Abstract

A powered loading system is disclosed for loading and unloading a heavy load-carrying module onto a vehicle for transport. The module is supported for movement on casters and, additionally, it includes rollers and a slotted probe member. The transport vehicle for receiving the module includes ramp members for engaging the rollers on the module. A motor on the vehicle is coupled to a jackscrew which is attached to a movable block member. A hook member is supported on the block for displacement in an arcuate path normal to the ground plane. With the rollers on the module in position on the ramp members and deplacement impending, when the motor is actuated, the hook member engages and disengages with the slotted probe member for raising and lowering the module for, respectively, loading and unloading the module on the transport vehicle.
