  • one aspect of the invention consists in considering or maintaining the assembly order of the precast concrete elements in the production plan as well as in the stacking plan so that the precast concrete elements are removed from the production line in the same or in the toppled order and without interim storage directly to a stack per Laying plan can be summarized.
  • a sequence that corresponds to the set assembly order is understood to mean that the component marked in the installation plan as the first seton ready component to be mounted in accordance with the production plan of the Production line is removed as the first component or is removed, which has the consequence that this first precast concrete element in the laying plan corresponding stack finished concrete precast elements represents the lowest element.
  • This variant will therefore be selected when the precast concrete elements for transport to the construction site individually on the means of transport, such as a low loader, charged, since in this case the order in the stack is again toppled, that is after completion of the loading is the Stack lowest element, which is formed by the first to be assembled on the construction site precast concrete element to lie on top of the transport so that the ranking of precast concrete elements on the transport from top to bottom corresponds to the installation order specified in the laying plan.

In addition, the maximum time per power stroke allows a predeterminable lead time for a pallet form through the production line, whereby production jams can be avoided.
