摘要
中国工程机械工业协会名誉会长，首席顾问韩学松在2011年中国工程机械主要设备保有量浅析一文中，按照他的公式通过计算和估算截止2011年末我国液压挖掘机的保有量为121．2-131．2万台。
According to estimate,hydraulic excavators of China has been reserved 1.212~1.312 million units by the end of 2011.In industrial developing countries,life span of a hydraulic excavator is usually 5~6 years or 6~7 years,and it is on average far less than that at our country.Therefore this time we initiate that hydraulic excavators with life span having exceeded 10 years shall be compulsory updated.After obtaining some experiences,the system that hydraulic excavators with life span having exceeded 8 years shall be carried out compulsory updated as well.
