Harda – other models: the collective page of trailers from light single-axle units to heavy semi-trailers outside the named ranges, types D, DS, DT and DZ, 1,100 to 47,000 kg gross weight
This page gathers the Harda trailers the register could not assign to a named range – from light single-axle units to heavy semi-trailers. The type designations combine a code for the body and axle configuration (D, DS, DT, DZ, DE, DO) with a figure for the weight or size class, such as DS 27, DT 35 or DZE 35. The light D and DT types fall into trailer category O1 or O2 with an overrun brake, while the heavy DZ and DS versions at the top of the weight range fall into category O4 with their own air braking system and ABS.

The register lists here 85 versions with unladen weights of 220 to 14,820 kg, gross weights of 1,100 to 47,000 kg, lengths of 3,430 to 13,900 mm and widths of 1,330 to 2,750 mm.
The span from light car trailers to heavy-duty semi-trailers shows a manufacturer range stretching from the private transport trailer to the commercial long-haul semi-trailer, competing with specialist suppliers in both segments. Such a broad range is not unusual among Central European trailer makers, who carry a continuous line-up from the simple construction-site trailer to the long-haul semi-trailer.
On a used example, check the axle, coupling and lights on the light models, and on the heavy semi-trailers also the frame, braking system (ABS/EBS), kingpin and landing legs, plus tyre condition; parts availability depends heavily on the market concerned.

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.
