Core Advantages of Our Rock Drilling Jumbo
- Secondary Keywords: Underground Rock Drilling Jumbo, Tunnel Drilling Jumbo, Mining Drilling Jumbo
– High Drilling Efficiency & Strong Adaptability: Equipped with imported high-power drilling hammers and optimized hydraulic transmission system, the rock drilling jumbo achieves fast drilling speed and stable hole forming. It adapts to hard rock, medium-hard rock and complex geological layers, with a maximum drilling depth of 6m and a drilling diameter range of 28mm-76mm, meeting diverse construction standards.
– Intelligent & Safe Operation: Adopts humanized cab design with shock absorption and dustproof functions, effectively improving operator comfort. Equipped with automatic positioning, anti-collision protection and emergency stop systems, the underground drilling jumbo minimizes construction safety hazards and realizes standardized, intelligent drilling operation.
– Durable & Low Maintenance Cost: The whole machine adopts high-strength steel structure and wear-resistant accessories, resisting impact and corrosion in harsh underground environments. The modular assembly design simplifies daily maintenance and parts replacement, greatly reducing later operation and maintenance costs and extending equipment service life.
– Energy-Saving & Environmentally Friendly: Optimized power matching system reduces fuel and power consumption by 15%- compared with traditional drilling jumbos. Equipped with professional dust removal devices, it effectively controls construction dust, complies with global environmental protection standards for mining and tunnel construction.
– Flexible & Wide Application: Multiple boom configurations (single/double/triple boom) are optional. The compact body structure is suitable for narrow mine roadways and small-section tunnels, while the high-power model meets the high-intensity drilling demands of large-scale tunnel projects, with strong construction flexibility.
