D miningwell 450m borewell drilling rigs
MW450 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.
MW450 type water well drilling rig is a light weight, efficient and multifunctional drilling equipment, it is mainly applicable to industrial and civil drilling, geothermal drilling, has the advantages of compact structure, fast advancing, mobile and flexible wide application region etc., It is especially suitable for water intake in mountainous and rocky strata.
The rig can create drilling jobs in different strata, borehole diameter can up to 140-358mm. The rig with hydraulic technology, supporting high torque hydraulic motor rotation and large bore hydraulic cylinder push, the multi cylinder engine of famous factory provides power for the hydraulic system, two stage air filter, air compressor intake design, prolong the service life of diesel engine. Special pump set design is convenient for maintenance and reduce the cost of maintenance. Centralized control of the hydraulic control table, convenient operation.
This series of drill rig adopts a excavator crawler chassis and has strong off-road performance. The independent module design allows the drill to be mounted on the truck to increase its mobility. Two speeds of rotating and advancing speed can meet the different needs of soil and rock drilling. Combined positioner, the positioning disc can be adjusted and replaced according to different types of drill pipe and DTH hammer, so as to ensure the accuracy and reliability of the positioning and centering. The hoisting mechanism is convenient for hoisting of drill pipe and DTH hammer, so as to reduce the labor intensity.
