杭州重型机械厂制造的WY-250液压挖掘机鉴定会最近在杭州重机厂举行。代表们听取了研制汇报,审查了技术文件,观测了样机现场作业,进行了技术评定,一致通过了鉴定。 WY-250液压挖掘机用于矿山开采、建筑、交通、水利、水电工程施工,具有优越的挖掘性能和机动性能,且通用化程度高,有取代机械式挖掘机的趋势。代表们认为,WY-250液压挖掘机是我国目前斗容量最大的液压挖掘机,该机总体参数合理、效率高、操作灵活、样机美观大方、质量较好。鉴定会上,大家希望配备多种性能的工作机构,改进驾驶室条件,进一步提高液压件寿命。
Hangzhou Heavy Machinery Factory WY-250 hydraulic excavator identification will be held recently in Hangzhou Heavy Machinery Factory. The deputies listened to the report of the development, reviewed the technical documents, observed the on-site operation of the prototype, conducted the technical assessment and unanimously passed the appraisal. WY-250 hydraulic excavator for mining, construction, transportation, water conservancy, hydropower construction, with excellent digging performance and mobility, and a high degree of generalization, there is a trend to replace mechanical excavators. The deputies believed that the WY-250 hydraulic excavator is the largest hydraulic excavator in our country at present. The overall parameters of the aircraft are reasonable, high efficiency, flexible operation, beautiful prototype and good quality. Appraisal meeting, we hope that with a variety of performance agencies, to improve the cab conditions, to further improve the life of hydraulic parts.
