When Is Elevator Modernization Necessary?

1. End of Service Life
According to national standards, the recommended service life for ordinary residential elevators is 15-20 years. After this period, even with regular maintenance, the aging of major components will accelerate, and the failure rate will increase significantly.

2. Frequent Malfunctions and High Repair Costs
If your elevator experiences more than 3 malfunctions per month, or if repair costs increase year by year, exceeding 30% of the price of a new elevator, modernization is more economical and safer than continuous repairs.

3. Outdated Technology and Low Operating Efficiency
Older elevators with relay control systems have high energy consumption and slow response times; early variable frequency drive (VFD) technology was immature, resulting in poor leveling accuracy and an uncomfortable ride.

4. Significant Safety Hazards
Door system problems: Abnormal opening and closing of doors, failure of anti-pinch devices

Aging braking system: Excessive braking distance or elevator slippage

Electrical safety defects: Reduced insulation performance, risk of short circuits

5. Non-compliance with Current Safety Standards
The "Safety Code for the Manufacture and Installation of Elevators" (GB 7588-2003), implemented in 2016, sets higher requirements for landing door strength, car unintended movement protection, etc. Many older elevators no longer meet these standards.

6. Inability to Meet Usage Requirements
Hospitals and nursing homes: Need to add stretcher functionality

Residential buildings: Insufficient carrying capacity, long waiting times during peak hours

Commercial buildings: Slow operating speed, affecting office efficiency
