Features

The feed beam is supported by hydraulic cylinders to ensure the smooth drilling operation; The hydraulic guide cylinders are used to ensure that bores are drilled with near perfect straightness;
The articulated chassis with hydraulic drive system is suitable for small to medium-sized tunnels;
Stepped piston is used in rock drill (drifter), which helps increase drilling speed, improve the efficiency of impact energy transfer from drill to rock, and reduce the consumption of drilling tools while maintaining the condition of the drill rig;
Rod handling system with a capacity of carrying up to 27 drill rods, and drilling depth can reach 42 meters;
The hydraulic longhole 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;
Low-emission Cummins diesel engine paired with hydraulic four-wheel-drive transmission system is included in the hydraulic longhole 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;
Dual-circuit wet multi-disc service brake and multi-pad 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;
The compact structure of the drilling rig makes steering more flexible, the powerful articulated chassis allows for steering angle of ±40° and rear axle swing angle of ±10°, enabling the drilling rig to easily pass through tunnels with a minimum width of 2.5m, and safely achieve right angle turns in a 3m wide tunnel;
The hydraulic longhole drilling rig has a centralized control panel which offers easy operation and gives operator good visibility; In addition, the function of remote control cable control improves the operation safety and maneuverability;
The hydraulic long hole drilling rig adopts a multi-stage oil cylinder direct propulsion system that is standard for the high-power rock drill, ensuring stable thrust during deep drilling.
It’s 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.
This drilling equipment adopts auto-stop device and bottom hole debris clearing function, automatically stopping pushing and impacting after finishing the drilling process.
The hydraulic drilling rig uses Kaishan brand energy-saving integrated direct-connected screw air compressor for smooth operation and easy maintenance.
