It's an electric, crawler-mounted mucking/slag raking loader designed for underground tunnel and mining muck removal. It integrates excavation, conveying, loading and travel functions to improve efficiency, reduce manual cleanup and minimize in-tunnel air pollution.
The product line includes ZWY-60, ZWY-80, ZWY-120 and ZWY-180. Models differ in excavating width/depth/height, loading capacity, weight, motor power and applicable tunnel section size. For example, ZWY-80 is a mid-size unit (≈80 m³/h), while ZWY-180 is the highest capacity model (≈180 m³/h). Ask the supplier for the full model-by-model spec sheet for exact values.
Loading capacity depends on the model: typical values in the range are about 60–80 m³/h for smaller models and up to about 180 m³/h for the largest (ZWY-180). Actual throughput depends on material type, particle size and working conditions.
Conveying is achieved using scraper conveyors, leather-belt conveyors or combinations of scraper and leather-belt depending on the model and configuration.
Applicable working section (width × height) varies by model. Typical minimum clearances given are approximately ≥2×2 m for smaller models, ≥2.2×2.2 m for medium units and larger requirements (e.g., ≥3.8×3.8 m) for the biggest units. Confirm the exact minimum for your chosen model before deployment.
Motor power varies by model. Smaller models use lower kW motors while larger models use higher-power motors (examples in the datasheet show motors from the ~20 kW range up to substantially higher for the largest units). Final motor specification depends on selected model and electrical system — request the electrical data sheet for exact values.
Maximum passing material size depends on model. Example values in the technical table range around 650×700×650 mm to 800×780×800 mm. Actual acceptable size depends on material type and configuration — oversized material may require pre-breaking.
Excavating width and depth vary by model. Typical excavating widths in the range are roughly 3.8–6.5 m (model-dependent) and excavating depth/height values are adjustable per configuration. Refer to the model datasheet for exact excavating dimensions.
The crawler chassis is designed for low-speed travel in tunnel environments. Climbing ability varies by model (examples show climbing capability limits such as ≤10°–≤25° depending on unit). Minimum turning radius and travelling speed also vary by model — consult the spec sheet for the model you plan to use.
Unloading height and distance are changeable/configurable and differ by model. Example unloading heights in the technical table are listed as changeable values (e.g., ~1.1–2.7 m) and unloading distance can be configured to suit site requirements. Confirm desired conveyor discharge arrangement with the supplier.
The machine is designed for stable operation with integrated conveying to reduce manual handling and minimize dust/pollution inside the tunnel compared with manual mucking. Using enclosed belt conveyors and proper ventilation further reduces airborne dust.
Routine maintenance includes inspection and lubrication of crawler undercarriage, conveyors (scraper belts), hydraulic systems, electrical components and wear parts (buckets, scrapers, belts). Follow the manufacturer's maintenance schedule and use recommended spare parts to ensure safe, reliable operation.
Yes. Many parameters are configurable — excavating width/height/depth, conveyor type, discharge height, ground clearance and working pressure can often be adjusted. Contact the manufacturer with your tunnel cross-section, material type and operational requirements for customization options.
The supplier can advise on transport dimensions and weights for the selected model and usually offers installation guidance, commissioning and operator training packages. Always provide site access information and tunnel dimensions in advance to plan lifting and installation.
