摘　　要：液压挖掘机诞生于约60年前,此后在种类繁多的工程机械中迅速发展成为最具市场成长性,需求量约占全球工程机械需求量近半的机种。液压挖掘机的成长伴随着城镇化的进程,在发达国家人口密集的城市,由于多种多样的建设需要,具备通用性的液压挖掘机被广泛应用于工程施工中。Hydraulic excavator was born about 60 years ago. After that it became a rapidly developing equipment type in a wide range of construction machinery, of which demand accounted for about half of the global demand for construction machinery. Hydraulic excavators grows with the process of urbanization. In the densely populated cities in developed countries, due to a variety of building needs, universal hydraulic excavators are widely used in engineering construction.
