The Trinity Tower is distinguished by two of the TWIN lifts operating in panoramic shafts within the façade that runs the entire height of the building, including three machinery levels. As a result, the occupants of the Tower will benefit from an unprecedented view of La Défense, while passers-by can see the red and yellow cabins up-close as they ascend the length of the tower. The colors were specifically chosen by the architect Jean-Luc Crochon as a tribute to the Eiffel Tower’s historic elevators.
An emblematic project of the Unibail-Rodamco-Westfield Group, the Trinity Tower was designed and built by the architectural firm Cro&Co and under the direct supervision of architect Jean-Luc Crochon. It revolutionizes the concept of the office tower known until now, to meet the new expectations and needs of businesses. The Trinity Tower is an extraordinary project whose construction began in 2016 and was completed in November 2020. The exceptional feature of this tower is that it is built on a concrete slab suspended above a highway.
Trinity will also be the first tower in La Défense to be equipped with panoramic TWIN lifts with exceptional speed, allowing occupants to move quickly between the 33 floors of the skyscraper. Through a glass façade, the effervescence of the tower will be unveiled and visible from the forecourt of La Défense.
TWIN lifts are the first industrial system with two independent cabs operating in a single shaft. Offering an equivalent passenger transport capacity, they occupy up to 50% less space than regular lifts. They also make it possible to establish new traffic concepts and performance records. Each cab is each equipped with a separate traction chain, controller, cables, a counterweight, and a speed governor. An intelligent destination selection control (DSC) device moves passengers faster by grouping together people who want to access the same floor.
The occupants will be able to move smoothly between the 33 floors of the skyscraper, since each cab will serve a specific number of floors (the first cab in each TWIN will serve floors 0 to 15 and the second cab will serve floors 15 to 33).
The architect Jean-Luc Crochon states: “By integrating two lift cabins into the same shaft, TWIN lifts have accentuated movement within the façade. This solution also offers greater agility in managing the traffic inherent in a high-rise building”.
