The European standard EN-12642 "Load securing on road vehicles - Bodies on commercial vehicles - Minimum requirements" defines the forces that bodies must be able to absorb.

However the technical construction was made must:
  • the full width and up to ¬ĺ of the height of the end wall withstand a force corresponding to 50% of the technical payload.
  • the lateral structure must hold 40%
  • the rear portal 30%

It also specifies the elastic deformation. The structure may bend by a maximum of 300 mm, of which a maximum of 20 mm may remain permanent, provided that the function is not restricted.

Manufacturers provide specific body-related data on each vehicle. As these are not uniform in design, particular attention should be paid here before loading.

We have brought you in our LaSi blog: "Episode 32: Load securing with Code XL bodies". has put together some case studies that you can use as a guide.
In principle, vehicles must comply with the technical regulations /T√úV) and be both operationally and roadworthy. This also applies to load-bearing components such as the vehicle frame, the loading area or the front or side walls of a truck. Possible reasons for the rejection of a truck can be:

  • massive damage/deformation on the frame of the loading area
  • rusted through perforated strip
  • Damage to the tractor e.g. lights
  • Damage / cracks on the tires
  • worn tires
  • Structurally impermissible modifications to the frame of the superstructure
  • Defects on the ship's side e.g. defective ship's side hinges
  • Cracks on the frame of the superstructure
Documentation with pictures and concrete case studies can be found in our detailed technical article: "Episode 30: Damage to the Truck - When Should You Refuse a Load?"
The technical regulation of a truck body can be found in the standard: Load securing on road vehicles - "Bodies on commercial vehicles - Minimum requirements; German version EN12642:2016". In order to evaluate the load capacity of the floor, one must also consult DIN EN 283 "Swap bodies - testing".

In addition, the manufacturer's markings, which are usually located on the rear portal or the inside of the door, also contain relevant information. In the "DGUV 70 vehicles" says in § 37 "Loading and unloading" paragraph: (2) When loading and unloading vehicles must be ensured that they can not roll away, tilt or overturn. Thus, it must also be taken into account whether the tractor is still coupled, or parking supports are extended and perhaps even an additional safety trestle must be positioned under the king pins.
