The Humbaur HT 35 51 24 is a car trailer from Humbaur (EU vehicle class O2), registered as built in 2005. It is 6,770 mm long and 2,540 mm wide, weighs 860 kg unladen and has a permitted gross weight of 3,500 kg.
Payload for the Humbaur HT 35 51 24, i.e. permitted gross weight minus unladen weight, is 2,640 kg. More than half of the gross weight is therefore available for cargo.
For the driving licence this means: category B allows combinations up to 3,500 kg, code 96 up to 4,250 kg permitted total mass. With a 3,500 kg trailer too little would remain for the towing vehicle even with code 96 – in practice a BE licence is needed, which covers trailers up to 3,500 kg. Being over 750 kg, the trailer must be braked, and the towing vehicle needs a braked towing capacity of at least 3,500 kg.
Among the 416 car trailers from Humbaur with a stated length, the Humbaur HT 35 51 24 at 6,770 mm is in the middle of the range (rank 98); the range runs from 3,190 to 14,594 mm. The Finnish vehicle register lists one unit.
Humbaur HT – range from the Gersthofen maker, single- to triple-axle trailers from 3.5 to 11.9 tonnes gross weight, unladen weight 540 to 3,260 kg
Humbaur, a trailer maker from Gersthofen near Augsburg, runs its multi-purpose and transport trailers in the mid-weight segment in the HT range. The type designation combines the code HT with a multi-digit number coding payload, platform length and axle count, for example HT 3500, HT 353121 or HT 356225 GR, where the suffix GR marks a separate equipment level.

The register lists here 15 versions with unladen weights from 540 to 3,260 kg and gross weights from 3,500 to 11,900 kg, at lengths from 3,950 to 9,380 mm and widths from 1,840 to 2,540 mm.
The HT range thus runs from class O2 to class O3 and covers the field between the classic 3.5-tonne tandem-axle trailer and the larger multi-axle construction and machinery trailer. Such trailers are common in construction and landscaping and with municipalities and hire firms, where they carry construction machinery, small vehicles and material. The HT range is offered both open and with a side-panel body and is often fitted with ramps for self-propelled machinery.
On a used example, rust on the chassis and axles, the condition of the overrun brake and braking system, the function of ramps and lashing points, and tyres and lighting count; on the larger, multi-axle versions also the condition of the axle steering and side panels, plus a look at the service history. Spare parts run through the Humbaur dealer network.

What to check before buying
- Search the frame and welds at the axle mounts — that is where cracks start.

- 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.
