ZQ127/25 型鉆桿動力鉗
特點/Characteristics:
1、鉗頭采用了先進的卡緊機構，顎板與牙座為可分開式連接，夾持不同管柱時，更換牙塊與牙座十分方便。
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、兩檔變速，高檔速度快、低擋扭矩大，滿足不同管柱需求。
Four-gear rotation is adopted for large speed regulation range. And the rated torque is large.
3、鉗頭制動機構設置在鉗頭蓋板之上，調整、維修極為方便。
The braking mechanism set above the tong head cover.It’s convenient for adjustment and maintenance.
4、新型液動背鉗與主鉗配套形成組合鉗，操縱主鉗上的手動換向閥，背鉗即與主鉗同步夾緊或同步松開管柱，動作靈活可靠。
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、調整供油壓力，可以得到各種鋼級的油管上扣時所需的最佳扭矩。
Adjust the oil supply pressure, users can obtain the best make-up torque of various kinds oil tube.
6、可選配液壓吊筒，吊筒閥與手動換向閥緊湊連接，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、可選配扭矩控制系統，精確控制上扣扭矩。
Users can equip torque control system according to needs, which can accuracy control make-up torque.
8、本產品擁有多項國家專利。
This product has owned several patent of China
