  • Hoist for loading and unloading objects on a truck bed
    Publication number: 20080112786
    Abstract: A hoist for elevating cargo onto the bed of a truck includes a frame which may be mounted to the truck bed, a platform or container which is connected to the frame by a pivoting arm, and an arrangement of linkages for rotating the arm to position the platform either on the truck bed or on a loading and unloading position resting on the ground behind the truck. A threaded screw and an arm tube are connected to the arm via the linkages, with the linkages being arranged to increase the effective “flow” of the arm to provide a long travel distance of the arm. Rotational movement is imparted to the screw by electric, pneumatic and hydraulic systems to extend or retract the cantilever arm as desired.
