Rail Wrenching Machine is a tool used to provide grip and mechanical advantage in applying torque to turn objects-usually rotary fasteners, such as nuts and bolts-or keep them from turning. Higher quality wrenches are typically made from chromium-vanadium alloy tool steels and are often drop-forged. They are frequently chrome-plated to resist corrosion and for ease of cleaning.
Drilling rig automation is one of the key issues for the future of safe and economic drilling operations. Tripping, as well as casing and tubing running operations, represent the considerable amount of total rig time of more than 30%. These operations incorporate the risk of possible accidents due to the manual work involved.
