Hitachi Elevator China Co. Ltd. has completed construction of the H1 Tower, one of the tallest elevator test towers in the world, Yahoo Finance reported on January 17. The tower is part of the company’s R&D and manufacturing facility in Guangzhou, China. The 288.8-m structure — which has 273 m above ground and a 15-m-deep basement — will be used to develop elevators and demonstrate leading-edge technologies, and will function as a global base for Tokyo-headquartered Hitachi’s elevator and escalator business. It is equipped with 15 test shafts, including one 250 m long, and can test such technologies as ultra-high-speed elevators, high-capacity elevators, double-deck elevators and control systems.
