Hea KU 41/50: heavy eight-wheel special vehicle with a ten-cylinder engine, a gross vehicle weight of 37,000 kg and an unladen weight of 36,240 kg
Nothing certain can be said about the Hea brand for this vehicle, but the figures clearly describe a machine class: a heavy eight-wheel chassis of the kind used for special bodies and work equipment in the heavy-duty class, not for ordinary freight transport.

The KU 41/50 is powered by a ten-cylinder engine. At a gross vehicle weight of 37,000 kg and an unladen weight of 36,240 kg, only around 760 kg separates the two, suggesting that most of the weight sits in a permanently mounted body rather than variable payload. Length is 12,270 mm, width 2,600 mm, and wheelbase 6,400 mm, spread across eight wheels.
At 37,000 kg the vehicle clearly belongs to class N3 for trucks above 12 tonnes. Eight wheels on such a long wheelbase point to several axles spreading the high axle load, as is common on carrier vehicles for cranes, recovery gear or other heavy work equipment.
For a used example of such a heavy multi-axle vehicle, the frame and axle suspension deserve particular attention: cracks in load-bearing welds, the condition of leaf springs or air bellows, and play in the steering knuckles. With ten cylinders it is also worth checking the injection pump and cooling system, since engines of this size run under heavy thermal load in continuous use, and the colour and level of the coolant can reveal an early leak.
