A track and trolley assembly for use with a tarpaulin enclosing system on a flat bed trailer comprises a plurality of trollies for operatively supporting the tarpaulin enclosing system, each trolley having a frame member, at least one weight-bearing roller mounted on the frame member for rotation about a substantially horizontal axis and at least one stabilizing roller mounted on the frame member for rotation about a substantially vertical axis. An elongate track has a length, a substantially vertical trailer mounting face, a substantially horizontal weight-bearing roller receiving surface disposed along the length of the elongate track means, and at least one substantially vertical stabilizing roller receiving surface disposed along the length of the elongate track. A rail is disposed substantially along the length of the elongate track and has a length, a substantially vertical trailer mounting face, and a hook-receiving rail portion disposed in laterally outwardly projecting cantilever relation from the trailer mounting face so as to be free and clear of the substantially vertical trailer mounting face, and disposed above the substantially horizontal weight-bearing roller receiving surface of the elongate track and above the at least one substantially vertical stabilizing roller receiving surface of the elongate track, for receiving at least one tie-down hook in releasably retained relation therealong. The trollies move along the elongate track, such that the frame members of the trollies are disposed horizontally outboard of the hook-receiving rail portion of the rail.
