What is the mire resistance factor for a vehicle mired at wheel depth?

What is the mire resistance factor for a vehicle mired at tire depth?

What is the resistance factor for a vehicle when all of its tires are flat?

Proper snatchblock maintenance does not require lubrication after every use.

What is the gradient resistance factor for a casualty on a 15° grade?

What is the gradient resistance factor for a vehicle on a 60° grade?

The maximum structural rating of most wrecker booms is achieved at what angle?

A casualty weighing 12,500 lbs. on the front axle and a total of 25,500 lbs. on the rear axles, has gone off the road, down a 15-degree hard grass embankment. The resistance to be overcome will be approximately?

A 38,000 lb vehicle has gone off the road, down a 15 degree grass embankment that has become soft. The pull required will be approximately?

The use of a Snatch Block will increase the loads resistance.

Inspection of wire/web slings shall be made prior to use and annually, recorded in a written report.

Identify the gradient resistance factor for a casualty on a 30° grade.

Identify the gradient resistance factor for a casualty on a 45° grade.

A round sling used in a choker hitch has a rated capacity of what percent of its vertical hitch rating?

Extending the recovery boom without operating the winch will have what effect?

Sling angles less than what degree are not recommended for rigging?

Describe what a Running Block is attached to?

Describe what a Fixed Block is attached to?

A shipping container weighing 82,200 lbs. is on a 15° grade. One end of the container needs to be lifted, the low end needs to be raised one foot. The lift will require approximately how many pounds of force?

Inspection of web slings, shall be performed:

To multiply effort at the load, a snatch block could be employed.

A center drive style of winch, will pull less with a full drum of wire rope.

Which of the following should NOT be selected as a suitable anchor?

A lay up with one snatch block in it that is attached at an anchor will?

For casualties with static weights greater than 26,000 lbs., rigging attachments should be to the frame during recovery operations.

When towing a tractor/trailer combination, it is acceptable to connect the tow truck’s emergency air line to the tractor’s air supply system, and the tow truck’s service air line to the auxiliary braking unit.

Placing a towed vehicle’s transmission in neutral eliminates the need to disconnect a driveshaft prior to towing.

The boom elevation function on most hydraulic wreckers is designed to bypass or stall before damage to the recovery boom occurs.
