True
T or F: On a vertical mast lift are the two front wheels the only ones equipped with the brake?
True
T or F: With a telehandler, before raising the boom to pick or place loads, it's very important to ensure that your unit is level both laterally, or side to side, and longitudinally, meaning front to rear
True
T or F? bridge plates and dock baords have capacity ratings
True
True or False: An added attachment will normally reduce the forklift lifting capacity?
True
When equipped only with forks, counterbalanced forklift are ideal for pulling and pushing loads across smooth surfaces
True?
On a vertical mast forklift the drive wheels and axle are located
at the front of the unit
T or F: ROPS will still work if you don't wear a seatbelt
false
stand up models
for use in tight spaces
When fuel, oxygen and ___________ mix together in the proper proportions, they will cause a fire
heat
Under normal operating conditions, the location of the fulcrum is:
located at the front of the wheels or outriggers
Free light is the distance your forks can travel upwards from the ______ without the second stage of your mast increasing height
lowest point/ground
When driving a forklift near the edge of a loading dock, always
maintain a safe distance away from any elevated dock, ramp or platform edge
The data plate must always be able to inform you
max allowable load weight and lift height
Roll Over Protective Struction (ROPS)
only found on units with side mounted compartment
The use of special attachments will
reduce the weighted capacity of the forklift
What kind of tires are found on forklifts?
solid, cushion, pneumatic
When travelling down a ramp or slope with a load, the load must be on the:
uphill or upgrade
If you cannot clearly see your path or travel when driving forward or in reverse you should
use a spotter
Mechanical Capabilities and limitations:
- Max allowable load weigh -Rated load center distance -Max lifting height - United weight - Lifting attachments and relevant load capacity variations
Tilt cylinders
- attach to the upright channels - activated from cab - extend or retract and tilt - double action, two way -both extend and retract functions are hydraulically powered
When unloading from a big ass trailer it's important to
- block the trailer wheels - support the trailer - inspect/check dock boards -check clearance - ensure adequate lighting - ensure adequate air quality - avoid driving along the edge - cross bridge/ramp plates squarely and slowlye
To travel up the ramp with a load that obstructs your vision, it should be driven forward using a signal person to guide you
- block the wheels if it becomes necessary to stop while on the ramp - remember the stability pyramid
When parking propane powered units indoors for more than an hour
- close the cylinder primary shut off valve - wait for the engine to stall - switch the key off
Solid tires
- hard solid rubber - pressed on to the wheel hub - no tread - Primarily used indoors on hard, level, improved surfaces such as concrete
Cushion Tires
- hard solid rubber core - provides a smoother ride and improved traction - designed for indoor use but could be use on improved outdoor surfaces such as asphalt
Electric batter powered forklifts should be:
- placed on charge while parked - have the battery disco if left unattended
When parking your forklift, after choosing a proper location you must:
- set the park brake - retract/lower the forks or attachments until they are flush on the ground - place the transmission in neutral, shut down the engine
what are outriggers used for?
- to provide greater stability to uneven grounds
when travelling up or down without a load you should drive with the forks facing down grade
- travel in reverse up the ramp and forward down the ramp
Sitdown types
-have 4 wheels -also have 3 wheel versions greater maneuverability
When approaching a load with your forklift
-visually inspect the integrity of the load -be sure the proper attachment will be used - determine the weight of the load - check the load dimension
The minimum approach distancde to energized power lines is:
10 feet, 3 meters
What load center rating does most forklifts have?
24 inch (600 milimeters) some can have 36 inch (900 mm) 48 inch (1200 mm)
A forklift is considered unattended when the operate is
25 feet away (8 meters)
With vertical mast forklifts, one the load is engaged, and if you have clearance, raise the load _____________ before tilting the load and retracting the boom or backing up
3-4 inches ( 8 to 10 centimeters)
For telehandlers which type of steer is for loading position and tight maneuvering only?
Circle Steer
counterbalance forklift fall under
Class 1,4,5,7
rough terrain forklifts fall under
Class 7
Most common type of forks
ITA & Shaft
You have been tasked with moving construction materials with a telehandler forklift across your jobsite. It's going to require that you transport those loads across rough terrain with various grades and slopes. Which of the following statements is the correct safe practice for performing this task?
Keep the load uphill when driving up or down slopes. When unloaded keep the forks downhill and slightly tilted down
turning the forklift causes the CG or the CCG to move _______ from the center in the ___________ direction of the turn
Outward, Opposite
the point where a forklift is designed to lift it's maximum rated load is called the:
Rated Load Center
T or F: With no load, a forklift's CG is located near the heavy counterweight toward the rear of the unit?
TRUE
It is good practice to avoid handling double-stacked loads
YES
As the Mast tilts, the CG or CCG ________.
moves forward and back
As the mast raises and lowers, the CG or the CCG also ___________.
moves up and down
What does the counter weight do?
offsets the weight of the laod and prevents the unit from tipping forward
Vertical mast forklifts forks must engage at least _________of the load being handled at all times
two-thirds (2/3)
Pneumatic Tires
- Filled with air, nitrogen, liquid ballast, or foam - designed for outdoor applications on non-improved road surfaces such as compacted road base
ROPS
- designed to protect reduce the risk of injury - MUST wear a seatbelt
Diff styles of Forks
- lumber - folding -gypsum -drum -block -spark retardant
If tip over occurs
-make sure seatbelt is fastened -brace your feet -hang on to the steering wheel -leanaway from impact side -STAY IN THE CAB
Specialized Forklift Attachments
