Hydraulic Push and Pull Device Testing for CZJ610-120 Make-up and Breakout Machine

The CZJ610-120 Make and Break Machine is an important equipment used to make up / break out and maintain all kinds of drill tools, drill stems and down-hole tools for petroleum and geological prospecting..It is also applied to the coupling screw of API thread tubings and casings .The operation mode of its rotary main tong is 360° rotation that increases the speed of make-up / break-out greatly. The floating arm tong is able to inspect the make-up torque precisely and display the torque of inflection point clearly during the make-up process. It changes speed automatically during the make-up process and the low rotation speed is lower than 1 r/min. It is thus applied to the processing demand of large torque.
