EBZ200A Coal Mine Roadheader
Expert Evaluation
The EBZ series conventional boom roadheaders are extensively employed in coal mines, road tunnels, hydraulic culverts and similar projects. Primarily designed for medium-hard rock formations, soft rock and relatively friable strata, they enable single-pass or layered excavation with flexible cutting faces, delivering safe and efficient performance.
Product Overview
Exceptional coal and rock cutting capability: Adaptable cutting heads for diverse formations including coal-rock, semi-coal-rock, and solid rock tunnels
Wide Gradient Adaptability: Auxiliary traction combined with high-tooth track plates enables construction in tunnels with gradients up to ±28°.
Excellent Adaptability to Working Conditions: Shovel blades of varying widths and drive configurations suit tunnels of diverse widths; telescopic or non-telescopic cutting mechanisms are selected to accommodate coal-rock, semi-coal-rock, and rock conditions.
