LOTTE WORLD TOWER, Seoul, South Korea
LOTTE WORLD TOWER
Seoul, South Korea
The LOTTE WORLD TOWER rises 555 meters above the city of Seoul – the country’s first building to exceed 100 floors. Inspired by traditional Korean art forms, its sleek, tapered design offers a striking contrast to the area’s mountainous terrain. To carry visitors to the top, we designed a pair of high-tech double-deck elevators that make the trip in just 60 seconds, travelling at 10 meters per second, making these Sky Shuttles among the world’s fastest doubledeck elevators.
Otis teamed with LG Electronics to transform the one-minute journey into a breathtaking experience all its own. Organic LED (OLED) screens cover each cabin’s walls and ceiling. Once the doors close, passengers find themselves immersed in a virtual journey through the city’s history and its landmarks, including the 14th-century Gyeongbok Palace, the National Assembly Building, Jamsil Baseball Stadium and the LOTTE WORLD TOWER itself. The double-deck elevators each carry 54 passengers at a time – certified by Guinness World Records as the world’s highest-capacity elevators.

Lifeboats to Safety
During an emergency, four SkyRise® elevators function as “lifeboats,” traveling between designated safe zones (Levels 22, 40, 60, 83 and 102) and the ground floor. These evacuation elevators are water- and fire-resistant, and feature back-up power and hoistway pressurization systems.
Unique Expertise for Unique Challenges
Typically, buildings have a flat roof that is still open when elevator machines are lifted from the ground and then lowered into the machine room at the top of the building. But the LOTTE WORLD TOWER pinnacle resembles two spires – an architectural element that complicated installation of four 100-ton traction machines, each weighing more than 21 tons. Special rigging had to be built to maneuver the machines into place without damaging the two spires. In a complex procedure rehearsed multiple times, the traction machines first had to lifted from the ground to a spot on the 124th floor. Once inside, special rigging was used to move the heavy machines into their correct position, safely and precisely – without damaging the spires.
