Safety device of the rolling door be maintained

 

The maintenance frequency of the rolling door safety device can be determined based on factors such as frequency of use and environment. Generally, it is recommended that:

1. Highly frequently used rolling shutter doors

If the rolling door is opened and closed frequently every day, such as rolling doors in commercial shops, logistics warehouses, etc., it is best to maintain the safety device every 1 to 3 months.

Monthly inspection:

To check the sensitivity of the resistance rebound device, you can touch the door body with a soft object when the door is descending, and observe whether the door can stop in time and rebound.

Check the safety bottom edge for wear, deformation or looseness to ensure it can trigger the safety function normally.

Check whether the position of the limit switch is accurate and whether the door can stop accurately when it reaches the upper and lower limits.

Every two to three months:

Tighten the connection parts of the safety device, such as screws, rivets, etc., to prevent loosening due to vibration or long-term use.

Clean the dust and debris on the surface of the safety device to avoid affecting its normal operation. You can wipe it gently with a clean soft cloth.

Check the electrical part of the safety device, such as whether the sensor circuit is intact, damaged or has poor contact.

2. Rolling shutter doors used at medium and low frequencies

For places with relatively low frequency of use, such as some small warehouses and garages, the safety device can be maintained every 3 to 6 months.

Check every three months:

Perform monthly inspections similar to those for high-frequency roll-up doors, but less frequently.

Observe the overall operation of the safety device to see if there are any abnormalities, such as freezing or delayed response.

Every four to six months:

Carry out a more comprehensive inspection and maintenance of the safety device, including checking whether the internal mechanical structure is normal and whether there are any worn or damaged parts.

If necessary, the safety device can be lubricated by applying a suitable lubricant to the moving parts to ensure smooth operation.

3. Insulated Roller Shutters in special environments

If the rolling door is in a special environment, such as humid, dusty, high or low temperature, the maintenance frequency should be appropriately increased.

Wet Environment:

Since moisture can easily cause rust on metal parts and electrical failures, safety devices should be maintained every 1 to 2 months.

Focus on checking the rust condition of metal parts and carry out rust removal and protective treatment in time.

Make sure the electrical parts are well waterproofed and use moisture-proofing agent or sealant if necessary.

Dusty Environment:

Dust may affect the sensitivity and smooth operation of the safety device, so maintenance should be performed every 2 to 3 months.

Clean the dust on the safety device regularly. You can use compressed air or a vacuum cleaner to clean it.

Check whether the sensor and other components are blocked by dust, and clean or replace them if necessary.

High or low temperature environment:

Extreme temperatures may affect the performance and life of safety devices; perform maintenance every 2 to 4 months.

In high temperature environments, check the heat dissipation of safety devices to ensure that they are not damaged by overheating.

In low temperature environments, check the cold resistance of safety devices to prevent malfunctions due to low temperatures.

The maintenance frequency of the rolling door safety device should be adjusted according to the actual situation to ensure that it is always in good working condition and protect the safety of personnel and property. At the same time, if any abnormality is found in the safety device during use, it should be inspected and repaired immediately.
