At present our country store house bar type car mainly bulk grain bulk truck, bulk carriers, livestock transporters, feed poultry truck, a beekeeper car etc. Among them, the bulk grain bulk truck, bulk feed transporter designed for warehouse cage type car, livestock transporters, poultry truck, a beekeeper vehicles for the fence type car. With the development of society, the automobile transport have developed rapidly. Among them, bulk transportation and container transport is the main development direction of automobile transport. Euramerican developed country since the 1930s began to research and application of bulk transportation, at present the scattered grain of material transportation accounts for about 80%, bulk truck technology also have very big development. Our bulk transportation start later, in the late 1960s first car market, then car bulk cement of various types of arise bulk cement truck, food truck, bulk cement truck, bulk pulverized coal electric vehicle, etc. At present, our country bulk transportation level is still very low, although since 1970s some domestic research departments and manufacturers in the bulk carriers, especially the development of car bulk cement achieved gratifying achievements, but compared with the developed countries, the country is still a big gap. In today's world, with the rapid development of economy, the expressway mileage rapid increase, car to specialization, fast pace, the development trend of ChongXingHua direction is more and more apparent, contributed to the special demand increases year by year. A. has become transportation and various special use main in the automobile industry that will be a pivotal status. Special automobile refers to device has a special equipment, have special function, used to undertake special transportation tasks or special assignments car, special automobile manufacture, production and application of not only in achieving specialization transportation and operations by the social attention and welcome, and in improving transportation efficiency and reduce the transportation cost, expand the application fields car has played a very important role. At present, China's pig, ox, sheep livestock and chicken, duck, goose to wait the buying and selling of poultry, egg transport is used mostly ordinary cars. Purchase season, still use tractor transporting, thus inevitable existence many insurmountable shortcomings. If transport unsafe, livestock high mortality rate, transport losses, etc. Each country by hundreds of millions of dollars of losses. Due to the economic benefit of transport backward, and low, make livestock management appear generally losses. Then double livestock transporters emerged, double livestock truck belongs to the store house bar type truck. And the standard of store house bar called store house bar type truck in special truck, car on exterior design, strive to modelling beautiful, internal rational structure, advanced technology and using high quality steel skeletons in strict accordance with industry standards, welded by jig, compartments board into corrugated type, suppress and high strength, with light-weight, store house bar railing can half complete disconnect and optional splits, lifting, convenient and practical, safe and reliable, etc. According to user requirements design double fresh animal vechile, lots of fruits and vegetables truck, etc. Suitable for the masses of users ZhongDuanTu highway transportation use, also can make ordinary bills in highly developed car use, the highway transportation, particularly the rapid development of modern logistics industry. Store house bar type truck will get rapid promotion, popularity. Is the city, the development of logistics market intercity economical products. Although China special vehicle development has made great progress, but China special automobile industry with overall from Europe, America, Japan and other countries and regions, compared to the advanced level in domestic special automobile market development is slower, market segmentation, product ray enough big, cannot satisfy user homosexual individualized demand, low level of competition is relatively serious, mainly reflects in following aspects. (1) production enterprise too much too scattered, currently China most special automobile production enterprise symptom is: ChangDian dispersed, on a smaller scale, development ability are relatively weak. (2) product structure is unreasonable, because China is in developing countries to developed countries in the process of transformation, infrastructure construction also at peak, so China special automobile market demand or to transport supplies, meet the infrastructure construction is given priority to, plus China labor resources abundant, the market form decided the Chinese special vehicle structure form a single, presented at single function, low value-added products too many conditions. (3) high scientific and technological content of products lack of independent research and development capacity. (4) production process tooling level is low. (5) the development and production of special chassis with market demand still have difference. (6) special-purpose automobile market development certain limits. The development of specialized automobile industry in China market space is huge, economic development brings refinement, social division of labor of special automobile demand performance for diversity. Along with market demand increases, technology demand increase, will push towards the brand, specialized automobile factory specialization, collectivization, scale direction. The new situation, how to narrow the gap with foreign developed countries, the Chinese special automobile market bigger and stronger is an important and far-reaching