Haven’t seen that. There are multiple companies that do that, but not all of them are reliable. Lift installation is work that requires a lot of skill and attentiveness, and it should not be trusted to random people.
You need to choose a reputable company like Hin Chong Lift Maintenance Services that would be responsible for installation and maintenance to ensure nothing happens while the elevator is used. People’s lives depend on that, and you cannot fool around with things like that. There should be special mechanisms that guarantee safety to people in the elevator in case of an accident.
