The cold-weather drilling rig can normally be operated under a working ambient temperature of -45 degrees, which is suitable for use in the severe cold oil fields in 　　Russia, Canada and other similar regions.
　　The main loading parts of this drilling rig are produced with cryogenic materials which are assessed strictly after low-temperature welding.
　　The travelling block and crown block are produced with special materials and technology processes to ensure good working performance under low temperature conditions.
　　The hydraulic lines, air lines, cables, valves and oils that we selected have a cold weather performance.
　　Electrical heating system or steam heating system is used for the transmission box, oil tank or water tank.
　　Special windproof sheds as well as insulation and heating measures are used for the drilling rig.
