12YA hydraulic clamp 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
