Design conditions
- Wind resistance level: The standard wind pressure is 55kg/㎡, with a safety factor of 1.4, which means the maximum design wind pressure is 77kg/㎡.
- Rising speed: 6 meters per minute (approximately, speed depends on door size)
- The cord fabric has anti-aging and abrasion resistance
- The overall sealing performance of the door is good
- Double layer curtain insulation
Design scheme
- The main principle of pulling the door curtain up
- The traditional technique for using this type of door is the parallel horizontal double-layer stacking of segmented door curtains, with a total distance of approximately 300mm-700mm between the two door curtains
- Composition of door curtains
- The door curtain is composed of double-sided industrial belts (high polymer fiber biaxial woven fabric and PVC coated composite) and ribs; The ribs can be composed of steel frame structural beams and aluminum profile fasteners.
- This combination can ensure the wind resistance strength requirements of the door curtain under strong wind conditions, while reducing the weight of the door curtain, making it easy to operate. The principle of wind resistance is that the wind passes from the door curtain to the ribs, and then from the ribs to the building steel structure and ground.
Power system
The power system consists of a set of motors, reducers, and braking systems, and will use a dedicated motor for flexible doors.
Control system
The control system consists of a motor control system and a motor overload protection system, all of which are integrated into one control box.
Security system
During the opening process or power outage, the braking system in the power system provides sufficient braking force to prevent the door curtain from slipping off on its own under any circumstances. The safety system of the sling has a strength of 5 times, and in the event of a sling breakage, it is equipped with an automatic hook anti fall system to effectively prevent the door from falling.
Sealing system
- In order to effectively ensure the integrity of the sealing system, a brush seal is used between the door curtain and the sliding door cylinder.
- The main advantages of this product
- The system is safe and reliable, and in the event of a sling breakage, an anti fall protection system is used to prevent the door from falling.b) Adopting a dual wind resistant system.
- Adopting a multi-point lifting system.
Safety & Protection: Multi-Layered Safeguards
Anti-Pinch & Obstacle Detection: Standard safety features include:
Infrared photoelectric sensors: Mounted on door sides or below, they stop the door from closing and trigger it to rise if an obstacle (person, cargo, or object) is detected.
Emergency stop & overload protection: The motor automatically shuts down if overloaded, and an emergency button cuts power to halt operation in crises.
