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.
