Sandvik UH320 Flex

The body is 13.6 m long and a notably wide 3.5 m for road use, where 2.55 m is the norm. Unladen weight is 16,000 kg, leaving a payload of 8,000 kg. The high unladen weight against a comparatively moderate payload points to a heavy, low-built chassis, designed for carrying machinery rather than bulk goods.

A vehicle exceeding the standard 2.55 m width needs a special oversize-transport permit within the EU, often with an escort and route check. Class O4 requires an air-brake system with its own supply line from the towing vehicle. Tractor unit and trailer must be joined by a coupling rated for the high axle load and the width. Such a low deck also simplifies driving equipment on and off under its own power, avoiding the need for separate loading ramps at both ends.

Buyers should check the low-built chassis for distortion and corrosion, especially around loading ramps or decks for machinery, and the brake system including lines and actuators. The axles should be checked for play, the tyres for even wear across the full width. A current roadworthiness certificate and the oversize-transport permit are also worth checking.
