ABSTRACT:
An object loading and unloading apparatus of a type having a framework adapted to be connected to a truck bed. A track is connected to the framework, the track having a forward horizontal portion and rearward inclined portion. A frame having forklift members connected perpendicularly to the bottom thereof has four wheels adapted to ride on the track. Two of the wheels ride primarily on the inclined portion of the track and the other two wheels ride primarily on the forward horizontal portion of the track. The frame is movably mounted on the track so that in one position the forklift members are horizontal and can be driven under an object to be transported. A winch is connected to the framework and has a cable which connects to a pulley on the top of the frame for selectively pivoting the frame and forklift members and for pulling such frame and thereby an object on the forklift members onto the track and thereby onto a truck bed. The winch is further utilized for unloading the object by releasing the frame and allowing it to roll down the track by gravity to one position and then to pivot, also by the force of gravity, into an unloading position.
