AXIEZ-LINKs, the Japanese market standard model elevator launched in October 2020, is newly equipped with a "connect with people function" that increases operational efficiency and comfort, a "connect with buildings function" that connects elevators to building facilities, and a "connect with city" function that collectively manages the elevators in multiple buildings. Together, these functions contribute to the realization of smart buildings.
The "connect with people" function can optimize the operation of multiple elevators according to the flow of people into buildings as predicted by our AI technology. The elevators are standard-equipped with circulation fans featuring our trademark Health Air® function*1 that controls airborne substances, buttons with anti-viral properties, buttons that can be actuated without contact, and a smartphone service*2 that allows users to operate elevators without touching surfaces for a clean, comfortable ride. The elevator system also provides announcements in four languages even in emergencies, offering overseas visitors peace of mind.
The "connect with buildings" function contributes to BCP through its multiple power source function that enables the elevators to receive power from solar power generation systems and electric vehicles. The elevators can connect to service robots that perform security, cleaning and transport services via our IoT platform "Ville-feuille"*3 to achieve manpower savings and to prevent congestion.
The "connect with the city" function achieves integrated management of elevators and building facilities across multiple buildings by connecting with the building integration solution "BuilUnity"*4. We also have debuted a larger seven-person elevator size that can comfortably transport a wheelchair to support barrier-free access.
Circulating fan equipped with the Health Air® function: The elevator car is kept comfortable continuously with the Health Air® function, which creates a curtain-like electric field and discharge space to control various airborne substances, and a deodorizing filter.
Contactless elevator buttons:
Register the elevator call by raising your hand to the button without contact
The buttons in the elevator car and hall now have anti-viral, anti-bacterial properties. You can use the elevators with greater peace of mind knowing that all parts you may touch are anti-viral and anti-bacterial.
Using a dedicated smartphone app, you can now automatically call for an elevator without using your hands and automatically register the floor you are headed to. Smartphone linkage makes our elevators more convenient and comfortable than ever before.
Provides service in multiple languages:
To offer a sense of security to non-Japanese speaking users, announcements and indicators come in multiple languages. Emergency indicators are available in four languages, namely Japanese, English, Chinese, and Korean, and in two languages during ordinary times.
Adaptable to multiple power sources:
The system is compatible with various power sources even if power supply is interrupted in an emergency. In addition to use of the included battery, the elevator can be operated at lower speed using power from solar power generation systems and electric vehicles (V2H).
Elevator for India
The NEXIEZ Series, a line of standardized elevators for international markets use a gearless traction machine equipped with a permanent magnet motor. This results in a more compact, lightweight design and a 20% reduction in power consumption compared to conventional models. Further reductions in power consumption can be achieved by installing LED interior lighting and a converter system that stores and uses electricity generated during braking. For Europe, where people are very environmentally conscious, we have introduced MOVE, which saves space and reduces the burden on the environment for low- to medium-rise office buildings and condominiums. NEXIEZ-LITE for India, where power outages occur often, we provide a function that automatically checks the elevator conditions and swiftly lands the elevator car at the nearest floor using a battery in the event passengers are confined in the car due to a power outage as a standard function to support the needs of local users.
Our elevators have built-in disaster prevention functions in case of various disasters, including earthquakes, fires and flooding due to heavy rain. For example, in the event of an earthquake, when a sensor detects the first tremor (P-waves) or when a large quake is forecast based on earthquake early warnings distributed by the Japan Meteorological Agency, the cars will park at the nearest floor to reduce the risk of passengers becoming trapped inside. Additionally, ELE-Quick is included in the elevator maintenance menu. This diagnosis/recovery system enables an elevator to automatically determine whether or not there is any anomaly after it is stopped by the earthquake emergency operation system. When it is determined that operation is safe, elevator service resumes, and elevators are put back in use quicker than conventional systems.
When elevator passengers pass through a security gate, their destination floors are automatically registered in the system based on security information stored in their ID card, such as an employee card. Furthermore, passengers are advised as to which elevator to board on a display at the security gate. This eliminates the need to press buttons in the elevator hall or inside the elevator car. It also minimizes stops by assembling passengers into a single car according to their destination floors. Boarding times can be shortened during rush hours, such as the beginning of office hours, and transport efficiency is improved. As a result, congestion in the elevator hall is eased.
ELE FIRST-i plus is a preventive maintenance service provided by Mitsubishi Electric Building Techno-Service Co., Ltd. A remote inspection system checks equipment during normal operation 24/7, 365 days a year, and if it finds any "modulation" leading to failure, the company’s information center is alerted. Technicians then conduct a detailed onsite inspection, and maintenance is carried out after narrowing down the check points utilizing data provided by the monitoring system.
If one or more passengers is trapped in an elevator car, the system automatically alerts the information center and analyzes the status of the elevator. When remote rescue is deemed possible, the staff confirms the situation by communicating with passengers via an intercom transceiver and camera mounted inside the elevator car. A rescue attempt is then made via remote access, while technicians are simultaneously dispatched to the site.
Furthermore, the smartphone service, which is available as an option under a separate contract, enables users to set their destination floor via a dedicated app in advance so that they can operate the elevator without touching the buttons in the waiting area or inside the elevator car.
ELE FIRST-i plus
In the growing global elevator market, the need for user convenience and comfort as well as safety is increasing, and the importance of maintenance services supporting such needs are attracting attention.

To maintain the safety, security and comfort of elevators, renewal at appropriate times*1 is essential. The Elemotion+ menu facilitates the renewal of existing rope-type elevators to the latest model equipped with an inverter-controlled system, a gearless traction machine and permanent magnet motor. With the adoption of a system to protect elevators from moving with the door opened*2 and devices in accordance with the latest seismic criteria, this menu provides safe, secure, smooth and comfortable rides. Moreover, Elemotion+ offers a variety of replacement equipment, enabling customers to make decisions based on budget, preferred installation time, and the ability to reduce waste.
The addition of Elemotion+ [ZERO] has made it possible to conduct renewal work with zero days of consecutive elevator stoppage. We are promoting elevator renewals by making it easy for customers to plan renewal work.
To maintain the safety and security of escalators as well, renewal at appropriate times* is necessary. A renewal of escalators to a model with an inverter system facilitated by the Esmotion+ menu provides them with the latest safety measures that allow the escalators to be used with a sense of security. When the safety system is in operation or the emergency switch is pressed, the escalator stops slowly to reduce the risk of passengers stumbling or falling. However, when the escalator detects an object caught in the escalator, it stops the escalator immediately. By stopping the escalator slowly or immediately depending on the situation in this way, safety during emergencies has been improved. The inverter system, which enables the speed to be switched to a slow speed for senior citizens and children to get on and off easily, also considers the safety of users.
