Contar – other models: the collective page of trailers and semi-trailers from the Dutch manufacturer outside the named ranges, 480 to 25,780 kg unladen weight, up to 48,000 kg gross weight

This page gathers trailers and semi-trailers of the Dutch brand Contar that the register could not assign to a named range. Contar is one of the Dutch semi-trailer builders for road haulage; type codes such as A 1010 LD or A 18 LC evidently combine an axle count or range code with a letter code for the body type, but cannot be conclusively decoded from the register holdings alone. Depending on gross weight, the braking system ranges from the overrun brake of the lighter class O2 trailers to air brakes with ABS or EBS on the heavy class O3 and O4 semi-trailers; the latter require a category CE licence.

The register lists here 136 versions with unladen weights from 480 to 25,780 kg, gross weights from 2,700 to 48,000 kg, lengths from 6,250 to 15,255 mm and widths from 2,270 to 2,600 mm.

The span runs from light tandem-axle trailers to three-axle semi-trailers in the European standard size; Contar thus competes in the same segment as Pacton, Groenewegen, LAG or Renders.

When buying used, what counts is the condition of the frame and chassis rails (rust, weld cracks), axles and braking system (drum or disc, ABS/EBS), the condition of the curtain, sides or box body, the operation of the landing legs and kingpin, and complete inspection records; on tippers, additionally the hydraulic rams and the tightness of the tipping body. On the semi-trailers, a tandem or tridem axle group spreads the load across several axles, while the lighter trailers usually carry it on a single axle; the 2-inch kingpin is the common standard on the semi-trailers.

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.
  • Compare the chassis number with the papers.
  • Look at the floor, cover or body from the inside — rust does not show from outside.
