The history of the invention of hydraulic lift for disabled people

As the medieval church spires indicate, construction workers have been able to build tall buildings for hundreds of years. But there was one thing that prevented them from constructing high-rise buildings for people to live and work. Such things are stairs.A hydraulic lift for disabled people is an urgent thing to be solved.

It is meaningless to live in a building above 60 floors, if you have to climb all the passages to reach the apartment. Of course, the simple hydraulic lift for disabled people or cranes that have appeared can help you. They have a hydraulic platform lift that is pulled up by a rope that goes around the pulley. But if the rope is broken, passengers will fall down, so cranes like this can only be used to carry goods.

The person who changed all this was an American mechanic named Elisha Graves Otis. His invention is quite simple, it is a ratchet mechanism. Even if the rope is suddenly broken, it will "catch" the elevator, making it not much downward.

In 1844, Otis set up his test bed at the New York Trade Fair. When there were a large number of spectators, he stepped into the elevator and invited an spectator to cut the cable. The barrier-free lift only dropped by five or six centimeters. Finally, the safety lift stopped.

By the end of the 19th century, elevators were common in offices and suites. Both the elevator and hydraulic elevator are used to push the lift cabin.(hydraulic lift for disabled people)
