Excavators yog Ameslikas ua manually; lub sij hawm spanning ntawm lawv invention rau 2013 tshaj 130 xyoo. Nyob rau lub sijhawm no, lawv tau hloov zuj zus los ntawm chav -powered, slewing- hom excavators rau cov uas tau tsav los ntawm lub tshuab hluav taws xob lossis lub tshuab hluav taws xob sab hauv, nws thiaj li ua rau tag nrho tsis siv neeg hydraulic excavators uas koom ua ke txhua yam, hluav taws xob, thiab hydraulic technologies. Thawj hydraulic excavator tau ntse tsim los ntawm Fabkis lub tuam txhab Poclain.
Daim ntawv thov ntawm hydraulic technology coj mus rau qhov tshwm sim ntawm tsheb laij teb -mounted hydraulic backhoe excavators nyob rau hauv 1940s. Nyob rau hauv 1951, Poclain launched thawj tag nrho hydraulic backhoe excavator, qhib rau tshiab possibilities rau excavator technology; Tom qab ntawd, thaum ntxov mus rau nruab nrab -1950s, tag nrho hydraulic excavators nrog tag nrho - viav vias muaj peev xwm- muaj nyob rau hauv ob qho tib si towed thiab crawler-mounted versions-tau tsim.
Thaum ntxov qauv hydraulic excavators cia siab rau hydraulic technologies yoog los ntawm aircraft thiab tshuab cuab yeej; lawv tsis muaj hydraulic Cheebtsam tshwj xeeb uas haum rau ntau yam kev khiav hauj lwm ntawm excavators, raug kev txom nyem los ntawm inconsistent manufacturing zoo, thiab tsis muaj ib tug tag nrho cov kev pab cuam. Txij xyoo 1960 mus, hydraulic excavators tau nkag mus rau theem ntawm kev siv dav dav thiab kev loj hlob sai, uas muaj kev loj hlob ntawm cov tuam ntxhab thiab cov qauv, nrog rau kev nce siab hauv cov ntim ntau lawm. Los ntawm lub sij hawm ntawm 1968-1970, hydraulic excavators accounted rau 83% ntawm tag nrho cov excavator ntau lawm, sai li sai tau mus rau 100% cim.
