D miningwell 300m dth borehole drill deep small machine down the hole water well drilling rig
MW300 is a high efficiency and multi-functional down the hole water well drilling equipment, It can be used to drill water well, agricultural irrigation well, geothermal well and other type well holes. It is special suitable for mountain area and rock stratum water sourcing project.
This machine adopts big torque hydraulic motor for power head and brand diesel, big diameter hydraulic
cylinders for the hydraulic control system. The brand diesel is protected by 2 levels air filtration systems and also can directly use the clean air from the air compressor.
Advantages of MW300:
1. Engine: adopts the famous brand Guangxi Yuchai 85Kw turbocharged version
2. Crawler Driving Gear: the designed motor with a speed reduction gearbox prolongs the service life
3. Hydraulic Oil Pump: It uses parallel gearbox (which is a patent) to separate oil pump monomer, supply adequate power and distribute reasonable. The hydraulic system adopts unique design, which is easy to maintain and can lower the maintenance cost.
4. Rotary Head Device: integrated casting gearbox , dual motor power, large torque, durable, small maintenance costs
5. Drill Chassis: the professional excavator chassis provides durability and strong load capacity, the wide roller chain plate causes small damage to the concrete pavement
15. Lifting Force: patent designed composite arm with small size yet long stroke, double cylinder lifting, strong lifting capacity. The lift arm is installed with a limiter to protect cylinder and ensure the safety of work. Each hydraulic tubing is covered with a protective shell to effectively extend the service life of pipeline.
