Product Introduction
The two-section boom design can adjust its height according to the road surface size to prevent collisions with anchor rods, anchor cables and roof rock layers. This ensures that during maintenance operations, flexible work can be carried out in tunnels of different cross-sectional heights.
The telescopic arm cylinder adopts an internal protective sleeve design, effectively protecting the hydraulic cylinder from impact damage during operation.
The compact hydraulic system includes pipes arranged along both sides of the boom and is protected by durable hose covers with protective sleeves.
The high-pressure hydraulic system provides outstanding bucket digging force.
The design of the hydraulic circuit connection ensures reliable sealing performance.
The semi-enclosed cab combines an excellent field of vision with a high-strength structure. Its canopy height is adjustable and it is easy to install and remove.
The power unit adopts a centralized compact structure and is installed inside the protective cover. This minimizes the damage caused by rock debris and is equipped with an efficient forced air cooling system.
The full-range breaker hammer achieves all-round crushing without blind spots, expanding the multi-functionality of the machine and making it suitable for a variety of applications.
The electric-hydraulic system operates with low noise and zero exhaust emissions, making it particularly suitable for underground metal mining environments.
