一、概述随着我国公路工程建设事业的发展,筑路机械的品种门类日益繁多,由此在筑路机械行业中,出现了以敷设钢制轨道为其行驶支承面的机械。比如可供在铺设水泥混凝土道路中使用的西德“福格勒”(VOGELE)公司的jun-ior和senior型轧道式列车机组,美国“格玛柯”(GOMACO)公司的C-450型混凝土整面积,以及大型水泥混凝土工程中场拌所 I. Overview With the development of China’s highway engineering construction industry, there are a growing number of types of road construction machinery. As a result, in the road construction machinery industry, machinery for laying steel rails as supporting surfaces has emerged. For example, the VOGELE company’s junior and senior rail trains can be used in the laying of concrete roads. The Gomaco company’s C-450 model Concrete whole area, and large-scale cement concrete works
