Thawj tiam ntawm excavators: qhov tshwm sim ntawm hluav taws xob motors thiab combustion engines nyob rau hauv excavators muaj advanced thiab haum cov khoom siv hluav taws xob, yog li ntau yam excavator khoom tau yug los ib tug tom qab. Xyoo 1899, thawj lub tshuab hluav taws xob excavator tau tshwm sim. Tom qab Tsov Rog Thoob Ntiaj Teb thib 1, cov tshuab hluav taws xob kuj tau siv rau hauv cov tshuab excavators. Qhov no diesel cav (los yog hluav taws xob lub cev muaj zog) tsav txhua yam excavator yog thawj tiam ntawm excavators.
Qhov thib ob tiam ntawm excavators: Nrog rau kev siv ntau ntawm hydraulic technology, lub excavator muaj ntau scientific thiab siv kis tau tus mob ntaus ntawv, thiab hydraulic kis tau tus mob es tsis txhob ntawm mechanical kis tau tus mob yog ib tug loj leap nyob rau hauv excavator technology. Nyob rau hauv 1950 lub teb chaws Yelemees thawj hydraulic excavator tau yug los. Hydraulic mechanical kis tau tus mob yog thib ob tiam ntawm excavators.
Lub cim thib peb ntawm excavators: Kev siv dav hauv kev siv tshuab hluav taws xob, tshwj xeeb tshaj yog siv tshuab computer, ua rau lub tshuab excavator kom muaj kev tswj xyuas qhov system, thiab tseem ua rau lub excavator tsim nyob rau hauv cov kev taw qhia ntawm kev ua haujlwm siab, automation thiab kev txawj ntse. Lub germination ntawm mechatronics tshwm sim nyob ib ncig ntawm 1965, thiab kev saws mechatronics technology ntawm loj-tsim hydraulic excavators yog nyob ib ncig ntawm 1985, thaum lub ntsiab lub hom phiaj yog kom txuag tau lub zog. Excavator electronics yog lub cim ntawm peb tiam ntawm excavators.
