26DIGGING DEEPERCondition-based maintenanceCondition-based maintenance (CBM) monitors the real-time condition of lifts and escalators based on the simple principle of %u201cDo what is needed, not what is scheduled%u201d. CBM is more cost-effective and efficient than time-based maintenance, which is prone to over-maintenance, and unnecessarily wastes manpower and resources. Prof. Tam and Dr Liu%u2019s innovative approach uses cutting-edge technologies, such as optical fibre sensors and AI, to collect real-time data on the health condition of lifts and escalators. This enables the status and performance of critical components to be continuously monitored. By performing maintenance only when specific indicators show compromised performance, CBM optimises resources, time and costs for maintenance, resulting in smarter and safer lifts and escalators. The team also goes one step further by including predictive functions. These enable worn-out parts and ageing components to be replaced before they fail, minimising unscheduled downtime and service disruptions.PULSE OF THE CITY
