20Y hydraulic power tong force in the oil field workover operations on dumping 23/8" ,-3½"drill pipe, and 2 7/8"- 4½" tubing and 4½"-5½" casing of a dynamic open-clamp . It has the following features:
1, the clamp from the torque hydraulic motor driven back by clamp rack plunger drive, drive concise, compact structure.
2, Lord, forceps are used in the dorsal surface of clamping rollers climbing, cards tight, reliable and timely release.
3, the first with the upper and lower clamp Fuzheng outside agencies, rotating stable, long service life.
4, Lord, matching clamp back, reversing valve can be manually manipulated simultaneous release clamping or string.
5, friction braking institutions in the clamp heads of the adjustment, maintenance more convenient.
6, and reset manually reversing valve knob with, for the flexible and convenient.
7, equipped with a retractable security doors installed, the protective effect from security
