Why is the lamp head of the high mast light poles tilted?

Through scientific and reasonable design and installation, regular inspection, and maintenance, we can minimize the negative impact of lamp head tilt and create a safe and bright living environment for citizens.

High mast light poles are practical for large squares and open roads and are also common street lamps. With their lifting conditions, the pole body can be designed to be about 40 meters high. At this height, the light source at the top of the pole can illuminate a large enough area. This is also the most significant advantage of adapting to square lighting.

Although high mast light poles are very good lighting fixtures, their lifting system has a certain technical content. If the design is unreasonable or the operation is improper, it will be quite dangerous. If friends who often drive pay attention, they can observe that many high mast light poles on both sides of the road have a common feature, that is, the lamp plate at the top of the lamp pole is tilted. What is the reason for this? The following will teach you to understand the cause and solution of the problem.

The weight of the high mast light poles plate will vary according to the height of the lamp pole and the number of light sources, but the lightest one also weighs several hundred kilograms. If such a heavy object of several hundred kilograms falls from a height of tens of meters, the result can be imagined. (I have shared the lifting principle of high mast light poles with you in other articles so I won’t go into details here). The lamp panel of the high mast light poles is pulled up by a wire rope through a winch. When the lamp panel is raised to the appropriate position, it will be hung by the three hooks at the top of the high mast light poles. At this time, the wire rope can be relaxed without force, but the three hooks at the top of the pole body bear all the weight.

The common problem of the tilt of the lamp panel of the high mast light poles is directly related to the three hooks. The three hooks for hanging the lamp panel are evenly divided, that is, only when all three hooks hang on the lamp panel, the lamp panel will be flat. As long as one of the three hooks is not hung, the lamp panel will tilt 100%. In principle, the lamp panel of the high mast light poles has two safety protections, namely hook protection and wire rope protection. It stands to reason that even if all three hooks are not hung, the lamp panel will not fall down. However, for a responsible construction team or manufacturer, it is obviously an irresponsible work attitude to regard the absence of problems as an excuse for not doing the best work. We should understand that it is always safer to hang all three hooks than to hang two or one.

There are two reasons why all the hooks cannot be hung. First, the hook size design is unreasonable. Second, the lamp panel is uneven when it is raised because the three steel wires are unevenly stressed. These two problems are the direct reasons why all the hooks cannot be hung up, but they are easy to solve. It depends on whether the construction party is willing to solve them.

If you don't want to be fooled by the construction team, there is a very simple identification method. That is when the lamp panel is raised to the right position, the installer tells you that it is ok. At this time, don't listen to him. Go over and push and pull the main steel wire driven by the winch. If you can't push it, it means that the steel wire is under stress and the hook is not working. This is very dangerous. At this time, tell the installer to loosen the steel wire so that the hook is stressed. If the lamp panel starts to drop or tilt after the steel wire is loosened, it means that the installation is not qualified. Don't give them money and ask for immediate repair until the steel wire is not stressed after the lamp panel is raised and the lamp panel is parallel. It is qualified, which is safe and beautiful.
