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
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
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
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
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
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
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.
