Product Advantages
1. 80-Ton High-Load Capacity, Meeting Heavy-Duty Transportation Needs
This 4-axle U-shaped rear-tipping self-dumping semi-trailer is specifically designed for heavy-duty transportation, with a maximum load capacity of 80 tons. It is suitable for transporting bulk materials such as sand, gravel, ore, coal, and earthwork.
2. U-Shaped Cargo Box Design for Smoother Unloading
The U-shaped cargo box structure provides a smoother interior, facilitating the concentrated sliding of bulk materials. Compared to traditional square cargo boxes, it effectively reduces material residue and improves unloading efficiency.
3. Rear-Tipping Self-Unloading Method Improves Transportation Turnover Efficiency
Equipped with a reliable hydraulic lifting system, it achieves rapid unloading through rear tipping, reducing manual operation time. It is particularly suitable for scenarios requiring frequent unloading, such as mining areas, construction sites, and sand and gravel transportation.
4. 4-Axle Heavy-Duty Chassis for More Optimal Load Distribution
The 4-axle structure design allows for a more rational distribution of the 80-ton load, improving the vehicle’s stability and reliability under heavy load conditions.
5. High-strength frame, suitable for long-term heavy-duty use
The main frame is constructed of high-strength steel and structurally reinforced for heavy-duty dump transport, possessing excellent bending and torsional resistance, making it suitable for long-term high-intensity transportation.
6. Reinforced cargo box structure, suitable for various bulk materials
The cargo box can be specifically designed according to the transported materials, such as sand, gravel, ore, and coal. The thickness of the cargo box steel plates and related structures can be customized according to actual transportation conditions.
