Abstract

The elevator comprising a car inside an elevator shaft, a landing door to open and close an entrance of the elevator shaft which entrance provides access to a work environment in the elevator shaft. The elevator further comprises a shaft safety system for safeguarding a maintenance worker in the work environment from the car. The shaft safety system comprises a device which is arranged to be automatically activated when said landing door is opened or released to be opened and deactivated by manually reset and a control system for controlling the movement of the car. The device is connected to the control system and the control system is brought in a safely mode wherein the control system prevents the car to move beyond a predetermined position in the shaft in the direction of the work environment if said device is activated. <IMAGE>
