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 to 2.0m/s. And the closing speed can reaches
up to 1.0m/s. This means that the door can finish a cycle of opening and closing within in
several seconds. It bring several major benefits:
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;
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;
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 to 2000 times per day. This is why it is a best choice for busy area with heavy traffic like forklifts or passing workers. Our door can run up to 2000 times per day.
This is why it is a best choice for busy area with heavy traffic like forklifts or passing
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:
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 will continue
to work well, no need repair;
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;
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
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:
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
It is a soft rubber airbag at the bottom. If something touches the bottom, the door will stopor get up. So it aims to stop accident once it happens;
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
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
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.
Each door can have two or more remote control units. People can open or close the door from as far as 100m distance;
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.
This is very convinient for forklift drivers, and also can avoid unnecessary opening of the doors compared with radar sensors or vehicle detector;
