crawler hydraulic core drilling rig for mineral survey

crawler hydraulic core drilling rig

the crawler hydraulic core drilling rig is a device specially developed for geological drilling and mineral sampling. it combines hydraulic power with a crawler traveling system, which not only improves operational efficiency but also enhances the machine’s adaptability to complex terrains.

features of the crawler hydraulic core drilling rig

• all hydraulic components use premium brands to ensure stable overall performance.
• the power head features a chuck design, supports lateral movement and dual-speed mechanical shifting, and provides precise speed control.
• the feed system adopts a direct cylinder-driven structure to increase drilling speed.
• the mast is controlled by hydraulic cylinders for lifting, can be folded for easier transport and storage, and is equipped with a ground-sliding function.
• the load-sensitive hydraulic system and dual-motor closed circuit for power head rotation offer strong power and higher efficiency.
• the mast is equipped with upper and lower centering devices for inclined hole operation, and the orifice has a hydraulic holder for more accurate drilling.
• a double-layer working platform provides a more spacious operation area.
• crawler, platform, or truck-mounted types are available to meet various user requirements.

working principle of the crawler hydraulic core drilling rig

this rig efficiently distributes engine power to the power head, feed device, and mast through the hydraulic system, enabling drilling, feeding, and lifting actions. the rotating power head drives the drill rod and bit to cut through the strata, while the feed mechanism pushes the drill rod deeper. the crawler chassis ensures the equipment can move and remain stable on rugged terrain. load-sensitive control allows the hydraulic system to intelligently adjust output according to actual working conditions, improving energy efficiency and operator comfort.

applications

widely used in geological exploration, mineral resource assessment, hydrogeological surveys, coal and oil drilling, and capable of performing core drilling in mountains, hills, forests, and other complex environments.
