TK Elevator: 20 Years of TWIN


“In the world of urban mobility and sustainable building design, TK Elevator marks a significant milestone as it celebrates 20 years of its revolutionary TWIN elevator. This unique elevator system, housing two independent cabins within one shaft, boasts of energy efficiency, space optimization, and flexibility – all contributing to smarter and more sustainable urban landscapes.

Two decades back, TK Elevator introduced the TWIN system at The University of Stuttgart, creating a paradigm shift in the world of elevators. With its dual cabins operating in the same shaft, TWIN achieved unprecedented efficiency – transporting 40% more passengers and saving 25% more building space compared to conventional elevators. Owners and developers quickly recognized the benefits: energy conservation, enhanced leasable space, and cost-effective construction, winning TWIN the prestigious ‘Project of the Year Award’ in 2003 by Elevator World.

Today, TWIN remains unrivalled, providing architects and developers with unparalleled design flexibility. Traditional double-decker elevators, though effective, were limited by their simultaneous operation and identical floor-to-floor distances, often causing passenger irritation due to ‘phantom stops.’ However, TWIN’s independent cabins bring more flexibility, effectively accommodating buildings with varying floor heights, and enhancing inter-floor connectivity in high-rise structures.

Moreover, TWIN’s forward-thinking design, embedded with intelligent digital controls, significantly improves passenger experiences during peak hours. Through an advanced dispatching algorithm in the AGILE – Destination Control lobby terminal, the TWIN system smartly reduces congestion and wait times, ensuring the fastest route to the passengers’ desired floors. Thanks to state-of-the-art digital design and innovative software, TWIN elevators make for a futuristic, streamlined, and efficient mobility solution.

But it’s not just about efficiency and smart mobility; TWIN also stands tall in the realm of safety. Its robust, TÜV-approved and SIL3-classified safety system ensures the cabins always maintain a minimum safety distance.

Adapting to the ever-evolving digital landscape, TWIN embraced the predictive elevator maintenance system, MAX, after a decade of its launch. Harnessing machine learning, IoT, and cloud technologies, MAX minimizes breakdowns, optimizes uptime, and streamlines building operations – marking another stride towards smart, sustainable buildings.

Speaking of sustainability, TWIN plays a significant role in reducing buildings’ operational carbon footprint. It conserves energy by parking one cabin during low passenger volumes, contributing to immediate energy savings and long-term environmental benefits. An advanced regenerative drive system in TWIN also utilizes the elevator’s braking mechanism to generate electricity, further reducing energy consumption.

From rejuvenating aging high-rises to integrating seamlessly with other elevator systems in skyscrapers, TWIN’s versatility continues to revolutionize urban mobility. Currently, over 1,000 TWIN elevator cars operate globally, making significant strides in green construction and contributing to the creation of sustainable cities.

Notable examples of TWIN’s integration include London’s Botolph Building, where TWIN systems increased leasable space by 6%, Paris’s Trinity Tower, offering passengers a mesmerizing view over the city’s La Défense business district and reducing waiting times by 30%, and New York’s Hudson Yards, the largest private real estate development in U.S. history.

So, as we celebrate 20 years of TWIN, we celebrate not just an innovative product, but the larger vision of TK Elevator – to redefine human mobility, to tread on the path of sustainable construction, and to create a more mobile future. Equipped with regenerative drives, predictive maintenance software, and digital enhancements, TWIN is indeed a testament to TK Elevator’s commitment to innovation and a promise of readiness for whatever the future may bring.”
