Technical Examples
  1. The present invention relates to a method and a system for testing the condition of the brakes of an elevator. In the method, a test weight is set to apply to the drive machine of the elevator, by means of which weight a first torque required for driving the elevator car in the upward direction is measured. At least one of the brakes of the elevator is closed. Next, the empty elevator car is driven in the upward direction with the force of the aforesaid first torque and a check is carried out to detect movement of the elevator car. If a movement of the elevator car is detected, then the aforesaid at least one brake of the elevator is regarded as defective. The method of the present invention makes it possible to check the operativeness of the brakes of the elevator without separate maintenance visits.
