Semi-trailers carry the load in a tractor-trailer combination and are built to suit very different cargoes. This category includes fuel and chemical tank trailers, bulk powder trailers for cement and fly ash, LPG tank trailers, refrigerated trailers, and flatbed and cargo trailers for general freight.
The cargo decides the design. Liquid tankers need the right tank material and compartments, powder trailers need a pneumatic discharge system, LPG trailers are pressure vessels built to gas codes, and flatbeds need the right deck length and securing points. After that, compare the number of axles, the suspension, the tare weight and the tyres.
Tank bodies are available in carbon steel, aluminium alloy and stainless steel. Make sure the kingpin and connections match your tractor heads. Tell us what you carry, the load per trip and the tractors in your fleet.
