    摘要: In a method for limiting loading of an elevator assembly, a limit value for a maximum permitted loading is set for one or more parts of the elevator assembly, and a loading of the one or more parts of the elevator assembly is determined. A movement magnitude value of the elevator car in the movement profile of the elevator car is modified to limit the loading of the one or more parts of the elevator assembly if the loading of the one or more parts of the elevator assembly exceeds the limit value for the maximum permitted loading.
