Renovation of Elevators in Old Buildings: Enhanced Safety and Comfort

As cities develop, many old residential communities built in the 1980s and 1990s face common problems with their elevators, such as exceeding their service life, frequent malfunctions, and prominent safety hazards. In recent years, driven by national policies and residents' demands for safety, the renovation of elevators in old communities has become an important livelihood project, implemented across the country.

For example, in a residential community in Hangzhou City, built nearly 30 years ago, multiple elevators have long experienced issues such as unstable operation, loud noises, inaccurate leveling, and even occasional trapping incidents. This has severely impacted residents' travel safety and quality of life. Last year, this community was included in the government's comprehensive renovation project for old communities, with elevator upgrades being a top priority.

The renovation plan focuses on key issues:

1. Core Safety Component Replacement: Thoroughly replacing old overspeed governor, safety gears, and buffers to ensure compliance with the latest "Safety Code for the Manufacturing and Installation of Elevators."

1. Control System Upgrade: Phasing out outdated control systems, improving operational efficiency and reliability, and incorporating self-diagnosis functions to reduce sudden malfunctions.

2. Improved Running Stability: Replacing severely worn traction wheel, guide wheels, and steel ropes, and installing new shock absorption devices to effectively reduce operational noise and vibration, enhancing riding comfort.

3. Energy Efficiency Optimization: Some communities, where conditions permit, have also opted for permanent magnet synchronous gearless traction machines to replace traditional hosts, significantly reducing energy consumption.

After the renovation, residents reported that their riding experience was "much smoother and quieter, the buttons respond faster, and most importantly, we feel more at ease." Such renovation projects are ubiquitous in major cities across the country, effectively addressing safety hazards in old elevators and enhancing residents' well-being and sense of security. These are tangible projects that benefit the people. This trend is expected to continue in the coming years.
