Stacking type High Speed Doors specially for big size
Stacking lifting up rapid doors, with high wind resistance. Such doors are specially for external use big size openings larger than 6m wide * 6m high
Rapid Roller Door is a type of automatic roll up door that is designed to open and close very quickly, widely used in modern factories and warehouses. It can run in high speed and frequency, very fit for areas with heavy traffic. It improves efficiency of material handling. On the other hand, air flow and heat conduction through the door is reduced obviously, to keep clean, hygiene and temperature inside room. Automatic running is realized with programmed control system and sensors.
High speed running
The opening speed can reaches up to1.0m/s. And the closing speed can reaches up to 0.8m/s. This means that the door can finish a cycle of opening and closing within in
several seconds. It bring several major benefits:
Improve work efficiency:
Workers or forklifts will no need wait in front of the door and can directly go across it. The material handling speed is higher by at least 5 times
than tradional roll up doors;
Keep clean and hygiene:
The fast running reduces the open time to only seconds in a cycle of passing the door.
Thus much less outside air and dust will enter the room;
Keep temperature:
Heat loss is reduced by large by reducing open time.
High frequency working
The motor is frequency motor, and control panel is frequency inverter system. It can
change work power output gently. So the door can start and stop in a soft process. Its
running speed will accelerate or decelerate gradually. This can avoid overriding and
over-heating caused by constant up and down. So the door can keep running and no
need worry its motor burnt or structure damaged.
Our door can run up to1000 times per day. This is why it is a best choice for busy area with heavy traffic like forklifts or passing workers. This is why it is a best choice for busy area
with heavy traffic like forklifts or passing workers.
Heavy duty wind resistance
Strong solid aluminum bar is used as wind bar to support door curtain. Even there is big pressure on the door
curtain, it will not get out of side rail easily like regular fabric doors. Thus the door can resist big wind pressure,
up to 110km/h which is rated is Europe grade III . And its size can be as big as 10m wide and 8m high.
Such doors are widely used in mine industry, big machinery factory, and garbage disposal plant where big size
openings are needed.
Longer work life with lower maintenance
Advanced Italy servo technology drive motor and control system. Compared with
traditional door system in the market, it has several advantages:
Double encoders:
They calibrate with each other, to make running limit more accurate than tradtional
limit sensors. This completely avoid running limits error and reduce maintenance.
And even if one encoder is damaged, you can switch to another encoder and the door wil l continue to work well, no need repair;
Absolute encoder:
outside encoder is advanced absolute encoder. It will always keep the set limits
even during power failure. So you no need bother to do the frequent job of
re-seting the limits;
Flexile Torque Control System:
The output torque of motor keeps changing according to running speed and load
automaticlaly. This avoid over-heating and over-load after long time use, and make
sure the door work longer life.
User freindly Human-machine interface system
There is a LED display on the controller, showing all parameters and setting steps in
English language. You can set or change any parameters like using a mobile phone. So
you will feel very easy and comfortable to use the doors even you do not have any
experience.
And it is inbuilt with Fault-shooting program. The display will show the error information
when there is some problem. There are addtional input and output signals in the controller. You can activate it by the screeen and the door will work together with your production line, robots, conveyor, or other machines.
Various Colors
We supply six different colors for your choice. You can make a free selection among
them. Our doors can integrate into your whole building design and make the building
harmony and beautiful.
Blue, Yellow, Orange, Grey, White, Full clear
A transparent window can be made at human ey height. This makes it easy to see what is
happening at another side of the door. It will be more safe for a busy area with moving workers and forklifts or other vehicles.
Multiple safety protection
Considering the high speed running of the door, safety protection become very important to avoid possible accidents. This can not be neglected when using such high performance
doors. There are three safety protection devices:
Safety photo sensor:
The sensor can send a infrared light beam from one side to another. When it is blocked by passing human or vehicles, the door will immediately stop or get up. Thus it aims to avoid
accident;
Safety airbag sensor:
It is a soft rubber airbag at the bottom. If somethingtouches the bottom, the door will stop
or get up. So it aims to stop accident once it happens;
Alarm lamp:
It gives out light flash signal or sound signal when the door running. Passing workers or
vehicles can easily get aware that the door is working and take special care to avoid
accidents.
Interlocking Function
In some industries like food, pharmaceutical or electronics, it is a very important issue to keep hygiene and clean inside the room. This is critical to keep final quality level of the
finished products, no matter it is food, medicine or electronic applicances. How to
prevent outside air and dust is a major difficulty. A interlocking passage system can solve this problem perfect. Door A and Door B are installed at two ends of the passage.
When door A opens, Door B will never open. Only after Door A closed, Door B can
open.Thus, at any time, there is at least one door keep closed. So the outside air and
dust will never be able to enter the room.
We have input the interlocking function in every door. When necessary, any two doors
can be interlocked.
Various Operation Methods
Every door will have wall mounted control buttons at both interior and exterior. This can make sure the door can be operated by workers at any time when they need.
To improve your work efficiency, we also offer various addtional choices of operation devices.
Remote control:
Each door can have two or more remote control units. People can open or close the door from as far as 100m distance;
Radar sensor:
It can detect human or vehicles moving towards the door, and the door will open automatically. After passing through, the door will close automatically within several seconds which can set;
Vechicle loop detector:
It detecting wire loop will be embedded into ground floor near the door. It can detect all the big metal objects passing on its loop like forklifts. It does not detect humans. Thus such sensor is quite fit for doors which only allow forklifts passing automatically.
Pull-cord switch:
This is very convinient for forklift drivers, and also can avoid unnecessary opening of the doors compared with radar sensors or vehicle detector;
