杭州重型机械厂最近研制成功2.5米。的WY250型履带行走、全回转液压单斗挖掘机。可用于金属和非金属矿山的露天开采、铁路与港口建设以及大型水利工程施工。能够挖掘经过爆破的Ⅴ—Ⅵ级土方或石方。1982年7月上旬,机械工业部委托浙江省机械工业厅在杭州市召开了技术鉴定会议。会议期间,观看了样机表演、按鉴定试验大纲进行了性能测试、审查了技术文件与图纸。证明该机研制是成功的。可以投入批量生产。
Hangzhou Heavy Machinery Factory has recently successfully developed 2.5 meters. WY250 caterpillar walking, all-rotary hydraulic bucket excavator. It can be used for open-pit mining of metal and non-metal mines, construction of railways and ports, and construction of large-scale hydraulic projects. Can excavate blasted V-VI earth or stone. In early July 1982, the Ministry of Machinery Industry commissioned the Zhejiang Provincial Machinery Industry Department to hold a technical appraisal meeting in Hangzhou. During the conference, they watched the prototype performances, conducted performance tests according to the qualification test program, and reviewed technical documents and drawings. It proves that the development of this machine was successful. Can be put into mass production.
