Yanker Tool

the yanker tool (patent pending) performs the ‘up-over-and out’ motion the jost© safety catch 5th wheel release mechanisms require at uncoupling. simply hook the ‘thumb’ of the yanker into the jost© release pull handle, set the ‘foot’ of the yanker onto the frame rail, turn it like a key, and then pull outward as usual. with the yanker this release operation is performed close to your body, while standing upright, beside the rig instead of beneath it, all while maintaining stable footing.
