The case study: drinks in carts

The milk carts are in carts weighing about 400 kg each. Several dozen such carts can fit in a trailer. The carts were secured by means of high-quality aluminium beams that are fastened across the width of the trailer and locked into load securing rails that are attached horizontally to the trailer wall. In itself, this is an excellent cargo securing system, which also offers the possibility of attaching a double load floor, for example. But a limitation of the system is its weight and strength. The beams must be manageable for the driver, which means they should not exceed 20 kg. But they must be strong enough to secure the load.

The type 1839 beams used have a weight of about 15 kg each, an LC ( lashing or thrust capacity) of 900 daN and a breaking strength (BS) of 1,800 daN in the horizontal direction. With three rails at different heights per trailer, a total load securing capacity of 2,700 daN could be achieved This, however, proved insufficient for the milk carts. As these carts may move slightly during driving, much higher dynamic) forces briefly occur on the lashing beams.

Bent beams and damaged rails were the result. However, using heavier beams to achieve a higher breaking strength did not turn out to be a good option. They would become too heavy for the driver to apply smoothly in the loading area. We therefore came up with a smarter system.

Dekra certificate

We have tested the new materials extensively, but there are no official standards for these beams as there are for lashing straps and chains. However, we do make use of the possibility of acquiring a certificate from Dekra in Germany. This is particularly important for hauliers driving to Germany. The lashing equipment is then given a Dekra or GS label, which shows that the type has been inspected.
