ABSTRACT:
A truck deck mounted cargo handling apparatus has a cargo carrier movable from a transport position resting upon a support frame to a loading and unloading position resting at ground level. In operation secondary lifting arms are moved to a lifting position by secondary actuators to move a first end of the cargo carrier toward a second end of the support frame. Primary lifting arms are then moved by primary actuators through a range of motion of at least 110 degrees to push the first end of the cargo carrier past the second end of the support frame and lower the cargo carrier to ground level.
