Casing Power Tongs

Driven by hydraulic motor, the casing power tong of TQH340-35 series can reduce the labor intensity of oilmen to the greatest extent. Besides tubes with the diameter from 140mm to 340mm (5.1/2-13.3/8in.), this well head drilling equipment can also be used to fasten the pipe of Φ340-Φ406 (13.3/8-16in.) by changing toothed ring and jaw plate. Uniquely designed, this casing power tong is quite flexible for use. The length of the force arm is 813mm (32in.) and the maximum torque of the hydraulic driven tong is 35kNm (25,000lb/ft).
