I want to use my property right certificate to install elevators in underground parking spaces, so that two cars can be put in one place. What's wrong with this idea?

The law has no similar provisions on the three-dimensional space of real right, but you'd better say hello to the property before you do it. As far as the cost is concerned, it only takes about 22,000 yuan to upgrade the gantry crane from 2 tons to 2 meters, which is definitely cheaper than buying another parking space. Just brush some butter on the guide rail regularly during maintenance, which is very simple. In terms of safety, the priority of elevator design must be safety. Only 2M elevators are used several times a day. Even after several years of use, there is basically no problem at all. Even if there is, it will take some time to replenish hydraulic oil and lubricate the rusty guide rail. Don't worry about insurance. The cylinders of this elevator are all equipped with explosion-proof devices. I have been engaged in elevators for four or five years, and I have never heard of table failure. If you have any questions about the elevator, you can ask me. I am a knowledgeable person.
