New-Generation 4-Axle Flatbed Trailer Optimized for Ultra-Heavy Load and Harsh Mining ConditionsFor large-scale mining, steel transportation and bulk cargo projects in Africa and the Middle East, standard 3-axle trailers often face limited load capacity and overloaded operation risks. Insufficient bearing performance easily causes vehicle overload, low transportation efficiency and frequent part wear. To meet the market demand for ultra-heavy haulage, we have fully upgraded and optimized the new-generation 4-axle flatbed semi-trailer.
