At a length of 10,170 mm, a width of 2,600 mm and a wheelbase of 6,960 mm, the Cools has an unladen weight of 10,990 kg; against the gross weight of 12,000 kg that leaves a payload of only 1,010 kg. The very high unladen weight relative to payload points to a massive, heavy build rather than a light load area.
In class O4, a multi-axle compressed-air brake system is mandatory, and towing requires a category CE licence. With a payload only a little over a tonne, the trailer itself already carries practically all of the permitted weight, consistent with a fixed, reinforced build rather than a general-purpose carrier. A wheelbase of 6,960 mm on such a heavy build points to a short, compact base under a heavy body.
When buying a heavy trailer nearly three decades old, check especially for corrosion on the frame and cross-members, the condition of axles and wheel bearings, and the function and tightness of the compressed-air brake system. Visible fatigue cracking on heavily loaded welds should also be checked, along with the condition of the lighting and electrical connections. Exactly one example of this type is registered in the Netherlands, so spare parts are hard to find through normal trade.
