Abstract: An elevator includes at least an elevator car arranged to move reciprocally in an elevator hoistway and fitted on guide rails, a plurality of landing doors having landing door locks openable e.g. with a service key, and a safety arrangement arranged to form a safe space, preferably a working space, in the elevator hoistway below the elevator car, access to which safe space is enabled via at least one landing door in the proximity of the base of the elevator hoistway, and/or a safe space, preferably a working space, above the elevator car, to which access is enabled via at least one landing door leading to the roof of the elevator car, and in which elevator the aforementioned safe space has a minimum height. The formation of each safe space is arranged to be implemented as a consequence of the opening occurring, e.g. with a service key, from a floor level of a landing door enabling access into the elevator hoistway.

Abstract: The invention relates to an elevator safety arrangement comprising a hoistway; an elevator car mounted in the hoistway; a working platform on top of the elevator car; at least one movable balustrade, which is movable between a substantially upright position and a substantially horizontal position; and a sensing arrangement for sensing position of the movable balustrade, said sensing arrangement for sensing position of the movable balustrade comprising at least one sensor for sensing position of the balustrade. Said at least one sensor for sensing position of the balustrade comprises a sensor body and a sensor head, and the sensor head is movable relative to the sensor body, and the balustrade is arranged to move the sensor head when pivoted, the balustrade comprising a cam member pivotal together with the balustrade, the cam member comprising one or more protrusions and depressions, and the sensor head is placed against the cam member for being actuated by aid of at least one protrusion and at least one depression of the cam member.
