  • Patent number: 10377605
    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.

  • Patent number: 10040665
    Abstract: The tensioning system for the traction belt of an elevator is installed or can be installed in connection with the car and/or the counterweight of the elevator for pretensioning at least one traction belt running between these and comprises means for storing energy. In addition to this, the tensioning system is configured to use the energy stored in the means intended for storing energy for pulling in the traction belt in question for returning tension when the tension of the traction belt falls. The patent application also contains an independent claim for an elevator.

  • Patent number: 10029889
    Abstract: The invention relates to a method for handling and modernizing ropes in an elevator, which elevator comprises at least an elevator car arranged to run in an elevator shaft along the guide rails, a counterweight connected to the elevator car with hoisting ropes from above, a hoisting machinery with a traction sheave above the elevator car, and compensating ropes connected between the elevator car and the counterweight through a compensating mechanism at a lower part of the elevator shaft. The old hoisting ropes and compensating ropes are dismantled when the elevator car has been run to the upper part of the elevator shaft without a risk of losing the friction on the traction sheave.
