ABSTRACT:
A hydraulic powered wrench for fastening and unfastening a bolt, or the like, is presented. A wrench comprises a control valve capable of coupling hydraulic fluid to either of two hydraulic conduits, one on each side of a hydraulic piston within a hydraulic cylinder so that the control valve can move the piston linearly. A double ended socket, each end comprising a bolt receiving surface is utilized. Only a single positive drive is coupled to an external female spline and is coupled to rotate the socket in one direction only. A cylinder rod is coupled to and moved linearly by the piston and is pivotally connected to drive rotationally the drive arm via a female clevis wherein the drive arm is coupled to rotate the ratchet thru the positive drive which in turn is coupled to the socket.
