Patent ID: 8534978

Claim:
An apparatus for loading and unloading the bed of a light truck, comprising: a ramp extending from the bed to a ground surface to form an inclined plane thereto; a load resting on the ground proximate to the ramp; first winch and cable system attached between the load and the bed and configured to pull the load up the ramp and across the bed, said first winch and cable system powered by a first motor characterized by a first torque versus angular speed plot; a second winch and cable system attached between the load and the ramp and configured to pull the load off the bed and onto the ramp, said second winch and cable system powered by a second motor characterized by a second torque versus angular speed plot; and a means for cooperating operative between the first and second winch and cable systems to regulate the movement of the load along the bed and ramp and against frictional and gravitational forces encountered thereupon exclusively by self-adjustment of the systems, said means comprising a convergence of the first and second torque versus angular speed plots at a preferred speed, wherein the means for cooperating further comprises the second winch free-wheeling while the first winch is pulling and the first winch engaging in reverse while the second winch is pulling.
