The escalator truss can last for the lifetime of the building. The mechanical components can wear out or become outdated after a few decades. Safety regulations, as well as the electrical and monitoring systems, have changed considerably in the last 10 or 20 years. And aesthetics can change as quickly as trends in interior design. Given these various lifecycles, it makes sense to take a flexible approach to escalator modernisation. KONE gives you a range of options, so you can replace the entire installation or individual components as needed, with a modular solution.
