- Compilation Basis
All ZWY series model codes comply with the national coal industry standardMT/T 154.1 issued by China Mining Products Safety Approval and Certification Center (aqbz.org). All models are MA-certified explosion-proof underground loading equipment for coal mine tunneling and mucking operations.
1.1 Standard Letter Code Definition
| Code | Full Name | Technical Explanation |
| Z | Mucking & Loading | Underground mine loading equipment category code |
| W | Trackless Travel | Crawler-type trackless mobile structure for tunnels |
| Y | Hydraulic Drive | Full hydraulic control & transmission system |
| L | Tracked Chassis | Universal crawler undercarriage for complex roadways |
| Digital Suffix | Capacity & Power | Core parameters for official MA certification filing |
1.2 Series Official Definition
ZWY Series Crawler Hydraulic Mucking Loader: MA-certified explosion-proof trackless loading machinery, specially designed for underground mine tunneling, gangue removal and material transportation, widely used in coal mines, metal mines and tunnel projects.
1.3 Standard Model Format
Format: ZWY-Mucking Capacity(m³/h)/Installed Power(kW) L
Rule: Mucking capacity first, motor power second, fixed parameter sequence for official safety certificate and nameplate marking.
1.4 Standard Model Examples
- ZWY-80/30L: 80m³/h mucking capacity, 30kW motor, mini crawler loader for narrow tunnels
- ZWY-120/55L: 120m³/h capacity, 55kW explosion-proof motor, standard medium-duty mucking machine
- ZWY-150/55L: 150m³/h high-efficiency loader for medium-large tunneling working faces
- ZWY-180/55L: 180m³/h heavy-duty crawler mucker for large-section roadway excavation
1.5 Core Product & Certification Advantages
- MA Certified Explosion-proof Performance: Equipped with flameproof motor compatible with 660V/1140V underground power supply, compliant with GB3836 explosion standards, safe for high-gas coal mine operation.
- Strong Trafficability: Heavy steel crawler chassis adapts to muddy, rocky and inclined roadways, maximum climbing angle up to 32°, suitable for horizontal and inclined tunneling.
- Integrated Hydraulic Operation: Integrates digging, mucking, conveying and unloading functions, replaces manual operation and improves underground construction efficiency greatly.
- Wide Application: Compact structure fits tunnel sections from 2.3m to 3.5m, applicable for coal mines, metal mines and infrastructure tunnel projects.
