建筑工程造价（Construction cost） Abstract: since 90s, foreign engineering machinery has entered a new period of development. With the widespread application of new technologies, new structures and new products are emerging. After the completion of the task to improve the reliability, the focus of technology development is to increase the content of electronic information technology products, and strive to improve product standardization, serialization and general staff, improve the driving conditions, to the development direction of energy saving and environmental protection. As the construction machinery involves many types of machines, this paper focuses on the wheel loader (hereinafter referred to as loader) as an example, and gives a brief introduction of its technical status, new technology and new structure, as well as the development trend. New technology and new structure In recent years, engineering machinery products to foreign information technology as the guide, in the engine fuel combustion and electric control, hydraulic control system, automatic control, visual driving, accurate positioning and operation, fault diagnosis and monitoring, energy saving and environmental protection, made a lot of research and development of many new structures and new (or system) improve the high-tech products, engineering machinery, and promote the development of Engineering machinery. Modular mining systems, the companys bulldozer positioning system, helps drivers accomplish tasks such as slope and soil handling. Has the image of the console mounted cab display machine in operation in the region to the position of the driver, and display the key operation parameters, such as blade angle or by moving the earthwork volume. T r im B Le products are Site, V, isio, N, G, PS, can achieve accurate control of the slope, driving room visual display system to guide the driver accurate work, accuracy up to cm level. New technology and new structure of 3. loader In order to improve the o
