The more pertinent the “acknowledged rules of technology” in § 22 Road Traffic Act are required, the clearer it is that the specifications of the various organisations for securing loads are partially overlapped and supplemented. Therefore, it is possible to receive semi-trailers that simultaneously conform to the regulations of the VDI Directive 2700, the Daimler Directive 9.5 and DIN EN 12642 Code XL.
In its VDI 2700 series of directives for acknowledged rules of technology, the Verein Deutscher Ingenieure (Association of German Engineers) has issued numerous topics about securing loads that are each regulated in a sheet. There are sheets about lashing forces (2), load distribution plan (4), bulk goods (6), combined freight traffic (7), paper rolls (9), reinforcing concrete (11), drinks (12), coils (19) and other topics. The publication series is continuously extended.
DIN EN 12642
The European standard DIN EN 12642 is applicable in all member states of the EU, as well as Norway and Switzerland and specifies the minimum requirements for the bodywork on commercial vehicles of more than 3.5 t. It includes a fixed front wall (0.5 x payload), rear wall (0.3 x payload) and sidewalls (0.4 x payload), that – e.g. due to particularly sharp cornering – must not bulge by more than 30 cm before they return to their original condition, resting on the frame of the vehicle. Continuous lashing rings in the external frame and reinforced versions for tarpaulins and stanchions, as well as a minimum of 2 rows of support laths made from wood or aluminium are also part of the equipment.
Thereby, the marking Code XL designates the high stability of the vehicle body. In contrast to the designation Code L, which indicates a superstructure with less strength.
Code XL which encompasses "the suitable for transportating of beverages" designates a vehicle body that is suitable for the special demands on the transportation of well pallets and barrels. The vehicle body is distinguished by reinforced side tarpaulins with 24 closely arranged buckles, as well as a roof tarpaulin with side rail reinforcement. In addition, there is reinforced beverage stanchions and 4 rows of aluminium support laths for the Code-XL drink equipment.
The idea of the Daimler Directive 9.5 is the transportation from and to the works of Daimler AG as trouble-free as possible and contains mandatory methods for securing loads. The directive is based on the statutory regulations for securing loads (Road Traffic Act and German Commercial Code). The equipment of a vehicle for correct securing of loads include a front wall, tested with 0.5 x payload, a rear door tested with 0.3 x payload and 2 pairs of espagnolettes, reinforced roof and side side tarpaulins with 24 Tyride buckles, as well as a minimum of 3 pairs of reinforced stanchions and 4 rows of support laths made from wood or aluminium and a pallet stop. The Daimler Directive 9.5 is increasingly used for all transportation in the automotive sector.
