Hydraulic Power Tong GKSh-4200

Description

Hydraulic Power Tong GKSh-4200 is designed to handle a range of drill pipe sizes from Ø60 mm (2 3/8") up to Ø178 mm (7").
Designed for moderately cold climate with ambient temperatures -45 to +50 C.


Features

This tong is the next step in the development of the GKSH-3200 model. To ensure the tongs higher torque performance, the following features have been upgraded: a hydraulic backup, a manual gearbox and gears.
A two-sectional hydraulic motor and a manual gearbox allow you to get four different torque ranges at the same pressure of the working fluid from 0 to 200 bar.
The set of jaws for the Hydraulic backup has a wide range of pipe coverage.
