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.
Modernizing your elevator can improve the safety and reliability of your equipment and increase the value of your building
The value of electrical modification
Old elevator status
1. High cost of accessories.
2. Does not meet the requirements of the new national standard.
3. Long maintenance cycle.
4. High noise and vibration.
5. High failure rate, often sleepy.
6.Low operating efficiency.
Advantages of electrical update
1. Little damage to the building.
2. Short construction period.
3. Low cost.
4. Improve resource utilization efficiency.
5. Targeted elimination of hidden safety hazards
