The Low Temperature Truck Mounted Drilling Rig YJ350 is a special cold climate truck integrated mobile drilling rig, designed and manufactured per API 4F, API 7K and ISO9001 standards.
The Low Temperature Truck Mounted Drilling Rig YJ350 is a special cold climate truck integrated mobile drilling rig, designed and manufactured per API 4F, API 7K and ISO9001 standards. This unit is purpose built for oil & gas, geothermal and water well drilling operations under extreme frigid environments, applicable for well depths up to 3500 m. All core drilling assemblies including derrick, drawworks, rotary table and power pack are installed on an all terrain heavy duty truck chassis. The complete machine realizes self propelled road travel without tractor vehicle, and adopts full system low temperature thermal insulation, anti freezing and cold start modification. It can reliably perform rig up, drilling and rig down under severe sub zero ambient conditions. It is widely used for energy exploration and workover projects in alpine, high latitude and seasonal frozen soil regions, serving as a reliable self propelled drilling solution for cold area scattered well group development.
Main drilling assemblies are compactly integrated on high mobility off road truck chassis. The rig realizes self driving transfer without additional towing equipment, with good cross country performance to adapt to unpaved winter access roads in cold zones. Main components remain assembled during transit, greatly shortening transition cycle between well locations.
Fuel circuit, hydraulic system, lubrication circuit, water medium pipeline and instrument cabin are equipped with heating modules and thermal insulation layers. Special low temperature hydraulic oil, lubricants and sealing elements are adopted. Supporting electric preheating and engine auxiliary cold start device ensures normal startup and continuous operation under extremely low temperature conditions.
High strength alloy derrick with full hydraulic erecting / laying down mechanism. No large field crane is required for well site deployment. Key structural welds and stress bearing parts adopt low temperature impact resistant material to prevent brittle fracture in frigid climate.
Heavy duty telescopic hydraulic outriggers with synchronous leveling function. The rig can finish quick leveling and stable supporting on frozen ground without complicated concrete foundation. Outrigger cylinder components use cold resistant seals to avoid leakage under low temperature working conditions.
Control cabinet, sensor components and cable assemblies adopt low temperature grade components with anti condensation heating function. The whole control logic is optimized for cold site field operation; key wearing parts adopt universal specifications to facilitate spare part supply in remote alpine project areas.

The YJ350 low temperature drilling rig answers a question most rigs never face: can it start, run and keep drilling at -45°C? Rated to 3500 m with a 2000 kN hook load and a 630 kW (845 HP) drawworks, this truck-mounted unit wraps the derrick, drawworks, rotary table and power pack into one all-terrain self-propelled chassis, so it travels at up to 75 km/h under its own power — no tractor, no convoy planning. The mechanical-hydraulic compound drive is deliberately simpler than a full AC VFD system, because in a Siberian or northern-Canada winter, the fewer electronic boxes in the cold, the fewer cold-start failures.
When you request a YJ350 quotation for a cold-region project, the decision parameters are different: tell us the lowest expected sustained temperature, the length of the operating season, and whether the site has grid power or must run on the onboard engine. The -45°C rated package covers insulation, anti-freeze circuits and cold-start modification across all systems; standpipe pressure up to 35 MPa and a 10-line hoisting arrangement on 29 mm wireline handle the medium-depth workover and drilling mix this class is normally asked to do.
YJ350 pricing follows the cold-package options you select — winterisation grade, tyre configuration and engine heat management all move the figure. Expect a configuration-based quotation within two working days of your site climate data and well list.
Upgrade heating power grade, change to lower temperature rank sealing materials; add anti snow accumulation protective covers for instruments and rotary components for ultra cold winter conditions.
Adjust chassis off road configuration, tire specification and auxiliary braking system to adapt to ice snow road and mountain cold zone transportation requirements of different countries.
Optimize engine cold calibration parameters; support auxiliary electric power module configuration for reducing fuel consumption during standby heating in long time low temperature environment.
Reserve interfaces for drilling parameter acquisition, pipeline temperature monitoring, fault alarm and auxiliary pipe handling attachments for digital cold region drilling management.
Custom painting, customer brand logo marking, cold zone specific spare parts package and full cycle after sales technical support are available.
