Abstract

The object of the invention is an elevator provided with a safety device arrangement, which elevator comprises at least an elevator car (1) traveling along guide rails (11) and a safety brake device (3) for stopping unintended movement of the elevator car (1). The safety device arrangement comprises a tuning apparatus (4) disposed on the elevator car (1) for detecting a presence on the roof of the elevator car (1).

Description

technical field [0001] The object of the present invention is to provide an elevator, as defined in the preamble of claim 1 , provided with a safety device arrangement, in particular for working on the roof of the elevator car. Background technique [0002] During elevator operation, situations are encountered when someone has to go to the roof of the elevator car, for example, whether for inspection, maintenance or some other repair. If the height of the ceiling clearance of the elevator shaft is shallow, then, without special procedures, sufficient safe space to prevent personal injury cannot be guaranteed for persons working on the roof of the elevator car. [0003] In this case, the movement of the elevator car and the counterweight must be prevented in some other way than by means of the elevator run actuator. It is known to do this by locking the counterweight in its position on the elevator car and / or on the guide rails, eg by means of safety gear, latches or wedges....
