EBZ135L Coal Mine Roadheader
Expert Review
The EBZ series low-profile cantilever roadheaders are widely used in coal mines, highway tunnels, hydraulic culverts, and other engineering projects. Primarily designed for low-clearance operations in moderately hard rock, soft rock, and relatively soft rock formations, they feature a low-profile body, low center of gravity, and stable operation. They offer flexible excavation cross-sections, ensuring safe and efficient performance.
Product Introduction
Adapted for low-clearance tunnels and thin coal seams: Height reduced by 0.3-0.6m compared to conventional models;
Strong coal-rock cutting capability: Compatible with adaptable cutting heads for coal-rock, semi-coal-rock, and solid-rock tunnels;
Wide slope adaptability: Auxiliary traction combined with high-tooth track plates enables ±28° slope tunnel construction;
Excellent adaptability to working conditions: Shovel blades of varying widths and drive configurations accommodate tunnels of diverse widths; telescopic or non-telescopic cutting mechanisms suit coal-rock, semi-coal-rock, and rock conditions.
