In the national policy and investment direction of the impact, in the past year, the state continues to increase the investment in the central and western regions, loader and construction machinery as one of the most important models, which is bound to make it in the region has a broad prospect; From the needs of users, the state to encourage the development of a variety of common economic situations, private enterprises and individual users of the market demand is still rising, domestic large tonnage loader and other construction projects of large construction machinery demand is increasing, at present, the famous loader manufacturing enterprises are: Liugong, Liugong, Xugong Group, Longong, workers, Foton Rewo, Changlin CH Anglin. At present, the major domestic manufacturers continue to increase the investment in the loader technology research and development, constantly innovate and try a variety of different technical solutions, the loader connecting rod mechanism core components for technical improvement, efforts to achieve technical breakthrough, to meet a variety of different market demand, in order to become the loader industry leader as the goal. However, the domestic market competition is becoming increasingly fierce, and domestic manufacturers are facing serious challenges.
Foreign Status quo
Loader in the process of development mainly experienced three periods of development, since the 1970s and 1980s, the United States, Japan and other world manufacturing power enterprises in the loader reliability, safety, energy consumption and improve the efficiency of the work has made a lot of improvements. Especially the United States Caterpillar Company, its loader has been quite high reliability, under normal circumstances within 2-3 years basically will not fail. At present, the main development trend of loaders is high-tech and large-scale. In the design process, new technologies and new structures are adopted. For example, Caterpillar, Clark and other large wheel loaders adopt new technologies such as torque converter with variable capacity, whose bucket capacity reaches more than 16m3, and new technologies such as electronic monitor have emerged instead of ordinary instruments. From the 1990s to now, the United States Caterpillar, Japan Komatsu – direct leading the development of loader, widely used mechatronic integration and microelectronics technology, the operation gradually realized automation or semi-automation, pay attention to the appearance design and energy saving and environmental protection, in the operation to meet the driver’s comfort requirements, loader specifications gradually towards the large and miniaturized two-way, at the same time, Market multi – purpose and full hydraulic drive models also have a good prospect.

The trend of loader design
Domestic loaders are developing from low level, low quality and functional type to high level, high quality and economical and practical type. The main manufacturers continue to increase the technical investment, in the design efforts to achieve the key components and control system technology innovation, get rid of the current product design status, stand out from the domestic competition, become the leader of the loader industry.
(1) Different loading models, in the recent development process, the objective conditions and the total demand of domestic and foreign markets restrict the pace of its rapid development, large and medium-sized loader demand in the domestic market continues to accelerate.
(2) With the continuous development of different types of loaders by domestic manufacturers, the reliability of the whole machine has been greatly improved.
(3) Improve and optimize the structure of the loader system. Such as the system of vibration reduction, heat dissipation, dust, industrial modeling design.
(4) With the application of microelectronic technology and sensor technology in automatic gear shifting and hydraulic variable system, improve work efficiency, reduce the cost of the machine, more environmental protection.
(5) Improve safety and comfort. Keep the operator in the best position to work.
(6) With the increasing environmental problems, loaders also pay attention to the protection of the environment in the design process, reduce noise and strictly regulate emission standards.
(7) Constantly achieve technological breakthroughs to improve the service life and reliability of loaders.
(8) Later maintenance efforts to increase, reduce the number of maintenance.
