Fire Truck Aluminum Alloy Roller Door Manufacturer Explains the Working Principle of Roller Doors
Roller shutters are primarily composed of the door body, the drive unit, and the control system. The door body is made from stainless steel and aluminum alloy profiles, hinged using the parallelogram principle for flexible expansion and contraction with a large travel range. The drive unit is powered by a special motor, featuring worm gear reduction, and is equipped with a manual clutch for manual opening and closing during power outages. The control system includes a control panel, button switches, and can be fitted with a wireless remote control device upon customer request. It can also be equipped with a scrolling display screen that can show up to 500 characters of content. Additionally, it can be fitted with an intelligent infrared dual-probe collision avoidance device, which can automatically return to operation when encountering people or foreign objects within 20-30 cm, ensuring the safety of vehicles and pedestrians.
