ABSTRACT:
A draw bar replacement strap and method for temporarily coupling and moving a disabled railroad car without actuating the drawbar. The strap comprises an elongated, multi-section, multi-ply body extending between a terminal two ply eye through which the strap may be looped and a remote tail. The strap is integrally formed from an elongated, single ply that is appropriately looped and folded. A ratchet system is attached to the strap for tightening. An auxiliary pad is provided for preventing abrasion of the strap when deployed, and for restraining the strap when stored. A multiple ply section forms the eye and extends from the eye to an end journalled to the ratchet. An elongated, double ply body section extends between the ratchet journal and the tail. Through the multi-ply multi-segment structure the tow strength of the cable is vastly improved. In the method the strap is coupled around the towing drawbar, and the tail and ratchet are drawn through the eye. The tail is wrapped over the wear pad and around a drawbar of the disabled car, passing through the slot in the ratchet take up spool until the multi-ply body portion of the strap contacts the take up spool. Optionally the strap may be looped about a captivated ring.
