Abstract: A positioning aid positions a nut on a guide rail of an elevator system, the guide rail being formed as a hollow rail, the hollow rail having a plurality of elongated holes arranged one behind the other in the longitudinal direction of the hollow rail in order to be fastened to a guide rail holder. The positioning aid includes an elongate fastening portion to which at least one nut is fastened and which is dimensioned such that it can be passed through one of the elongated holes together with the at least one nut and moved within the hollow rail. The positioning aid also includes a holding portion for holding the fastening portion, the holding portion being fastened to one end of the fastening portion and being configured to be wider than the elongated hole.

Abstract: An elevator system includes a multi-deck vehicle having at least two cars for transporting persons and/or goods, wherein the elevator system is arranged so as to be movable along a track and is coupled to a drive using at least one support device. The at least two cars of the multi-deck vehicle are coupled to each other, the track includes at least one guide rail, and each of the cars of the multi-deck vehicle has at least one guide element that is guided on or in one of the at least one guide rail.

Abstract: An elevator car has an aerodynamic cladding which in an upward travel direction of the elevator car is disposed above an upper side of the elevator car and which is connected with the elevator car. An attachment structure serves as a cladding, which is of self-supporting construction. The elevator car has an opening mechanism which is designed for transferring a movable superstructure of the attachment structure from a closed state to an open state.
