LIFT INSTALLATION WITH A BUFFER FOR CREATING A ZONE OF PROTECTION IN A LIFT INSTALLATION AND A METHOD OF CREATING A ZONE OF PROTECTION

摘要

The lift installation comprises a buffer (10) which serves for creating at least one zone of protection in a lift installation, wherein the lift installation comprises a lift cage (15) and a counterweight (23) for the lift cage and the lift cage (15) and the counterweight (23) are movable along paths (V K, V G). The buffer comprises movable means (14, 14.1 ) which can be movable into the path (V K) of the lift cage (15) and/or into the path (V G) of the counterweight (23) in such a manner that the lift cage (15) or the counterweight (23) can be brought into mechanical contact with the movable means (14, 14.1) and the buffer (10) of the lift cage (15) or the counterweight (23) is each supported at a predetermined height (Z1.1, Z1.2) above a floor (18) so that a zone of protection can be realised below or above the lift cage (15).
