Abstract

In a lift system, a support means is guided over a drive and over a deflection pulley. A cover is arranged on the deflection pulley. The support means entering or leaving the deflection pulley is at least partially covered by the cover. The cover is monitored by a monitoring device so that deformation of the cover by the support means can be determined.

Description

technical field [0001] The invention relates to an elevator installation with a monitoring device and to a method for monitoring a support mechanism in an elevator installation. Background technique [0002] In elevator installations, steel cables are conventionally used as supporting means for supporting and / or driving the elevator installation. Depending on further developments of such cables, it is also possible to use a belt-like carrier with a tension carrier and a sheath arranged around it. Such a belt-shaped carrier is guided in the elevator installation similarly to conventional steel cables by means of drive wheels and deflection rollers. Unlike the steel cables, however, the belt-like carrier is not guided as a whole in a groove in the deflection roller or the drive wheel, but the belt-like carrier is essentially placed on the deflection roller or the drive wheel. [0003] In elevator installations, the support means do not always run exactly perpendicular to the...
