For an office block in Hallbergmoos near Munich, Germany, RP Technik GmbH developed a new installation technique for steel-glass facades in element construction: the filigree System RP-ISO-hermetic 45 with window inset elements RP-ISO-PURAL.

The individual facade elements have a height up to 12 m and a width of up to 5 m, for a total of 60 m² of facade in one piece. These mega-facade elements are installed efficiently with ensured quality at the construction site using a mounting device in the horizontal position, completely glazed and equipped with inset elements. With the help of a newly-designed vacuum lifting device these facade elements are installed in the building in pre-assembled anchorage consoles in less than 15 minutes. The entire mounting time, in comparison to conventional mounting, is reduced by approximately one third - and this without a cost-intensive scaffold for the building. This method sets new standard in facade technology.

The company RP Technik GmbH ( developed the concept for an efficient production and installation method for facades. The facade elements are completely assembled in the horizontal position at the construction site on an assembling device. These individual mega-elements with a size of 12 x 5 m have a total weight of ca. 2700 kg.

The special attachment of the glass-holding cleats of RP steel-glass facades to the carrying profile frame was made possible only through the use of special vacuum lifting technology from us because when such an element is lifted via the glass, this special attachment is the critical link in the chain.

In the RP facade systems the glass-holding cleats are fixed with drilling screws directly into the entire profile wall strength and thus reveal very high values in accordance to the pull out power. They are nearly twice as high as for steel facade systems with screw threads and are therefore without equal in comparison to the lower strip thread values of aluminium facade systems used especially in screw thread technology.

The facade system RP-ISO-hermetic 45 allows also the simple transport from the horizontal position till the vertical inset to the building via special vacuum lifting devices. The most important advantage is that the full attachment into the steel profile wall copes also with the jerky movements of the mega elements which cannot be avoided when transporting by crane.

For the solution to the lifting of the vertical transport and the inset of the mega-facade elements we were contracted to construct the special vacuum lifting device.

Because our constructed vacuum lifting device 7201-HVSO needed also to be used for smaller facade elements, the concept for the device was worked out on the basis of two vacuum lifting devices connected together. Each of these vacuum lifting devices has for safety reasons a redundant vacuum system (2-circuit vacuum system). Each vacuum circuit has its own control vacuum meter and vacuum observation. Via an optical and acoustic warning means, a warning is given to the operating staff if the vacuum of one vacuum circuit is insufficient. The mains operated device has also of course a power failure observation system which signals a missing current supply to the operating staff .
