01Controller & electrical system
Review the controller, wiring, drive interfaces, landing signals and operating functions. Assess parts availability, diagnostics and integration with the equipment to be retained.
02Drive & traction equipment
Assess the machine, drive and suspension system together. Consider ride quality, mechanical condition and energy use. Regenerative operation, where suitable, needs a project-specific electrical assessment.
03Doors & landing interfaces
Review door operators, panels, tracks, locks and passenger detection. Confirm the condition and compatibility of any landing doors that are proposed for retention.
04Cabin, fixtures & accessibility
Consider cabin finishes, lighting, handrails, buttons, displays and audible information. Check usable space and the effect of changes on car weight, balance and accessibility requirements.
05Safety & emergency functions
Have qualified professionals assess the safety components, leveling performance, emergency communication and applicable rescue provisions. Required changes depend on the existing system and local rules.
06Shaft & retained components
Verify shaft dimensions, pit and overhead clearances, guide rails, brackets, structural interfaces and machine-room access. Retention requires documented condition and suitability; it is not assumed from appearance.
