The ZWY-80/30L tracked scraper type mining muck loader is equipped with a 30KW explosion-proof power unit, a stable muck output of 80m³/h, and a body suitable for small and medium-sized roadway conditions. It comes standard with a tracked scraper conveyor structure, which is anti-clogging, wear-resistant, and has strong climbing ability. It supports the addition of various attachments such as hydraulic breakers and milling heads, integrating multiple functions such as muck removal, crushing, and roadway repair. It has complete explosion-proof certification, and is available from the manufacturer for customization.
Product Introduction of ZWY-80/30L Tracked Mucking Loader
- Product Overview
ZWY-80/30L coal mine excavator loader is a medium-sized multi-functional tracked underground mucking machine, perfectly matched to the operation conditions of small & medium coal mines, metal mines and tunnel excavation mucking projects. It addresses the defects of insufficient power on small-sized equipment and bulky body of heavy-duty machines. Featuring moderate overall dimensions and outstanding trafficability, plus expandable working functions, it becomes the preferred equipment for multi-purpose underground construction.
Equipped with a 30kW explosion-proof motor, the machine delivers stable continuous mucking capacity up to 80 m³ per hour. It adopts reinforced tracked walking structure with strong ground adhesion, which can easily cope with muddy, stony and uneven underground ground surfaces. The machine is capable of operating on steep slopes with low risk of slipping or jamming, showing far better adaptability to complex tunnels than tire-type equipment.
Fitted with high-strength scraper conveyor system, it boasts superior wear resistance compared with belt conveyors, effectively avoiding belt deviation and material blockage. It ensures stable conveying of hard rock, gravel, wet coal slag and other materials, with lower failure rate and reduced maintenance expenses.
The core competitive advantage lies in its modular attachment expansion design. Pre-installed universal hydraulic interfaces are reserved on the main body, enabling flexible installation of multi-functional attachments such as hydraulic breakers and milling heads according to construction demands. A single machine can complete multiple operations including tunnel mucking, rock breaking, section trimming, trench digging and surrounding rock milling repair. This multi-function design eliminates frequent equipment replacement, greatly cutting equipment procurement cost and simplifying underground machine transportation, making it ideal for complex projects such as tunnel maintenance, landslide cleaning and tunnel reshaping.
The whole machine holds complete mining explosion-proof certifications, with multi-layer safety protection installed on electrical and hydraulic systems. It features easy operation and stable running performance. Integrated with excavation, grabbing, conveying and loading functions, it can be equipped with expandable attachments to fully satisfy diversified underground construction requirements.
The manufacturer maintains sufficient stock and provides customized solutions for special working conditions. One-stop services including machine commissioning, operator technical training and long-term spare parts supply are available. It is a cost-effective multi-functional explosion-proof construction machine for small and medium underground projects.
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.
