The register lists an unladen weight of 5,400 kg for this vehicle. Length is 10.95 m and width 2.50 m. Four wheels on a 7.25 m wheelbase carry the load along the full length and are typical for this size in vehicle- and machinery-transport trailers with their own sturdy frame.
Class O3 trailers usually run on compressed-air or hydraulic brakes rather than the simple overrun brake used on smaller classes. At a length of nearly 11 m, the brake system needs good balancing between axles so braking force is spread evenly along the long frame.
When buying a trailer this long, it is especially worth checking for twisting and cracking in the side rails, since the long span creates high peak stresses. The brake system, the bearings on all four wheels and the condition of the deck should be checked, as should possible damp or rust at the ends of the frame. The tyre valves and the spare-wheel mount, where fitted, are worth a look too, since both are easy to overlook during a quick inspection. It is also worth testing the lighting system and its plug connector to the towing vehicle, since contact corrosion here is a common source of faults.
