What Components Need to Be Added for Elevator Extension to New Floors?

With adjustments to building structures or increased demands from property owners, elevator extension and renovation have gradually become a common solution. Extending an elevator to new floors not only relates to the stability and safety of the elevator’s operation but also requires corresponding component upgrades to ensure the smooth operation of the elevator and a comfortable experience for passengers.

I. Common Components That Need to Be Added or Replaced for Elevator Extension to New Floors

Guide Rails and Guide Rail Brackets

The addition of new floor stations requires extending or adding car guide rails and counterweight guide rails to ensure the stable operation of the car.

Landing Doors and Door Operator Systems

Landing doors and door frames must be installed on the newly added floors. For the extension of a new elevator, the original door operator system is generally reused. However, if it is an extension of an old elevator and the old door operator has been in use for more than 15 years, the old door operator devices, as well as the landing door devices on other floors, need to be replaced together to ensure the safety and normal opening of the entrances and exits.

Elevator Wire Ropes / Steel Belts

When the lifting height increases, wire ropes or steel belts need to be reconfigured according to the load and height to ensure the safety of the traction system.

Control System Upgrade

The program of the control cabinet needs to be reset to add new floor stop buttons, signal systems, and corresponding floor displays.

Signal System and Call Panels

The newly added floors must be equipped with elevator call buttons, display screens, and related wiring to achieve synchronization with the main control system.

Limit and Safety Devices

With the increase in floors, the upper and lower limit switches and safety circuits need to be reset to ensure the safety of the operation boundary.

II. Construction and Safety Precautions

The renovation plan must be evaluated and designed by a professional elevator engineering team.

All newly added components must comply with national and industry safety standards.

After the completion of the renovation, the elevator can be put into use only after passing the relevant safety inspections and acceptance.
