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: A roller for an elevator system has a roller body made of a metal material and a shell made of a POM material forming a running surface of the elevator roller. The shell and the roller body each have a wave profile running in a circumferential direction on a shared contact surface, wherein the shell has, on the running surface, a V-ribbed profile aligned with the wave profile of the roller body that has a rib spacing which substantially corresponds to a wave spacing of the wave profile. The elevator roller is manufactured using a molding process.

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 installation wherein damage to a support for an elevator car and a counterweight, in particular damage to a sheath of the support, advantageously can be detected. At the elevator installation, a housing at least partially extending around the support, for example at a deflecting roller arrangement. A surface of the housing facing the support is electrically conductive and is electrically grounded. If the support or a wire coming out of the damaged support comes in contact with the housing, an electrical ground fault results. The ground fault can be detected by a security monitoring unit by monitoring a current flowing through the wires of the support, and the damage to the support can thus be inferred.

Abstract: A connection element for electrically contacting tension members embedded into a matrix material of a load-bearing belt for an elevator system has a frame with an upper part, a lower part and multiple electrically conductive contact elements. The frame is shaped to receive the belt in an interior space delimited at at least two opposite sides. The contact elements are formed as stamped and bent metal parts, and some regions of the contact elements are arranged in the upper part of the frame with other regions protruding from the upper part of the frame into the interior space, for example in the form of piercing tips, in order to contact the tension members embedded in the portion of the belt received in the interior space.

Abstract: An elevator installation includes a cage, a counterweight, a drive and at least one support element. The cage and the counterweight are supported by the support element, which is driven by the drive to move the cage and the counterweight in opposite directions. The support element includes at least one test element, wherein the test element is contacted by at least one contacting device and connected with a measuring device so that an electrical resistance of the test element is determinable by the measuring device, wherein the electrical resistance of the test element changes due to stretching of the test element so that through measurement of the electrical resistance of the test element at least one of the following states of the elevator installation is ascertainable: loading of the cage, a slack support element, a tension difference between at least two support elements and damage of the support element.

Abstract: A method for detecting a deterioration state in an elevator suspension member including electrically conductive cords uses a multiplexing unit (MU) to apply first and second alternating voltages to proximal ends of first and second groups of the cords respectively and connect the proximal end of a third group of the cords to a voltage measurement arrangement connected to a reference potential. Distal ends of the groups are connected together. A first neutral point voltage between the third proximal end and the reference potential is determined. The MU is switched to apply the first alternating voltage to the second proximal end, apply the second alternating voltage to the third proximal end and determine a second neutral point voltage between the first proximal end and the reference potential. The deterioration state of the suspension member arrangement is determined based on the first and second neutral point voltages.
