Hyundai Elevator has succeeded in developing the world's first high-speed elevator technology with a carbon fiber belt at a speed of 1,260 meters per minute, a Hyundai Elevator spokesman said on May 21.
The newly developed elevator is the fastest one in existence. It can reach the highest level of the tallest building in the world, the Burj Khalifa (828 meters), in 46 seconds.
In other words, it reduced by 20 percent from the previous record of 57 seconds. "This is the second great achievement following the development of an elevator with a speed of 1,080 meters per minute, which was the world's fastest speed at that time in 2009," the spokesman said.
The study, which was conducted over five years from 2014 with the support of the Ministry of Trade, Industry and Energy, nine domestic companies and institutions, including Hyundai Elevator, Woojin Electric, Shinsung Materials, DYETEC Research Institute, and KTL, participated.
The core of the 1,260-meter-per-minute elevator system is the newly developed carbon fiber belt, which weighs only one-eighth of the metal rope commonly used in elevators, extending the administrative distance, which was impossible to operate more than 600 meters high, to more than 1,000 meters, while reducing electricity use by 30 percent.
In particular, the high frequency of natural vibrations prevents wind and earthquakes that can occur in skyscrapers, enabling safe driving.
In addition, the surface of the carbon fiber belt with excellent thermal stability and tensile strength was coated with polymer materials to strengthen friction coefficient and wear resistance, more than doubling life span.
In addition, various high-tech technologies have been applied. It has armed with global competitiveness with high-speed and high-capacity systems that can run normally even if part of the system is abnormal by applying 9-phase motors, high-performance CPUs, control systems with real-time operating systems, wired capsule cage that reduces air resistance by 7%, and special ceramic safety that strengthens wear resistance and heat resistance.
Hyundai Elevator CEO Song Seung-bong said, "It will be a great opportunity for the development of the Korean elevator industry in that it independently developed the world's first and best technology through joint efforts by Hyundai Elevator, the only native elevator company in Korea, and its partners and research institutes."
Meanwhile, Hyundai Elevator, which marks its 36th anniversary on May 23, is speeding up its commercialization through procedures such as establishing standards for certification in Korea.
It also plans to build the world's tallest test tower in Chungju, North Chungcheong Province, where its headquarters will move in 2022, and install and operate the elevator.
