摘要:
The invention relates to a method and arrangement for installing an elevator, which comprises an elevator car arranged to run in an elevator shaft along the guide rails, a balancing weight connected to the elevator car with suspension ropes and with a traction member, the elevator comprising further a hoisting machinery with a driving wheel in the lower part of the elevator shaft below the elevator car, the installing comprising one or more jumps to make the elevator serve higher floors. During the jump phase extensions needed for the suspension ropes are taken from first supply reels and extensions needed for the traction member are taken from second supply reels.
摘要:
An elevator is equipped with a plurality of remote monitoring sensors for detecting faults and other events in a variety of components in the elevator. These remote monitoring sensors produce remote monitoring messages having a priority classification according to the fault or monitoring event severity. These remote monitoring messages are processed according to the priority classification and available communication connection properties. Based on the processing the communication connection for transmitting the remote message to a central system is selected and sent or temporarily stored for later transmittal.

An elevator system includes a control for controlling an elevator into an idle state and/or for cancelling the idle state. The elevator system is configured to receive data from a control circuit external to the elevator system, and the control is arranged to form a control command for controlling the elevator into an idle state and/or for cancelling the idle state on the basis of data received from a control circuit external to the elevator system.
摘要:
An arrangement for reducing the displacement of an elevator car caused by a change in loading includes at least an elevator car configured to move up and down in an elevator hoistway and one or more counterweights, and also at least one rope element above the elevator car and at least one rope element below the elevator car and at least one pretensioner of the rope elements. The elevator car and counterweight are configured to be supported and moved via the rope elements and the pretensioner and rope pulleys, of which rope pulleys the first part are diverting pulleys, and the second part are traction sheaves. The arrangement additionally includes at least two hoisting machines. In the arrangement is a mechanism configured to lock at least two rope pulleys to be non-rotating at least during loading of the elevator car.
