    1. Detailed information

    Product characteristics::

            KW series water well drilling rig is a kind of high efficient and multi-functional drilling equipment. It is mainly suitable for drilling water wells, agricultural irrigation wells, ground source heat pump wells and other wells, especially for water intake projects in mountainous areas and rock formations. The drilling rig can be used for drilling in different strata, and the maximum drilling diameter can reach 300mm. The drilling rig adopts new hydraulic technology with large torque hydraulic motor rotating and large diameter hydraulic cylinder propulsion. The famous factory engine provides power for the hydraulic system, two-stage air filtration and air intake design with compressed air to extend the service life of the diesel engine. The unique pump group design is convenient for maintenance and reduces maintenance cost. Centrally controlled hydraulic console is easy to operate. This series of drilling rig adopts excavator caterpillar chassis, which has strong cross-country performance. The independent module design enables the rig to be easily mounted on the truck to increase its mobility. The two stall rotation and propulsion speed can meet different penetration requirements in the soil and rock formations. The combined positioner can adjust and replace the positioning plate according to different types of drill pipe and impactor to ensure accurate and reliable positioning. The hoisting mechanism facilitates the hoisting of drill pipes and impactors and reduces labor intensity.
