Abstract:
A method of testing elevator car braking distance includes verifying that an elevator car is empty. The method also includes initiating a test procedure. The method further includes triggering a safety actuation device to actuate at least one safety brake to stop an elevator car. The method yet further includes recording braking data during a braking period. The method also includes recording braking data with at least one piece of elevator car equipment. The method further includes generating a braking data report that includes at least one of braking distance and braking deceleration of the elevator car.
