Covers the whole process of assessment, design, construction, acceptance and operation and maintenance of old elevators:

① Safety bottom line: after transformation, must comply with current national standards GB 7588, GB 25194, 100% renewal of safety devices, mandatory replacement of brake systems, door systems and wire ropes;

② Energy-saving upgrade: replace permanent magnet synchronous gearless traction machine, install energy feedback, reduce energy consumption by more than 40%; ③ Intelligent transformation: IoT monitoring, fault early warning, remote maintenance, electric vehicle entry prohibition recognition;

④ Aging-friendly: low-level buttons, voice announcement, handrails, emergency leveling;

⑤ Construction specifications: minimum disturbance, shortest downtime, on-site safety protection, downtime ≤7 days per unit.


The standard provides a unified technical basis for national old community renovation and old elevator renewal, ensuring transformation quality and safety, promoting standardized and high-quality development of old elevator transformation.
