EBZ160 Boom-Type Roadheader
The EBZ160 boom-type roadheader is a medium-size core tunneling equipment with balanced and robust structure, integrating rock cutting, material loading & conveying and crawler traveling functions for conventional roadway construction in medium-scale coal mines and non-metal mines. Equipped with a 550 mm telescopic cutting unit for wide cross-section coverage, it adopts modular split design to realize convenient disassembly, transportation and assembly in confined underground spaces. The dual-gear cutting motor and dual-voltage power supply allow operators to switch power modes according to rock hardness, balancing excavation efficiency, energy consumption and long-term operation stability. It is an ideal machine for regular tunneling in roadways with medium-hard surrounding rock.

Dual-gear Power for Flexible Working Condition Matching
The cutting motor supports two power levels (160 kW / 100 kW) paired with two rotating speeds (48 r/min /24 r/min). High gear enhances rock breaking performance for hard strata, while low gear cuts energy consumption for soft rock, delivering outstanding adaptability to diverse geological conditions.
Telescopic Cutting for Multiple Cross-section Sizes
The 550 mm telescopic stroke of the cutting head covers cross-section areas from 7.9 ㎡ to 25.9 ㎡ with adjustable cutting height and width. One single machine completes roadway forming of multiple specifications and reduces extra equipment investment.
Stable Travel Performance in Complex Underground Terrain
The low ground pressure of 0.14 MPa effectively prevents sinking; ±18° climbing capacity adapts to undulating roadways. The 2.33 m wide crawler and 2.9 m wide shovel plate collect and convey fallen materials efficiently to avoid material accumulation.
Low Construction Threshold via Split Transportation
The heaviest single non-detachable component weighs only 5.1 tons with compact segmented dimensions. The split structure can be transported underground separately, simplifying delivery and on-site assembly in narrow roadways of small-and-medium mines.
Global Power Supply Compatibility
Dual-voltage input (AC1140 V / 660 V) conforms to underground power standards across the world. The 90 kW oil pump motor matches the dual-gear cutting motor perfectly for stable continuous operation and controllable maintenance costs.
