Wiler – other models: heavy semi-trailers of the WT, WTK and WP ranges, 7.3 to 16.4 m long, 28 to 48 tonnes gross weight
This page gathers the Wiler trailers the register could not assign to a named range. The type designations follow a clear pattern: the range abbreviation (WT, WTK, WP, WAK) is followed by a figure for axle spacing, and the final digits state the tonnage – suffixes such as 30T, 36T or 48T denote 30, 36 or 48 tonnes gross weight.

The register lists here 52 versions with unladen weights from 4,100 to 10,865 kg and gross weights from 28,000 to 48,000 kg. Lengths range from 7,320 to 16,410 mm, widths from 2,410 to 2,600 mm.
With gross weights of 28 to 48 tonnes and lengths beyond 16 metres, these trailers belong to the heavy class for articulated haulage in construction materials, heavy freight and earthmoving, where multi-axle semi-trailers spread the permitted axle load over a larger area. Their use is centred on professional haulage rather than private trailer operation.
When buying used, the value hinges on the condition of the frame and cross members after years of heavy-duty service, the function of the air suspension and brake system, play in the axle steering knuckles and signs of cracking on highly stressed welds. Spares for axles, brakes and suspension are available through the commercial-vehicle and semi-trailer trade.

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.
