Other configurations unchanged, a high-pole lamp with a lifting system, a non-lifting system, the price difference reaches 8000 yuan, the gap is very large. Although the cost of a lifting system will not be higher than 4000 yuan, but the design structure of the lamp pole position after the lifting system is much more complex than that of the ordinary lamp pole, which is also the reason for the high price. Because the high-pole lamp belongs to one-time investment and the price is expensive, so the damage of the high-pole lamp to a certain extent (not to the extent that it can not be repaired) will not be easily replaced, or need to be solved through maintenance. There are many relations between the level of maintenance cost and the damage degree of your system, and whether the lifting system is brought or not. It is clear to make the project clear if the maintenance does not bring the lifting system. High pole lamp for descending system. The lifting crane needs to be invoked at a fixed cost of thousands of yuan, so in the long run, the maintenance cost alone is a large expenditure, so if the funds are not very tense, it is recommended to take the lifting, not only the later maintenance is convenient to reduce expenditure, but also there is no danger of any high-altitude operation.
