Key Product Advantages
1. Powerful & Efficient Powertrain
Equipped with a Weichai WP12G/WP13G heavy-duty engine (up to 390 kW) and a Fast transmission series, it delivers strong torque (2300 N·m) and optimal gear ratio matching for mining terrains. The hydro-pneumatic booster clutch ensures smooth shifting and durability.
2. Superior Load Capacity & Durability
Features a high-strength steel frame and a NM400 wear-resistant cargo box to withstand heavy impacts and abrasion. The 35-ton heavy-duty rear axles with differential lock provide exceptional traction on rough roads.
3. Safe & Reliable Braking
Adopts a three-stage braking system (service/parking/auxiliary) with full air brake design. The spring-energy storage parking brake guarantees safety on 30% uphill slopes, while the exhaust brake + WEVB effectively reduces brake wear during long downhill runs.
4. Operator-Centric Design
The full-skeleton wide-body cab offers spacious seating and an oversized windshield for maximum visibility. The adjustable shock-absorbing seat reduces operator fatigue during long shifts.
5. Low Maintenance Cost
Equipped with a multi-stage dust air filter and long-life components, the truck has extended maintenance intervals (up to 5000 km/500h). The modular design simplifies repairs and lowers operational costs.
Application Scenarios
Ideal for open-pit coal mines, stone quarries, earthwork projects, and large-scale construction sites. It excels in transporting heavy ores, aggregates, and construction materials under high-load, off-road conditions.
Customization Options
Optional configurations include:
- Aluminum alloy fuel tank
- Dual-chamber fuel tank
- Hydraulic retarder
- Back-flushing air filter
- Bottom plate heating system
- Spray device
