Abstract
An apparatus for loading and unloading containers of various sizes onto and off of a roll-off vehicle comprises a top frame and at least one lift actuator operable to pivot the top frame away from a horizontal home position to rearwardly incline the top frame. The top frame includes a main portion, a head portion longitudinally displaceable relative to the main portion, a plurality of sheaves, a cable extending through the sheaves, and a hoist actuator operable to displace the head portion between a retracted position and an extended position. The cable has a fixed end coupled to the head portion and a free end for coupling to a container. The hoist actuator is operated while the top frame is away from the home position to displace the head portion toward the extended position to load a container onto the vehicle, and toward the retracted position to unload the container.
