Excavators tuaj yeem faib ua ob hom yooj yim raws li lawv txoj kev taug kev: crawler excavators thiab wheeled excavators.
1. Crawler excavator
Qhov no yog hom siv ntau tshaj plaws thiab siv dav, nrog lub chassis nruab nrog ob qhov txuas txuas ntxiv, zoo ib yam li tso tsheb hlau luam. Qhov kev tsim no muab nws ntau yam zoo:
Zoo heev stability thiab traction: Cov lem faib qhov hnyav ntawm lub tshuab hla ib cheeb tsam loj, uas ua rau cov av tsis tshua muaj siab rau hauv av. Qhov no ua rau nws ua haujlwm ruaj khov ntawm qhov muag muag, rugged, lossis tsis sib xws xws li av nkos, xuab zeb, thiab qhov chaw siab tshaj yam tsis yooj yim los nag.
Lub peev xwm ua haujlwm hauv tsev muaj peev xwm: Vim nws lub platform ruaj khov, crawler excavators ntawm tib theem feem ntau muaj peev xwm khawb thiab nqa ntau dua li lub log excavators.
Qhov tsis zoo tseem ceeb: Nws txoj kev txav ceev ntawm qhov chaw tsim kho qeeb heev, thiab cov lem tuaj yeem ua rau txoj kev paved puas. Thaum hloov mus deb ntawm txoj kev pej xeem, cov tsheb ciav hlau yuav tsum tau siv rau kev thauj mus los.
2. Log excavator
Hom chassis no yog nruab nrog cov log tsheb, zoo li lub tsheb thauj khoom. Nws lub ntsiab kom zoo dua yog nyob rau hauv mobility:
Kev txav chaw siab heev: Nws tuaj yeem taug kev ntawm kev kub ceev ntawm txoj kev pav (xws li txoj kev hauv nroog thiab txoj kev loj) zoo li lub tsheb, yooj yim hloov ntawm ntau qhov chaw tsim khoom tawg thoob plaws hauv nroog yam tsis tas yuav muaj tsheb thauj mus los, txuag sijhawm thiab nqi.
Txoj kev phooj ywg: Roj hmab log tsheb yuav tsis puas asphalt lossis qhob txoj kev, ua rau lawv zoo heev rau kev tsim kho hauv nroog, kev saib xyuas, thiab kev ua haujlwm ntsuab.
Qhov tsis zoo tseem ceeb: Yooj yim rau plam lossis dab dej ntawm cov av mos lossis av nkos, nrog kev ruaj ntseg tsis zoo. Thaum nqa tawm hnyav excavation los yog lifting hauj lwm, nws yog ib qhov tsim nyog los txo qis hydraulic txhawb ob txhais ceg (stabilizers) kom ruaj ntseg lub cev ntawm lub tshuab kom muaj kev ruaj ntseg.
Cov ntsiab lus sib piv cov ntsiab lus tseem ceeb: Koj tuaj yeem suav tias tsuas yog taug qab cov excavators li "tawm-cov kws paub txog kev" tsom mus rau kev ua haujlwm hnyav thiab muaj peev xwm taug qab cov av hnyav; Thiab xav txog cov log tsheb excavators li "cov kws tshaj lij hauv nroog sai" tau tsom mus rau kev nrawm nrawm thiab ntau- taw tes ncig hauv kev sib txuas hauv kev sib txuas. Kev xaiv hom feem ntau yog nyob ntawm seb qhov project twg muaj qhov xav tau ceev dua rau qhov chaw nkag mus tau thiab kev txav mus los.
