Interchangeable Closed-head Tong is same with 58-93R Closed-Head power tong，it
is a safe and accurate unit for the makeup and breakout of tubing and casing
1-5/16" O.D. through 7"O.D. It is a kind of special machine used to
makeup the tubing thread in oilfield workover operation, it is a heavy duty
workover power tong which applies to max.7”casing, the max. torque is over 8
kN.m, it can applies to all kinds of complicated work operation work.
This power tong
has features below:
-
Closed head design, which can better ensure the alignment of the tube and more accuracy of the alignment.
-
Two speed operation which have a big differential，fast speed in high gear，big torque in low gear, and torque can be controlled；
-
With lubricating device which can ensure the sufficient lubrication of the moving parts and absolute seal.
-
Roller chain drive is adapted in the tail end.
-
Using adjustable friction clutch can not parking shift, not only improve the service life of transmission parts, but also has the ability of overload protection.
-
Pliers drive motor, hydraulic control valves and back-ups reversing valve adopts imported assembly.
-
High strength safety torque arm.
-
The back-up tong adopts cylinder clamping which can reduce the damage the pipe.
-
Can equipped with hydraulic spring lift bucket, satisfy any operation position.
