Roadheader Series Overview

Overall Performance
The roadheader series features a heavy-duty frame, low center of gravity, and a well-balanced structural layout. The machines deliver stable and reliable performance, making them ideal for the excavation of coal and semi-coal rock.

Application Range
Suitable for roadway sections 4 to 6.5 meters wide and 3 to 5.1 meters high, and for rock formations with a hardness rating of F9 or lower.

System Features

Water System
Equipped with a dual-stage high-precision filtration system to ensure clean water supply. Advanced internal and external spray technologies provide reliable dust suppression and cooling.

Electrical System
With IP67 protection and explosion-proof components, the electrical system ensures safe and reliable operation even in harsh environments. Intelligent monitoring, fault diagnosis, and real-time alarms support remote supervision. Equipped with electrical components from globally recognized brands, the system includes comprehensive automatic protection functions for high operational stability. Remote control capability enables easier operation, reduces worker exposure to dust and hazards, and improves safety while lowering labor intensity. Intelligent cutting functions allow for autonomous cutting window optimization and remote unmanned operation, adding a layer of safety to tunneling operations.

Hydraulic System
The load-sensing hydraulic system provides low energy consumption and responsive, comfortable control. Telescoping, lifting, and slewing of the cutting head are controlled via proportional valves. Rear support and slewing cylinders offer 20% greater output force. Multi-valve coordination ensures stepless speed regulation and stable operational performance.

Travel System
Features composite support technology to reduce ground pressure from the tracks, ensuring stable contact. The system offers high tractive force and excellent climbing ability of up to ±18°.

Cutting System
Optimized pick layout ensures balanced force distribution, enhancing cutting efficiency while reducing pick wear. Tungsten alloy pick holders reduce tool consumption by over 30%. A front-end waterproof sealing design increases joint reliability. Optimized output speed and increased torque boost rock-breaking capacity. Enlarged slewing base enhances shock and vibration resistance, increasing service life by 40%.

Loading and Transport System
The gathering plate adopts a front-mounted passive roller and open design to improve loading capacity. One track side features a dual-stage telescopic structure to adapt to various tunnel widths. The scraper conveyor uses high-strength round link chain for smooth operation, while the wear-resistant transport chute is made of 14+6 composite plates, improving wear life by 3–5 times.

Key Machine Features

• Structural parts provide excellent strength, rigidity, and vibration resistance.

• Rotary support lifespan extended by 1.5 times.

• The gathering plate and conveyor system incorporate replaceable composite wear-resistant steel plates for extended durability.

• Cutting motor and gearbox are connected via a flexible coupling, increasing transmission capacity by 1.4 times and effectively reducing vibration.

Power Matching
The lifting and slewing cylinders are optimally matched with cutting power to reduce vibration and pick wear, improving cutting stability and performance.

Modular Design
A modular design approach ensures high parts compatibility. Core components such as bearings, seals, hydraulic pumps, motors, and valve groups are sourced from leading international brands.

Intelligent Integration
Supports local, remote, and surface-based operation modes. Smart capabilities include autonomous positioning, guidance, cutting, online diagnostics, environmental recognition, and plug-and-play connectivity, enabling efficient and safe tunneling in modern coal mine operations.
