Our Model KHT5500 hydraulic power tongs is
equivalent to McCoy's KT5500 hydraulic tubing tong. It’s an open power tong which is
applicable to make up or break out 2 3/8"- 3 1/2" drill pipes,
3 1/2"- 4 1/2" tubing and 4 1/2"- 5 1/2" casing during oil field
workover operation. And three-jaw-plate clamping device is adopted in the
master tong and back tongs. The device may ensure minimum string damage.
It has high operation efficiency and may reduce working intensity of the
workers. It can enhance screwing quality of the string and reduce string
accidents caused by improper workover operation.
Characteristics:
1.
The tong head is the open structure which is quick and convenient for entering
and retreating working position. The integral tong head has good hardness and
rigidity;
2.
The three-jaw-plate clamping device is adopted in the master tong and back
tongs. The device may ensure minimum string damage. The front two jaw plates of
the master tong are in the swing structure and the back jaw plate is the
roller-climbing structure. The assembly and disassembly is very convenient. The
optimum tangent-diameter ratio design ensures reliable clamping and easy slope
retreating. The back tong is the three-jaw-plate structure pushed by hydraulic
cylinder. The structure is simple and the clamping is reliable;
3.
Four-gear rotation is adopted for large speed regulation range. And the rated
torque is large;
4.
It has the braking mode with braking staple. The braking torque is large. The
operation is simple. And it is convenient for repair and replacement;
5.
With the open large gear supporting structure, hardness and rigidity of open
large gear is enhanced considerably;
6.
The shell is made of steel plate with high hardness. The overall hardness is
good. Various jaw plates are made with fine casting and forging process. It has
beautiful appearance and high hardness;
7.
Hydraulic torque indicator is provided. And installation interface of turning
torque instrument is provided for computerized management.
