HQZ series water well drilling rig is a lightweight, efficient, and multifunctional drilling equipment. It is mainly suitable for industrial and civil drilling, geothermal drilling, with the advantages of compact structure, fast footage, flexible movement, and wide applicability, especially suitable for water extraction in mountainous and rocky areas.
This drilling rig can perform drilling operations in different formations, using new hydraulic technology, supporting large torque hydraulic motor rotation and large-diameter hydraulic cylinder propulsion. A well-known multi-cylinder engine provides power to the hydraulic system, and a two-stage air filter and air compressor intake design extend the life of the diesel engine. The unique pump group design is convenient for maintenance, reducing maintenance costs. The centrally controlled hydraulic console is easy to operate.
This series of drilling rigs adopts an excavator crawler chassis with strong off-road performance. The independent modular design allows the drilling rig to be mounted on a truck, increasing its maneuverability. Two-speed rotation and propulsion speeds can meet different drilling needs in soil and rock formations. The combination locator allows adjustment and replacement of positioning discs according to different models of drill rods and impactors, ensuring accurate and reliable positioning. The hoisting mechanism facilitates the lifting of drill rods and impactors, reducing labor intensity.
