Site and Crane Set Up

To minimize the risk of personnel being struck or crushed:

Barricades or barriers must be erected around the swing radius of the outermost rotating part of the crane

When setting a crane up on outriggers, the tires of the crane should be:

Be just high enough off the ground to relieve the tires of crane weight with load applied

Which is the most common cause of death to crane operators?

Crane turnover

When working at ground floor level near a cellar wall, the crane's outrigger pads or tracks shall be placed:

At least as far back as the depth of the wall below the ground

If the cranes level indicator is broken, you can use a torpedo level to level the crane:

True

Once the crane is set up and leveled, the levelness should be checked regularly during crane operations:

True

The hoist line can be used as a plumb bob to check levelness when the crane is on outriggers:

True

When working near a dangerous area, it is best to have the crane positioned so the operator is in a position to continually observe the danger area:

True

You should try and position the crane so that the load is initially lifted from the least stable area of the crane and swung to the most stable area:

True

What is the minimum clearance of the counterweight swing?

Two feet

The operator must ensure the blocking or cribbing is level and the outrigger pads or floats are at a degree ____ angle to the outrigger jacks:

90

A job site chart or drawing:

A chart or drawing of the job site showing obstacles. lift areas. under ground structures and other pertinent information relating to the job site conditions

What are the primary things you look for when arriving on a job site?

Access. room to set up the crane. ground stability and obstructions

The person responsible for performing the lifting operation must:

Ensure there is adequate access to the job site set up area and no obstructions. Avoid trenches, excavations, back fill areas around buildings and shoring locations. Avoid set up over underground pipe, manholes and structures

As long as the crane shows level over the rear, it is not necessary to check for levelness at a ninety degree or over the side:

False

It is not necessary for pads or floats to be locked to the outrigger jacks when outriggers are in use:

False

When using outriggers the crane's tires shall still touch the ground:

False

Blocking (cribbing) may be placed under the outrigger beams:

Never

When is it allowable to block or crib under the outrigger beams?

Never

When blocking up under the outriggers how much space is allowed between the blocking or cribbing?

None. the blocks or cribbing should be tightly together

A crane is set up with three of it's four outriggers fully extended, with the fourth retracted. The capacity of the crane in this configuration will be found in the:

On rubber chart

How many degrees out of level are you allowed?

One

Within what percentage of levelness does a telescoping boom crane have to be for the gross capacity in the load chart to remain valid?

One

The cranes load chart capacities are based on the crane being level within:

One percent

The first layer of cribbing or blocking should run _______ with the crane:

Parallel

If set up requires working around a retaining wall or excavation, what is the minimum set back distance?

Ratio of one to one

The second layer of blocking or cribbing should run at _______ with the first layer or tier:

Right angle

According to OSHA, accessible areas of the operating crane must be barricaded within:

The swing radius of the rear of the rotating superstructure

Blocking or cribbing should be thick enough and long enough to support the outrigger pads or floats and transmit the load to the supporting surface. The blocking or cribbing surface area should be at least times larger than the surface of the pads or floats:

Three

When using a crane with on rubber capacities, it may be necessary to place cribbing under the ______ to get it level:

Tires
