The storage capacity in the shops is not always sufficient. Slabs are therefore also stored in neighbouring outdoor yards. Slab carriers are employed for transport to and from the yards.
The use of these large, four-wheel vehicles, however, requires special storage arrangements.
In order to deposit slabs, the vehicle travels on large wheels between the storage bays. Adjacent storage bays must therefore be separated by a gap of at least 4 metres.
An optimised GPS system appeared to be a suitable means to position the slabs in the outdoor yards precisely and to monitor their exact location. Since the equipment is exposed to the elements at all times (***), it must be particularly robust.
(***): The weather is not the only factor here. The equipment is located on board these large vehicles, which travel on uneven terrain. The shocks cause damaging vibrations and loosen connections. This is an important aspect, reflected in the requirements placed on the equipment.
