Underground Mining Equipment
Hydraulic Drilling Jumbo, HT72(for Mining)
Our HT72 hydraulic drilling jumbo is engineered for high-performance medium- to deep-hole drilling and it is particularly effective in fan-shaped and cluster hole operations. This hydraulic drilling jumbo excels in small cross-section tunnels, offering exceptional maneuverability even in narrow underground environments.
Equipped with a versatile articulated boom that integrates swing and translational motion, the hydraulic drilling jumbo achieves full 180° horizontal and vertical coverage. This allows the jumbo to drill across wide areas from a single position, ideal for complex, multi-angle blast hole drilling.
Designed with operator safety in mind, the hydraulic drilling jumbo features a reinforced canopy to protect against falling rocks, delivering comprehensive on-site protection. It ensures that your crew stays safe while maintaining peak efficiency in demanding mining operations. Transform the way you drill with a solution that expands your reach, protects your team, and keeps your operation moving with precision.
Details
