  • Patent number: 8166886
    Abstract: A wear monitoring system is provided for monitoring the wear and/or abrasion of at least one system component of a cable operated transportation system, where the system component is subjected to wear and/or abrasion and is mounted in rotating and/or circulating manner. A parameter measuring device is provided for measuring an actual value and/or a time-dependent actual value function of at least one electrical and/or mechanical parameter of the at least one system component and/or the drive unit. An evaluating device is provided for determining a parameter deviation of the actual value from a desired value in dependence on time or a time interval and/or of the actual value function from a time-dependent desired value function of the at least one parameter. The parameter deviation corresponds to the state of abrasion and/or the state of wear of the at least one system component.

  • Patent number: 7880633
    Abstract: A cable position monitoring device is provided, for monitoring the position of a cable guided in the rollers of a roller assembly of a cable operated transportation system comprising at least one first and at least one second cable roller defining a reference roller, the cable position monitoring device comprising a movement-magnitude detecting device for determining a first movement-magnitude of the at least one first cable roller and a second movement-magnitude of the reference roller, and an evaluating device for comparing the first and second movement-magnitudes and for determining a mutual movement-magnitude deviation between the first and second movement-magnitudes which corresponds to a safe-to-operate status of the transportation system. An improved cable operated transportation system as well as a method for monitoring the position of a cable of a cable operated transportation system are also provided.

  • Publication number: 20080208519
    Abstract: In order to improve a cable position monitoring device for monitoring the position of a cable guided in the rollers of a roller assembly in at least one first cable roller that is to be monitored of the roller assembly of a cable operated transportation system comprising at least one first and at least one second cable roller defining a reference roller, such that a threatening cable-dislodgement of the cable from at least one cable roller of the transportation system can be recognized in a simple manner, it is proposed that a movement-magnitude detecting device be provided for determining a first movement-magnitude of the at least one first cable roller and a second movement-magnitude of the reference roller, and that an evaluating device be provided for comparing the first and second movement-magnitudes and for determining a mutual movement-magnitude deviation between the first and second movement-magnitudes which corresponds to a safe-to-operate status of the transportation system.
