Core Products and Market Layout of Special Semi-trailers

Mining Special Semi-trailers: Specifically designed for mining transportation scenarios, they feature high-strength steel and reinforced frame structures. The wear-resistant layer of the cargo box is made of special alloy materials, capable of withstanding the impact and wear of minerals. They are suitable for material transportation in various mining environments such as open-pit and underground mines, with a load capacity 20% higher than that of conventional products.
