Several fundamental requirements need to be fulfilled in the elevator construction and lift technology sector to ensure the safety of passengers and the reliability of the conveyor technology. First, the cables used in the process have to withstand severe mechanical loads. Therefore, they should exhibit high flexible fatigue strength because several hundreds of rides per day are quite common for passenger lifts in office buildings. This means permanent stress also for the cable technology - throughout several years.
Naturally, lifts also have to comply with the highest standards in terms of personal safety. Among other, structural fire protection plays a decisive role. The obligations with respect to admissible materials are particularly strict. Furthermore, the safe wiring of elevators naturally implies much more than the mere energy supply while ensuring compliance with fire protection.
