The Guangzhou Chow Tai Fook Finance Centre also called East Tower, is a 530-meter-tall mixed-use skyscraper in Guangzhou, Guangdong, which was completed in October 2016. It is the tallest completed building in Guangzhou, the third-tallest in China, and the eighth-tallest in the world.
The Guangzhou CTF Finance Centre has a total of 111 above-ground and five below-ground floors and houses a shopping mall, offices, apartments, and a hotel. The skyscraper has a gross floor area of 507,681.0 m2.
The Guangzhou CTF Finance Centre has 95 elevators made by Hitachi, including two elevators that are among the world’s fastest. In 2014, Hitachi announced that those two elevators would be able to reach 1,200 m/min and would carry passengers through the 440 m long shaft from the first to the 95th floor in approximately 43 seconds. In June 2017, the elevators were tested after having been modified to be able to deliver an even faster speed above the rated speed of 20 m/s, and they managed to reach a top speed of 21 m/s. This exceeded the top speed Shanghai Tower’s elevators could deliver which was a top speed of 20.5 m/s, making the lifts within the Guangzhou CTF Finance Centre the world’s fastest.
To achieve their top speed, the elevators in the Guangzhou CTF Finance Centre use permanent magnet synchronous motors. The air pressure is adjusted in order to prevent ear blockages and the elevators have rollers to smoothen the ride. Additionally, the emergency brakes can withstand temperatures up to 300 °C.
Besides the two fastest elevators, the building has 28 double-deck elevators (with speeds of 150–450 m/min.), 13 high-speed elevators (210–600 m/min.), and 52 medium- and low-speed elevators. The designers chose double-deck elevators in order to minimize the number of elevator shafts. The offices, apartments, and hotel all have separate elevators.
