随着水电工程的发展,工程建设对施工设备的要求不断提高,大型液压挖掘机(正铲斗容在4~6 m3范围)因其作业效率高、灵活动性能好等优点,就成为合理的选择。在举世瞩目的三峡和其它大型水电工程建设中,大型液压挖抛机在各种开挖施工中均起了关键的主力作用,保证了工程的顺利进行。 With the development of hydropower projects, the requirements for construction equipment for construction projects have been continuously raised. The large hydraulic excavators (with a capacity of 4 to 6 m3 at the bucket) are reasonably suitable for their high operating efficiency and good flexibility. select. In the world’s attention of the Three Gorges and other large-scale hydropower projects, large-scale hydraulic excavators and pavers all play a key role in various excavation and construction to ensure the smooth progress of the project.
