Product Introduction
The two-section boom design of Rockbreakers can adjust the height according to the size of the tunnel, preventing collisions with anchor rods, anchor cables and roof rock layers, thus ensuring flexible operation at various cross-sectional heights during the repair work.
The telescopic arm cylinder adopts an internal structure and is equipped with a protective sleeve, effectively protecting the hydraulic cylinder from collision damage during operation.
The compact hydraulic system is characterized by pipes being laid along both sides of the hangers and protected by durable hose covers.
The high-pressure hydraulic system provides the bucket with excellent digging force.
The connection of the hydraulic circuit ensures reliable sealing performance.
The semi-enclosed cab offers excellent visibility and high structural strength, and is equipped with an adjustable height canopy for easy installation and disassembly.
The power unit adopts a centralized and compact configuration, equipped with a protective casing to minimize damage from rock debris, and is also equipped with a forced air cooling system.
Full-range crushing hammer, achieving all-round and no-blind spot crushing, realizing multi-purpose use with one machine.
The electric-hydraulic system operates with low noise and zero exhaust emissions, making it particularly suitable for underground metal mining applications.
