| description | A hydraulic torque wrench having a separate ratchet unit and hydraulic cylinder drive unit connectable by an overlapping cylindrical connection at selected angles of rotation providing clearance in use. The hydraulic cylinder actuates the ratchet mechanism by a connecting rod traveling through the overlapping cylindrical connection and engaging a pivotable drive plate. The ratchet may have a male drive shaft for driving a socket, or a female driver such a hex or spline wrench. The ratchet unit case may be integral, or split for removable accesses to the ratchet mechanisms. The cylinder unit hydraulic connections may be separate rotatable connections or a single connection and collar, allowing three-way rotation. Attachments for the hydraulic unit include a pipe flange spreader, a nut splitter, scissor action shears, and a lift/spreader for lifting an object from a flat surface or spreading surfaces apart. A reaction bar affixes to the drive unit body. |
