Lord, matching clamp back, reversing valve can be manually manipulated simultaneous release clamping or string. Workover operations in the oil field is used to thread the unloading of a dedicated machinery, in the original XYQ3B hydraulic clamp force on the basis of further refinement from the new products. This product from the oil cycloid torque motor drives, H manual directional control valve and motor oil directly match, compact structure, hydraulic workover rig is the most dynamic clamp a lightweight tubing clamp.   This product has the following characteristics: 1, the first clamp adopted advanced card tight bodies, in the dumping of a diameter of 2 3/8" , 2 7/8" " , 3 ½" two tubing thread, do not replace any parts, cards bear reliable performance, long service life. 2, correspondent for the speed differential, high-grade speed, low-torque large block. 3, the first clamp brake institutions in the clamp on the head cover, adjust, and maintenance is extremely convenient. 4, a new hydraulic clamp back with the main clamp supporting a combination pliers and manipulate the directional valve manually clamp on the back clamp that is synchronized with the main clamp release clamping or synchronized string movements, flexible and reliable. 5, adjustment of supply pressure, can be of various grades of steel tubing required deduction on the best torque.
