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.

・Disaster Prevention Functions

Mitsubishi Electric’s 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.

・ELE NAVI Security-linked Elevator Destination Forecast System

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.

Supporting Safe and Comfortable Use of Elevators and Escalators with Maintenance Services

・ELE FIRST - smart Remote Maintenance Service

ELE FIRST - smart (compatible with AXIEZ-LINKs Mitsubishi machine-room-less elevator) accumulates daily elevator operation data and predicts the aging of equipment through machine learning to allow for maintenance to be performed at optimal timing. It also further promotes the prompt rescue of passengers trapped in an elevator car, and early recovery in the event of an earthquake based on the automatic diagnosis function, along with other benefits. Its services provide optimal information and functions to improve convenience for the elevator owner in maintenance and management, as well as convenience for elevator users (through smartphone services, etc.). These services realize an elevator that will not stop or be stopped and an elevator that can be connected to at any time.

In the event of one or more passengers being trapped in an elevator car, the system’s service for the remote rescue of trapped passengers automatically alerts the information center and analyzes the status of the elevator. If remote rescue is deemed to be possible, the staff members confirm 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.
The ELE-Quick diagnosis/recovery system allows for the elevator to automatically determine whether or not there are any anomalies after the earthquake emergency operation system stops it. Once it is determined that operation is safe, elevator service resumes, meaning that elevators can go back into use quicker than conventional systems.
Furthermore, the smartphone service allows 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.

  • * Using this service requires a contract with Mitsubishi Electric Building Solutions Corporation.

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.

  • *1 25 years after completion of a building is regarded as an indication for renewal.
  • *2 A system to prevent elevators from traveling with the door open even in the event of abnormalities in the control circuit or brake.

・Esmotion+ Escalator Renewal Menu

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.

  • * 25 years after completion of a building is regarded as an indication for renewal.
