Taski TASK: a heavy EU class O4 trailer from 1990 with a 27,000 kg gross weight, a 12.72 m length and an 8,800 mm wheelbase
The TASK from Taski is a trailer built in 1990. With a gross weight of 27,000 kg it falls into EU trailer class O4, the heavy trailers above 10 tonnes towed behind suitably rated tractor units in long-haul and heavy transport. At 12.72 metres long with an 8,800 mm wheelbase, the TASK is a long, multi-axle example of this class.

An unladen weight of 10,250 kg leaves a payload of 16,750 kg against the 27,000 kg gross weight. The 8,800 mm wheelbase across four wheels supports the 12.72 m length and spreads the heavy load across widely set axles. At 2.53 metres wide, the trailer stays within the regular vehicle width.
Long, heavy O4 trailers of this kind typically carry construction machinery, industrial plant or long structural parts, where both the length of the load bed and a high payload are needed. Because the gross weight exceeds 10 tonnes, such trailers are normally fitted with air brakes and need a towing vehicle rated for a correspondingly high trailer weight.
On a trailer this long and heavy, check the frame along its full length first: sagging in the middle and cracking on the cross members point to past overloading. Also check the air brake system, the condition of the axle bearings, and look for corrosion on the lower chassis parts after decades of use. Any distortion of the drawbar or coupling head is worth a close look too.
