Maintenance of aluminum rolling shutter door
- The upper end of the installation position of the aluminum rolling shutter door should have reliable fire prevention facilities. When the lower end of the roller of the rolling shutter is wrapped or suspended, a detachable movable cover must be installed. A 500×500mm detachable inspection hole must be reserved at the lower end of the rolling shutter spring for easy maintenance.
- If there is a large shake or abnormal sound during the operation of the rolling shutter, the machine should be stopped for inspection to remove debris that hinders the standard opening and closing of the door curtain.
- The rolling shutter’s door curtain and rust-prone parts should be regularly treated with anti-corrosion, paint and maintenance. Heavy or hard objects are forbidden from impacting the door surface.
- The upper limit position of the bottom beam seat of the rolling shutter must be kept at a distance of more than 200mm from the lower end of the bearing frame to ensure that there is no top collision when the brake stops.
- The rolling shutter door should have the function of stopping in position during the opening and closing process. It should not stop and continue to slide. If the sliding distance exceeds 50mm, the rolling shutter door control electrical appliances and rolling shutter machine brakes should be carefully inspected and repaired immediately until they operate normally.
- The rolling shutter machine should be regularly inspected (at least 3 times a year) during operation, sliding, transmission and other parts, and refueled in time as needed to ensure the normal use of the rolling shutter door.
- When operating the rolling shutter door, the operator must stand where he can see the operating status of the rolling shutter door. Otherwise, it is easy to cause accidents and damage.
- For all electrically controlled rolling shutter doors, the opening and closing direction must be the same as the switch box indication, especially when the power is newly connected for trial operation or the external input power is converted into a phase line, the manual device should be used to place the door curtain at 1/2 of the door opening height, and the rolling door should be opened and closed after the power is turned on until it is by the indication, and then it can be used normally, otherwise the limiter will be damaged, causing the rolling shutter to roll back or hit the top, etc., causing losses.
- The shutter door curtain and the shutter machine are prohibited from contact with acidic and alkaline solutions to prevent corrosion of the curtain surface. Therefore, we should take good care of the shutter door, just like taking care of ourselves, to extend the life of the shutter door and improve its availability.
Maintaining the aluminum roller shutter door can not only extend its service life and reduce maintenance costs but also ensure its normal operation at critical moments. Provide safe and convenient protection for our life and work. Everyone should pay attention to the maintenance of the aluminum shutter door, follow the above precautions, regularly maintain the shutter door, and keep the aluminum shutter door in good working condition.
