Construction machinery The general term for construction machinery used in engineering construction. It is widely used in construction, water conservancy, electric power, roads, mines, ports and national defense and other engineering fields, with a wide range of types. And second-hand construction machinery is also called old Engineering Machinery (old engineering machinery), or used construction machinery, but still usable construction machinery.

Such as levelling machines, ballast cleaning machines, etc. ⑧ Rock drilling machinery. Such as rock drilling rigs, pneumatic rock drills, etc. Electric rock drills, internal combustion rock drills and down-the-hole rock drills, etc. ⑨ Other construction machinery, such as bridge erecting machines, pneumatic tools (pneumatic tools), etc.
Guangya Exhibition Revelation: The traditional lighting industry has taken a new path
Recently, the 19th Guangzhou Guangya Exhibition was in full swing and the scene was unprecedented. According to the reporter's survey, more than 95% of the exhibitors in this exhibition are LED industry practitioners, which is closely related to the rapid development of the LED industry. However, in this big wave of LEDs, there are also some cool observers and industry innovators. Shenzhen Yuxuan Technology Co., Ltd., located in Zone C of Hall 7, has aroused the strong interest of journalists. “We are the world's first value-added service provider for light sources,†said Mr. Shan Cun, Marketing Director of Haoxuan Technology. “What does it mean to add value to the light source? Why do you want to do value-added services?â€. In the face of the reporter's doubts, the mountain always came. He believes that the value added of light source refers to shielding the original shortcomings based on the original light source, exerting more advantages and creating more value. Future lighting will not be the LED to completely replace the traditional lighting, but each to play their own advantages, each with its own market, and the same. Any new light source will take a long time to adapt. It is impossible for LED to completely replace traditional lighting. The traditional lighting market is stable and has a large amount of storage. People's habits are difficult to change easily. Therefore, Hyun Hyun Technology has put forward a new concept of deep energy saving, deep environmental protection and healthy lighting. It upgrades and matures the mature fluorescent lamp products, and innovates and develops insulated energy-saving lamp casings, aiming to provide people with a lower carbon and comfortable. Safe and healthy lighting life. Yan Hsiao believes that the concept of energy saving and low carbon should be based on the entire life cycle of products, covering production links, use links, maintenance and replacement links, recycling and recycling, and comprehensively consider all aspects to achieve “deep energy conservationâ€. The new products of Haoxuan Technology can increase the illumination of existing lamps (50%-120%), reduce procurement costs and significantly reduce the cost of use. During the speech, he held the metering instrument for the reporter on the spot. When the product was not used, the illumination at the distance of 1.5 meters was 105, and after using the product, the illumination was 186, which really improved a lot. . Under the same illumination demand, the efficiency of use is greatly increased, and the number of uses is greatly reduced, which means energy conservation, in other words, the increase in energy. The understanding of environmental protection should be comprehensively and fully considered from every link, such as product design, material selection, production, use, and recycling. It is not comprehensive to evaluate the pollution of a certain product. Mr. Shan said that the use of ç¿Œ äº§å“ products can minimize the risk of environmental pollution at every stage, especially the risk of mercury leakage, which is extremely important for environmental protection. On the other hand, it is to increase the health of people. In recent years, as people's awareness of environmental health has become higher and higher, the light pollution and health damage caused by products in the use of links have not been neglected. With the use of ç¿Œ äº§å“ products, it can 100% UV, isolate blue light, prevent glare, reduce nighttime flying insects, and reduce the health risks of light sources in many ways. In the original fluorescent tube and 翌炫 products UV test, the test instrument data shows 430 and 0, ç¿Œ Hyun products do not have any UV. At the Guangya Exhibition, which is dominated by LEDs, this product model and product concept are unique, which has aroused great interest from exhibitors at home and abroad. It is understood that this product has been applied to home lighting, factory lighting, kindergartens, shopping malls, office buildings, etc., and the market response is very good. “The debut of Guangya Exhibition is the beginning of the concept of “Hyun Hyunâ€, and we believe that our lighting concept will be recognized by more people, because this is the future trend. As the world’s first light source value-added service provider, the new field The pioneer, we have enough confidence to do this business." Shan said with great ambition. [img]http://[/img]
