High power RNP rock drill, high efficiency and energy saving, low noise. Equipped with high-power RNP rock drill, high efficiency and energy saving, low noise. The rotary motor is bidirectionally reversible and has stepless speed regulation, which can provide powerful torque required for efficient operation; the advanced double buffer system protects the rock drill and drilling tool; The combined action of the oil inlet, buffer and oil return accumulators ensures the smooth operation of the rock drill, thruster, drill arm and hydraulic system, improves production efficiency, and reduces failure rate and maintenance workload.
The heavy-duty drill boom supported by double triangular suspension can ensure the parallel maintenance of hvdraulic pressure in all directions. The drill boom adopts a single handle direct positioning method, which is fast and accurate. The cold-drawn double bottom structure aluminum alloy propelling beam has high bending and torsional strength and long service life. The surface of the propelling beam is covered with stainless steel skin, and the moving parts are made of PTFE wear-resistant liners to adjust the wear gap and keep the driling jumbo centered simply and conveniently.
The drilling jumbo and drilling system have protection functions such as automatic control propulsion by rotary pressure, automatic control of impact by propulsion pressure, and automatic drill rod jam prevention.
Equipped with a sturdy articulated heavy-duty chassis, four-wheel drive. The rear axle oscillating device ensures good contact with the ground in harsh conditions.
