联邦德国的大型液压挖掘机技术无论是在西欧或是在世界上一直都处于领先地位。LIEBHERR、O&K和DEMAG是联邦德国三家著名的大型液压挖掘机制造公司。它们在主机设计上既有许多共同点又有不少独创之处。大体上可以这样说,如果把它们的大型液压挖掘机的各自特点综合起来,那么世界大型液压挖掘机先进技术的一个缩影就展现在我们面前。本文在着重介绍LIEBHERR公司的产品的同时,简要介绍其他两家公司产品的特点,最后讨论当代大型液压挖掘机的技术发展趋势。
The large hydraulic excavator technology of the Federal Republic of Germany has always been a leader in Western Europe and in the world. LIEBHERR, O&K and DEMAG are three famous large-scale hydraulic excavator manufacturing companies in the Federal Republic of Germany. They have many common points in the design of the host and many originalities. In general, it can be said that if we combine the characteristics of their large hydraulic excavators, then a microcosm of the advanced technology of the world’s large hydraulic excavators will be displayed before us. This article focuses on the products of LIEBHERR, and briefly introduces the features of the other two companies. Finally, it discusses the technological development trends of large-scale hydraulic excavators.
