ABSTRACT:
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.
