Drive Type: AC Traction Control System: Computerised single speed control Traction Machine: Nonsynchronous worm gear driven
United dumbwaiter elevator is small and flexible with simple structure, it can easily merge in buildings and provide fast, economical and practical small cargo transportation service in hotels, restaurants, banks, houses, libraries.
Saving space, realize perfect economic transmission.
Small space possessed, no need for strong civil capacity, designed for providing vertical transmission for food and small goods, which is secure and practical, flexible for operation and easy for maintenance, be able to achieve perfect and economic design for new and old buildings.
Diversified car design
Variety of car design, material can be freely chosen for customers, to the greatest extent of satisfying individual selection of architectural style and architectural quality.
• only need small space, the concrete shaft is no longer necessary. our compact steel frame make it possible
• without concerning the building is old or new.
• the use of advanced computer control module assures the stable running and accurate landing
• humane design makes the operation simple and reliable
•easy to conduct the maintenance work

New generation landing door device
United elevator firstly apply the new generation landing door device in the indurstry.which prevent safety lock from slippery, landing door bump, landing door unusual opening. The three new safety standards redefine the safety.
The screen door protection system
Form light barrier in the elevator door with 194 infrared beam protection, it can make sensitive response to any person or object accessing in its detection plane with high security performance.
Emergency stop device
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.
