China's excavatorproduction started late,from the 1954 Fushunexcavator factoryproduced the firstbucketcapacity ofmechanical1m3 singlebucket excavatorso far,largely through themappingof imitation,independent research and developmentandimprove the developmentof three stages.
The early founding of newChinese,dominated bygeneric mappingthe former Soviet Unionin twentieth Century 30 ~40 in theW501,W502,W1001,W1002 and othertypeof single bucket excavator,startedChina's excavatorproduction history.Because of the needof national economic constructionat the time,has establishedmore than tenexcavator factory.Since 1967,China has independently developedthe hydraulicexcavator.The earlydevelopment ofsuccessful productsmainly Shanghaiconstruction machinery factoryWYl00,Guiyangmining machinery factoryW4-60,Hefeimining machinery factoryWY60 typeexcavator.Later theWYl60Changjiang excavatorfactoryand Hangzhou heavymachinery plantof WY250 typeexcavator.They arefor the formation anddevelopment of our country's industryof hydraulic excavatorhas taken a veryimportant step.
In twentieth Century80at the end of the 1960s,theexcavator productionplant in Chinamore than 30,more than 40productionmodels.Insmall hydraulicexcavator,has formed a series,bucket capacity of0.1~ 2.5m3 in 12grade,20 kinds of models,but also the production of 0.5-4.Om3and10m3,12m3mechanical transmissionof large miningexcavator,excavator1m3tunnel,4m3 long armof excavator,1000m3/ hdumpingmachine,alsodeveloped thebucket capacityO.25m3marine hydraulicexcavator,bucketcapacity of O.4m3,O.6m3,0.8m3amphibiousexcavator.But in general,the excavatorproduction in Chinaand small batch,dispersion,production technology andproduct qualitycompared with the internationaladvanced level,there is a big gap.
