ABSTRACT:
A truck platform is elevated at one end and then moved rearwardly by pulsation cylinders which slowly accelerate and then rapidly decelerate the platform and truck. The abrupt deceleration causes the material in the truck to continue to move rearwardly separating from the truck floor and move out of the truck in a stair step fashion through repeating pulsations. The angle in which the platform needs to be raised is minimized by the application of pulsation forces to the system thereby improving the safety and ease of unloading the truck.
