description
XCBH320 Series Double-Drum Roadheader
The XCBH320 series roadheader features stable overall performance, a heavy-duty body with a low center of gravity, and a well-balanced structural layout. It is specially designed for coal and semi-coal rock excavation and is suitable for roadway construction in rock formations with a hardness of up to F9.
This series is developed with a focus on safety, reliability, and easy maintenance. Key components are sourced from internationally renowned brands, and all structural parts are manufactured, processed, and inspected in strict accordance with quality standards. The roadheader boasts a compact design, flexible operation, high availability, and a long service life.
It can also be integrated with a single-rail hydraulic four-boom roof bolter to form a rapid tunneling system, significantly improving excavation efficiency in coal mining applications.
Key Features of the XCBH320 Series Roadheader
Robust Structural Design
The main structural components offer excellent strength, rigidity, and vibration resistance. The rotary support system has been upgraded, extending its service life by 1.5 times. Large-area wear surfaces on the gathering blade and loading conveyor use replaceable composite wear-resistant steel plates for enhanced durability.
Enhanced Power Transmission
The cutting motor is connected to the reducer via a flexible coupling, improving transmission capacity by 1.4 times and effectively reducing vibration and shock during operation.
Optimized Power Matching
The lifting and slewing cylinders are precisely matched with the cutting power, significantly reducing cutting vibrations and pick consumption.
Modular Design
Adopts a modular approach to design and manufacturing, ensuring a high degree of parts interchangeability. Core components such as bearings, seals, hydraulic pumps, motors, and valve groups are sourced from top-tier international brands.
Intelligent System Integration
Supports multiple operation modes, including local, remote, and surface-based control. Intelligent capabilities include autonomous positioning, guidance, cutting, online diagnostics, environmental recognition, and plug-and-play system connectivity.
