Abstract
A power-operated wrench for tool joints such as for drill collars and other tubes in rotary drilling of oil wells consists of two parallel identical clamping chucks which can be turned relative to each other by a power ram. Each chuck includes a carrier with a jaw in a U-shaped recess, and a closer with a facing jaw in another U-shaped recess and a closer with a facing jaw in another U-shaped recess which is hinged to two power rams. The drill collar and tool joints can pass through the opened up closer without having to remove the wrench, thus shortening the time for the coupling and uncoupling operations. The torque drive is well balanced. The wrench can operate for long periods without servicing or overhaul.
