1 概述机械电子部天津工程机械研究所与贵阳矿山机器厂联合研制的WLY100型轮胎式液压挖掘机,已于1988年4月通过部级鉴定。该机系目前国产最大等级的轮胎式液压挖掘机,技术性能接近联邦德国同类产品的水平,已按规定完成了1000h作业和1500km行驶的试验。在贵州省南、北盘江及红水河整治工程中,使用该机(配1.0m~3抓斗)抓取河道积石,作业300个台班以上,工作情况良好,使用可靠,具有挖掘力大、生产率高和机动灵活等优点。WLY100型液压挖掘机除可配装反铲外,
1 Overview The WLY100-type hydraulic excavator jointly developed by Tianjin Institute of Construction Machinery and Guiyang Mining Machinery Plant of the Ministry of Mechanical and Electronic Technology has passed the ministerial appraisal in April 1988. This machine is currently the largest grade of hydraulic excavator made in China. Its technical performance is close to the level of similar products in the Federal Republic of Germany. It has completed 1000 h operation and 1500 km driving test according to regulations. In the South, Beipanjiang and Hongshui River remediation projects in Guizhou Province, this machine (with 1.0m~3 grapples) was used to grab the river stones and operated over 300 shifts. The working conditions were good, reliable, and excavated. Strong, high productivity and flexibility. In addition to WLY100 hydraulic excavator can be equipped with back shovel,
