Abstract: A safety device for an elevator system may include a safety element that in a release position holds a safety system in a deactivated state and in a blocking position activates the safety system. The safety element may exert a driving force configured to transfer the safety element from the release position into the blocking position. A holding element may exert a holding force on the safety element that counteracts the driving force to hold the safety element in the release position. In the release position of the safety element, the holding force exceeds the driving force by a tolerance amount that is adjustable depending on different operating modes that are possible in the release position of the safety element. The safety device may be configured to transfer the safety element into the blocking position, to reduce the holding force such that the driving force exceeds the holding force.

Abstract: A safety device of a lift system may include a car, an evaluation device, and a measuring device. Conditions where departure from a door zone with an open car door or where impermissible accelerations/speeds are reached within the door zone are identifiable by way of the evaluation device and output signals from the measuring device. In such conditions, a control signal may be generated for braking the car. A safety circuit may be connected to the evaluation device and ensure a first safe zone in a shaft head of a lift shaft during an inspection run. The safety circuit may have a safety switch, and the car may include a tripping means for tripping the safety switch. The safety switch and the tripping means have a first relative position upon which the first safe zone is based, and entry of the car into the first safe zone during the inspection run is preventable by tripping the safety switch, which leads to generation of the control signal and braking of the car.
