A spare tire winch mechanism which performs the steps of lowering the spare tire from its location and locating the flat tire on this location via a rope winding assembly. A worm gear and a threaded drum prevent the rope from winding onto the threaded drum in an overlapping and irregular manner which results in locking of the parts and the damage to the parts due to the application of extreme force during the winding. The spare tire performs free fall movement with its own weight as a result of the tire wrench being activated with a pulling force applied perpendicular to the floor axis and the worm gear disconnects from the drum body, in case one of the tires of the motor vehicle needs to be changed.

An elongated cam pin for use in a clamping assembly, the pin comprising a first half-round portion and a second half-round portion laterally offset from the first half-round portion, wherein the centers of the first and second half-round portions are spaced-apart a distance S along a diametral center line of the pin, wherein each of the half-round portions has a radius R and a diameter D equal to 2R, and wherein the ratio D/S is between approximately 2 and approximately 3. In one embodiment the ratio D/S is approximately 2.3. In some embodiments rotation of the cam pin within the clamping assembly is actuated by a shaft having a relatively short stroke length. In some embodiments the cam pin is rotatable within the clamping assembly through an arc of up to approximately 40. In some embodiments the actuating shaft is movable within the housing of a compact locking apparatus to cause the clamping assembly to releasably engage a restraint cable in a self-gripping fashion. In some embodiments the locking apparatus may be used in a locking system designed to safely lock a suspended load at a desired location relative to the cable. In some embodiments the cable is at least one inch in diameter and the diameter D of each of the half-round pins is approximately 1.75 times the diameter of the cable. In some embodiments the suspended load may comprise a bin floor and any supported lumber travelling between loading and discharge positions in a lumber sorting apparatus.

Provided is an improved come along device with a handle, a release trigger for a stop pawl, and a push tab for a release pawl. The handle may allow an operator to better grasp the come along device. The release trigger allows an operator to release tension in a cable by disengaging the stop pawl when the trigger is pulled and engaging the stop pawl when the trigger is released. The push tab allows an operator to disengage the release pawl when the push tab is pressed and engage the release pawl when the push tab is pulled.
