Why do elevator modernization?


Most elevators are built to provide about 30 to 40 years of service,as long as service intervals specified and periodic maintenance/inspections by the manufacturer are followed. As the elevator ages and equipment become increasingly difficult to find or replace, many components require upgrades due to obsolete parts or advances in technology.

 

What is the elevator modernization?


Elevator modernization is the process of upgrading the critical parts of the elevator in order for it to be able to handle new technology, have better performance, improve safety, and even give the aesthetics an up-to-date appeal.
