What Factors Should Be Considered for Adding Floors to a New Elevator?

In building renovation or functional expansion projects, adding floors to a new elevator is a highly specialized task. Compared with ordinary elevator maintenance, such modifications not only involve changes to the civil structure but also require careful consideration of safety, comfort, and long-term stability of elevator operation. So, what are the key factors to pay attention to when adding floors to a new elevator?

1. Structural Condition Assessment

Shaft space: Confirm whether the existing shaft can accommodate the additional floor height and equipment requirements.

Load-bearing structure: The building must have sufficient load capacity to support the extended guide rails, wire ropes/steel belts, and other components.

2. Equipment Matching and Component Upgrades

Traction system: When lifting height increases, it may be necessary to replace the traction machine or reconfigure the wire ropes/steel belts.

Door system: The added floors must be equipped with corresponding landing doors, door operators, and door control systems.

Control system: Reprogramming is required to add call buttons, floor indicators, and signal systems.

3. Safety and Regulatory Requirements

Limit switches and safety circuits: These must be reconfigured based on the extended travel to ensure safe operation boundaries.

Emergency rescue system: Ensure that after the additional floors are added, the elevator can still respond quickly to emergencies.

Compliance with standards: All modifications must follow national and international elevator safety standards to remain legal and compliant.

4. Construction and Acceptance

The project must be carried out by a professional elevator company to avoid safety risks caused by improper handling.

Upon completion, the modified elevator must pass inspection and acceptance by authorized institutions to ensure safe operation.
