This drilling rig can perform drilling work on different geological formations, with a drilling diameter of up to 245-294mm. The rig adopts a new hydraulic technology, matched with a high torque hydraulic motor for rotation and a large cylinder diameter hydraulic cylinder for propulsion. The multi cylinder engine from a well-known factory provides power for the hydraulic system, and the two-stage air filter and air compressor intake design extend the service life of the diesel engine. The unique pump design facilitates maintenance and reduces maintenance costs. Centralized hydraulic control panel for easy operation.
This series of drilling rigs adopts excavator track chassis with strong off-road performance. The independent module design allows the drilling rig to be mounted on a truck, increasing its maneuverability. Two speed rotation and propulsion can meet the different drilling needs in soil and rock layers. The combined locator can adjust and replace the positioning disc according to different models of drill rods and impactors, ensuring accurate and reliable positioning and centering. The hoisting mechanism facilitates the lifting of drill rods and impactors, reducing labor intensity.
This machine is suitable for various geological formations, such as water well engineering, geothermal wells, anchor pile holes, etc., and can also be used with drilling tools. It has the advantages of complete hydraulic control, automatic drilling rod loading and unloading, tracked chassis, high horsepower diesel engine, four corner hydraulic balance, and stronger terrain adaptability.
