摘要： 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.

摘要： An elevator includes a compensating sheave, a compensating rope, a guide, a holder, a driver, a lateral vibration detector, and driver controller. The compensating rope is looped around the compensating sheave to be bent back upward in a hoistway, and has a first end connected to a car and a second end connected a counterweight, the compensating rope suspended from the car and the counterweight. The guide guides the compensating sheave in a vertically displaceable manner. The holder holds the guide to be displaceable in a horizontal direction. The driver drives the holder in the horizontal direction. The lateral vibration detector detects lateral vibration of the compensating rope. The driver controller controls the driver based on a result of detection by the lateral vibration detector and accordingly drive the holder in the horizontal direction so as to dampen lateral vibration of the compensating rope.

摘要： Methods and devices detect a deterioration state of a load bearing capacity in an elevator suspension member arrangement having several suspension members, such as belts, including electrically conductive cords incorporated into an elastomer material. Deterioration is determined by applying alternating electric voltages to the cords included in legs of a circuitry. Phase shifts between the alternating voltages, for example by determining sum voltages and/or differential voltages, provide valuable information about a condition of the belt. A fixation arrangement of the suspension member arrangement is adapted to enable or simplify the proposed measurements. Furthermore, counting a number of performed bending cycles provides further information to be taken into account for determining the current deterioration state of the belts. Overall, deteriorations in a suspension member such as broken cords, shunts between cords, connections between cords and ground potential and/or deterioration due to corrosion of cords may be easily detected.

摘要： A suspension member for suspending and/or driving an elevator car of an elevator system includes a plurality of tension members extending along a length of the suspension member including a plurality of fibers extending along the length of the suspension member bonded into a polymer matrix. A jacket substantially retains the plurality of tension members. The suspension member is configured to be deformed at a suspension member end to allow for installation of the suspension member end into a termination assembly of the elevator system. A method of installing a suspension member of an elevator system into a termination assembly includes deforming a suspension member end and reforming it to a selected shape, inserting the suspension member end into the termination assembly and curing and/or hardening it, and applying a load thereto or to the socket or the wedge to secure the suspension member end in the termination assembly.

摘要： A method for creating a termination by attaching some kind of fitting to the end of a tensile member such as a cable. The end fitting is provided with one or more internal cavities. Each cavity has a proximal portion that is adjacent to the area where the tensile member exits the fitting and a distal portion on its opposite end. A length of the tensile member's filaments is placed within this expanding cavity and infused with liquid potting compound. The method exploits the characteristic of a liquid potting compound as it transitions to a solid. During the solidification process tension is applied. The resulting linear displacement tends to pull the filaments residing in the potting compound into better alignment and improve load sharing.

摘要： A method for creating a termination by attaching some kind of fitting to the end of a tensile member such as a cable. The end fitting is provided with one or more internal cavities. Each cavity has a proximal portion that is adjacent to the area where the tensile member exits the fitting and a distal portion on its opposite end. A length of the tensile member's filaments is placed within this expanding cavity and infused with liquid potting compound. The method exploits the characteristic of a liquid potting compound as it transitions to a solid. Once the potting compound in at least a portion of the cavity has transitioned sufficiently to hold the filaments at a desired level, tension is placed on the tensile member and a small linear displacement may be imposed on the tensile member. This linear displacement tends to pull the filaments residing in the potting compound into better alignment and improve load sharing. The invention can be applied to single fittings having multiple cavities and to multiple fittings having only one cavity per fitting.

摘要： An elevator end termination for an elevator belt includes a wedge housing, a segmented wedge disposed axially within the wedge housing. The segmented wedge includes at least two wedge members spaced apart from one another to define a space therebetween. At least one pressure sensor is disposed in the space defined between the at least two wedge members. The at least one pressure sensor registers compressive pressure exerted between the at least two wedge members. The at least two wedge members may include a pair of adjacent longitudinally-extending wedge members, and a wedge crown adjacent a first end of each of the longitudinally-extending wedge members and separated therefrom by a transversely-extending space. The space is a longitudinal slot between the adjacent wedge members.

摘要： A car for an elevator in an elevator shaft is suspended substantially in the center of gravity thereof at least in a ratio of 2:1 by a carrying apparatus guided via pulleys and is guided through car guides. The car has a car base, a car roof and car walls that define a passenger space. For using the car in a machine room-free elevator, to provide a shaft cross-section as large as possible and to reduce the required shaft pit depth and/or the required shaft head height, at least a first part of one of the pulleys is located between the car base and the car roof and a second part of the pulley is located in the car base or at the same height as the car base or in the car roof or at the same height as the car roof.
