Elevator origin

Elevator origin: (1743)

The first elevator was built during the reign of King Louis XV, in Versailles in 1743 and only for the king to use. This ladder was built outside, in a small yard so that the king could from his room on the first floor and the second floor to meet his lover, Mrs. DE Châteauroux. This technique is based on counterbalance (contre-poids) so the use is less labor intensive.

It was first made in London (Regent's Park Coliseum) in 1829. It could contain dozens of passengers.

OTIS elevator (1857)

The first elevator for the public was inaugurated in 1857 in New York. Made by Elisha Graves OTIS, the American made for EV HAUGHTWOUT & Co., a 5-storey store on Broadway. Mr. OTIS introduced the first New York elevator in 1852, a hydraulic lift (Ascenseur hydraulique) 1867

Léon ÉDOUX (1827 - 1910) installed two hydraulic piston-lift machines (appareil élévateur à pistons hydrauliques) at 21m height at the exhibition at PARIS in 1867. He named it ASCENSEUR.

The emergence of hydraulic elevators has been popular in the United States since 1789, 20 times faster than OTIS in 1857. The development has been reduced by having to dig very hard cylindrical blocks (very deep cylindres). . However, Éouxoux made an elevator for the EIFFEL tower 160m high in 1889. DUOLIFT (1984)

In 1984, the hydraulic lift where the 3rd floor of the Eiffel Tower was replaced by DUOLIFT, a method that does not need counterbalance, was invented by ASCINTER-OTIS. Four cabins can transport 80 passengers over 160m at 1.8m per second.

Electric elevator: (1880)

Elevator today

Electric elevator was first invented by SIEMENS & HALSKE company for an industrial exhibition at Mannheim in 1880. It was 22m in 11 minutes. It transported 8,000 passengers in a month to the top of the observation deck for the exhibition area. The first electric tower over 200m was built in New York in 1908. Then the electric elevator was the fastest to run the device. for Sunshine Building in Japan at a speed of 36km / h. Since 1993, MISUBITSHI has built a Japanese elevator with a speed of 45km / h

This elevator was invented because Émile LETZ of Belgium (Belgique) and EBEL (gold medal in Batima in 1983), is an innovation in its simple way. Just one wall to carry it, one nail attached to the wall, the elevator chamber is attached to a nut (écrou) rotating around the screw. A motor up and down with the elevator chamber. There is no room for machinery, so there is no pulley, no weight, no counterweight, especially when there is a period of emergency when damaged. This type is unique to Rothschild Hospital, Ritz Hotel .
