Some time ago, I deeply Xiagong Chu Sheng workshop, learned aerial work as a special vehicle to work tools and materials by lifting platforms, the installation of various aspects of control when reached a certain height and maintenance Such work, through careful and accurate analysis of the market, this type of high-altitude operation special vehicle will be more and more applied to the construction process of large and medium-sized cities with the further development of the city.
JIS" Stands for Japanese Industrial Standard and are published by the Japanese Standards Association (JSA) which is the equivalent of ANSI in the United States. They are created and updated by the Committee of the Japanese Industrial Standards (JISC). Like JSA to ANSI, the JISC is similar to the American Society of Mechanical Engineers (ASME).
Japan Industrial Standard is yet another option for metric sizes. Provided in JIS5K, JIS10K, JIS15K, and JISK20K pressure classes, we can offer Slip On, Blind, and Weld Neck varieties in Raised Face or Flat Face configurations. These are typically made of 316/L or A105, but as usual, all alloys are available!
Much like DIN / metric flanges, the JIS Flange specification offers a slightly wider variety of slip weld configurations for the purposes of space limitations and suitability for existing pipeline equipment. For instance, a customer can request a slip on with or without a hub as standard, or even a ring type flange, and all of this within the same B2220 specification.
JIS flanges are commonly found in exported pressure equipment and pipe assemblies from Japan. Many large ships and sea vessels which travel through international waters and service the Pacific rim will utilize equipment made to this standard, as parts and servicing for this specification are widely available.

It is understood that at present our national high-altitude operation special vehicles are generally concentrated in cities or towns. Due to the wide use of special vehicles for high-altitude operations and the numerous industries touched upon, the content of operations in each industry is not the same, according to statistics. The data show that 5,000 people were killed in the accidents that caused the death of workers due to the failure of the work baskets in the process of city building maintenance in China. It is understood that such high-altitude operations have been made fun in some developed countries. However, instead of using special vehicles for high-altitude operations, the use of high-altitude special vehicles in urban construction in the future will be a normal phenomenon. According to the survey, the equipment leasing industry in developed countries is currently the main force in the procurement of special vehicles for aerial work, which accounts for 80 percent of the total demand. However, the data investigation in this area in China is zero, because the users want to use it. It is necessary to purchase talents, and along with the constant development of the engineering equipment leasing industry in China, users can rent them without funding, which will inevitably lead to an increase in some leasing industries. It appears that the leasing industry will be the market for high-altitude jobs in China. An industry with the greatest potential.
Through the above investigation , it is still very small to compare the actual demand of the current high-altitude operation special vehicle with the actual demand potential, that is to say, in the next decade or even several decades, the high-altitude operation special vehicle industry There will be a sustained and rapid development momentum. It is estimated that by 2015, the number of high-altitude special-purpose vehicles in China will increase to about 40,000 units, and its average annual growth rate will reach 10%.
