In the highend users with the needs of small change, directly contributing to small enterprises with the differentiation, with the concept of progress and consumer financial strength of the expansion, some of the rural users (particularly in the industrialized operation of agriculture users) product performance and aftersales service and put forward higher requirements. Liaoning Anshan Haihong such as production of highend products not only with small to have their own patented technology (use of mechanical devices greatly enhance the performance of its products, avoid using electric control, hydraulic devices, such as product performance after upgrading to the use of rural users increased maintenance costs ), and introduced the noncontroversial services. Especially in big enterprises with increased involvement of small enterprises with pressure, the end of 2021, the Dragon Holdings acquired Henan Baiyun electrical and mechanical equipment involved in the production of small fields. Small with a huge potential market demand, but only to meet user needs, and guide the user needs, small equipment will have lasting vitality. Existing small enterprises with wellknown loaders already facing small enterprises involved with the production sectors and small users to buy equipment or equipment, such as small excavators alternative products twin crises, with the production of small enterprises can take the initiative to upgrade their win more more time and greater market space. Any industries are indispensable for the development of market petition and government regulations two factors. With the status quo on small industries, market petition and excessive government regulation missing, the entire industry in a very low level of operation development, and a lack of development of the industry often staying power will gradually shrink, or even disappear. First to be addressed is the issue of trade with small, small equipment products really have their own products definition, a special product standards. Although at this stage with small user groups mainly concentrated in the rural market, but the market coverage of the future is certainly both urban and rural areas, this is because small equipment can be widely used for municipal maintenance, landscape construction, building and construction, underground loading and unloading areas. Second, improve industry access threshold is a feasible solution. Small equipment industry can learn from the industry39。s most advanced technology wheel loader on the basis of the successful development of the power of 162 KW of shovelfit wheel loaders, stereotypes for Z450 (later ZL50), and in 1971 December 18, formally appraised by experts. Thus the birth of China39。裝載機(jī)發(fā)展概況 A loader is a type of construction equipment (engineering vehicle) machinery that is primarily used to load material into another type of machinery (dump truck, conveyor belt, railcar, etc.).Loaders are used mainly for uploading materials into trucks, laying pipe, clearing rubble, and digging. A loader is not the most efficient machine for digging as it cannot dig very deep below the level of its wheels, like a backhoe can. Their deep bucket can usually store about 36 cubic meters of earth. The front loader39。s first articulated wheel loader, thus creating our industry loader formation and development history. Z450type loader with hydraulic mechanical transmission, power shift, Shuangqiaoshan drive, hydraulic manipulation, articulated power steering, gas oil Afterburner brake wheel loaders, and other modern, the basic structure of the world39。s largest equipment manufacturers licensing system, in terms of production quality suitable restrictions and improve the industry39。s a major turning point. The standard was worked out by the industry after the division of labor, LIUGONG Xiamen ZL40 the manufacture of the large and medium wheel loaders, as workers, to the following small and mediumsized manufacturing ZL30 wheel loaders, and gradually formed a LIUGONG Xiamen workers, and 10% for workers at the loader to four backbone enterprises. To the late 1970s, early 1980s loader manufacturing enterprises in China has increased to more than 20, China has initially formed the loader industry. So far, China has developed wheel loader to the third generation, but the basic structure is still the Z450 (ZL50) evolved from. Change is not a very large second generation, third generation of some larger changes. 2021 China loader industrywide total sales have exceeded 30,000 Taiwan, the world loader in the forefront of the market. Therefore, at present, China has bee the world39。s modern 20 wheel loaders began in the mid1960s of the Z435. The aircraft as a whole rack, rear axle steering. After years of hard work, the attraction was the world39。s bucket capacity is much bigger than a bucket capacity of a backhoe loader. Loaders are not classified as earthmoving machinery, as their primary purpose is other than earthmoving. Unlike most bulldozers, most loaders are wheeled and not tracked, although track loaders are mon. They are successful where sharp edged materials in construction debris would damage 2 rubber wheels, or where the ground is soft and muddy. Wheels provide better mobility and speed and do not damage paved roads as much as tracks, but provide less traction. Unlike standard tractors fitted with a front bucket, many large loaders do not use automotive steering mechanisms. Instead, they steer by a hydraulically actuated pivot point set exactly between the front and rear axles. This is referred to as articulated steering and allows the front axle to be solid, allowing it to carry greater weight. Articulated steering provides better maneuverability for a given wheelbase.
