The surface DTH drilling rig is equipped with a Yuchai four-cylinder diesel engine and an integrated controller for real-time monitoring of drilling parameters. The rig adopts a reinforced folded crawler frame and heavy-duty undercarriage, with track leveling and a plunger-type feed motor to increase working pressure and improve climbing performance.

• The slide wear strips are made of wear-resistant materials to extend the service life of the feed beam
• The dual-motor rotary head, with a large reduction ratio, delivers a maximum rotary torque of over 4000 N·m. At the same time, the feed motor is paired with a 24A roller chain, significantly improving drilling reliability
• The hydraulic system is upgraded with high-pressure, large-displacement cast iron gear pumps, ensuring high reliability, long service life, and stable performance
• Frame components are optimally arranged to significantly increase internal space. The housing features reinforced structural materials with multi-side access doors, making maintenance and servicing easier
