Abstract: The load-tie-down system of the invention includes a load-supporting structure having a side support and a second support. A winch assembly is operably mounted on the load-supporting structure and includes a winch frame having a crosspiece and two struts projecting downward from the crosspiece. A winch drum is rotatably mounted between the two struts of the winch frame and a belt is attached at one end to and wound around the winch drum. A hook is attached to the free end of the belt. The belt is anchored by the hook attaching to an anchor located on the winch frame. The anchor includes a bar on the winch frame around which the hook may fasten. A lock to restrain the rotation of the winch drum is also included having a ratchet wheel attached to the winch drum and a pawl pivotally attached to the winch frame. The winch drum and anchor are located so that the belt may extend around the crosspiece and a load and then anchor on the winch frame.
