The Future of Elevator Safety System

摘要

The today's safety system of elevators has not been changed since many years. What had been changed are the applications. Buildings reach now 1km in height which puts high demands on safety components such as overspeed governor and safety gear. On the other hand modernization is still one of the most important businesses not only in Europe. Space requirements and functionalities are the challenges. Wittur, as an elevator industry key player for safety components and safety systems is active in creating new products. Safety gears which do not need a conventional mechanical overspeed governor is one of such a solution. Safety levels and functionalities needs to be considered in another way. The elevator world is working also in other new concepts, like multiple cars running in non-pure vertical wells powered by electromagnetic drive. This requires a complete revolution of safety system. One key product would be an electronical safety brake on the car which norms and regulations needs to follow.
