Narrow vein drill rig

• Medium/low pressure hydraulic drifters from Montabert are used in the hydraulic tunneling drilling rig. Since hydraulic hoses and seals do not work in high pressure environments because the hydraulic drifter operates at low oil pressure, 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;
• 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;
• Wet multi-disc service brake and spring-applied hydraulically released parking brake provide safe braking and high stability; In addition, emergency stop buttons at multiple points significantly enhance the safety during underground mining and tunneling operations;
• Low-emission Cummins diesel engine paired with hydraulic four-wheel-drive transmission system is included in the hydraulic tunneling drilling rig, achieving stepless speed adjustment, high gradeability and fast walking speed; The exhaust purification device is equipped to greatly improve the underground working environment;
• The spacious operating environment, lifting protective roof and considerably designed automatic functions of the narrow vein 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;
• The compact structure of the tunneling jumbo makes steering more flexible, the powerful articulated chassis allows for steering angle of ±35° and rear axle swing angle of ±6°, enabling the drilling rig for drilling operations in tunnels with cross sections ranging from 2.2m×2.2m to 5m×4.3m, it can pass through a cross section of up to 2m×2m;
