ABSTRACT:
An apparatus for assisting with the handling of a door of a tailgate cart features two springs that are strung in seriatim. The first spring is connected at one end to the tailgate door, and connects to the second spring at its other end. The second spring is anchored at a distal end to the frame of the tailgate cart. The first spring has a shorter length than the second spring. As the tailgate door is pivotally lowered from its upright position, the shorter spring provides a matching small force. As the tailgate door reaches the end of its travel, the second spring adds its force to the first spring, and a greater force is provided to counterbalance the door.
