D miningwell MW180 small drilling air portable water well drill rig
MW180 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 down-hole impacter with high blast pressure,to realize high effectiveness of drilling footage and low energy consumption.
Advantages of Water Well Drilling Rig:
Engine: adopts the famous brand Guangxi Yuchai 64Kw turbocharged version
Crawler Driving Gear: the designed motor with a speed reduction gearbox prolongs the service life
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.
Rotary head device: integrated casting gearbox , dual motor power, large torque, durable, small maintenance costs
Drill chassis: the professional excavator chassis provides durability and strong load capacity, the wide roller chain plate causes small damage to the concrete pavement
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.
