The key facts

  • Two Otis SkyRise elevators at a height of 597.2 m in Tianjin 117 received a Guinness certificate in the category
  • Otis is the sole supplier of elevators and escalators for the skyscraper, with 266 units of equipment installed in total
  • Completion of the Tianjin 117 project is scheduled for the end of 2027

A record at a height of 597.2 meters

Two Otis SkyRise elevators installed in the Tianjin 117 skyscraper in Tianjin, China, at a height of 597.2 meters have received an official Guinness World Records certificate in the category

How the record-breaking elevators are built

The SkyRise elevators combine high-precision engineering solutions with intelligent communication systems and are designed for passenger comfort at high speeds and over long travel distances. The cabins are soundproofed and aerodynamically shaped: computational fluid dynamics methods and wind tunnel tests were used in their design, which reduces noise from air flows and softens pressure changes during rapid movement. Hoisting machines, control systems and ultra-strong steel cables provide the necessary power and precision under heavy loads at the speeds typical of supertall buildings. The Otis ReGen regenerative technology returns the energy generated when the elevator brakes back into the building's power grid. Intelligent systems allow equipment operation to be monitored in real time, passenger flow to be managed, and preventive maintenance to be carried out based on data analysis, which reduces downtime.

Otis's role in the Tianjin 117 project

Otis, one of the world's leading companies in the development, installation, maintenance and modernization of elevators and escalators, is the sole supplier of elevator and escalator equipment for Tianjin 117. In total, the company has installed 266 units of equipment in the building, and also carries out the special engineering and installation work required for operation at the record height. Tianjin 117 is a supertall skyscraper that is expected to set China's record for the height of the highest occupied floor. Completion of the project is scheduled for the end of 2027; it is intended to showcase advanced achievements in high-rise construction and elevator engineering.
