Happy Trailer ORPT – semi-trailer range: seven versions from 30 to 45 tonnes gross weight, 6,320 to 9,400 kg unladen weight, 10.9 to 13.85 m length
The ORPT range brings together semi-trailers from the Happy Trailer brand, consistently designated with the ORPT code followed by a number combination such as 30-218, 42-327 or 45-330. The first number consistently corresponds to the size class: higher values stand for greater gross weights, from the lighter 30 versions to the 45 versions of the range. The second number varies within each weight class and marks further build variants of the same base design.

The register lists 7 versions with unladen weights from 6,320 to 9,400 kg at gross weights from 30,000 to 45,000 kg. Lengths range from 10,900 to 13,850 mm, the width is uniformly 2,550 mm.
With gross weights of up to 45 tonnes and lengths of nearly 14 metres, the ORPT range belongs to the semi-trailers of heavy road haulage, as widely used in cross-border European long-distance transport for general and bulk cargo. Hauliers deploy such trailers above all in swap operation between different tractor units, where a robust, low-maintenance base design is valued.
When buying a used trailer of this range, the frame and kingpin mount should be checked for cracks and wear, along with the condition of axles, brakes and suspension, the tightness of the tarpaulin or body, and the function of the landing legs. Tyres, lighting and underrun protection belong to the standard check; spare parts for axles and brakes are available through the general commercial-vehicle parts 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.
