The invention relates to a method for operating an elevator installed in connection with a building, particularly a high rise elevator, in which method the expected rope sway is monitored using building acceleration data obtained by means of a sensor to calculate a building sway, and whereby based on the building sway and the position of an elevator car a rope sway is estimated, which rope sway is compared with a threshold value to determine excessive rope sway and to deduct operation measures for the elevator in order to counteract a determined excessive rope sway. According to the invention a succession of following steps is performed: This leads to an early detection of a possible excessive rope sway happening in the future in course of servicing elevator calls by the allocated elevator car.

Method for operating an elevator

The invention relates to a method for operating an elevator installed in connection with a building, particularly a high rise elevator, in which method the expected rope sway is monitored using building acceleration data obtained by means of a sensor to calculate a building sway, and whereby based on the building sway and the position of an elevator car a rope sway is estimated, which rope sway is compared with a threshold value to determine the amount of rope sway and to deduct operation measures for the elevator based on the amount of the rope sway, characterized by the succession of following steps

In the technical field of elevator systems, so as to provide a measure for preventing an overspeed governor rope inertia from unwantedly engaging a safety gear in an overspeed governor system, which has a governor rope connected to a moving mass of the elevator system, a machinery brake for decelerating the moving mass so as to perform a quick stop of the moving mass, a safety gear mounted to the moving mass, a synchronization linkage for tripping the safety gear and a synchronization linkage blocking device for blocking the synchronization linkage and/or a governor brake for braking the governor rope, it is determined whether a quick stop of the moving mass is performed, and the governor brake or the synchronization linkage blocking device is activated when the quick stop of the moving mass is performed.

Method for avoiding unwanted safety gear tripping in an elevator system, controller adapted to perform such a method, governor brake and elevator system each having such a controller

In an elevator system, so as to avoid unwanted safety gear tripping, the kinetic energy, which is caused by inertia of the overspeed governor rope to the lever arm, is dissipated by implementing fluid viscous damping to dampen the rotary movement of the spindle shaft to prevent unwanted safety gear tripping in the event when the upwards movement of the moving mass is decelerated by a machinery brake to perform a quick stop of the moving mass. The fluid viscous damping is effected by a viscous fluid damper which is arranged in the synchronization linkage mounted to the moving mass.

The object of the invention is an arrangement for damping lateral sways of a rope-like means fixed to an elevator car in an elevator hoistway, the bottom end of which rope-like means comprises an upward opening bottom loop. A detachable damping means producing a mass effect is disposed to be supported by the top surface of the bottom loop.

A method for controlling an elevator installed in a building that includes an elevator car arranged to travel in a hoistway between floor landings that are at different heights, one or more ropings connected to the elevator car, a hoisting machine for moving the elevator car, and a control for control the hoisting machine is provided. In the method, the sway data of the building is determined, which data describes the strength of the sway of the building, and the starting position data of the elevator car is determined, which starting position data contains data about the starting position of the elevator car and/or data about how long the elevator car has been in the starting position, and the settings for the run speed of the next run are determined on the basis of the starting position data and the sway data. An elevator is configured to perform the method.
