Abstract
A method and an apparatus for automatic condition checking of an elevator are provided, wherein an elevator car of the elevator is situated in a door zone of a first landing in an elevator shaft following an earthquake. The method includes determining whether the load carried by hoisting ropes is evenly distributed between the hoisting ropes by checking the status or measurement data of at least one rope tension measurement device. The test unit determines whether the elevator car is empty and conducts a drive test for the elevator car in order to determine unimpeded access for the elevator car to other landings. The elevator is returned to normal use, if the drive test indicates unimpeded access for the elevator car to the other landings.
