The quality of the concrete surface is defined not only by structure, colour surface and flatness, but also by holding forces in the manufacturing process. Screw jacks play a major role in this because they are exposed to enormous forces in extreme environmental conditions. Furthermore, they help ensure the efficiency of the production economically, by the factors “sealed systems” and “low-maintenance”. This is demonstrated, for example, by innovative, separate lubrication. In addition, this process is supported by the use of a central motor, which centrally controls and monitors all lifting gears.
