Product Description

product imformation 

The EBZ135 roadheader is a high-performance equipment tailored for coal mining and tunnel construction, integrating efficiency, safety, and adaptability. Its compact short fuselage, low center of gravity, and robust structural rigidity deliver exceptional climbing capacity (up to ±18° gradient) and superior stability, ensuring reliable operation in complex underground environments. With a total weight of 44t and dimensions of 8.9×2.8×1.5m, it balances power and maneuverability for confined workspaces.

The electric control system is a core advantage, featuring explosion-proof and intrinsically safe switch boxes and operation boxes. These components are small, lightweight, and flexible to operate, while the sealed main controller shell effectively shields against electromagnetic interference. The LCD screen provides real-time working status display and a menu-driven interface, enabling safe and convenient parameter adjustment. Multiple protection functions-including overvoltage, motor overload, phase loss, short circuit, overtemperature, and leakage lockout-prioritize operational safety for operators and equipment.

The hydraulic system adopts advanced constant power, pressure cut-off, and load-sensitive control technologies. Key components are sourced from internationally renowned brands, guaranteeing durability and consistent performance. The cutting head, optimized via simulation technology, uses high-quality picks from the US brand Kenanmat. Its rational pick layout enhances rock-breaking efficiency, easily handling coal with hardness up to 60MPA, and achieves a cutting range of 4.74m (height) × 4.84m (width).

The spray system combines internal and strengthened external spraying, with a reasonable external spray design that effectively reduces dust, improving underground air quality and working conditions. The first conveyor features a straight structure, lapping smoothly with the shovel to ensure stable material transportation at 56m/min. The traveling drive system integrates a motor and reducer with advanced international integrated technology, delivering large output torque and a traveling speed of 0-6m/min, suitable for large-inclination operations.

For logistics convenience, the EBZ135 supports disassembly when facing weight or height restrictions during transportation. Its non-detachable parts have a maximum dimension of 3.4×1.25×1.28m and weight of 5460kg, simplifying loading and unloading. With a loading capacity of 4.3m³/min, it boosts work efficiency, while the average ground unit pressure of 0.131Mpa minimizes ground damage. Additional features include a 500L oil tank, 3-8MPa wall water supply pressure, 0.18m ground clearance, and 0.2m undercut, further enhancing its practicality.

Ideal for coal mining, tunnel construction, and underground engineering projects, the EBZ135 roadheader meets the demanding requirements of heavy-duty excavation. It combines power, safety, and flexibility, making it a reliable choice for improving construction efficiency and reducing operational costs.
