Features
  • Independently designed drilling rig boom uses Cartesian coordinate action principle to enable quick and simple drilling positioning since it can achieve that the feed beam is automatically parallel to the origin position; The robust drill boom offers optimum shaped coverage, with no blind spot for drilling holes, the boom can also execute cross-cut drilling and bolt hole drilling operations;
  • The hydraulic tunneling drilling rig is configured with medium/low pressure hydraulic drifters from Montabert. Hydraulic hoses and seals do not operate in high pressure conditions since the hydraulic drifter works under low oil pressure, thus resulting in prolonged service life, high reliability and less maintenance cost when compared to high pressure hydraulic drifter;
  • The rock drill (drifter) uses stepped piston, which improves the efficiency of impact energy transfer from drill to rock, increases drilling speed, lowers the consumption of drilling tools while keeping the drill rig in good condition;
  • Low-emission Cummins diesel engine is included in the hydraulic tunneling drilling rig, achieving stepless speed adjustment; The crawler chassis ensures high gradeability;
  • The exhaust purification device is equipped to greatly improve the underground working environment;
  • The hydraulic tunneling drilling rig uses dual-circuit wet multi-disc service brake and emergency stop buttons at multiple points, greatly improving the safety during underground mining and tunneling operations;
  • The spacious operating environment, lifting protective roof and considerably designed automatic functions of the face drill rig allow the operator to focus on drilling safely, quickly and accurately;
  • Optimal layout of the drilling rig enables operator has a good visibility, and all parts at service points are securely protected, and accessible for easy maintenance;
  • KJ310 hydraulic tunneling drilling rig is equipped with the original power control valve block from Montabert, France, enabling it to feature automatic impact pressure adjustment, and anti-jamming function. This ensures smooth and accurate hole drilling during the operation.
  • It adopts auto-stop device and bottom hole debris clearing function, automatically stopping pushing and impacting after finishing the drilling process. The handle control can be used to blow out residue and water at the bottom of the hole, eliminating the need of manual cleaning and reducing operation cycle time.
  • The drilling equipment uses Kaishan brand energy-saving integrated direct-connected screw air compressor, offering smooth operation, easy maintenance, significantly saved energy and reduced pollution.
