WHAT DOES SPECIFIED LOADING CAPACITY MEAN?

AND WHAT DOES IT MEAN IN TERMS OF CARGO SECURING?

When securing a load, it is useful to make use of the actual body. However, the body must be strong enough to absorb the forces produced. The front wall, for example, must be able to take 50% of the loading capacity in the case of an EN 12642 Code XL body. This is a common topic in manuals and training. But 50% of which loading capacity exactly? Our cargo securing expert Niels Bouwmeester explains in his blog.

PERMISSIBLE LOADING CAPACITY DIFFERS BETWEEN COUNTRIES

These days, loading capacity is referred to as specified loading capacity. That is because the loading capacity can vary from country to country. Let’s take Germany as an example and compare it to the Netherlands. In Germany, the permitted maximum permissible mass (MPM) is 40 tons while in the Netherlands, the maximum permissible mass (MPM) is 50 tons. EN 12642 Code XL tests are often carried out based on a loading capacity of 27 tons while in the Netherlands, it is also possible for these tests to be based on a loading capacity of 32 tons.

WHAT DOES THAT MEAN IN TERMS OF CARGO SECURING?

This difference in loading capacity means that a front wall in Germany will be tested based on 50% of a loading capacity of 27 tons. Here the front wall can take 13,500 daN. In the Netherlands, however, that front wall will be tested based on 50% of a loading capacity of 32 tons. Obviously, this produces a completely different figure, namely 16,000 daN. Therefore as a Dutch citizen, you have 2500 daN less to secure while the body may be exactly the same!

This example calculation applies to the whole vehicle, so including the side walls (40%) and the rear wall (30%). So that is the reason for defining the loading capacity as specified loading capacity.

SECONDHAND XL TRAILER

But what happens if a foreign company purchases a secondhand XL trailer on the Dutch trailer market? Then the maximum permissible mass (MPM) of the trailer will be adjusted for the relevant country (by means of the VIN number) but the values on the original certificate won’t! You will then have the advantage of having less to secure.

ADVICE

So always make sure that the construction certificate is kept with the vehicle. The certificate is leading, not a sticker on the rear door or on the front of the trailer.
