Abstract: The invention relates to methods and arrangements for creating a safe working space in the upper part of an elevator shaft. A position of an elevator car in the elevator shaft in relation to a plurality of safety levels in the elevator shaft may be monitored, where each safety level is associated with a separate clearance of the elevator car from a ceiling of the elevator shaft. The elevator may be controlled to create a safety space zone at the upper part of the elevator shaft. The controlling may include progressively activating separate braking systems in response to the elevator car progressively moving upwards through separate triggering limits of separate clearances, to progressively strengthen an arresting of upwards movement of the elevator car through the elevator shaft.

Abstract: According to an aspect, there is provided an elevator car parking brake. An operating fork is configured to move within a housing in a direction perpendicular to an end surface of a guide rail in response to operating an actuator. When the actuator is operated to move the operating fork within the housing towards the guide rail to achieve a braking state, the operating fork is configured to push braking wedges towards side surfaces of the guide rail to contact the side surfaces. When the actuator is operated to move the operating fork within the housing away from the guide rail to achieve a brake release state, detaching means are configured to pull the braking wedges away from the side surfaces of the guide rail.

Abstract: The solution relates to controlling a generation of an elevator landing call. In the solution, at least two different types of sensors are monitored. In response to a detection that the at least one first type sensor generates an indication on a detection, data indicating a detection by the at least one second type sensor is inquired. If the data inquired does not indicate the detection by the at least one second type sensor a signal is generated causing the generation of the elevator landing call. If the data inquired indicates the detection generated by the at least one second type sensor a generation of the signal causing the generation of the elevator landing call is prevented.

Abstract: Elevator safety and safety related information needs to be sent reliably to safety controlling systems. Existing elevator communication devices may be used for transmitting this information by processing the received safety and safety related information and processing it before sending it over the communication bus from the elevator car or floor equipment to the controlling devices. A separate communication unit may be used for receiving and processing safety and safety related data packets before they are transmitted over a common bus used for safety and safety non-critical submission.
