1. Structural Inspection
Inspect the tower's connections, guy wire fixing points, and ground stakes for looseness or corrosion. Perform anti-corrosion treatment if necessary.
Test the lifting system's functionality, including the electrical performance of the electric interface and the wear of the lifting cable.
2. Electrical System Maintenance
Clean the lens (alcohol for glass, water for plastic). Check the condition of the light bulb and bulb changer.
Measure the open-circuit voltage and load voltage. Check the control box and power output for normal operation.
3. Safety and Performance Testing
Test the resistance value of the lightning protection grounding system (≤10 ohms). Check the grounding wire for corrosion.
Simulate fault testing to test the reliability of the backup light and alarm system.
4. Sealing and Protection
Inspect the light fixture's sealing strips and tighten the sealing screws to ensure watertightness.
Apply anti-rust paint to metal parts to prevent corrosion.
Precautions:
Wear safety protective equipment when working at heights. After maintenance, parameters should be recorded and the equipment's availability for the next cycle should be assessed.
