A hydraulic torque wrench system has a power head and interchangeable link cartridge drives, insertable into the power head. A power head to cartridge drive connection system secures the cartridge drives into the power head forming a single unit having a torque line extending through the center line of the power head, in order to eliminate adverse reactive forces. A hydraulic hose coupler allows 360° by 360° coupler rotation. The link cartridge drives include a reaction pawl which controls the movement of the ratchet within the cartridge drive, a clam shell drive plate for an internal ratchet tooth cassette, a locking system to maintain a ratchet square drive in opposed lateral positions, and a reaction arm adjustment system for locking the reaction arm in a plurality of configurations in relation to the cartridge drive. |

1. A hydraulic torque wrench system comprising:
a hydraulic wrench power head comprising a longitudinal axis extending along the center line of the power head, a port stem component having a port stem base section located on the power head, a port stem section extending up from the port stem base section, and a port block connected to hydraulic hose couplers, said power head having a forward connecting component and a rear connecting receptacle, the forward connecting component and the rear connecting receptacle being located on the center line of the power head; and a plurality of different, interchangeable link cartridge drives for insertion into the power head, each cartridge drive having a longitudinal axis, a forward connector, and a rear reaction pin, whereby upon insertion of one of the plurality of cartridge drives into the power head, the reaction pin of the cartridge drive engages the connecting receptacle of the power head and the forward connecting component of the power head attaches to the forward connector of the cartridge drive, forming a single, integral hydraulic torque wrench unit with the longitudinal axis of the power head being parallel to and aligned with the longitudinal axis of the cartridge drive and the torque line of the unit extending through the center line of the power head and rear reaction pin of the cartridge drive. |
