
Maintain the CTIS setting
Maintain the selected CTIS setting during the trip. CTIS settings must not be changed once the tire chains are installed.
Operational Impact of Cold Weather Tires
Make sure your tires have proper tread. Worn tires provide poor traction in snowy or icy conditions, making it more likely the wheels will slip. When operating in temperatures below 0°F, turn the CTIS OFF switch to the ON position during the first 5 miles of operation. This allows the tires to warm up and ensures a tight seal between tire and wheel. After 5 miles, turn the CTIS OFF switch OFF to enable CTIS operation.
Safe Driving Practices Fueling
Never fuel the vehicle when personnel are on board. If you need to refuel the vehicle while transporting troops, ensure that all personnel disembark prior to refueling. In the event of an emergency, such as a fire or explosion during refueling, you do not want anyone to be in the vehicle.
Vehicle Configuration Cargo Cover
Once the backrests and troop seats are installed, you have the option of using a cargo cover. The bows and staves that were installed for the backrest will be used for the cargo cover installation. On the MK23/25, the cargo cover is stowed in a storage bag located on the platform between the cab and the cargo bed. On the MK27/28, the cargo cover is stowed in the stowage box mounted on the left side of the vehicle. The cargo cover will normally be installed for troop transport.
Effect of Cargo on Vehicle Handling Stopping
Once the brakes are applied, the following factors all affect the distance required to stop a vehicle: Weather conditions Type of terrain Speed of the vehicle Weight of the vehicle Adding cargo to the vehicle increases the weight, which increases the required stopping distance. Cargo has a tendency to shift forward during deceleration. You should ensure that all cargo is properly secured. The heaviest cargo should generally be loaded toward the front of the cargo bed, although there may be exceptions for some containerized loads.
Driving In Icy and Snowy Conditions Reduced Visibility
One of the conditions you may encounter in cold weather is reduced visibility. Visibility can be reduced by blowing snow. Or you may experience fog as a result of warming temperatures. Turn on your lights so others can see you and always keep your windshield clean to maintain a clear field of vision. Snowy and icy conditions also cause trouble for other drivers. Be alert for signs that others on the road are having difficulty: Erratic driving Skidding Frequent braking
Container Cargo Quad-Con: Introduction
One quad-con unit is the same depth as the cargo bed (8 ft), approximately 5 ft wide, and 8 ft high. The MK23/25 is capable of carrying one quad-con pair (two quad-con units). The MK27/28 can carry up to one or two quad-con pairs (two or four quad-con units). The weight of a single quad can range from 1,800 lbs to 5 tons. When loading quad cons, be sure to remain within the cargo capacity of your vehicle for the terrain and the type of cargo you are transporting.
Operational Impact of Cold Weather Engine
Operating the vehicle in extremely cold temperatures can affect engine operation and related components: Coolant and washer fluid can freeze. Oil and grease can thicken. Rubber may crack and break more easily. Vehicle systems may not operate normally until they have warmed up. Engaging the ENGINE HIGH IDLE switch enables the engine to more rapidly reach operating temperature. This helps to alleviate the impact of cold weather on oil and grease viscosity, rubber items and other engine components.
Palletized Cargo Introduction
Palletized cargo can be defined as any cargo loaded on a pallet. Use of a pallet allows for: Ease of loading Ease of unloading Securing of cargo during transport This type of cargo can be transported with other cargo.
Safety Guidelines Troop Safety
Prior to departure: Verify troops are properly seated. Adjust cargo cover as necessary for proper ventilation. Secure the tailgate and troop strap. If required by the situation, verify that ear protection is available for each passenger. When driving, keep your attention focused on operating the vehicle. Avoid distracting conversation or any other activity that affects your ability to remain alert and drive safely.
Loading and Unloading Personnel Cargo Bed Preparation
Prior to loading personnel into the cargo bed, you are required to: Unload any cargo from the cargo bed Install troop seats and backrests, and ensure troop strap is available Ensure the tailgate and ladder are properly installed. Never allow personnel to ride in the cargo bed of a vehicle that is being towed. Be sure to follow all safety guidelines for transporting personnel
Safety Guidelines Introduction
Prior to transporting personnel: Ensure your vehicle is safe and properly equipped to handle personnel. Brief all personnel on safety requirements. Ultimately, it is your responsibility to deliver your passengers safely and on time to their destination.
