How to compare the verticality of the high pole light?

Tall pole light manufacturers have a variety of calibration methods for the verticality of tall pole lights, so if we are going to calibrate tall pole lights, how to calibrate their verticality, you may see tall pole lights in a city square, a school stadium or a toll booth throughout the highway. The height of the high-pole lamp is generally more than 15 meters, and the power of the lamp head is more than 150 watts, so as a high-pole lamp manufacturer, how should the high-pole lamp be calibrated?


In the actual calibration process, high-pole lamp manufacturers generally design all products with a height of more than 12 meters to be inserted in two actual poles of different lengths, that is, splicing themselves. One reason for calibration is because the height of the high-pole lamp is too long to transport, another reason is that if it is too long in actual use, it is inevitable that some ultra-large bending machine is needed for processing and production, if this is the case, then the processing cost of the entire high-pole lamp will be very high, so the longer the lamp head of the high-pole lamp looks the easier it is to deform.


In the process of inserting the high-pole lamp, the specific operation method is to use a relatively thin mud rope to pull out some heavy objects on it and place them about 10 meters away from the entire high-pole lamp. Hold the top of the high-pole lamp with your hand, let their gravity sag naturally, and then use one eye to compare the vertical line of the high-pole lamp and the high-pole lamp with one eye at the position of 20 centimeters from the nylon rope, through this interweaving there are two ways, only in this way can it be straightened.
