Running containers and bulk cargo on the same trailer without switching equipment is the operational advantage this 12.5m sidewall trailer delivers. The 12 twist locks cover 20ft, 30ft, and 40ft containers at standard ISO positions, while the 0.8m sidewalls contain loose bulk cargo — grain, bagged goods, agricultural products — that a bare flatbed or skeleton chassis can't secure. BPW axles handle the load cycle consistently, and the liftable first axle on full air suspension cuts tire contact and fuel burn on every empty return leg. Aluminum alloy rims reduce rotating weight, keeping more of the legal payload available for actual cargo. The 445/65R22.5 super-single tires carry the load rating without the dual-wheel width penalty. Built and customized at LUYI Vehicle's factory.
