This drilling rig can be used for perforation on different stratums. It adopts the new hydraulic technology as well as large-torque hydraulic motor for revolving and large-diameter hydraulic oil cylinder for propelling, famous-brand multi-cylinder engine that provides power for the hydraulic system, two-step air filter and air compressor for air intake to extend the service life of the diesel engine. The unique pump unit design is convenient to maintain, which reduces the maintenance cost. The hydraulic console that is controlled in a centralized way can be operated conveniently.

Equipped with an excavator crawler chassis, this series of drilling rig is of strong off-road performance. With the independent modular design, the drilling rig can be installed onto the truck to improve the maneuverability. Two-gear revolving and propelling speed can meet different perforation demands on the soil layer and the rock layer. The positioning plate of the combined positioner can be adjusted based on the model of the drill pipe and the impactor to ensure the accuracy and reliability of the positioning and centering. The hoisting mechanism facilitates hanging of the drill pipe and the impactor to reduce the labor intensity.
