Introduction
In modern buildings, rolling doors are a common door system and are widely used in shops, warehouses, garages and other places. According to different driving methods, rolling doors can be divided into electric rolling doors and manual rolling doors. With the development of science and technology and the improvement of people’s living standards, electric rolling doors have gradually gained popularity due to their convenience and efficiency, but manual rolling doors still play an important role in some specific scenarios. This article will explore the differences in maintenance between electric rolling doors and manual rolling doors from multiple dimensions to help users better understand and choose the type of rolling door that suits them.

Maintenance points of electric rolling doors

Daily maintenance
Daily maintenance of electric rolling doors mainly includes the following aspects:
Cleaning and inspection: Clean the door body, track and motor surface regularly to ensure that there is no dust and debris accumulation. Check whether the door body has deformation, cracks or other signs of damage.
Lubrication and maintenance: Lubricate the motor, drive chain and guide rail regularly to reduce friction and wear. Special lubricating oil or grease can be used.
Electrical system inspection: Check whether electrical components such as power lines, remote controls, controllers and sensors are working properly. Make sure that the remote control battery is fully charged and the signal transmission is stable.
Travel switch adjustment: Regularly check the position of the upper and lower travel switches to ensure that the door body can stop accurately when opening and closing to avoid hitting the top or bottom.
Manual release function test: Regularly test the manual release function to ensure that the door body can be manually operated smoothly in the event of power failure or emergency.

Fault repair
The fault repair of electric rolling shutter doors is relatively complicated and usually requires professional personnel to handle. Common faults and repair methods include:
Motor failure: The motor does not rotate or makes abnormal sounds, which may be due to motor overheating, bearing damage or power supply problems. It is necessary to check the heat dissipation of the motor, power supply voltage and wiring.
Remote control failure: The remote control cannot control the door body, which may be due to low battery, signal interference or receiver failure. You can try to replace the battery, clean the contact points of the remote control and receiver, or re-pair the remote control.
Sensor failure: Failure of the photoelectric sensor or safety eye may cause the door body to fail to close or open normally. It is necessary to check the installation position, line connection and sensing distance of the sensor.
Track jam: Foreign objects or deformation in the track may cause the door body to run poorly. It is necessary to clean the debris in the track and check the flatness of the track and the balance of the door body.
Control board failure: Damage to components on the control board or program errors may cause abnormal operation of the door body. Professionals are required to detect and repair, and the control board may need to be replaced.

Safety maintenance
Electric rolling shutter doors are usually equipped with a variety of safety functions, such as anti-pinch function, automatic reverse function, and power-off manual release function. In order to ensure the normal operation of these safety functions, the following maintenance needs to be performed regularly:
Anti-pinch function test: Regularly test the anti-pinch function to ensure that the door body can automatically stop or reverse when encountering obstacles.
Emergency stop button check: Check whether the emergency stop button is sensitive to ensure that the door body can be stopped in time in an emergency.
Manual release function check: Regularly test the manual release function to ensure that the door body can be manually operated smoothly in power failure or emergency situations.
Safety eye calibration: Check whether the safety eye of the photoelectric sensor is calibrated correctly to ensure that it can accurately sense obstacles.

Maintenance points for manual rolling shutter doors

Daily maintenance
Daily maintenance of manual rolling shutter doors is relatively simple, mainly including the following aspects:
Cleaning and inspection: Clean the door body and track regularly to ensure that there is no dust and debris accumulation. Check whether the door body is deformed, cracked or otherwise damaged.
Lubrication and maintenance: Lubricate the reel, pull rope and guide rail regularly to reduce friction and wear. General lubricating oil can be used.
Pull rope inspection: Check whether the pull rope is worn, broken or loose. If necessary, replace the pull rope in time.
Spring inspection: Check whether the spring is loose or damaged. The elastic force of the spring directly affects the balance of the door body and the smoothness of operation.
Lock inspection: Check whether the door lock can be opened and closed normally, and whether the key can be inserted and turned smoothly. If necessary, replace the door lock or key.

Fault repair
The fault repair of manual rolling shutter doors is relatively simple and can usually be handled by the user. Common faults and repair methods include:
Pull rope breakage: Pull rope breakage is one of the common faults of manual rolling shutter doors. You can replace the new pull rope and ensure that it is firmly installed.
Damaged spring: A loose or broken spring can cause the door to be unbalanced or unable to close properly. The spring needs to be replaced and installed correctly.
Track jam: Foreign matter or deformation in the track may cause the door to run poorly. It is necessary to clean the debris in the track and check the flatness of the track and the balance of the door.
Deformed curtain: Deformed curtain may cause the door to be unable to roll up or down normally. You can try to correct the deformed curtain, and replace the curtain in severe cases.
Door lock failure: The door lock cannot be opened and closed normally or the key cannot be inserted, which may be due to rust or damage to the lock core. You can use lubricating oil to lubricate the lock core, or replace the door lock.

Safety maintenance
The safety maintenance of manual rolling shutter doors mainly includes the following aspects:
Operation specification: When operating a manual rolling shutter door, make sure to follow the correct steps to avoid excessive force or improper operation that may cause damage to the door or personal injury.
Lock safety: Make sure the door lock can work properly to prevent unauthorized entry. If necessary, upgrade to a safer lock.
Regular inspection: Regularly check the integrity of the door body and components to promptly discover and deal with potential safety hazards.
