High-rise buildings are subject to sway due to wind, causing elevator ropes to impact the hoist way, disturbing users, and shortening the elevator’s lifespan. Currently, rope sway is inferred from building sway, but a direct RSMD can more accurately indicate rope sway, improving efficiency and decreasing elevator outages. This study aimed to develop a cost-effective RSMD for the OTIS Elevator Company. The study evaluated various sensor technologies and found that 3D TOF sensors were the most suitable solution due to their accuracy and robustness in measuring rope positions. Sensors were tested and validated using a purpose-built test rig in a hoist way at an OTIS test facility. A system of RSMDs can become the standard monitoring system in the elevator industry, providing real-time information to elevator control systems for improving the safety and efficiency of elevator operations.
