ABSTRACT:
A strap extending and tensioning system includes a strap winding mechanism to wind a predetermined length of strap on itself. A clevis slip hook is included for coupling to a rear end of a tow truck or the like. A strap tightener allowing the strap to be tightened passes through a through slot in the strap tightener. The strap tightener has a rotatable handle to rotate counter-clockwise a pair of ratchet wheels and a shaft to wind the strap on the shaft and thus place the strap in tension loading. Two pawls, as part of a pawl plate in the rotatable handle, may engage the ratchet wheels to rotate counter-clockwise through a biasing spring which pushes the pawl plate in a predetermined direction. The shaft can wind the strap to tighten it when the displaceable handle is rotated to provide a counter-clockwise rotation of the shaft.
