Abstract
An illustrative example embodiment of an elevator rope sway damping assembly includes a plurality of sway dampers having a width and a length. An actuator device selectively causes movement of the sway dampers in a direction transverse to the length between a first position where the sway dampers are spaced apart by a first distance and a second, sway-damping position where the sway dampers are spaced apart by a second, shorter distance. The actuator device provides an indication when the sway dampers are in the first position.
Claims19
An elevator rope sway damping assembly, comprising:
- a plurality of sway dampers having a length and a width;
- and
- an actuator device that selectively causes movement of the sway dampers in a direction transverse to the length between a first position where the sway dampers are spaced apart by a first distance and a second, sway-damping position where the sway dampers are spaced apart by a second, shorter distance, the actuator device providing an indication when the sway dampers are in the first position,
- wherein
- the actuator device includes a plurality of sheaves and a band that wraps at least partially around the sheaves,
- at least one of the sheaves rotates to cause movement of the band, and
- the sway dampers are supported for movement with the band between the first and second positions in response to rotation of the at least one of the sheaves.
