The ZWY-60/22L tire scraper conveyor mining machine is a 22KW low-power energy-saving model. It adopts a tire walking + scraper conveyor structure, making the machine lightweight and flexible. It is specially designed for narrow coal mine roadways and small tunnel projects. It has complete explosion-proof certification, does not jam materials, and has a high throughput. It is suitable for low and narrow underground construction. It is available directly from the manufacturer and supports non-standard customization.
Product Introduction of ZWY-60/22L Tire-Type Mucking Loader
- Product Overview
ZWY-60/22L coal mine excavator loader is a lightweight tire-driven scraper slag removal equipment, specially developed for narrow cross-section roadways, low-height tunnels and small mine drifts. Different from traditional belt conveyor equipment and heavy crawler loaders, this machine adopts an integrated structure of tire walking system and scraper conveyor, combining outstanding flexibility and anti-blocking performance. It serves as a high-performance and cost-effective special machine for tunneling, mucking and roadway maintenance in small & micro underground mines.
Equipped with a 22kW explosion-proof motor, the machine delivers stable slag output up to 60m³/h with smooth and energy-saving power output, perfectly fitting short-distance, low-volume continuous mucking operations. The tire chassis features small turning radius and excellent mobility, enabling flexible movement on flat tunnels, hardened floors and low roadways without damaging the tunnel base. It can be relocated easily without complicated auxiliary equipment, greatly improving trafficability in confined spaces.
The core advantage lies in its scraper conveyor design. Compared with belt conveyors, it effectively avoids belt deviation and slipping, and provides stable conveying performance for crushed rock, coal cinder and mixed slag. It eliminates common faults including material jamming, leakage and belt tearing. The equipment requires simple daily maintenance with low wear and long-term low failure rate, making it ideal for long-term stable operation in small coal mines, metal mines, water diversion tunnels and underground renovation projects.
The whole machine is fully explosion-proof and complies with underground safety standards for coal mines. Its electrical system reaches high protection grade, equipped with multi-protection functions including overload, overheat and hydraulic pressure stabilization to guarantee safe and reliable underground operation. Integrating excavation, material picking, conveying, loading and roadway cleaning in one unit, the machine only needs one single operator, which greatly cuts underground labor cost.
Directly supplied by the manufacturer, the machine supports customized adjustment according to different tunnel widths and construction slopes. We provide one-stop services including factory commissioning, on-site technical guidance and long-term spare parts supply, making it the optimal explosion-proof slag remover for narrow-tunnel small underground projects.
Structural Drawing Description
The attached drawing displays the overall structure of the mining mucking loader, and marks the maximum working width of the front digging arm. This equipment matches standard roadway cross-sections with wide excavation coverage. It can cover most of the working face in one single operation, reducing repeated machine shifting and greatly boosting waste rock removal efficiency, suitable for conventional excavation and mucking tasks in coal and rock roadways.
This schematic diagram shows the overall structure of a coal mine excavator loader (slag loader).
The diagram shows the maximum working width of the excavating arm at the front of the equipment. This equipment is compatible with conventional roadway cross-sections, offering a wide excavation coverage area. It can cover most of the working face of the roadway in a single operation, reducing repeated equipment movements and significantly improving the efficiency of underground waste rock removal. It is suitable for conventional excavation and slag removal operations in coal and rock roadways.
