Feber Other models

The register lists 6 versions with a kerb weight of 7,080 to 10,910 kg and a permissible gross weight of 38,000 to 42,000 kg. Lengths range from 9.24 to 12.90 m, with a uniform width of 2.55 m.

With gross weights of up to 42 tonnes, the Feber trailers are heavy semi-trailers used together with matching tractor units for bulk-material haulage. The Wilma designation for gravel and wood points to robust bodies with reinforced platforms or sides, as required for abrasive and heavy bulk loads. The heaviest recorded version weighs about half as much again as the lightest, reflecting the different gravel and wood body variants built on the same platform.

When buying used in this weight class, the condition of the frame and side members matters most, as they take heavy loads during gravel haulage; cracks and deformation at welds are a common weak point. The brake system, axles and tyres should be checked carefully given the high loads, along with wear on the sides and floor covering on the wood-haulage versions. Spare parts for axles and brakes are available through the general commercial-vehicle accessories trade.
