Abstract

A parallel shaft strap tie down apparatus and system. Exemplary embodiments include a parallel shaft strap tie down apparatus and system for vehicle transports. Exemplary embodiments include a central shaft having a ratchet wheel and a pawl configured to wrap a strap around the central shaft. A parallel shaft is positioned parallel to the central shaft. The strap can be inserted between a variable gap between the central shaft and the parallel shaft. When the central shaft is rotated the strap is wound around the central shaft and the parallel shaft, both of which cooperate to create a self-tightening response of the strap on the central and parallel shafts.
