Thawj - tiam excavators: Lub advent ntawm hluav taws xob motors thiab combustion engines muab excavators nrog advanced thiab haum electric actuators, ua rau txoj kev loj hlob 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) uas tau tsav txhua yam excavators yog thawj tiam ntawm excavators.
Thib ob- tiam excavators: Kev siv dav dav ntawm cov tshuab hydraulic muab cov tshuab excavators nrog ntau qhov kev tshawb fawb thiab tsim cov khoom sib kis. 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.
Thib peb- tiam excavators: Kev siv dav siv tshuab hluav taws xob, tshwj xeeb tshaj yog siv tshuab computer, tau muab excavators automated tswj systems, propelling lawv mus rau kev ua tau zoo, automation, thiab txawj ntse. Lub tswv yim ntawm mechatronics tau tshwm sim nyob ib puag ncig xyoo 1965, thaum nws 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 lub cim thib peb ntawm excavators.
