Method for mounting and/or removing a covering

摘要

Device for raising and/or lowering a lift comprises a pressure device (402) with a roller (406). The roller is arranged on a traverse (404) so that the roller can be selectively placed on or taken off a cylinder (304) or a lift arranged on the cylinder by a drive (407). The pressure device or the traverse supporting the roller can be displaced so that the distance between the roller and the cylinder can be selectively increased. Independent claims are also included for: (1) Alternative device; (2) Process for raising and/or lowering a lift; and (3) Processes for lowering a lift.
