PREPARE TOW BAR ASSEMBLIES
All persons not involved in the loading or unloading operation must
stand clear of prime mover and fifth wheel towing device. Failure to comply
may result in death or injury to personnel.
Due to the dimensions and center of gravity of some loads, proper
procedures must be followed when loading and unloading equipment to
prevent damage to equipment and injury or death to personnel.
Visibility from the prime mover is significantly reduced when backing,
whether the fifth wheel towing device is loaded or not. Proper procedures
must be followed and extreme caution used when backing to prevent
damage to equipment and injury or death to personnel.
Use extremely low speed when loading and unloading vehicles. Higher
speeds will exaggerate motions and create hazardous conditions, which
could result in personnel injury or death or damage to equipment.
Tow bar assemblies weigh 47 lbs. Use an assistant and caution when
removing and handling them to prevent injury or death to personnel and
damage to equipment.
Refer to WP 0091 for authorized prime movers and towed vehicles.
Prime mover and disabled vehicle should be on the same plane when
coupling. If planes are uneven, use winch to maneuver disabled vehicle to
even plane with prime mover.
If the vehicle being recovered is not equipped with front towing eyes, skip to step b.(2)
1. Tow bar assemblies should be in stowage position.
2. Remove spring pin (1) from hitch pin (2) and remove hitch pin from upper section of tow bar
assembly (3). Set aside hitch pin (2) for future use.
