ABSTRACT:
A recovery unit for use by one truck tractor in towing another disabled truck tractor has an anchoring frame assembly with a king pin for coupling to a fifth wheel of the towing tractor and an attaching frame assembly with a king pin for coupling to a fifth wheel of the disabled tractor. The attaching frame assembly is mounted for pivotal movement relative to the anchoring frame assembly between stored and extended conditions. Actuating cylinders and an auxiliary frame assembly are selectively operable to pivot the attaching frame assembly relative to the anchoring frame assembly between the stored and extended conditions and to pivot the attaching frame assembly to and from an erected position relative to the anchoring frame assembly once the attaching frame assembly has been first moved to its extended condition and coupled to the fifth wheel of the disabled tractor. When the attaching frame assembly is moved to its erected position, this results in the frame of the disabled tractor being placed in a raised towing position. In the erected position, the attaching frame assembly can be rigidly locked to the anchoring frame assembly to form a rigid beam extending between and interconnecting the respective fifth wheels of the tractors.
