Throughout Hitachi’s 90-year history of elevator development, we have remained at the forefront in elevator development capabilities, always looking to the future in order to realize cities of high-rise buildings and of high functionality. We would like to take this opportunity to introduce our technological progress and our efforts aimed at ensuring safety, security and comfort.
Looking to the future, our research and development efforts have remained focused on the creation of safety, security and comfort. With Mito Works as our global mother base, we concentrate on conducting precise simulations and operational tests using actual machines on a daily basis at our G1TOWER, the world’s highest-class elevator research tower. The advanced technology developed through these efforts is used in our production of elevators in order to provide customers with even higher levels of safety, security and comfort.
1260 m/min: approximately 3 minutes to the mountaintop of Mt. Fuji.
We providing new value for people, building systems, and society―――Hitachi’s ultra-high speed elevator, which has been delivered to Guangzhou CTF Finance Centre, a skyscraper complex building in Guangzhou, China, achieved a world record-breaking* speed of 1,260 m/min (75.6km/h). This elevator connects the ground floor to the hotel lobby on the 95th floor in approx. 42 seconds, over a distance of 440 meters. The technology attained from the development of this ultra-high speed elevator will be applied in a bottom-up approach to all Hitachi elevators. In doing so, Hitachi will produce elevators.

The Technology That Supports 1,260 m/min Streamlined capsule structure
Streamlined capsule structure for noise reduction
Controls air current turbulence that occurs at high speed and allows the reduction of noise generated outside the car to achieve quiet performance.
The Technology That Supports 1,260 m/min Rope
Strong and lightweight rope
The rope for an elevator installed in a skyscraper is extremely long and its weight puts a stress on the traction machine. With this in mind, Hitachi newly uses a high-strength material that reduces the weight by approximately 30%. This, in turn, contributes to an elevator’s speed by relieving the traction machine’s burden.
The Technology That Supports 1,260 m/min Emergency stop device
Emergency stop device to securely halt the elevator even in the case of emergency
We developed a braking device that can withstand the high heat generated by friction even in the unlikely event of descent at rapid speed.
The Technology That Supports 1,260 m/min Active guide roller
Active guide roller for suppressing vibration
When car vibration is detected, the active guide roller controls and suppresses it to a level that does not cause discomfort.
In ultra-high-speed elevators, various problems emerge which were not issues before, such as vibration and noise caused by air resistance and tiny bumps in guide rails. Let’s take a look at how Hitachi divided these issues into the three themes of drive performance, safety, and comfort, and developed technologies to achieve the world’s fastest speeds.
The Hitachi Group operates numerous businesses which provide a rich source of experience and know-how that are applied in the development of elevator products.
The flow analysis technology obtained from the car design for rapid transit railways was used to develop the streamlined capsule structure that reduces noise.
Evaluated the aerodynamic sound generated by a 1/12 scale car model to confirm the noise reduction effects of a streamlined capsule structure.
Using the control technology for rolling machines which ensures smoothness and uniformity in thickness of iron products, we prevent any irregular rotation of the traction machine’s motor to allow smooth acceleration and deceleration of the elevator car to ensure riding comfort.
High standard of safety and comfort has always been in our DNA.
Hitachi supports performance retention and problem resolution in the long term to maintain product quality.
Professional maintenance is crucial for safe usage of elevators and escalators in the long term. Hitachi has professionally trained engineers and maintenance tools at each service base.
Hitachi has an established supply system of maintenance parts. Hitachi also organizes technical trainings and seminars both in Japan and over-seas to inform the latest maintenance skills to engineers.
Hitachi proposes a variety of modernization options for aging elevators and escalators such as control system modernization, interior design modernization, and complete modernization in a short period.
With building growing higher and higher in cities around the world, Hitachi is expanding its bases operating in Asia, the Middle East and Europe to provide customers with high quality elevators.
Hitachi’s elevators are operating in buildings, shopping malls, airports, train stations and other facilities around the world.
