The samples are loaded over the limits until fracture in order to also confirm the calculations

under real-use conditions..

The power bridge is able to span over up to 8 metres of free distance. The load is not conducted

into the roof framework, but directly into the statics of the building

Thermal analyses and strength calculations of individual parts and the components have made

possible an optimisation of the product with view to the price as well as to technology.
