product name: Hydraulic bucking unit
Hydraulic bucking unit is an important equipment to make up, break out and maintain drilling tool, pipe string or the thread connection of downhole tool in petroleum exploration. Considering the current state of petroleum industry, our YCJ—25 hydraulic bucking unit absorbed the advanced technology of foreign product and  priored to other same product at home. The platform had compact design. Surface of the platform is made of operating handle, torque metre and hydraulic pressure gauge. The bottom of surface is hydraulic pipeline, the end is electric hydraulic pump.
The product possessed some advantages.
                         i.            High level automation and easy operation.
                       ii.            Two persons can accomplish the make-up/break-out of tools.
                      iii.            High pulling torque when making up.
                     iv.            Adapted to wide range diameter
                       v.            Quick spinning and axial thrust
                     vi.            Do not need to change tong head while using.
