Huludao Boyu petroleum machinery
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).
YNJQ300 hydraulic bucking machine has four hydraulic sycliders, in working, the pipe is fixed, the four hydraulic cylinders synchronized able to clamp the coupling and rotate continuousely. The reliable synchronizer is imported from
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.
