The working mode of CZJQZ-II continuous high-torque hydraulic bucking unit is full rotation mode, which greatly improves the speed of the makeup / breakout operation. This product is a new concept of hydraulic buckingunit product independently developed by our company. Compared with other forms of hydraulic bucking unit product, it has the following technical features:

1. Synchronized gripping force: The head-stock and tail-stock each contain five radially arranged heavy duty clamping cylinders (imported). It’s designed to ensure a continuous clamping range so as to achieve synchronized gripping force on the tools and precise axial alignment of the tools.
2. Enhanced work efficiency: The 360° continuous rotational head-stock enables the make-up and break-out of tools approximately 18 times faster than normal conventional head-stock design which are limited to a 40° rotation per time.
3. Reduces damage on work piece: With the unique continuous rotational feature, only one clamping action is required to achieve a 360° makeup / breakout of the thread. This greatly reduces the number of times the work piece has to be clamped, thus reducing clamping teeth marks and damage on the surface of the work piece.
4. Precise Torque Application: Fully imported hydraulic system ensures the accuracy of force applied on each piston cylinder, thus ensuring the precision of torque force on the tools during make-up and break-out.
