Aluminium silo semi-trailers of this type are common in European agricultural and building-materials haulage, since the light metal saves several tonnes of payload per run compared with steel versions. Benalu ranks among the established makers in this segment, supplying hauliers in grain, feed and cement transport. As semi-trailers with a kingpin and fifth-wheel coupling, these vehicles fall into class O4 for heavy trailers above 10 tonnes, which need a category CE licence to tow.

When buying used, check the aluminium tank's weld seams for cracks and the discharge flaps and compressor connections for leaks. The axles, brake system and kingpin condition should be inspected, along with any dents or corrosion where the tank meets steel components. Spare parts for axles and valves are supplied by dealers specialising in silo and tanker semi-trailers.
