Feed Beam
Aluminum alloy frame, lightweight, high strength, anti-bending, anti-torsion, anti-fatigue, long service life. Oil cylinder + cable feeding system for smooth movement. Pipe reel combined with joint pipe clamp design increases hose life and reduces maintenance time.
Drilling Boom
Patented double triangular round drilling boom, fully hydraulic automatic balancing control, fast and accurate positioning, large coverage area.
Hydraulic
Plunger type main pump system with clear work division
System
Stable output flow. Pilot type control system for precise action and low hysteresis.
Electrical System
Reliable ABB three-phase asynchronous motor, with phase rotation protection, leakage protection, and overload protection. Suitable for high temperature and humidity environments in underground mines and tunnels. Equipped with an 80m power cable.
Chassis
Articulated chassis equipped with CUMMINS QSB4 engine, DANA 12000 hydraulic transmission, 112 series axles, and SAHR braking system or hydraulic torque converter and transmission, DR20.23E drive axle. Small turning radius, high working speed, good climbing ability.
Water System
Screw air compressor for oil mist lubrication of the rock drill, easy maintenance, function to stop drilling due to pressure loss. Motor-driven booster water pump, working pressure 18 bar, flow rate 84 l/min, can discharge slag during high-speed drilling.
