SNR1200 Water well drilling rig

The SNR1200 fully hydraulic crawler mounted water well drilling rig is suitable for big drilling projects with a maximum drilling depth of 1200m and a drilling diameter range of 105-900mm. The main shaft pressure is 13t and the lifting force is 61t. The SNR1200 is compatible with 127mm drill rod. And the maximum rotary torque is 31000/15500 N.m. Weight of the rig is 26 tons and the dimension is 11.8*2.25*3m.

Main Features

• The key hydraulic components of the SNR1200 waterdrilling rig are all imported brand accessories, which significantly reduces its failure rate and extends the working life of the rig, while also reducing the overall weight of the machine. And the lifting capacity can reach up to 60tons, with a maximum drilling diameter of 12
• Equipped with water vapor dual-purpose rotary head, whichcan use air DTH hammer drilling and mud drilling;
• Rotation, drilling, and lifting of the drilling rig are all controlled by hydraulic dual speed adjustment, which makes thedrilling parameters more reasonably matched with the drilling conditions.
• The hydraulic system is equipped with an independent air-cooled hydraulic oil radiator, and a water-cooled radiator can beoptionally installed according to user requirements to ensure efficient and continuous operation of the drilling rig hydraulic
• system under high temperature climate conditions in different regions.
• Equipped with the BW1200 mud pump, the large displacement guarantees effective cuttings transport and high penetration rates, whereas the high pressure enables overcoming circulation resistance in deep holes and sustaining stable fluid return, thereby realizing efficient, safe, and low-cost drilling for 1000-meter water wells.
• The auxiliary actions such as loading and unloading drill rods, leveling the drilling rig, and hoisting are allcontrolled by a hydraulic system. The rig features a reasonable structural layout, making it easy to operate and
• Equipped withCummins engine which ensure the stability of drilling rig in working condition;
• Thefully hydraulic dual rotary head can be optional. using a down the hole impact hammer，mud drilling or drilling with casing to meet different geological conditions for drilling operations. Suitable for projects such as large-diameter water wells, pile holes, and mine rescue.
• Adapted professional Komatsu excavator crawler base
• Equipped with the American Eaton brand hydraulic rotary motor, the rig benefits from its low-speed stability, high-pressure high-torque output, and field-proven reliability, enabling continuous, smooth, and efficient rotary drilling in 1200 meter deep wells and complex formations. Additionally, the flexible integration design streamlines system configuration and minimizes overall equipment failure rates
