Hyundai Elevator has installed two double-deck The El Duo elevators and four high-speed single-deck elevators, which have been operational since March, in the LG Uplus building. The edifice has 21 stories above ground and seven below ground. It serves as LG Uplus Corp.'s headquarters and is located in Yongsan, Seoul. Hyundai Elevator calls the tower the site of "the first operation of double-deck elevators" in the country. Passenger capacity of the double-deck elevators is boosted by up to 1.8 times due to their technology, and these units feature a speed of 4 mps and an adjustable floor-distance device designed by Hyundai Elevator to precisely maintain the floor distance between the upper and lower cabins. Environmentally friendly aspects of the double-deck units include a permanent-magnet synchronous motor and a power-revitalization inverter.
