PROJECT DESCRIPTION

ZQ203/100 drill pipe power tong is suitable for petroleum and mine drilling operation. Tong head is opening type, it can automatically release the drill pipe and its property is flexible.

This tong makes up or breaks out without any cat head, hanging tong and spinning rope (or spinning chain). The structure is the combination together with spinner and torque tong.

Using this tong can ensure safety, save labor force and enhance drilling efficiency. It is special suitable for frequent round trip and long drilling period.

This Tong Has Following Features:

(1) This tong simplifies hydraulic system because only hydraulic motor uses hydraulic power, other parts use compressed air.

(2) Upper tong integrates with lower tong to avoid twisting drill pipe in big torque operation and to prevent it slipping in neck.

(3) Workers operate it very convenient for shifting gear without power off.

(4) Automatic centralizing clamping mechanism can clamp new and old tool joint reliably.

(5) Air cylinder can push or pull this tong, saving labor’s force.

(6) Resetting and aligning the opening is convenient. Changing makeup to breakout is quick and reliable.

(7) Torque and speed can be controlled. It can get the biggest torque and the highest speed in clockwise or counter-clockwise.

(8) The clamping structure is simple. The clamping of upper tong and lower tong is accomplished by braking band and clamping cylinder respectively. Safety door can avoid tong head deforming in big torque operation (70-100 kN.m.).
