Abstract: An apparatus designed to aid in the winding of cargo straps used on flatbed trailers of tractor-trailer rigs comprising a metal cylinder with an internal power/spiral spring is herein disclosed. A first end of the cylinder is closed with an outer spring case while a second end is slipped through a standard cargo strap winch bracket system commonly found on conventional flatbed tractor-trailers. A similar arrangement is used on all cargo straps systems on a truck. The user pulls out enough strap to anchor on an opposite side of the truck and over a carried load. The strap is then tightened and cinched down in a conventional manner. When unloaded, a lever is released, and the entire cargo strap is quickly retracted back onto the winch shaft. This not only represents huge timesavings for the truck driver, but also protects the stored cargo strap from damage.
