Tsis yog, ** Backhoe ** thiab ** Cov excavators ** yog ** tsis zoo li qub **, txawm tias lawv yog ob tus khawb tshuab siv hauv kev tsim kho. Ntawm no yog kev tawg ntawm lawv qhov sib txawv tseem ceeb:
1. Tsim & Qauv
- backhoe (backhoe loader):
- Ua ke ob qho cuab yeej: pem hauv ntej-mounted loader thoob (zoo li lub tsheb nrau av) thiab lub nraub qaum-mounted backhoe caj npab (rau kev khawb).
- Me me, kev cog lus me dua, thiab kev ua haujlwm heev.
- Feem ntau mounted ntawm cov log lossis cov log tsheb me rau txoj kev mus ncig.
- Excavator:
- Ib lub tshuab ib-lub hom phiaj nrog tus cab khiav (360 degree), ntev ntev caj npab (boom \/ pas), thiab lub thoob.
- Qhov loj dua, hnyav dua, thiab tsim los txhawm rau khawb khawb lossis hnyav.
- Feem ntau lem (zoo li tank treads) rau kev ruaj khov ntawm strechar.
2. Thawj siv
- Backhoe:
- Qhov zoo tagnrho rau me me rau nruab nrab txoj haujlwm: khawb trenches, nqa cov ntaub ntawv teeb pom kev, thauj khoom, lossis qhab nia.
- Ntau yam rau cov haujlwm sib xyaw (piv txwv li, kev tsim kho hauv nroog, kev tsim kho av).
- Excavator:
- Ua rau kev ntsuas hnyav-ua haujlwm kos: kev sib sib zog khawb, kev txiav txim siab, tsuas, lossis loj-teev equellmoving.
- Siv tau cov ntaub ntawv tshwj xeeb tshwj xeeb (piv txwv li, cov rauj uas muag khoom noj mov (me me).
3. Muaj peev xwm
- Backhoe:
- wheeled versions tuaj yeem tsav ntawm txoj kev (tsis muaj tsheb thauj khoom xav tau).
- Zoo dua rau cov chaw nres nruj (piv txwv li, cov chaw hauv nroog).
- Excavator:
- Taug qab raws kev ruaj khov ntawm cov muag muag \/ av nkos tab sis qeeb qeeb.
- Yuav tsum muaj qhov chaw tsheb ciav hlau mus rau kev ncua ntev.
4. Terminology Confusion
- Hauv qee thaj tsam, "backhoe" yog qhov yuam kev siv los piav qhia cov excavators.
- Ib qho ntsiab lus tseem ceeb: tus backhoe yog ntau-ua kom muaj zog loader \/ digger, thaum ib lub tshuab khawb thiab siv ntau dua.
Ntsiab lus:
- Xav tau versatility thiab mus ncig? → backhoe.
- Yuav tsum muaj zog raw thiab qhov tob? → excavator.
