  • Publication number: 20210387832
    Abstract: The invention concerns a method, system and computer program for monitoring the run of a roping interconnecting a car and a counterweight of an elevator and for detecting an abnormal operation condition during the drive of a traction sheave intending therewith the car and the counterweight to be moved via said roping. Said roping is running on its way from the car to the traction sheave via at least one pulley and on its way from the counterweight to the traction sheave via at least one pulley, wherein the rotation of said at least two pulleys is monitored by sensing their rotation. These rotation data are then analysed in view of a mutual correlation indicating therewith a synchronized run of the roping on either side of the traction sheave, and detecting therewith an abnormal situation when detecting an absence of such correlation.

  • Publication number: 20210371241
    Abstract: An elevator safety monitoring system, an elevator system, an elevator drive unit, and a method for operating an elevator are presented. The elevator safety monitoring system includes an elevator car absolute position and speed feedback device, a safety monitor connected to the absolute position and speed feedback device, and a safety zone extending inside an elevator shaft. The safety zone is associated with an allowable maximum speed of an elevator car, wherein the allowable maximum speed is lower than a rated speed of an elevator car outside the safety zone, wherein the safety monitor is configured to determine a slowdown failure of the elevator car approaching the safety zone, and, upon the determination of the slowdown failure, command an actuator to decelerate the elevator car to the allowable maximum speed.

  • Publication number: 20210269283
    Abstract: An elevator car defining an interior space for accommodating passengers includes an openable roof, horizontal roof guide rails arranged on a top side of the elevator car, a support structure pivotably mounted to the guide rails by a first joint, and a working platform pivotably and movably mounted to the support structure by a second joint arranged at a distance from the first joint. The working platform is pivotable between a retracted position, in which said working platform is oriented close to the guide rails in the top side of the elevator car, and a deployed position, in which the working platform is in the interior space, at a distance from the guide rails. The first joint is arranged movable along the guide rails.

  • Publication number: 20210269279
    Abstract: An elevator car roof system is provided for monitoring safety of a service access located on an elevator car roof. The elevator car roof system may monitor a change in an opening state of the elevator car roof. Positions of a plurality of roof panels may indicate when the elevator car roof is partially open, fully open or fully closed. The positions of the roof panels may cause at least one sensor of the elevator car roof system to provide a signal to a control system of the elevator. Further, the elevator car roof system may detect if there is an object on the roof. Based on the detected object on the roof, the elevator car roof system may provide at least one signal to enable controlling operation of the elevator.

  • Patent number: 10850943
    Abstract: A roller guide assembly for an elevator device, the roller guide assembly comprising a base member having a mounting means for mounting to the elevator device, the base member comprising a shaft support member; a roller wheel for engaging a guide rail to be rolled on the guide rail; a shaft on which the roller wheel is bearing-mounted, the shaft being straight and non-rotatably supported by the shaft support member, and a vibration dampening element, the vibration dampening element comprising an elastomer body arranged between the shaft and the shaft support member for dampening vibration of the roller wheel and for isolating the vibration from the base member. The shaft is attached to the shaft support member by the vibration dampening element forming a single attachment point for the shaft.

  • Publication number: 20200283269
    Abstract: An element includes a vibration isolation pad with two opposite substantially planar surfaces, an elastic material layer being permanently attached to a first of the two substantially planar surfaces of the vibration isolation pad, a load sensor arrangement integrated into the combined elevator vibration isolation and load measurement element. A load acting on the combined elevator vibration isolation and load measurement element can be measured with the load sensor arrangement as a function of the compression of the elastic material layer.

  • Publication number: 20200283259
    Abstract: The method includes loading and/or unloading the car, determining whether the car doors are fully closed or not fully open, measuring a total actual axial mass F?act hanging from the traction sheave, determining a stalling limit total minimum axial mass F?min, checking reopening of the car doors, whereby if the car doors are reopened, then return to beginning, else, continue, permitting starting of elevator, comparing the total actual axial mass with the stalling limit total minimum axial mass, whereby if the total actual axial mass is equal to or greater than the stalling limit total minimum axial mass, then permit normal run of the elevator car to the next landing, else, stop the elevator.

  • Publication number: 20190367327
    Abstract: An elevator guide rail mounting arrangement and a method for mounting an elevator guide rail using said elevator guide rail mounting arrangement. The arrangement comprises a plurality of support brackets fixed to an elevator shaft wall and a pair of spring-like fixing clips attached to each of the support. Each fixing clip comprises a first arm being fixed to the support bracket and a second arm bearing and pressing against a lateral foot flange of the guide rail. The arrangement comprises pairs of first fixing clips, which are arranged to provide a frictional holding force to resist the movement of the first fixing clips in relation to the guide rail in the vertical direction, and at least a pair of second fixing clips, which are arranged to allow movement of the second fixing clips in relation of the guide rail in the vertical direction. In the method the guide rail is mounted to the support brackets by pairs of first fixing clips and by at least a pair of the second fixing clips.
