A real-time virtual replica of a physical elevator that mirrors its operational state, enabling simulation, performance optimisation, and predictive maintenance without physical intervention.
Full Definition
An elevator digital twin is a continuously updated virtual model fed by IoT sensor streams, BIM geometry, maintenance history, and operational data. It replicates the physical elevator's kinematic behaviour, load cycles, component wear states, and energy profiles. Engineers use the twin to: simulate the impact of schedule changes on component life; run fault-injection scenarios to optimise maintenance intervals; validate software updates before deployment; and generate predictive remaining useful life (RUL) estimates for ropes, buffers, and door mechanisms. The twin is synchronised in near-real-time and divergence detection triggers field inspection requests. Elevator OEMs and FM software vendors offer twin environments within broader predictive maintenance platforms. Digital twin methodology aligns with ISO 23247 for manufacturing digital twins and with EN 81-20 asset documentation requirements.
