2. Equipment Composition And Main Performance Discription.
l Master tong use closed-head tong to clip coupling,it can’t move with the thread joint.
l Master tong is drived by hydraulic motor,it may rotate bi-direction,and two-range planetary gear drives.
l Clamping way:three jaw set clip through roller climbing.There are 9 jaws evenly clip the coupling in the circle direction.Along with the torque change,the clamp force changes in direct ratio.
l Photoelectric measurement port is set on master tong to count the number of turns.Which can give a measurementsignal per 3 degree so as to collect speed signal and turns number signal.
l Backup tong use closed-head tong to clip pipe,it may move with the thread joint.
l Backup tong clipping and the initial clamp force is powered by cylinder.
