Abstract
An illustrative example embodiment of an elevator compensation assembly includes a tie down mechanism and at least one compensation sheave that has an outer surface configured to engage at least one compensation rope member. At least one damper is associated with the tie down mechanism for resisting vertical movement of the tie down mechanism in at least one direction. At least one detector directly detects vertical movement of the tie down mechanism along the direction and provides an output indicating at least one characteristic of the detected vertical movement.
Claims23
An elevator compensation assembly, comprising:
- a tie down mechanism including at least one compensation sheave having an outer surface configured to engage at least one compensation rope member;
- at least one damper associated with the tie down mechanism for resisting vertical movement of the tie down mechanism in at least one direction;
- and
- at least one detector that detects vertical movement of the tie down mechanism along the at least one direction and provides an output indicating at least one characteristic of detected vertical movement.
A method of monitoring an elevator compensation assembly that includes a tie down mechanism having at least one compensation sheave and at least one damper associated with the tie down mechanism for resisting vertical movement of the tie down mechanism in at least one direction, the method comprising:
- detecting vertical movement of the tie down mechanism along the at least one direction using at least one detector associated with the tie down mechanism, and
- generating an output indicating at least one characteristic of detected vertical movement.
