Los ntawm thaum ntxov xyoo pua 20th mus rau lig 1940s, excavators nkag mus rau ib theem ntawm ntau haiv neeg nyob rau hauv lub hwj chim thiab locomotive systems. Xyoo 1910, thawj lub tshuab hluav taws xob-tsav ib zaug- thoob excavator tshwm sim; nyob rau hauv 1912, roj av thiab roj av cav-tsav tag nrho- tig ib leeg- thoob excavators tshwm sim; Xyoo 1916, lub tshuab hluav taws xob diesel-tsav ib leeg- thoob excavators raug tsim; Xyoo 1924, lub tshuab hluav taws xob ncaj qha tau pib siv rau hauv ib qho - thoob excavators; taug qab locomotives thawj zaug tau txais kev pom zoo nyob rau hauv 1910. Nrog rau txoj kev loj hlob ntawm kev lag luam tsheb, log locomotives tau dav siv nyob rau hauv me me excavators. Nyob rau xyoo 1930, taug kev locomotives tshwm; nyob rau hauv nruab nrab - xyoo 1950, Lub teb chaws Yelemees thiab Fabkis tau ua tiav cov kev sib hloov hydraulic excavators, kos ib theem tshiab hauv kev tsim cov excavators.
Ntau- thoob excavators kuj muaj keeb kwm ntau tshaj 100 xyoo. Fabkis tau tsim lub ntiaj teb thawj zaug thiab paub tab ntau yam - thoob excavator hauv xyoo 1860 rau txoj haujlwm Suez Canal excavation. Xyoo 1889, Tebchaws Meskas tau tsim ntau lub- thoob trencher muaj peev xwm khawb trenches 0.29 meters dav thiab 1.4 meters tob. Nyob rau hauv lub xyoo pua puv 19, lub thoob log excavators tau dav siv nyob rau hauv lignite mining nyob rau hauv lub teb chaws Yelemees, thiab los ntawm 1958, txhua lub thoob muaj peev xwm mus txog 3,600 litres. Xyoo 1977, Lub Tebchaws Yelemees sab hnub poob tau tsim lub thoob ntiaj teb loj tshaj plaws lub log excavator, nrog kev tsim khoom ntawm 240,000 meter{19}}hnub.
Thaum pib, excavators tau ua manually. Los ntawm lawv qhov kev tsim kho rau xyoo 2013, ntau dua 130 xyoo dhau los, lawv tau dhau los ua qhov kev loj hlob zuj zus los ntawm chav - lub thoob lub log excavators rau hluav taws xob thiab sab hauv combustion engine -powered log excavators, thiab thaum kawg kom tag nrho tsis siv neeg hydraulic excavators siv tshuab mechatronics. Thawj hydraulic excavator tau ntse tsim los ntawm lub Hoobkas Poclain hauv Fabkis. Raws li kev siv tshuab hydraulic, hauv xyoo 1940, hydraulic backhoe excavators mounted rau tsheb laij teb tau tsim. Nyob rau hauv 1951, thawj tag nrho hydraulic backhoe excavator twb launched los ntawm lub Hoobkas Poclain nyob rau hauv Fabkis, qhib tag nrho cov tshiab possibilities nyob rau hauv excavator technology kev loj hlob. Thaum ntxov thiab nruab nrab- xyoo 1950, rub tag nrho - kev sib hloov hydraulic excavators thiab taug qab tag nrho hydraulic excavators tau ua tiav. Thaum ntxov qauv hydraulic excavators siv hydraulic technology los ntawm aircraft thiab tshuab cuab yeej, tsis muaj hydraulic Cheebtsam haum rau ntau yam excavator kev khiav hauj lwm tej yam kev mob. Kev tsim khoom zoo tsis ruaj khov, thiab cov khoom seem tsis tiav. Txij xyoo 1960 mus, hydraulic excavators nkag mus rau theem ntawm kev nce qib thiab kev loj hlob sai. Tus naj npawb ntawm cov tuam txhab excavator thiab cov khoom lag luam tau nce sai hauv ntau lub tebchaws, thiab ntau lawm tau nce. Nyob nruab nrab ntawm xyoo 1968 thiab 1970, hydraulic excavator ntau lawm suav txog 83% ntawm tag nrho cov khoom siv excavator, nce mus txog 100%. Thawj- tiam excavators: Lub advent ntawm hluav taws xob motors thiab combustion engines muab excavators nrog advanced thiab haum fais drives, ua rau muaj tshwm sim ntawm ntau yam excavator khoom. Thawj qhov hluav taws xob excavator tau tshwm sim hauv xyoo 1899. Tom qab Tsov Rog Thoob Ntiaj Teb thib 1, lub tshuab hluav taws xob kuj tau siv rau hauv excavators; cov diesel cav (los yog hluav taws xob lub cev muaj zog) tsav tshuab excavators yog thawj tiam ntawm excavators. Thib ob- tiam excavators: Nrog rau kev siv dav siv tshuab hydraulic, excavators muaj ntau lub suab thiab cov khoom siv sib kis tau zoo. Hydraulic kis tau tus mob hloov mechanical kis tau tus mob yog ib tug loj leap rau pem hauv ntej nyob rau hauv excavator technology. Thawj hydraulic excavator yug nyob rau hauv lub teb chaws Yelemees xyoo 1950. Lub hydraulicization ntawm mechanical kis tau tus mob yog lub thib ob tiam ntawm excavators. Lub cim thib peb ntawm excavators: Kev siv dav siv hauv tshuab hluav taws xob, tshwj xeeb tshaj yog siv tshuab computer, tau ua kom cov excavators muaj kev tswj hwm lub tshuab, thiab tseem tau tsav txoj kev loj hlob ntawm excavators mus rau kev ua haujlwm siab, automation, thiab kev txawj ntse. Lub tswv yim ntawm mechatronics tau tshwm sim nyob ib ncig ntawm 1965, thiab nws txoj kev saws me nyuam hauv huab hwm coj- tsim tawm hydraulic excavators pib nyob rau xyoo 1985, feem ntau rau kev txuag hluav taws xob. Kev siv hluav taws xob ntawm excavators yog lub cim ntawm peb tiam. Excavator manufacturers tuaj yeem muab faib ua plaub hom. Cov khoom lag luam txawv teb chaws tseem ua tus thawj coj hauv kev lag luam excavator, suav txog ntau dua 70% ntawm kev ua lag luam. Cov hom lag luam hauv tsev feem ntau tsom rau cov me me thiab nruab nrab- cov excavators loj, tab sis lawv cov kev lag luam feem ntau tau nce zuj zus, nce los ntawm 3.6% xyoo-on-xyoo xyoo 2012.
