Abstract
The specification discloses an apparatus for easily and rapidly, yet securely, interconnecting two truck tractors by their fifth wheels to enable one tractor to tow the other tractor. More particularly the apparatus includes a beam fixedly secured to the towed tractor and a ramp secured to the towing tractor. The beam is slidably supported on the ramp so that the towed tractor rear wheels can be raised for towing by backing the towing tractor toward the towed tractor causing the ramp to lift the beam.
Claims14
A towing apparatus for interconnecting two truck tractors enabling one tractor to tow the other tractor, each of the tractors including a hinged fifth wheel, said apparatus comprising:
- a beam assembly including an elongated beam and a kingpin for securing said beam assembly to the towed tractor fifth wheel, said beam assembly further including means for securing said beam to the towed tractor at a location remote from the fifth wheel to fixedly secure said beam to the towed tractor, said beam extending rearwardly and downwardly from the tractor and terminating in a free end;
- a ramp assembly including an elongated ramp and a kingpin for securing said ramp assembly to the towing tractor fifth wheel for pivotal movement therewith, said ramp extending rearwardly and downwardly from the fifth wheel, said ramp supporting said free beam end for sliding movement therealong, whereby the rear wheels of the towed tractor can be lifted by backing the towing tractor toward said towed tractor causing said beam assembly and towed tractor to be lifted by said ramp assembly;
- and
- interlock means for preventing said beam and ramp from becoming disengaged.
An apparatus for interconnecting two truck tractors enabling one truck tractor to tow the other truck tractor, said apparatus comprising:
- an elongated beam member fixedly secured to the towed vehicle, said beam member including a remote end extending from the vehicle;
- an elongated ramp member secured to the towing vehicle, said ramp member slidably interengaging said remote beam end, said ramp member extending outwardly and downwardly from the towing vehicle, whereby movement of the towing vehicle toward the towed vehicle lifts said remote beam end and the towed vehicle, and whereby movement of the towing vehicle away from the towed vehicle lowers said remote beam end and the towed vehicle;
- and
- interlock means for preventing said beam member from being fully withdrawn from said ramp member.
A method of interconnecting two truck tractors for towing, said method comprising:
- securing a ramp member to the towing tractor, the ramp member extending rearwardly and downwardly from the towing tractor;
- securing a beam member to the towed tractor;
- positioning the ramp member under the beam;
- preventing the beam member from being fully withdrawn from the ramp member;
- and
- backing the towing tractor toward the towed tractor, forcing the ramp under the beam, causing the free beam end to travel upwardly along the ramp to lift the towed tractor for towing.
