An elevator arrangement is proposed to comprise
- an elevator shaft including at least one fixation structure (5),
- suspension traction means (7) comprising a plurality of electrically conductive cords,
- an elevator car which is at least partly carried by the suspension traction means (7) and
- a fixation arrangement (9) for attaching the suspension traction means (7) in a load carrying manner to the fixation structure (5). Therein, the fixation arrangement (9) is adapted such as to provide for an electric isolation between the suspension traction means (7) and the fixation structure (5). The electrical isolation may be established e.g. using an isolation member (45) such as an electrically isolating washer (47) being interposed between an upper support member (37) supported at the fixation structure (5) and connected to a clamping member (35) via a longitudinal connection member (39), on the one side, and a load carrying structure (25) of the fixation structure (5), on the other side. Due to such electric isolation, monitoring of an integrity of the suspension traction means (7) by applying and monitoring an electric voltage to its cords is possible even in cases where the cords in the suspension traction means (7) are electrically connected to the clamping member (35) e.g. due to damages in an isolating jacket enclosing the cords. Furthermore, a method for modernizing an existing elevator arrangement is proposed. |
