The Drill Pipe Tong is applicable for the petroleum and mine drilling,it is safety and labor saving,and improving the working efficiency.The tongs have the following features:
　　◆ Using pneumatic power to shift and drive backup tong.
　　◆ It is integral mechanism made by spin tong and torque tong.
　　◆ Changing gear allowed during operation.
　　◆ New or old drilling pipe joint could be clamped reliably.
　　◆ Both direction could run the maximum torque and rotation speed.
