Hitachi Ltd will complete the world's tallest elevator research tower in Hitachinaka City, Ibaraki Prefecture, Japan, in April 2010.

The total cost of the building, "G1Tower," including related facilities is about six billion yen (approx US$66.5 million).

The height of the nine-story tower is 213.5m above ground and 15m below ground (the first basement level). Its building area is 388m2. The purpose of building the tower is to test an elevator that moves at the world's fastest rated speed of 1,080m per minute as well as to develop one of the world's largest-capacity elevators (5t) that can carry about 70 people and move at a rated speed of 600m per minute.

Hitachi intends to use the research tower to develop a vibration control device and a device to control the air pressure inside an elevator cage so that it becomes possible to ensure a comfortable ride even at a high speed. In addition, the company aims to develop technologies to reduce the space for a hoistway and the weight of a cage.

Hitachi also plans to complete a 172m-high research tower at its manufacturing base in Shanghai, China, in the summer of 2010. It will be the tallest elevator research tower in China. The company will use the tower to develop high-speed elevators for the Chinese market.
