There are currently around 750,000 elevators in Germany, and the number is rising. Due to a shortage of building space, commercial, office and residential buildings are increasingly being built at heights, which is why efficient and trouble-free elevator systems are becoming more and more important. However, the administrative effort for elevator operators is immense and, in addition to often decades of storage of complex circuit diagrams and other documents, more and more know-how and trained personnel are required.
In addition, the trend to buy at the lowest price is fostering a fierce price war among suppliers. This is accompanied by the risk that the systems will no longer be adequately maintained. However, these services are the really lucrative part of the elevator business, because only long-term maintenance contracts ensure high profit margins for suppliers.
