摘要： Stall condition in an elevator is potentially dangerous situation if it causes slack to the ropes of the elevator. In such situation a counterweight or elevator car does not move even if the hoisting machine is still operating. This situation may be prevented by stopping the elevator as early as possible after detecting such stall condition. The detection of the stall condition is based on monitoring the torque generated by the hoisting machine of the elevator. When rapid change in the torque is detected a stall condition is suspected. The elevator may be stopped or an alarm may be launched when the stall condition is suspected.

摘要： The invention allows inspection tests for an elevator without additional test weights. An empty elevator car and its counterweight are balanced by filling in weight pieces to the counterweight. 100% load of the elevator car in regard to unbalance is configured by moving unused counterweight pieces inside the elevator car. Inspection tests requiring the 100% load in regard to unbalance are performed. 125% load of the elevator car is simulated with 50% load and 125% speed of the elevator car. Inspection tests requiring the 125% load in regard to unbalance are performed. A final counterweight is configured by moving its weight pieces from the elevator car to the counterweight. Inspection tests requiring the final counterweight are performed.

摘要： The invention relates to a method and an apparatus. In the method there is determined a speed limit or an acceleration limit for an elevator car based on elevator state information, the elevator state information comprising at least information on whether the elevator car is being driven or whether the elevator car is in a floor. Power supply to the motor is disabled and brakes are applying for braking movement of the elevator car. Speed or acceleration of the elevator car is measured, in response to the applying of the at least one brake and the disabling of the power supply to the motor. It is determined whether the at least one of speed and acceleration of the elevator car exceeds the respective at least one of the speed limit and the acceleration limit. Thereupon, power supply to the motor is enabled for stabilizing movement of the elevator car.
