Since it was invented in 1853, the elevator has not changed much.
In addition to the changes in hydraulics, traction or pneumatics, the elevator is still in a square well, perpendicular to the ground.
But recently, German elevator manufacturer Thyssenkrupp announced the completion of the prototype of a magnetic levitation elevator, which is being tested on a 246-meter high tower in Rotterville, Germany.

Similar to the principle of the magnetic levitation train, the prototype uses magnetic tracks to drive the elevator, instead of suspending the car on the traction sheave of the machine room at the top of the elevator shaft as in the traditional way. Due to the reduced friction, the elevator's operating speed can reach 72.4 km/h, slightly higher than the fastest elevator in the world.
The world’s fastest two elevators are currently in the Chow Tai Fook Financial Center in Guangzhou. They are developed by Hitachi and can reach a height of 72 km/h. It takes only 43 seconds to rise from the first floor of the building to the 95th floor.
More forward-looking innovation is that their pivotal elevator tracks can change the direction of elevator operation. This not only means that the elevator can get rid of the only vertical movement mode in the past and can achieve horizontal and vertical movements. It can also allow an elevator shaft to run multiple elevators at the same time.
ThyssenKrupp was founded in 1811 and was originally the largest steel company in Germany. However, after the financial crisis, the global steel market's demand for European steel plummeted. So far, the international steel market is also keen to import cheap steel materials from China.
This led ThyssenKrupp to tilt his business to the elevator sector that was originally just a sideline. In the past five years, the elevator department spent about 400 million euros for research and development. It is not easy for a large company to spend such a huge amount of money on "try crazy things", but this is not without examples: Nokia was originally a paper and rubber manufacturer, but it has become a monopoly for the mobile phone market for a long time. Giants; global logistics system company John Menzies was born in a chain of Edinburgh bookstores.
ThyssenKrupp's successful transformation not only made its profits in the elevator market surpass the steel market, but its invention has now begun to push the elevator industry into new areas.
Although the cost of the magnetic levitation elevator system is 5 times more expensive than traditional elevators, it is difficult to promote it on the market in a large scale. But ThyssenKrupp has signed the first customer, OVG Real Estate.
OVG will install a MULTI elevator in a skyscraper in Berlin called "East Tower" and it is expected to be completed by 2019.
