How to judge the safety of a villa elevator?
If you want to find out whether a villa elevator which is in the service is safe or not, it can be judged from four aspects:
1. Whether there is an annual inspection certificate;
2. Whether it exceeds its useful life. If the villa elevator is overage, it must be scrapped;
3. Whether the inspections and maintenance of the villa elevator are carried out regularly;
4. Whether the maintenance company of the villa elevator is professionally qualified?
