EBZ180 Boom-Type Roadheader
The EBZ180 boom-type roadheader is a medium-heavy main tunneling machine with solid structural rigidity and abundant power. It integrates rock cutting, muck loading and crawler transportation, specially engineered for medium-hard strata in medium-to-large coal mines and metal mines for medium-large cross-section tunneling. It cuts rock up to 80 MPa compressive strength and achieves cost-effective operation at 60 MPa. The modular split design facilitates underground segmented delivery and assembly, while the high-power hydraulic system supports long-shift continuous operation for regular tunneling in harder surrounding rock. Outperforming medium-duty models, it can be replaced by our heavy-duty series for extra-large sections or extremely hard rock conditions.

High-power Rock Breaking for Hard-stratum Adaptability
The 180 kW cutting motor runs steadily at 47.4 r/min to break rock with uniaxial compressive strength up to 80 MPa. It maintains high efficiency and controllable energy consumption at 60 MPa, resisting jamming in hard-rock working conditions with stronger penetration than ordinary medium-duty roadheaders.
Flexible Roadway Forming with Wide Cross-section Coverage
The available cutting area ranges from 8.5 ㎡ to 22 ㎡, with adjustable cutting height (2.5–4.4 m) and width (3.4–5.0 m). One unit constructs multiple mainstream roadway sizes and reduces model replacement frequency on site.
Stable Mobility in Complex Underground Terrain
Weighing 56 t with 2.4 m wide tracks, the machine features 0.19 MPa ground pressure to balance load capacity and anti-sinking performance. ±18° climbing capacity copes with undulating tunnels. The 3.0 m wide shovel plate with 400 mm sumping depth collects low-position muck thoroughly for smooth discharge.
Convenient Split Transportation Underground
The heaviest single non-detachable component is only 4.42 tons. Three compact segmented assemblies pass narrow underground passages easily for low-difficulty on-site assembly to match most mine logistics conditions.
Reliable Power Matching & Mine-oriented Power Supply
The 110 kW oil pump motor coordinates perfectly with the 180 kW cutting motor for stable hydraulic output. The AC1140 V power specification conforms to mainstream domestic coal mine power standards, delivering low failure rates and easy maintenance during long continuous shifts
