Embodiment Construction

[0023] figure 1 The schematically and exemplarily shown elevator installation 40 comprises an elevator car 41 , a counterweight 42 and the support means 1 as well as a drive pulley 43 with a corresponding drive motor 44 . The drive pulley 43 drives the supporting mechanism 1 and thereby reverses the movement of the elevator car 41 and the counterweight 42 . The drive motor 44 is controlled by an elevator control device 45 . The car 41 is designed to accommodate and transport people or goods between floors of a building. The car 41 and the counterweight 42 are guided along guide means (not shown). In this example, the car 41 and the counterweight 42 are respectively suspended on the load wheels 46 . The support means 1 is fastened here to a first support means fastening device 47 and is then firstly guided around the support wheels 46 of the counterweight 42 . The carrier 1 is then placed on the drive wheel 43 , guided around the carrier wheel 46 of the car 41 , and finally...

Abstract

The invention relates to a method for determining the state of at least one component of an elevator installation, wherein the elevator installation includes a support means with at least one tension carrier. At least one tension carrier is surrounded by a non-metallic casing, wherein the support means are guided via a drive wheel with a metallic friction surface. The method comprises the steps of: determining at least one characteristic value based on an electrostatic effect which is produced by the friction of a non-metallic casing on a drive wheel with a metallic friction surface when the elevator system is running; and using the detected Characteristic values ​​are used to determine the state of components of the elevator installation.

Description

technical field [0001] The invention relates to a method for determining the state of at least one component of an elevator installation. Background technique [0002] In order to ensure safe operation of the elevator system, various components are monitored in the elevator system. In this way, for example, the travel speed of the elevator car is monitored, wherein the operation of the elevator installation is regulated when it is determined that an impermissible travel speed of the elevator car exists. In addition, the loading state of the elevator car is monitored in the elevator installation. Here, too, the operation of the elevator installation can be regulated when the load of the elevator car is outside the permissible range. In addition, individual components of the elevator system are monitored. For example, the state of the support means is an important indicator for the safe operation of the elevator system. For example, it is possible to determine the traction...
