Abstract
A towing apparatus removably attachable to the fifth wheel of a towing vehicle includes a forward lifting beam having a distal extremity and a proximal extremity having a flat mounting face angularly disposed to the long axis of the beam and adapted to engage the fifth wheel. A rear lifting beam has a first extremity pivotably joined to the distal extremity of the forward lifting beam, and a second extremity attachable to the fifth wheel of a disabled tractor. A hydraulically activated piston, located in the forward lifting beam causes movement of the rear lifting in a vertical plane.
Claims12
Towing apparatus removably attachable to the fifth wheel of a towing vehicle, and adapted to engage a disabled tractor having a fifth wheel, said apparatus comprising:
- a) a forward lifting beam elongated between proximal and distal extremities, said proximal extremity having a flat mounting face angularly disposed with respect to the direction of said elongation and having a downwardly directed first coupling fixture,
- b) a rear lifting beam elongated between first and second extremities, and having upper and lower surfaces, said first extremity being pivotally joined adjacent said lower surface to the distal extremity of said forward lifting beam, and said lower surface having adjacent said second extremity a downwardly directed second coupling fixture, and
- c) hydraulically activated piston means associated with said forward lifting beam and pivotally interactive with the first extremity of said rear lifting beam adjacent the upper surface thereof in a manner to effectuate powered pivotal movement of said rear lifting beam in a vertical plane.
