Fliegl ASS – semi-trailers from Triptis and Mühldorf: 367, 372 Schwergut and Thermo versions, 4.7 to 8.8 t unladen weight, 27 to 42 t gross weight
Fliegl, the German vehicle builder with plants in Triptis and Mühldorf am Inn, builds semi-trailers for freight transport in its ASS range. This page covers the ASS 3, ASS 367, ASS 372 SCHWERGUT, ASS 372 Thermo and ASS 382 Thermo versions, the suffixes Schwergut and Thermo mark the reinforced and insulated versions respectively. As is usual with semi-trailers, the tractor unit alone provides the drive and part of the braking effort, while the trailer supplies the axles, brakes, tyres and load area.

The register lists here 5 versions with unladen weights from 4,740 to 8,840 kg, gross weights from 27,000 to 42,000 kg, lengths from 7,060 to 10,200 mm and a width of 2,550 mm.
With gross weights up to 42 tonnes and lengths up to just over 10 metres, the ASS counts among the semi-trailers of general and temperature-controlled freight transport used by hauliers for general cargo, food and heavy goods; Fliegl competes here with Krone, Schmitz Cargobull and Kögel. The Thermo versions thereby serve food and pharmaceutical transport, while the Schwergut variant is designed for compact, very heavy general cargo.
On a used trailer, check for rust on the frame and underrun protection, the condition of axles, brakes and tyres, on the Thermo versions the tightness of the insulation and the operation of the refrigeration unit, and a complete inspection history; spare parts run through the Fliegl dealer network. Tyre tread depth and age, and the condition of the wheel chocks and warning equipment, also belong in a pre-purchase check.

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.
