Abstract
Modern elevators involve a plurality of ropes and wheels for ropes in a variety of different functions related to the operation and security of an elevator. The wearing of a rope and a wheel may be inspected by scanning a profile of a wheel or ropes on a wheel. When a rope or a wheel is worn the profile will be lower than in the normal situation. Depending on the difference to the normal situation an appropriate action may be taken.
