小型挖掘机有易操纵,小容量,多功能的运作等等,适当为这各种各样的土壤分散作用,能在狭窄的工作环境的操作范围。应用例如高速公路维护,环境美化,住宅建设、市政工程和农田建筑等。据此,本文对小型液压挖掘机工作装置与液压系统进行分析研究,以便更好地推广与应用。 Small excavators have easy to operate, small capacity, multi-functional operation, etc., suitable for a variety of soil dispersion, can work in a narrow operating environment. Applications such as highway maintenance, landscaping, housing construction, municipal engineering and farmland construction. Accordingly, this article analyzes and studies the working device and hydraulic system of small hydraulic excavator in order to promote and apply better.
