ABSTRACT:
A truck dumping and unloading apparatus which is operated by reverse truck motion and is adapted for mounting on a flatbed truck or a pick-up truck. The apparatus includes a single or double-member, open-top sled having at least a primary compartment adapted for containing trash, garbage or refuse, a sled guide mounted on the back of the truck for receiving a cable, one end of which cable is attached to the sled and a traveling block adapted for traveling on the opposite end of the cable and receiving a pair of tire chains or friction mats for deployment beneath the rear wheels of the truck. Operation of the truck rearwardly and traversal of the tire chains or friction mats by the rear truck tires causes the traveling block to traverse the cable and the sled to slide from the truck bed and dump the trash, garbage, bulk materials or refuse, reponsive to tension applied to the cable by the travelling block.
