Abstract

A method of providing a support for an elevator car in an elevator installation, wherein the support includes a plurality of tensile carriers arranged parallel to one another and substantially enclosed by a casing, includes pre-preparation of a first support end wherein the tensile carriers are directly electrically contactable at a pre-prepared location by a contacting device, and wherein the pre-preparation is carried out before transport of the support to the elevator installation.

First claim

The invention claimed is:

1. A method of providing a support for use in an elevator installation, the support having a plurality of tensile carriers arranged parallel to one another and a casing, wherein the tensile carriers are substantially enclosed by the casing, the method comprising the steps of:
pre-preparing a first support end of the support by arranging contact elements at the tensile carriers at a pre-prepared location along the support so that the tensile carriers are directly electrically contactable through the contact elements at the pre-prepared location by a contacting device; and
carrying out the pre-preparing step before transport of the support to the elevator installation.

2. The method according to claim 1 including during the pre-preparing step freeing the tensile carriers at least partly from the casing at the pre-prepared location.

3. The method according to claim 1 including dimensioning the pre-prepared location to be guidable through a support fastening device.

4. The method according to claim 1 including a step of mounting a protective element on the support at the pre-prepared location.

5. The method according to claim 1 including performing the pre-preparation steps on a second support end of the support.

6. The method according to claim 5 wherein a distance between the pre-prepared locations of the first and second support ends is greater than a required support length between a first support fastening device and a second support fastening device in the elevator installation.

7. The method according to claim 6 wherein the distance is in a range of 50 to 1,000 centimeters greater than the required support length.

8. The method according to claim 1 including the further steps of:
installing the support in the elevator installation by fastening at support fastening devices;
electrically connecting the tensile carriers at the pre-prepared location to the contacting device wherein the contacting device is connected with a monitoring unit; and
monitoring the support with the monitoring unit by detecting electrical characteristic values of the tensile carriers.

9. The method according to claim 8 wherein when the support means is installed in the elevator installation at least two of the tensile carriers are electrically connected together at a second support end of the support.

10. The method according to claim 8 including performing the pre-preparation steps on a second support end of the support.

11. The method according to claim 10 wherein the contacting device is a first contacting device, wherein when the support is installed in the elevator installation at least two of the tensile carriers are electrically connected together by a second contacting device at the second support end and wherein the tensile carriers are individually electrically measured at the first support end through the first contacting device.

12. The method according to claim 8 wherein when the support is installed in the elevator installation and the support is fastened to the support fastening devices, an excess length of the support is stored behind one of the support fastening devices.

13. The method according to claim 12 wherein the excess length of the support is rolled up and fastened in the elevator installation.

14. The method according to claim 8 wherein when the support is installed in the elevator installation the pre-prepared location is guided through the support fastening device.
