Abstract: A method and an apparatus monitor the physical state of a suspension means that is connected to an elevator car and can move the same. The support means has markings along its length that divide the support means into segments. The strain difference of the suspension means is monitored segment by segment using a first strain at a first load and a second strain at a second load being determined by a signal processing unit from a distance between two selected markings detected by a detection device, and a strain difference representing the elastic behavior of the segment is calculated from the two strains, wherein the load acting on the suspension means between the two selected markings is measured by a load measuring device.

Abstract: An elevator installation includes a car and at least one support device supporting the car. The support device has a plurality of electrically conductive tensile carriers that are arranged parallel to one another and which are substantially enclosed by a casing. The elevator installation further includes a monitoring device that connects the tensile carriers or groups of the tensile carriers in an alternating configuration as electrical resistances in a measuring bridge so that electrical resistances of different tensile carriers can be compared with one another by sensing a bridge voltage.

Abstract: An elevator system has a car and a suspension device, wherein the car is least partially carried by the suspension device. The suspension device includes several electrically conductive tension members that are arranged parallel to one another and are essentially enclosed by a jacket. The suspension device is attached to suspension device mounting fixtures, wherein the suspension device mounting fixtures each include a housing and a clamping element. The housing and the clamping element have clamping surfaces between which the suspension device is clamped. The clamping element and/or the housing is made of an electrically insulating material.

Abstract: A method monitors at least one suspension apparatus in an elevator system, wherein the suspension apparatus includes at least one electrically conducting tension load carrying member that is surrounded by an electrically insulating jacket. The method includes the steps of: repeated determination of a value of an electrical characteristic of at least one tension load carrying member or of a group of tension load carrying members; establishment of a mean value on the basis of the determined values; and comparison of the mean value established with a reference value.

Abstract: A method for checking a monitoring system in an elevator installation includes at least one of the steps: a) checking whether the traction carriers are connected to the monitoring device; b) checking whether the suspension devices are connected to the monitoring device; c) checking whether an electrical resistance of a traction carrier is within a range; d) checking whether a difference of an electrical resistance of a traction carrier from an electrical resistance of a traction carrier of the same suspension device is below a threshold value; and e) checking whether a difference of an electrical resistance of a traction carrier from an electrical resistance of a traction carrier of a different suspension device is below a threshold value; wherein the method is carried out before the elevator installation is commissioned after being installed.
