，ZQ203/125）；
可不停车换档（ZQ162/50A，ZQ203/75X，ZQ203/100，ZQ203/125）；
新旧接头均卡紧可靠；
正反方向都可产生-大扭矩和转速（除CHKQ203/75外）。
注：ZQ203/75X和ZQ203/145X型采用行星爪夹紧机构，在适应范围内不需要更换任何零件。
CHKQ203/75型为斜井钻机专用钻井钳，钳体-大移送距离700 mm，钳体升降范围0~360 mm，一次冲扣转角30°，适应斜井角度0～45°。
The Drill Pipe Tong is applicable in 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 （ZQ162/50A，ZQ203/75X，盐城特达钻采设备有限公司,盐城特达|||Slant hole钻杆钳
,盐城特达,ZQ203/100，ZQ203/125）.
It is a integral mechanism made by spin tong and torque tong（ZQ162/50A，ZQ203/75X，ZQ203/100，ZQ203/125）.
Changing gear allowed during operation（ZQ162/50A，ZQ203/75X，ZQ203/100，ZQ203/125）.
New or old drilling pipe joint could be clamped reliably
Both directions could run the maximum torque and rotation speed（except CHKQ203/75）.
Remark:Model ZQ203/75X and ZQ203/145X: using planet claw, needn’t to change any parts in application range.
Model CHKQ203/75 drill pipe tong used Specifically for slant hole drilling rig,maximum thrust distance of tong is 27″.Rise and fall range of the tong is 0~14″.Washed-up corner one time is 30°.The available corner of inclined well is 0～45°.
