High pole lights are large-scale lighting facilities for urban roads, sports stadiums, airports, ports, and docks. So how do we maintain them on a daily basis?
　

1. Check the anti-corrosion situation： Regular inspection of anti-corrosion conditions is to ensure that the metal components of high pole lighting facilities are not affected by corrosion, and to maintain the stability and safety of the structure. The quality of hot-dip galvanized anti-corrosion coating in accordance with relevant standards is the key to ensuring long-term use of facilities. When problems are found, they should be repaired or repainted with anti-corrosion coating in a timely manner.

2. Check verticality： Maintaining the verticality of the lamp post is an important factor in ensuring lighting effectiveness and safety. By using a theodolite for measurement and testing, ensure that the verticality of the lamp post meets the specified standards, and avoid tilting that may cause instability or safety hazards to the facilities.

3. Inspect the outer surface and welds： Regular inspection of the outer surface and welds of the lamp post for rust, as well as the quality of the welds, is crucial to ensuring the integrity and safety of the facility structure. Using methods such as ultrasonic and magnetic particle testing to inspect welds, promptly identifying and addressing issues.

4. Check the mechanical strength of the lamp panel： The mechanical strength of the lamp panel is directly related to its safe use, especially the heat dissipation of enclosed lamp panels that require special attention. Ensure that the structure of the lamp panel is complete and the mechanical strength meets the requirements to avoid safety hazards caused by damage to the lighting fixtures.

5. Check the lamp bracket and wires： The fastening bolts of the lamp bracket need to be checked regularly, and the projection direction of the lamp should be adjusted to ensure the lighting effect. At the same time, check the usage of the wires inside the lamp panel to ensure that there are no safety hazards such as aging, cracking, or exposed wires, and promptly handle any unsafe phenomena.

6. Replace and repair components： Replacing and repairing damaged components such as light sources and appliances is an important step in ensuring the normal operation of facilities and can prevent safety issues caused by component failures.

7. Check the lifting transmission system： The safety and reliability of the lifting transmission system are crucial for the use of facilities. Thoroughly inspect both manual and electric functions to ensure flexible transmission, smooth lifting, and safe reliability of the mechanism. Pay special attention to key components such as brake motors and limit devices to ensure their normal operation and safety performance.

8. Inspect power distribution and control equipment： The connection between power distribution lines and control equipment is firm and reliable, and the functions of three-phase load balancing and midnight light control operate normally to ensure the electrical safety performance of the facilities.

9. Electrical safety performance inspection： Check the insulation resistance between the power supply incoming line and the ground to ensure that the safety performance of the electrical system meets the requirements and avoid safety hazards caused by electrical faults.

10. Inspection of protective grounding and lightning protection devices： Ensure that the protective grounding of metal lamp posts and electrical equipment metal casings is good, avoiding safety issues caused by weather factors such as lightning strikes.

11. Measure the plane of the basic panel： By measuring the plane of the foundation panel with a spirit level, combined with the inspection results of the verticality of the lamp post, analyze the settlement of the foundation, and make corresponding measures in a timely manner to ensure the stability and safety of the facilities.

12. Regular on-site testing of lighting effects： Finally, regular on-site testing of lighting effects is carried out to ensure the normal operation of high pole lights and the required lighting effects.