subject. With China's sustained economic development, national policies and the gradual improvement in the industry, believe that the joint efforts, our special automobile industry through actively participates in the international market competition, will catch up with and even surpass the developed countries of the world development level, achieved by China manufacturing to China to create leap. Along with the healthy development of the national economy, the continued expansion of domestic demand, our special automobile market will obtain rapid development. In the next few years are mainly concentrated in focusing on the development of urban construction, service and high grade highway transportation aspects. Specific to the following aspects: 1, Dump Truck With the expansion of domestic demand in recent years the policy of national implementation, actively investing in infrastructure construction and the construction of large project, all of the corresponding dump vehicle demand have plenty of growth, and the big and heavy tonnage is the direction of development, mov proportion will further increase. 2,Traction car With China's highways and roads of growth, the highway, the highway expansion to improve transport efficiency brings the need, this will be for the leading models in the future in highway's big volume of van semi-trailer will greatly increase, the corresponding half hanged tractor demand will also be greatly increased, and long distance transportation of high-power, highway of tractor is the hot market demand. 3, Tank car Tank cars including common tanker, bulk cement car, concrete mixing truck, and use the high pressure tanker relatively few, chemical liquid gas tanker, suck unclean liquid tanker, etc. Along with the development of the western region oil and gas resources will drive petrochemical oil-refining development, so big a tanker demand will also increase. The half hanging large-tonnage tanker growth rate will also accelerated. 4, Bulk cement car and Concrete mixer In recent years, along with the rise of the housing boom and public infrastructure construction of development of bulk cement caused the car and concrete mixing the car is in great demand. 5, Municipal transport Municipal transport including large buses, pavement sweeper, can change the CheXiangShi car, suck FenChe garbage compression, sewer dredge car, all kinds of YouZhengChe, sprinkler and cleaning tall buildings to aloft working car etc. As countries establish accelerating urbanization, in order to adapt to all kinds of urban construction need special construction projects will be huge demand is very rich, and varieties will. Urbanization will not only drive economic development, at the same time for all sorts of special needs will increase up, pull the car industry development. 6, Highway maintenance vehicles The rapid development of national highway, with "five longitudinal and transverse" give priority to seven of road network, the complete skeleton national highway traffic total mileage will reach 3.5 million kilometers. As the great western development constantly advancing and western regions of the increasing expressway mileage, large highway pavement maintenance QingZhangChe, car, pavement sweeper, rescue trailers, take the large crane JiuYuanChe etc have big market. 7, Fire trucks The number of specialization, the special jin-wei more and more, but the actual situation of car from view, at present our country engines in quantity and quality of there is great, especially models lack structure unreasonable, the special low proportion of the total amount of 69.2%, water pottruck accounted for, and the special (except pitchers, dry powder, foam outside of the vehicle) only 10%. In the future the special will become the specialization of the key demand. 8,Medical exclusive A. including the ambulance, medical treatment of medical CaiXieChe, epidemic prevention ambulance, car, assay car etc. 2003 national due to the influence of the SARS epidemic and southeast Asia countries currently popular bird flu virus, will greatly boost domestic medical exclusive demand. 9, Airport exclusive Current, the country to establish the airport construction on the development of western China, along with the airport is built, the airport car, need the ramp baggage car, food supplies, the plane large car tanker truck, JiuYuanChe, fire truck aircraft tractor, etc. In addition to the airport's power engines for no other than domestic production of all with enterprise production, but one of the big tonnage refuel aircraft in the car, structure and technical performance, can not completely guaranteed, arid improve soon pass level. 10, Oilfield exclusive Oilfield in universal special is the heavy tonnage truck chassis with various drilling and workover on such a special equipment operation. Along with the development of the western oil resources, the western regions with the vehicle demand desert oilfield large cementing car, drilling car, life cars, car and other types of repairing. 11, Container car With the high-speed development of national economy, modern logistics speeding up and used in meat, quick-frozen food, cold, dairy products and fruit class commodity production and transportation, container transportation will increase of China's automobile transportation development is an important direction of container car every year, the demand will increase greatly. Along with the development of our national economy, improvement of people's living standard. People on the poultry, meat products demand has increased dramatically. And livestock and poultry breeding sites away from downtown, so it needs to fresh livestock and poultry transportation to the designated place. So the market demand of livestock transporters bigger also.
