Common Malfunctions and Repairs of Rapid Roll Up Doors
Rapid roll up doors are widely used in industrial premises due to their efficiency and durability. However, like all mechanical systems, rapid roll doors may also fail in the process of use. In this article, we will introduce in detail the common types of faults, causes and effective repair methods to help enterprises better maintain the equipment, to ensure normal operation.
Common Malfunctions of Rapid Roll Up Doors
1. Rapid shutter door won’t start or work
Wiring inside the motor is aged or short-circuited.
The transmission belt between the electric motor and the rolling door falls off or breaks.
The rolling shutter door is stuck by foreign objects and cannot be lifted normally.
The control switch of the electric motor is faulty, resulting in the signal not being transmitted.
2. Collision sound when the door closes
Closing speed is too fast.
Fault inside the electric motor.
Switching speed too slow
Possible cause:
Abnormal motor voltage.
3. Shaking and harsh sound during operation
There is debris in the door track that prevents the pulleys from operating properly.
4. Door opens and closes automatically when not in operation
Sensor malfunction.
The sensor is interfered by other objects and cannot receive the signal properly.
Repair Methods for Rapid Roll Up Doors
Door Fails to Start or Operates Slowly
- Check the motor for proper functionality. Replace it if necessary.
- Inspect mechanical components for obstructions. Ensure that the rollers and drive mechanisms are lubricated at least once a year.
- Inspect and adjust the transmission belt annually. Regularly check all parts for wear and tear.
Controller Malfunctions
- Replace the power contactor and drive gear as needed.
- If the motor produces excessive vibration or noise, check for worn-out bearings and replace them. Add lubricant to the rollers and inspect the motor’s condition.
Track and Sensor Maintenance
- Remove debris from the tracks to ensure smooth roller movement.
- Calibrate or replace sensors that are malfunctioning or being interfered with by external objects.
General Preventive Maintenance
- Schedule regular inspections for all moving parts, including motors, belts, and sensors.
- Apply lubrication to key components to reduce friction and extend the lifespan of the door.
- Train staff on the proper operation of high-speed doors to minimize user-related damage.
Why Regular Maintenance Is Important
Rapid shutter doors are essential equipment for improving efficiency in industrial locations such as logistics, manufacturing and warehousing. Regular maintenance and timely repairs not only ensure optimum performance, but also avoid downtime and costly replacements.
Conclusion
Understanding the common faults and repair methods of rapid roller doors can effectively improve the performance and service life of the equipment. With proactive maintenance and timely repairs can keep their workplaces safe and productive.
