Product Description

KHT5500 new hydraulic power tong

Description:

KHT5500 hydraulic power tongs is the open power tongs which is applicable to make up or break out 23/8"-31/2" drill pipes, 31/2"-4+/2" tubing and 41/2"-51/2" casing during oil field workover operation. And three-jaw-plate clamping device is adopted in the master tong and back tongs.

KHT series Casing Power Tong is used to make up and break out for casing operation in oil fields. It has greatly reduced the labor of worker, enhanced connection quality of thread and diminished accidents inappropriate casing operation. The power tong has the following features as well:

Opening type, convenient and prompt to enter and slide off the working position, with an integral tong
head of great strength and rigidity. Double swing head jaws, convenient to assemble and disassemble. Brake belt assembly, easy to operate and convenient to maintain and replace. Open gear supporting structure, improving the strength and rigidity. Wholly hydraulic mode and mechanical gear shift. High strength steel plate used on the shell,increasing the strength. The jaws are cast with precise technology, artistic and strong. With hydraulic torque indicator and also installation interface, convenient to realize the computer management. Use safety door hydraulic safety device,of great safety performance. Large torque range,can meet the requirement of larger torque use.

Features
1. 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;
2. Four-gear rotation is adopted for large speed regulation range. And the rated torque is large;
3. 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;
4. With the open large gear supporting structure, hardness and rigidity of open large gear is enhanced considerably;
5. 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;
6. Hydraulic torque indicator is provided. And installation interface of turning torque instrument is provided for computerized management.
