An winch drum for a winch used to secure cargo straps which restrain cargo transported on a flatbed vehicle. The winch drum has two D-shaped sections arranged with the flat surfaces spaced apart and facing each other to form a slot for receiving the end of a cargo strap. The arcuate surfaces of the drum sections form a generally cylindrical surface on which the strap can be wound. The flat surfaces of each drum section are formed by inturned sides which are butted together edge to edge. Each drum section has notches at the ends of the flat surfaces. Reinforcing plates are secured in the winch drum by welding them to the drum sections adjacent to the notches. This construction exhibits strength because the reinforcing plates resist any tendency for the tubular drum to collapse.

[ Having thus described the invention, what is claimed is:] [1.] A winch construction for a cargo tie-down system used to secure cargo on a vehicle and including a flexible strap having opposite first and second end portions with said first end portion secured to the vehicle and the strap drawn over the cargo, said winch construction comprising:a winch frame secured to the vehicle;a winch drum which includes a pair of opposing drum sections having arcuate outer surfaces cooperating to provide a generally cylindrical drum surface on which the strap can be wound and generally flat surfaces spaced apart and facing one another to present a slot through said drum for receiving the second end portion of the strap, said flat surfaces terminating in opposite ends;a pair of reinforcing plates secured to said winch drum adjacent said opposite ends of the flat surfaces to reinforce and strengthen the winch drum and present boundary surfaces at opposite ends of said slot, said plates occupying planes oriented substantially perpendicular to the axis of said generally cylindrical drum surface and each reinforcing plate having a substantially circular shape and a perimeter located adjacent to said drum sections;means for mounting said winch drum for rotation on the winch frame;a ratchet wheel carried on said winch drum and presenting peripheral ratchet teeth; anda pawl having a plurality of pawl teeth, said pawl being connected with said winch frame for movement between an engaged position wherein said pawl teeth mate with said ratchet teeth to lock the winch drum against rotation in a direction to unwind the strap from the drum, and a release position wherein the drum can rotate.
