When the power failure causes the passengers being trapped in the elevator, the device automatically switches to the emergency operation. The elevator will stop on the nearest level with the battery and automatically open the door to release trapped passengers.
Safety supervision system in elevator
Each maintenance service network station of United Elevator makes real-time supervision over elevator in operation through reserved intelligent system interface (remote supervision interface); exclude malfunction before occurrence to guarantee 24-hour and 365-day safe and reliable operation of elevator.
New generation of advanced control system
32-bit industrial ARM controller with high level of performance; precise speed signal with outstanding comfort;
Combine all digital vectors inverter, make self-diagnosis and record through feedback to ensure efficiency and safety of elevator;
Perfect safety protection measures, be able to find emergencies and make corresponding protective measures when there is emergency arising to ensure safe and reliable operation;
Strong anti-electromagnetic interference ability, strong antistatic electricity ability.
Digital converter technology
Make adjustment over current and phase according to practical load and speed of lift car, Make real-time and precise control over driving force of main machine to ensure safe and stable elevator operation.
Intelligent management system
IC card intelligent recognition system and authority management function achieves perfect combination of elevator control technology and computer communication technology, which greatly strengthen the security and intelligence of building management.
Permanent magnet synchronous gearlesssystem
Low heat loss and minimum operation cost, work efficiency is as high as 95%, 40% of energy saving compare with conventional technology. At the same time without the need for complex lubrication system, completely solved the problem of environmental pollution caused by the leakage of the traditional machine, and met the requirement of non-maintenance of motor and environmental protection.
Energy feedback device
Collect and store electric energy of no-load operation of elevator and then make feedback to elevator (electric mode) for use, saving more than 60% energy for elevator.
LED automatic illumination system
Adopt LED lamp, saving more than 85% energy compared with traditional incandescent light bulb and fluorescent lamp; at the meantime, after certain period with no call and waiting command, the illumination inside lift car will be automatically turned off, reaching the purpose of energy conservation.
United passenger elevator lift utilizes the advanced lift control technology, which is advanced variable frequency variable voltage (VVVF) drive combined with fully computer control technology with the data net system and modularized structure.
It brings a more precise, efficient, flexible and reasonable systematic controlling. It also adopts the most effective self-inspection program to give a full play of the lift functions. It moves the lift performance to a higher level. Truly satisfies the passengers’ requirement.
Name of Product: ISO 9001 approved VVVF passenger elevator from manufacture

Passenger Elevator Function
1. VVVF Drive
Motor rotating speed can be precisely adjusted to get smooth speed curve in elevator start, travel and stop, and gain the sound comfort
2. VVVF door operator
Motor rotating speed can be precisely adjusted to get more gentle and sensitive door machine start /stop
3. Independent running
The elevator can not respond to hall calling, but only respond to the command inside the car through the action switch
4. Automatic pass without stop
When the car is crowded with the passengers or the load is close to preset value, the car will automatically pass the calling landing in order to keep maximum travel efficiency
5. Automatically adjust door opening time
Door opening time can be automatically adjusted according to the difference between landing calling and car calling
6. Reopen with hall call
In the door shutting process, press reopen with hall call button can restart the door
7. Express door closing
When the elevator stops and opens the door, press door-shut button, the door will be closed immediately
8. Car stops and door open
The elevator decelerates and levels, the door only opens after the elevator comes to a complete stop
9. Car arrival gong
Arrival gong in the car top announces that the passengers arrive
10. Direct parking
It completely accords with distance principle with no crawling in the leveling. It greatly enhances the travel efficiency
11. Command register cancel
If you press the wrong floor command button in the car, twice continuous pressing of
same button can cancel the registered command
1. Photocell protection
In the door open and shut period, infrared light that covers the whole door height is used to probe the passengers and objects.
2. Designated stop
If the elevator can not open the door in the destination floor out of some reason, the elevator will close the door and travel to the next designated floor.
3. Overload holding stop
When the car is overload, the buzzer rings and stops the elevator in the same floor
4. Anti-stall timer protection
The elevator stops operation due to slippery traction wire rope.
5. Start protection control
If the elevator does not leave door zone with in the designated time after it gets started, it will stop the operation.
6. Inspection operation
When the elevator enters into inspection operation, the car travels at inching running.
7. Fault self-diagnosis
The controller can record 62 latest troubles so as to quickly remove the trouble and restore the elevator operation.
8. Repeated door closing
If the elevator can not close the door due to certain obstacle or interference, the elevator will reopen or re-shut the door until sundries are eliminated.
9. Up/down over-run and final limit protection
The device can effectively prevent the elevator from surging to the top or knocking the bottom when it is out of control. It results in more safe and reliable elevator travel.
10. Down over-speed protection device
When the elevator downs 1.3 times higher than the rated speed, this device will automatically cut off control mains, stop the motor running. Safety tongs act to force the elevator stop in order to ensure the safety.
11. Upward over-speed protection device
When the elevator up speed is 1.3 times higher than rated speed, the device will automatically decelerate or brake the elevator.
