Abstract

The tool is a hinged triangle, of which one member is a hydraulic jack (8) and the opposed apex is a socket spanner head, reciprocating axial displacement of the jack (8) in conjunction with return spring (20) and ratchet (18, 19) applying successive incremental torque to the nut. Of the two fixed length sides of the triangle one is a lever (7) with an integral socket head and the other is a counter lever (6) fixing rotatably to jack housing and socket at its ends and also incorporating an anchorage at the former end. This anchorage is onto a central wheel bolt. Power is supplied from a slide valve controlled compressed air bottle.
