EBZ135 Boom-Type Roadheader
The EBZ135 boom-type roadheader is a lightweight special machine for medium-and-small roadway excavation. Compact in structure, it integrates cutting, material gathering & conveying and crawler traveling functions. Designed for narrow roadways in small and medium-sized mines, it is equipped with a telescopic cutting unit for flexible cross-section adaptation. The modular split structure facilitates transportation and assembly in confined underground spaces. Dual-voltage power supply fits power systems of different mining areas. Balanced efficiency and economy make it a preferred option for roadway construction in small-medium coal mines and non-metal mines.

Telescopic Cutting for Multiple Cross-sections
The cutting head features a 550 mm telescopic stroke. Dual working modes (telescopic / non-telescopic) cover cross-section areas from 6.93 ㎡ to 27.73 ㎡. One unit adapts to various roadway sizes and improves equipment utilization.
Cost-effective Excavation for Medium-hard Rock
It cuts rock with uniaxial compressive strength up to 70 MPa and delivers stable, low-cost performance at 50 MPa, perfectly matching regular mining tasks of coal seams and medium-strength surrounding rock.
Excellent Maneuverability in Narrow Roadways
With a total weight of 38.8 t and body length of 8.92 m plus 2.2 m track width, it achieves a low ground pressure of 0.135 MPa to avoid sinking. The ±18° climbing capacity handles undulating roadways with flexible steering and movement in narrow tunnels.
Convenient Underground Transportation & Assembly
The heaviest single non-detachable component weighs only 5.37 t with compact segmented dimensions. The split structure allows separated lowering into mines and simplifies on-site assembly in space-limited small-medium mines.
Wide Power Supply Compatibility
Dual-voltage input (AC1140 V / 660 V) matches underground power standards worldwide. The matched power combination of a 135 kW cutting motor and a 75 kW oil pump motor ensures balanced power output, lower energy consumption and reduced maintenance costs during continuous operation.
