GR-50 Hydraulic Drill Pipe Breaker (the breaker) is designed to make up and break down tubing, drilling or casing pipes with the diameter of 60-245 mm as well as tighten and loose threaded connections during workover of oil wells with application of high torque.

GR-50 may be equipped with a hand-driven station or a control station operating on the hydraulic station of the workover unit. The breaker may be supplied with the two stations at once.

The equipment can be operated in boreal climate of UHL1 category at ambient air temperatures from minus 45°C to plus 45°C as per GOST 15150 and does not require protection from precipitation.
