工程机械的装配，过去一直采用分散定台位的装配方法。这种方式的装配质量随机性大，劳动强度高。随着生产的发展和生产批量的增加，大部分生产厂家都安装了装配线。但由于工程机械整机一般具有质量大、尺寸大的特点，一些结构类型的装配线并不适合于工程机械的装配，致使一些
Construction machinery assembly, the past has been used to set the assembly method of decentralization. This method of assembly quality randomness, labor-intensive. With the development of production and production volume increases, most manufacturers have installed assembly lines. However, due to the general construction machinery quality, large size, some of the structural types of assembly line is not suitable for assembly of construction machinery, resulting in some
