A safety arrangement for a turning station of an elevator system, comprising:
- at least one first blocking position for preventing, by a first mechanical device, an elevator car from entering the turning station, wherein the first mechanical device is arranged to change its position in response to operation of the turning station;
- and
- at least one second blocking position for preventing, by a second mechanical device, an elevator car from exiting the turning station.
A method for preventing derailment of an elevator car at a turning station of an elevator system, comprising:
- arranging a first mechanical device to prevent an elevator car from entering the turning station when the turning station is in a first blocking position relative to the elevator car;
- configuring the first mechanical device to change its position in response to operation of the turning station;
- and
- arranging a second mechanical device to prevent an elevator car from exiting the turning station when the turning station is in a second blocking position relative to the elevator car.
