Mobile workshop with Bench-top wrench KG-12

Client “New Tech Services”, 2016


Mobile workshop is equipped with facilities that are necessary for the servicing of gaz and oil pipe connections requiring the use of a high torque. A special project of insulation and a highly effective and economical heating system at the workshop allows the comfortable operation at temperatures up to - 50º C. According to the Client’s request the workshop may be equipped with any hydraulic wrench or other accessory equipment. Overall dimensions of the workshop do not require any additional permission for transportation.
Workshop’s assembly and disassembly take not more than one work shift.

Bucking Unit KG-18

In 2010 special equipment was needed by JSC TATNEFT for the handling of the drill string in rig environment. Our company offered a mobile bucking unit KG-18. We designed and manufactured the wrench a year after, and in winter 2012 we performed a supervised installation of the unit. Nowadays the unit is successfully operated year-round by JSC TATNEFT.


The bucking unit is designed so that all the make up and break out operations with the use of a high torque may be performed year-round at the temperatures up to -20˚C.
