ZQ127/25 型钻杆动力钳
特点/Characteristics:
1、钳头采用了先进的卡紧机构，颚板与牙座为可分开式连接，夹持不同管柱时，更换牙块与牙座十分方便。
The tong head used inner curved roller climbing and clipping mechanism and needn’t to change any part during making up or breaking out the tubing thread.
2、两档变速，高档速度快、低挡扭矩大，满足不同管柱需求。
Four-gear rotation is adopted for large speed regulation range. And the rated torque is large.
3、钳头制动机构设置在钳头盖板之上，调整、维修极为方便。
The braking mechanism set above the tong head cover.It’s convenient for adjustment and maintenance.
4、新型液动背钳与主钳配套形成组合钳，操纵主钳上的手动换向阀，背钳即与主钳同步夹紧或同步松开管柱，动作灵活可靠。
The new hydraulic backup tong and the master tong form a combined tong, operate the control valve on the master tong, the backup tong will automatically clip or simultaneously loosen the tube pillar.
5、调整供油压力，可以得到各种钢级的油管上扣时所需的最佳扭矩。
Adjust the oil supply pressure, users can obtain the best make-up torque of various kinds oil tube.
6、可选配液压吊筒，吊筒阀与手动换向阀紧凑连接，便于操作。
Users can equip hydraulic suspension according to needs, the suspension valve compactly contact with hand control valve, so it is easy to control.
7、可选配扭矩控制系统，精确控制上扣扭矩。
Users can equip torque control system according to needs, which can accuracy control make-up torque.
8、本产品拥有多项实用新型专利（专利号：ZL202322919554.9等）。
This product has owned several patent of China（Patent NO. ZL202322919554.9 etc.）
