Herrenknecht HK150T – O4-class trailer with a gross weight of 30,000 kg, an unladen weight of 27,500 kg and eight wheels, built in 2021.

With an unladen weight of 27,500 kg and eight wheels, the HK150T is a very heavily built chassis relative to its gross weight, typical for hauling tunnelling components and machine parts with high point loads: the structure has to carry concentrated loads rather than mainly extra cargo weight.
From class O3 upwards, trailers of this size are generally fitted with air brakes rather than the simple overrun brake used on light trailers. Towing it as a combination requires driving licence category C1E or CE in the EU, depending on the combined train weight. The eight wheels spread the high unladen mass and the point payloads across several axles, so that no single axle load exceeds the permitted range.
When buying a used unit, check the frame and the load-bearing points: cracks and deformation in the reinforcements for point loads matter more on special transporters than on simple load platforms. Check the brake system and air reservoirs for leaks, listen to the bearings on all eight wheels for play, and check the lashing points for wear.

What to check before buying
- Search the frame and welds at the axle mounts — that is where cracks start.
- Check the brakes and the last inspection in the papers.
- Work the gross weight against the towing vehicle before buying.
- Compare the chassis number with the papers.
- Look at the floor, cover or body from the inside — rust does not show from outside.
