This is a good video for those who want to learn mechanics, but I'm wondering if it can help if I want to learn how an elevator hoist works. I need it because my house has an old elevator and I would like to know what to do if there is a breakdown when I'm inside. For those with frequent elevator breakdowns, you should know that it is life-threatening because there will be limited oxygen if there is poor ventilation. The quality of the ventilation depends on the proper functioning of the electrics, so to insure yourself against such cases, you may need the help of specialists at hinchong.com. In my opinion, it is better to do everything in advance to exclude the breakdowns and malfunctions of the elevator.
