发明名称 Cable bolt driver
摘要 A cable mine roof bolt driver is disclosed for rotating a cable mine roof bolt in resin grouted applications. The bolt driver includes a body having a front face and a rear face. A cable receiving bore is positioned within the body extending into the body from the front face. The cable receiving bore is adapted to receive a cable of the cable mine roof bolt therein. A cable engaging device is provided within the cable receiving bore for rotatably engaging the cable such that rotation of the body will rotate the mine roof bolt when the cable engaging device has engaged the cable. A body rotation mechanism is coupled to the body for providing rotation of the body of the bolt driver. The cable mine roof bolt driver of the present invention can be utilized to rotate conventional cable mine roof bolts in resin grouted applications.
