The Power Tongs are designed for coupling the makeup of the sucker rod thread in oil well servicing operations. This hydraulic backup and main tong can be combined into a combined tong, making it easy to use. Different jaw plates are available for the main tong and backup tong, making it possible to clamp tubular columns and hoops of different specifications. The two gears have a great speed change difference, with the speed being high under high gear and the torque being large under low gear.
