Electric Mining Excavator
1.Outstanding Features of the Multifunctional Working Platform
The working platform is capable of 360° horizontal rotation, and its boom adopts a three-section arm design, enabling ±90° rotational operation.
2.Adaptable to Various Types of Tunnel Operations
The height of the arm can be flexibly adjusted according to changes in tunnel size, effectively avoiding contact with anchor bolts, anchor cables and tunnel roofs, and allowing smooth operation in cross-sections of different heights.
The mining hydraulic excavator is capable of conducting excavation, rock loading, bottom cleaning, permafrost digging and other operations in various mines such as coal mines, metal mines and non-metallic mines, as well as in vertical shafts, inclined shafts and horizontal tunnels.
It integrates multiple functions including digging, bottoming, side expanding, lateral excavation, breaking, rock crushing, scraper conveying, belt conveyor bottom cleaning, loading and tunnel leveling, so as to meet diverse operational requirements.
