The YNJQ series bucking machine has features of the power tong of the machine can rotate to make up or break out the coupling,  no need to change the jaw for different pipes, and can be used for both API & Premium connection(VAM, MEW VAM).

YNJQ590 hydraulic bucking machine has six hydraulic sycliders, in working, the pipe is fixed, the six hydraulic cylinders synchronized able to clamp the coupling and rotate continuousely. Every cylinder control one jaw, and every three cylinder move synchronously, so it can be used for both big and small workpiece;for small pipes, only three jaws sretch out to clamp the coupling, and for big ones, it is six. The reliable synchronizer is imported from Italy. To adjust the center automatically, the backup tong can move a bit. The clamp force is controlled by the hydraulic system.

This structure has features of large apllication, High mechanical strength, reliable Clamping, no-skiding, no- pipe damage, small die marking to API, high automation, double pump speed, quick making up, slow torque increasing, and it can be used for premium connections.
