Beijing XX Elevator Maintenance | 68 Elevators Intelligent Monitoring
Pain Points
Managed elevator operational status is opaque; entrapment events rely on property owner phone calls with average 38-minute response time. Maintenance records use paper work orders; annual audit file retrieval takes 5–7 work days. Low customer trust, renewal rate only 78%.
Implementation Plan
Monitoring Targets
Managed elevator operational status, fault codes, door status, and maintenance process records
Pilot Scope
Initial 1–3 pilot elevators to verify stable third-party DTU data integration
Tech Stack
Pilot Acceptance Criteria
