KONE outlines an elevator modernization approach targeting one-week downtime

Targeted upgrades

In an article published on 21 September 2026, KONE described an elevator modernization approach that it says can be completed in one week or less. The scope includes replacing the controller and upgrading wiring and fixtures while retaining major existing components. The timing is a manufacturer claim about this approach, not a demonstrated schedule for every elevator or tower. [1]

KONE says the upgrades add connectivity and improve reliability, with equipment data supporting earlier identification of problems. Its account identifies service disruption as a reason owners defer modernization and presents shorter outages as a way to make planned upgrades more practical. [1]

Implications for tall buildings

Editorial analysis: For a tall building, the key planning question is how much passenger capacity remains while individual lifts are unavailable. Owners would need a project-specific scope and sequence before applying the advertised timescale. Retaining components also makes their condition and compatibility important inputs to the modernization decision.
