ABSTRACT:
The fifth wheel release tool is a device for applying the required force for releasing the latch mechanism of the fifth wheel hitch securing a semi-trailer to a truck tractor. The release tool has a hook which is removably secured to the hitch release handle, a non-resilient line extending from the hook, a treadle or stirrup secured to the opposite end of the line from the hook, and a saddle which is removably secured to a relatively fixed structure and over or through which the flexible line runs. This assembly transfers the tensile force applied to the release handle from the horizontal to the vertical as the flexible line passes over the saddle component. A person using the present release tool need only apply one's weight to the treadle or stirrup, in order to apply sufficient force to release even a relatively sticky hitch release.
