美国卡特彼勒公司80年代利用现代化设计开发了E系列装载机,90年代又出台了F系列,日本小松公司70年代末引进美国技术,80年代推出WA系列。当前结构设计的主要动向是: (1)采用模块化设计 用少数模块组成多种不同功能和性能的产品。这样就大大提高了零部件通用化水平。
The United States in the 1980s developed the E-series loader with modern design and introduced the F series in the 1990s. The Japanese company Komatsu introduced American technology in the late 1970s and the WA series in the 1980s. The current structural design of the main trends are: (1) the use of modular design with a few modules composed of a variety of different functions and performance of the product. This greatly improves the level of common parts.
