In 1879, American scientist Edison invented incandescent lamps to illuminate the world. However, over the years, incandescent lamps have ceased to be the mainstream of light bulbs for various reasons. In October 2012, China stopped selling 100 watts and above incandescent lamps. In January 2014, the US market also began to stop selling the best-selling 40-watt and 60-watt incandescent lamps. Starting from October 1 this year, China will also ban the import and sale of ordinary lighting incandescent lamps of 60 watts and above. Some experts predict that LED lights will become the biggest winner in the future. High-power incandescent lamps have gradually disappeared. Recently, when reporters visited the Beijing lighting market, they found that old incandescent lamps have disappeared everywhere, and replaced by various types of energy-saving lighting and LED lighting. At present, most of the lighting market is mainly based on the sale of lighting products. Even those who specialize in selling light bulbs are basically selling small-wattage household energy-saving light bulbs, or some decorative lamps such as laser lights, let alone High-power incandescent bulbs, even low-power incandescent lamps are a minority. There are too few people who buy incandescent bulbs now, and they rarely sell them when they enter the market. They are not willing to sell them over time. A merchant of Wanjia Lighting Lighting City said. Subsequently, the reporter went to the lighting and lighting areas of large supermarkets such as Wumei and Jingkelong, and found that the bulbs sold in the supermarkets were basically energy-saving bulbs and lamps. In the North Seven Building Materials City, 60-watt incandescent bulbs can still be seen everywhere, but there are very few 100-watts, and they are all unpackaged bulk goods. However, in some electrician shops in the urban-rural junction, incandescent bulbs of 100 watts and above are still available. Buying these high-power incandescent bulbs is all about engineering lighting needs, and the house that usually lives is basically no one to use this. The owner of the store told the reporter. Online incandescent lamp sales are still booming. The incandescent lamps on the market are gradually fading out of sight. Is there a high-power incandescent lamp sold on the omnipotent Taobao? With questions, the reporter conducted a search on Taobao. After inputting the keyword of the incandescent lamp 60W, 1412 items appeared, and the keyword search result of the incandescent lamp 100W also reached 200 pieces. In addition to some unnamed brands, these high-power incandescent bulbs are mainly based on brands such as Philips, Foshan Lighting, Shanghai Brand, and Shilin Lighting. The reporter opened a store specializing in the sale of Shanghai-brand incandescent lamps and found that in the description of the product parameters, the store wrote: Power 90W, or 100W, because the country needs to save energy and reduce consumption to produce 100W, so the bulb can only be marked as 90W, hereby declare. In the future, LED will gradually exit the market from incandescent lamps. Nowadays, the most used ones are energy-saving lamps. However, many people in the industry said that in the future lighting industry, LED will be popular. Nowadays, in some high-end and high-end lighting markets, LED household lamps have entered the eyes of consumers, and they are experiencing rapid development. LED kitchen lights, LED ceiling lights, LED crystal lights, LED spotlight LED products have unwittingly occupied half of the high-end lighting market. Xu Deheng, director of the Lighting Engineering Committee, said frankly that after development, the original LED household lamps have become more and more perfect. The brightness of a 7-watt LED bulb is equivalent to a 60-watt incandescent lamp, and it can save more than 85, the service life is up to 40,000 hours, the energy-saving lamp is only 8,000 hours, and the LED can also be quickly switched 50,000 times. . Song Xin, general manager of Bandung Huiyang, believes that when LEDs first appeared in the market, the prices were generally high and could not be accepted by the public. However, with the development of the past two years, more companies have invested in LED lamps. Prices are also becoming more approachable. Yang Jun, general manager of Red Star Macalline Lighting Expo, said that LED as a sunrise industry, the future has unlimited development possibilities, but only needs a time for the public to understand and accept. Su Hongmei, the general manager of the house, said that as consumers pay more attention to quality and brand, LEDs will be widely used like energy-saving lamps.
Derrick Crane
Derrick Crane is a type of crane used in construction and industrial settings. It is a type of Tower Crane that has a pivoting arm, called a jib, mounted on a vertical tower. The jib can be rotated to move materials horizontally, and the crane can also lift heavy loads vertically. Derrick cranes are often used in building construction to lift and move heavy materials, such as steel beams and concrete blocks, to different levels of a construction site. They are known for their stability and ability to handle heavy loads.
Derrick crane, also known as Roof Crane, is a specific style of lifting machine. It is usually a fixed building crane, meaning it is assembled and disassembled in the location where it is used. Generally, the crane is characterized by its long, fixed length tower. These cranes are typically used in locations where items need to be moved from a common initial point to single nearby location, like on shipping platforms and construction sites. BQ models of derrick cranes including 10T Derrick Crane 2533A, 6T Derrick Crane DCB20-6, 10T Derrick Crane DCB24-10, 12T Derrick Crane DCB30-12, 16T Derrick Crane DCB30-16, 18T Derrick Crane DCB42-18.
