Humbaur HBTZ – heavy tipper trailer range with sloped side board, 3,140 to 4,650 kg unladen weight, 14,000 to 20,000 kg gross weight

The HBTZ range from the Bavarian trailer maker Humbaur of Gessertshausen comprises heavy tipper trailers. The suffix BS Schräg in the type designations marks the sloped side board, which eases tipping and unloading bulk material; the preceding strings of digits code the load area and payload of each version.

The register lists here 11 versions with unladen weights from 3,140 to 4,650 kg, gross weights from 14,000 to 20,000 kg, lengths from 8,270 to 9,280 mm and widths from 2,470 to 2,550 mm.

With gross weights from 14 to 20 tonnes the HBTZ trailers are built for use behind lorries in earthworks, road building and bulk material haulage; such tipper trailers add extra load capacity to a construction or haulage firm's own lorry fleet. The HBTZ trailers are towed by lorries with a CE driving licence, as is standard in professional freight haulage.

When buying used, what counts is the condition of the body and the sloped side board, the function of the tipping ram and hydraulics, corrosion on the frame and axle mounts, and the condition of the brakes, tyres and lighting; parts for the hydraulics and braking system are supplied through the Humbaur dealer network. The load capacity of the support jack and the condition of the coupling head and safety chain also belong in the 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.
