Cobra – other models: the widely spread collective page of trailers outside the named ranges, from light short codes to 18.6 t low-loaders, 450 to 18,600 kg kerb weight

This page gathers the Cobra-brand trailers the register could not assign to its own named range. The model designations range from short codes such as K, K1, KO, L1, LA, B or C0, through numbered types such as 2105B, 40 RKS, 5512L1 and HR591M, to fully written names such as Cardinal, Tropical Trip, Woonwagen (Dutch for a living-wagon caravan) and designations derived from the vehicle-technology firms A. Spindelberger, Spiegelberger and Eberhard of Mörfelden.

The register lists 22 versions with kerb weights from 450 to 18,600 kg, gross vehicle weights from 850 to 20,000 kg, lengths from 8,980 to 13,900 mm and widths from 1,680 to 2,600 mm.

With a spread from a light trailer to an 18.6-tonne low-loader, this collective page covers an unusually wide field, from car trailers through living-wagon caravans to heavy transporters for construction machinery. As a register placeholder without a uniform range, Cobra therefore represents a cross-section of very different trailer types gathered in the register under one brand name.

When buying used, the inspection depends heavily on the type: on the light trailers, check the axle, brakes and corrosion on the frame and drawbar; on the caravan, also check for damp in the body and the condition of the windows; on the heavy low-loaders, check frame torsion, the brake system across all axles, and the condition of ramps and winches. Spare parts range, depending on the version, from common trailer parts to specialist components for heavy transport.

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.
