This wagon jack has an axle nut wrench attached to the top. In use, the axle nut would be removed, and held in the wrench by the clamping action of the sliding jaws. The whole tool would then be used as a jack (with the axle nut clamped in the upward facing wrench). After sliding off the wheel, lubricating the axle journal, etc. & sliding the wheel back on the axle, the steps are reversed. The wrench is removable and could be used separately.

A major point of the combination is to hold the axle nut without its having to be touched by the operator's hands.
