抚顺挖掘机制造厂最近研制成功两种小型液压挖掘机。1984年12月在辽宁省抚顺市召开了省级技术鉴定会议。国内有关厂、所、校和使用单位派员组成技术鉴定委员会,审查了技术文件,抽检了该两产品的部分性能参数,证明设计依据充分、整机布置合理,结构紧凑、用途广泛。WY40ZR型专用于沼泽地和软地面施工,它填补了我国这类挖掘机械的一项空白。
Fushun excavator manufacturing plant has recently developed two types of small hydraulic excavators. In December 1984, a provincial technical appraisal meeting was held in Fushun City, Liaoning Province. The domestic factories, schools, schools and the use units sent personnel to form a technical appraisal committee, reviewed the technical documents, spot-checked some of the performance parameters of the two products, proved that the design basis was sufficient, the overall layout was reasonable, the structure was compact and the application was extensive. The WY40ZR type is dedicated to the construction of wetlands and soft grounds, and it fills a gap in this type of excavation machinery in China.
