Abstract
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.

A method for protecting an elevator assembly, the method comprising:
- determining a plurality of operational objectives for elevator traffic;
- selecting one or more of the plurality of operational objectives to be implemented as an operational objective of the elevator traffic based on selection criteria for the operational objective of the elevator traffic;
- forming a movement profile for an elevator car based on the one or more selected operational objectives;
- measuring a physical magnitude of a parameter for the one or more parts of the elevator assembly;
- determining whether the measured physical magnitude of the parameter exceeds a threshold maximum value of the physical magnitude of the parameter;
- and
- decreasing at least one movement magnitude value of the elevator car in the movement profile for the elevator car when the measured physical magnitude of the parameter for the one or more parts of the elevator assembly exceeds the threshold maximum value of the physical magnitude of the parameter for the one or more parts of the elevator assembly.
An elevator assembly comprising:

- and
- a control apparatus configured to,
- determine a plurality of operational objectives for elevator traffic,
- select one or more of the plurality of operational objectives to be implemented as an operational objective of the elevator traffic based on selection criteria for the operational objective of the elevator traffic,
- form a movement profile for the elevator car based on the one or more selected operational objectives of the elevator traffic,
- measure a physical magnitude of a parameter for the one or more parts of the elevator assembly;
- determine whether the measured physical magnitude exceeds a threshold maximum value of the physical magnitude of the parameter for the one or more parts of the elevator assembly, and
- decrease at least one movement magnitude value of the elevator car in the movement profile for the elevator car when the measured physical magnitude the parameter for the one or more parts of the elevator assembly exceeds the threshold maximum value of the physical magnitude of the parameter for the one or more marts of the elevator assembly.
