Both fast running and high strength. It can be used as exteral security doors with heavy traffic and also need to prevent outside people. It can also be used as thermal insulated rapid doors fit for temperature-controlled rooms.
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:
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;
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 workers.
Thermal insulated and high strength
The door slat is made from double skin aluminum sheet filled with high density PU foam. Total thickness reaches 43mm.
Good thermal insulation:
Special cold-bridge design, cutting off the heat transmission route. It can help keep temperature inside the room;
benefiting from its aluminum material and reinforcing curving design, the door can windstand wind up to 120km/h;
it can prevent outside people and protect the warehouse from theft and robbery.
Our guide rail is a Archimedes spiral. It is the line of points corresponding to the locations over time of a point moving away from a fixed point with a constant speed along a line that rotates with constant angular velocity.
With such a spiral guide rail, our doors can move very smooth in a constant speed. This reduces the friction and obstruction during coiling and improves the work life.
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;
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.
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.
①Grey, ② Red, ③ Orange, ④ Champagne,
⑤ Yellow, ⑥ White, ⑦ Blue, ⑧ Silver, ⑨ Coffee
Transparent windows can be made at human eye height. Its material is polycarbonate window with ultroviolet sunlight-resist. 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 something touches the bottom, the door will stop or 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 accidents.
Various shape to fit your project site
In some cases, you may find it difficult to install a standard spiral door in your area. The ceiling is not high enough, or there are some objects like water pipe or cable tubes passing by. There is not enough head rom to place the top body. To solve this problem, we expand the design of guide rails, and offer three options.
Archimedes spiral, first choice, for enough top space;
for limited space but above 500mm space
for very limited top space less than 500mm;
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;
