The World's Fastest Elevator Hitachi's Challenge in China The World's Fastest Elevator Hitachi's Challenge in China

The World's Fastest Elevator Hitachi's Challenge in China - With advancing economic growth and urbanization, there is tremendous demand for ultra high-rise buildings in Asia's big cities. Accordingly, innovation in vertical infrastructure, such as elevators, has become an urgent issue. One of the ways Hitachi is responding is by creating the world's fastest elevator, which is currently under construction in Guangzhou, China.

Hitachi has a long history of providing ultra-high-speed, large capacity elevators. This history dates back to the 1960s when Hitachi delivered the fastest elevators in Japan at that time to the Kasumigaseki Building, which was one of the nation's first high-rise buildings. Since then, Hitachi has continued in its research and development efforts, responding to the demand for ultra high-rise buildings. In 2010, Hitachi constructed the G1TOWER, which is the world's tallest structure for elevator research*1 and it has been conducting field tests for ultra-high-speed, large-capacity elevators and developing environmentally friendly products. Hitachi has been involved in the elevator business in China since 1980. In 1995, Hitachi established the Hitachi Elevator (Guangzhou) Co., Ltd., which is now the Hitachi Elevator (China) Co., Ltd. located in Guangzhou, this Chinese corporation manufactures, markets and provides maintenance service for elevators. The company began operations in the Guangzhou area and became the top company in China for new elevator construction in terms of market share.
Since then, Hitachi has strengthened its elevator business in China by having Hitachi Elevator (China) Co., Ltd. act as its managing company there. The company has built manufacturing plants in Guangzhou, Tianjin, and Shanghai. One example of results in China is the ultra- high-speed (480 meters per minute), double-deck (two story), large capacity elevators that were put into service in the Shanghai World Financial Center in 2008. In 2013, a new state-of-the-art manufacturing plant was built in Chengdu to provide products and services to meet the changing needs of customers.

1,200 Meters per Minute: A New Challenge for the World's Fastest Elevator*2

2014, Hitachi took on a new challenge in Guangzhou with a project to deliver the world's fastest elevator for the ultra high-rise Guangzhou CTF Finance Centre, a 530-meter-tall building that was under construction. To succeed, the ultra-high-speed elevator would need to be able to go from the ground floor to 95th floor (a distance of 440 meters) in just 43 seconds. This involved not only the technology for power and control, but Hitachi also had to guarantee the safety and comfort of passengers.
The most difficult challenge was keeping the elevator safe and comfortable for riders while reaching speeds of 1,200 meters per minute. Naturally, it becomes more difficult to keep the ride safe and comfortable as the moving speed increases. To resolve these difficulties and create the world's fastest elevator, Hitachi developed one of the world's most powerful permanent magnet motor traction machines (330 kW) and strengthened the durability of the cables that move the elevator cars, which significantly reduced the burden on the traction machines. Further, Hitachi developed an electromagnetic brakes using braking materials able to withstand temperatures of 300 degrees Celsius so that the world's fastest elevator could stop safely and precisely. In addition to the utilization of proprietary power and control technologies, Hitachi focused on the safety and comfort of passengers in the elevator and developed active guides to reduce vibration in the elevator car. Hitachi also added proprietary air-pressure adjustment technology to reduce ear problems associated with changes in air pressure in the elevator car.

Altogether, Hitachi will deliver 95 elevators for the Guangzhou CTF Finance Centre, including two of these world's fastest, 1,200-meters-per-minute elevators, 28 double-deck elevators, and ultra-high-speed elevators that run at 600 meters per minute.

Hitachi's Elevators Make Cities More Convenient and Efficient

In August 2014, Hitachi completed the installation of the elevator traction machine, an essential part for the world's fastest elevator, and the company has been working diligently to be ready for the opening of the Guangzhou CTF Finance Centre in 2016. It has been estimated that 60% of the world's demand for elevators is in China, where more and more high-rise buildings are expected to be constructed. Elevators can be seen as infrastructure for vertical mobility in cities. This is an important factor in making cities more convenient and efficient, along with trains and roads, which are infrastructure for horizontal mobility. To help make urban life more comfortable, Hitachi will continue its efforts to innovate and provide ultra-high-speed, large capacity elevators.
