Hydraulic Power Tong GKSh-4000GZ


Hydraulic Power Tong GKSh-4000GZ is designed to handle a range of casing sizes from Ø102 mm (4") up to Ø508 mm (20").

Hydraulic backup is with a range of pipe coverage from Ø102 mm (4") up to Ø451 mm (17 3/4").

Manufactured for operation in areas with moderately cold climate, category 1 as per GOST 15150-69 (-45 to 50 °C).

Ufagidromash production meet the needs of the oil and gas industry with innovation, performance, and value. In particular, Hydraulic backup based on a unique development of Ufagidromash LLC has a number of innovative solutions:

  • the pipe is gripped with three jaws, that distribute gripping forces over a greater area without damaging the casing;
  • jaws with an extended range are used, which allows by one set of jaws to grip the pipe body, the pipe coupling, the casing shoe, the cementing check valve;
  •  the simplicity of the design allows you to quickly replace the jaws for different range of pipe diameters;
  • there is no need to reinstall the jaws into the position of making up and breaking out of the string;
  • special attention is paid to the joint of the Hydraulic backup with the main tong body. The two-point attachment equidistant from the center of the pipe with a balancing torsion eliminates the appearance of radial bending forces on the thread. This arrangement allows pipes to be made up with "pure" torque without additional friction in the threaded joint.
