Sway Minimization System For Elevator Cables
Sway Minimization System For Elevator Cables
US Patent:
5103937, Apr 14, 1992
Filed:
Mar 28, 1991
Appl. No.:
7/677635
Inventors:
Leslie E. Robertson - New York NY
International Classification:
B66B 900
US Classification:
187 1R
Abstract:
A system for limiting oscillation of a stationary or moving elevator cable attached to suspended elevator equipment in an elevator shaft. The system includes a cable oscillation limiting member located at a predetermined vertical position in the elevator shaft. The limiting member is movable between an extended position vertically in line with the suspended elevator equipment and horizontally proximate the cable in its free-hanging state and a retracted position vertically out of line with the equipment and horizontally distal the cable. The extended position tends to limit oscillations of the cable and the retracted position permits the elevator equipment to pass the member without interference from the member or members and without substantial contact between the elevator equipment and the member under normal operating conditions. The system includes sensors to determine the need for moving the limiting member between its extended and retracted positions, depending upon the position of the elevator. The system may also use the magnitude of forces tending to induce oscillations in the cable for determining when to move the limiting member to and from the extended and retracted positions.
