ZQ203-100 drill pipe pliers are special equipment for unloading drill pipe and drill collar thread in oil and mine rig123.net' target='_blank'>drilling operations. It has the following characteristics:

1. The jaw and pneumatic combination clutch makes the shifting more stable and reliable.

2. High-strength alloy steel forgings are used for rafts, floating bodies and tongs, and have a long service life.

3. The surface of the main components are all nitrided, wear-resistant and corrosion-resistant.

4. Use high-quality high-pressure hose for long service life.

5. Select cylinders produced by professional manufacturers for long service life.

6. The clamp head is open type, which can freely disengage the drill pipe and has strong maneuverability.

7. The main pliers and the back pliers form a combination pliers. The upper buckle does not require a cat head, a lifting clamp and a rotating rope; and the possibility of the drill pipe bending under high torque is prevented and it is prevented from slipping in the slip.

8. It can perform non-stop shifting and freely adjust the high and low gears; the clamp head can generate the maximum torque and speed in both forward and reverse directions.

9. Automatic centering clamping mechanism ensures the new and old joints are tightly clamped.

10. Transfer cylinder, no need to manually push and pull the pliers.

11. Optional hydraulic cylinders.
