D miningwell well drilling rig 200meters small water drilling rig
Crawler water well drilling rig MW200 is suitable for industrial and civil drilling and geothermal drilling. It has the advantages of large drilling diameter, deep drilling depth, fast footage, and flexibility.
MW200 multifunctional crawler well drill is a new,highly-effective ,energy-saving and multifunctional hydraulic drill and it is specialized in drilling well ,monitoring well, geothermal air-conditioning hole,grouting hole of the hydropower cofferdam,grouting hole for dyke seepage control and grouting hole for base enforcement ,surface mining ,anchorage .national defense project and other drilling operations;The drill rig is equipped with hydraulic motor rotation with a high power,propulsion and lifting of cylinder and dth hammer with high blast pressure,to realize high effectiveness of drilling footage and low energy consumption.
Advantages of water well drilling rig:
1. Engine: adopts the famous brand Yuchai 65Kw 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
8. 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.
