Quick Roller Shutter
Safety Device of Quick Roller Shutter
The quick door safety system is a mounting protection device other than the brake system. A pneumatic safety device is installed 25CM below the left and right guide rail or at the bottom of the door rail. When the door encounters a vehicle or a pedestrian during the closing process, the quick door will automatically stop and then run up to the fully open position. When the photoelectric system and airbags fail, they should be repaired or replaced in time; otherwise it will easily cause pedestrians and vehicles to be injured because of the speed.
Power and Braking System:
The power and braking system of the motor is the key component of the overall quick roller shutter, and it is the guarantee for the safe, efficient and smooth operation of the whole quick door. When the brake system fails, it must be repaired and replaced in time;
Control and Switch System:
The control and switch system is composed of main components such as fast door output, shutdown, signal conversion, and programming. It is divided into integrated circuit board control chip and independent electrical components. The electronic components have high requirements on the application environment. In order to ensure efficient and safe operation of the quick door, the product maintenance should be carried out frequently during daily use. When the control system fails, it must be replaced and repaired in time;
Such as steel structure, wind-resistant device, sealing device, roller shutter structure, interlocking device, emergency stop device, roller, limit device, switch device etc. are all inseparable systems. Maintenance is of paramount importance to ensure the normal operation of all systems.
