In most cases, securing the load with form-fit securing methods is the best, simplest and safest solution. In practice, however, it is often unclear which boundary conditions must be met for this to actually work. <\/p>\n\n

Boundary conditions from the standards<\/h2>\n\n

EN 12642 has been around since 2007 with the unwieldy title: “Securing loads on road vehicles – Bodies on commercial vehicles – Minimum requirements; German version EN 12642:2016<\/em>“.<\/p>\n\n

Most use the common short title “EN-12642 Code XL”. During the development of the standards, the superstructures were divided into two groups. The so-called standard superstructure code L<\/strong> with maximum strengths of the superstructure and the reinforced superstructure code XL<\/strong> with minimum strengths. <\/p>\n<\/div>\n<\/div>\n\n

<\/div>\n\n

The specifications relate to the front wall, the side walls and the rear portal. Testing of the floor load is not included because this is already included in EN-283. The standard gives body manufacturers a lot of freedom as long as the tested strengths are within the specifications. <\/p>\n\n

The following overview is an excerpt from the standard with the current specifications. The letter “P” stands for the technical payload of the vehicle or body. For standard semi-trailers, this is usually 27,000 kg. <\/p>\n\n

The strength of the end wall must be tested over the entire width and up to three quarters of the height. This area must be taken into account to ensure positive locking. Pay particular attention to the loading width. <\/p>\n\n

For the shipper, there are also three important control aspects, namely<\/p>\n\n
