通常所说的占20%～30%市场份额的中国国产挖掘机,其配套的核心液压元部件基本都是国外品牌产品。本土企业生产的少量核心液压元部件大都为国内“经济实用型挖掘机”配套。可以说,中国挖掘机核心液压元部件技术完全突破,并实现大规模生产配套的愿望,将率先在中国“经济实用型挖掘机”上实现。因 Commonly referred to as 20% to 30% market share of China-made excavators, supporting the core hydraulic components are basically foreign brand products. A small number of local enterprises producing a small amount of core hydraulic components for the domestic “economical and practical excavator ” supporting. It can be said that China’s excavator core hydraulic components technology breakthroughs and the desire to achieve large-scale production support, will take the lead in China “economical and practical excavator ” to achieve. because
