With an unladen weight of 5,500 kg, payload comes to 21,500 kg. At 2.50 m wide, with a 4.32 m wheelbase and six wheels, the tank body sits on a compact, multi-axle chassis, typical for cylindrical tanks that concentrate their weight on a short base.
From class O3 upwards, trailers of this size are generally fitted with air brakes rather than the simple overrun brake used on light trailers. Towing it as a combination requires driving licence category C1E or CE in the EU, depending on the combined train weight. Hauling liquids also means the shifting mass inside the tank affects handling under braking and cornering, which is why baffle walls inside the tank divide the load into chambers.
When buying a used unit, the tank shell itself is the key inspection point: check for corrosion inside and out, leaking welds, and the condition of the manhole covers and vent valves. Check fittings, drain valves and hose connections for leaks, listen to the axle bearings for play, check the brake lines for corrosion, and confirm the tank's inspection certificate is current.
