Working Conditions & Application Range of Wheel Mucking Loader

1. Standard Suitable Working Conditions for Wheel Mucking Loader

1.1 Roadway Floor & Ground Requirements

Wheel mucking loaders run on solid mining tires, performing best on hard, flat, dry roadway floors, including concrete ground, steel plates and compact gravel surfaces.

• Suitable ground: flat gravel, cement roadway, track-laid tunnel with no long-term mud or soft soil;
• Unsuitable ground: muddy, waterlogged, loose soil, ground covered with sharp broken rocks, which easily cause tire slipping and trapping;
• Drainage standard: complete drainage system on working face, no standing water soaking tires and chassis.

1.2 Slope Limitation

Tires provide limited friction, so climbing capacity is weaker than crawler mucking machines:

• Standard models: max climbing slope ≤12°; heavy-duty 4WD reinforced models: maximum 15°;
• Only applicable for horizontal tunnels & gentle slopes. Inclined roadways over 15° are forbidden to avoid sliding and brake failure.

1.3 Roadway Cross-section Size

Model ZWY-60/80 fits roadway section ≥2.2m×2.2m; large-capacity ZWY-100 requires section ≥2.6m×2.6m.
Articulated steering design brings small turning radius, flexible reversing in medium-small flat tunnels. For ultra-narrow roadways less than 2m, crawler loaders are recommended instead.

1.4 Muck & Loading Operation Conditions

Designed for regular small broken rock, coal and sandstone after blasting, maximum single rock block ≤600mm.
High continuous mucking efficiency on horizontal tunnels, travel speed 5~15km/h, ideal for frequent transfer between multiple working faces. Not suitable for heavy hard rock or collapsed massive rock excavation.

1.5 Power Configuration Conditions

• Explosion-proof electric version: for gassy coal mines, closed underground tunnels with stable 380V power supply;
• Diesel version: for field tunnels without external power supply, short-distance open pit projects.

2. Full Application Scope of Wheel Mucking Loader

2.1 Mining Industry

1. Non-metal mines: gypsum, phosphate, limestone mine horizontal tunneling & gangue cleaning;
2. Small & medium metal mines: gold, lead-zinc, copper mine horizontal roadway mucking;
3. Low-gas / gas-free small coal mines (explosion-proof wheel loader only);
4. Small open pits with frequent transfer between mining faces.

2.2 Water Conservancy & Tunnel Construction

1. Straight sections of small diversion tunnels and culverts;
2. Short highway & railway tunnel horizontal sections;
3. Urban underground pipe gallery, sewage culvert, civil air defense tunnel excavation;
4. Pipe jacking project, basement foundation pit muck removal.

2.3 General Construction Projects

1. Small foundation pit earthwork transportation, underground passage material handling;
2. Quarry & sand yard short-distance loading and site leveling;
3. Municipal underground pipeline, cable trench excavation & slag removal.
4. Unsuitable Working Conditions (Selection Guide)
5. Inclined roadways, downhill tunnels with slope over 15°;
6. Roadways with permanent ponding, mud or loose soft soil;
7. Long steep tunnels, collapsed hard rock crushing working conditions;
8. High-concentration gassy mines (non-explosion-proof wheel loader prohibited);
9. Ultra-narrow tunnels less than 2m, severely damaged bumpy floors.
10. Core Advantages Matching Flat Roadway Conditions
11. High mobility & fast transfer: faster tire travel speed, high efficiency switching between multiple working faces;
12. Low operation & maintenance cost: simple tire and wheel drive structure, cheaper spare parts, 20%~30% lower purchase price than crawler mucking loader of same specification;
13. Floor protection: no damage to concrete floors and tunnel tracks during operation;
14. Flexible control: articulated steering, easy turning in narrow flat tunnels, light body with low underground moving resistance;

Low energy consumption: less fuel & power cost for continuous horizontal tunnel mucking work.
