Ebh 340 Large Cross Section Hard Rock Roadheader - China

The Weishi EBH340 heavy-duty roadheader machine, as Weishi Heavy Industry's flagship horizontal axis hard rock tunneling equipment, is specifically designed for tackling challenging conditions in deep wells with large cross-sections and high-density, ultra-hard rock tunnels.

It directly addresses industry pain points such as high wear and tear on cutting tools, severe machine vibration, and poor tunnel formation.

The machine features a 140-ton heavy-duty frame paired with a powerful 540kW power system and a patented horizontal axis cutting head, capable of conquering hard rock strata with compressive strength ≤130MPa, achieving a maximum cutting area of 45㎡, truly realizing one-time formation of large-section tunnels.

It is the ultimate solution for tunneling large-section tunnels in hard rock.

Maximum rock strength: ≤130 MPa

Maximum cutting area: 45 m²

Cutting motor power: 340 kW

Total installed power: 540 kW

Machine weight: 140 t Key Product Highlights:

340 kW Transverse Cutting System: The EBH340 uses a low-speed, high-torque transverse cutting head driven by a 340 kW cutting motor.

140 t Heavy-Duty Stable Chassis: Machine stability is critical when cutting strong rock.

The EBH340 combines a 140 t machine weight with a wide crawler base and a low center of gravity.

The entire frame is made of Q460 high-strength alloy steel, and the low center of gravity and wide body design ensure excellent stability during hard rock cutting, effectively preventing tool skipping and excessive vibration.

A uniquely patented horizontal axis cutting head design, equipped with 186 high-strength alloy tooth holders.

The scientifically designed tooth distribution improves rock-breaking efficiency by 35% compared to traditional models and increases wear resistance by 50%.

Combined with an anti-detachment tooth holder design, it significantly reduces the frequency of tooth replacement underground.

High-Capacity Loading and Conveying: The EBH340 is equipped with a four-claw star-wheel loading system rated at up to 400 m³/h.

The double-chain scraper conveyor provides a rated conveying capacity of up to 480 m³/h.

A 45㎡ tunnel can be formed in one go, eliminating the need for segmented widening and trimming processes.

This allows for efficient excavation of ultra-large cross-sections, significantly increasing monthly tunneling capacity.

Intelligent Control and Fault Diagnosis: The electrical system utilizes a top-tier international configuration: an imported Finnish EPEC controller and a German Moeller main switch.

The IP67-protected control box easily handles the humid and dusty underground environment.

A 23-category fault self-diagnostic engine monitors equipment status in real time.

Reserved RS485/CAN/Ethernet multi-protocol IoT interfaces support remote monitoring via mobile APP and allow for rapid upgrades to an intelligent tunneling system.

Dust Suppression and Equipment Protection: The EBH340 provides an internal spray pressure of at least 2 MPa and an external spray pressure of at least 4 MPa.

Optional cutterhead shielding can provide additional protection against dust and flying rock in highly abrasive working conditions.

With 7 customization options, one machine can meet the needs of all deep hard rock development roadway excavation in a mine.
