Abstract:
A method determines a status of at least one component of an elevator system, wherein the elevator system includes a suspension apparatus having at least one traction member. The at least one traction member is surrounded by a non-metallic cladding, wherein the suspension apparatus is guided via a drive sheave with a metallic traction surface. The method includes the steps of: identifying at least one parameter based on an electrostatic effect which occurs due to friction of the non-metallic cladding on the traction sheave with the metallic traction surface; and determining a status of the at least one component on the basis of the identified parameter.
Abstract:
An elevator installation has a car at least partially supported by a support including several electrically conductive tension-bearing elements, which elements are arranged parallel to each other and which are substantially surrounded by a jacket. The support is fastened to fastening devices, wherein the fastening devices each include a housing and a clamping element. The housing and the clamping element each have clamping surfaces, between which surfaces the support is clamped. An electrically insulating material is arranged between at least one side of the support and the clamping surfaces arranged thereon. The electrically insulating material electrically isolates the support from the housing or the clamping element or both.
Abstract:
A support for an elevator car in an elevator installation includes a plurality of tensile carriers, arranged parallel to one another, and a casing. The tensile carriers are enclosed by the casing, wherein the tensile carriers extend along a longitudinal axis of the support. The tensile carriers are freed at least partly from the casing on a section of the longitudinal axis of the support. Contact elements for electrical contacting of the exposed tensile carriers are fastened to the tensile carriers at this section.
Abstract:
A pulley for guiding a belt for carrying a car and/or a counterweight of an elevator system has a plurality of peripheral, axially spaced channels for receiving ribs of the belt. Each of the channels has two opposing channel flanks for force transmission by frictional engagement with one of the ribs and a peripheral groove between the two channel flanks. A width of the groove is at least 25 percent of an axial spacing of the channels and at least 80 percent of a height of the channels.
Abstract:
An elevator system includes a car and/or a counterweight connected to a belt having a plurality of ribs. The elevator system further has at least two deflecting elements over which the belt is guided and which each have a plurality of grooves. The grooves of at least one of the deflecting elements are configured with geometries that differ from the grooves of another of the deflecting elements. The belt has longitudinal ribs that cooperate with the grooves.
Abstract:
An elevator system includes at least one car and at least one counterweight. At least two support means having different physical properties are arranged between the at least one car and the at least one counterweight.
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:
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 system for electrical contacting of tensile carriers in support means includes a support means and a contacting device. The support means has a casing and at least four tensile carriers. The tensile carriers are arranged parallel to one another in the casing and lie substantially in one plane. The contacting device has a contact element. The contact element has a cutting side for penetration of the casing, wherein the cutting side of the contact element is so guided through the casing that the contact element contacts the at least four tensile carriers at least by the cutting side.
