I. Tsim:

A. Backhoe Loader:
1. Lub backhoe loader yog lub tshuab muaj ntau yam uas sib txuas cov peev txheej ntawm lub tsheb laij teb thiab lub tsheb thauj khoom pem hauv ntej.
2. Nws muaj ib lub tsheb laij teb zoo li lub tsheb nrog lub thoob loader rau pem hauv ntej thiab backhoe txuas rau tom qab.
3. Lub backhoe txuas yog siv rau kev khawb, trenching, thiab excavating hauj lwm.

B. Excavator:
1. Lub tshuab excavator yog lub tshuab ua haujlwm hnyav tsim tshwj xeeb rau kev khawb thiab khawb.
2. Nws nta lub rotating platform hu ua lub tsev, uas yog mounted rau lem los yog log.
3. Lub tsev txhawb nqa lub boom, stick, thiab thoob, uas yog siv rau kev khawb, nqa, thiab cov khoom txav.

II.Kev ua haujlwm:

A. Backhoe Loader:
1. Lub thoob loader nyob rau pem hauv ntej ntawm lub backhoe loader yog siv rau kev thauj khoom thiab thauj khoom xws li av, gravel, thiab khib nyiab.
2. Lub backhoe txuas rau sab nraub qaum yog siv rau kev khawb trenches, excavating foundation, thiab ua lwm yam hauj lwm hauv av.
3. Lub backhoe txuas tuaj yeem tig 180 degrees, tso cai rau kev hloov pauv ntau dua thiab ua haujlwm.

B. Excavator:
1. Ib qho excavator feem ntau yog siv rau kev khawb thiab khawb av.
2. Nws muaj peev xwm khawb qhov tob trench, excavating loj ntim ntawm av, thiab nqa cov khoom hnyav.
3. Lub tsev rotating tso cai rau tus neeg teb xov tooj mus txog thaj chaw uas nyuaj rau kev nkag mus nrog lwm lub tshuab.

III.Daim ntawv thov:

A. Backhoe Loader:
1. Backhoe loaders feem ntau yog siv rau hauv kev tsim kho cov haujlwm uas yuav tsum muaj peev xwm khawb thiab thauj khoom.
2. Lawv feem ntau siv nyob rau hauv nroog qhov chaw uas muaj qhov txwv thiab maneuverability yog qhov tseem ceeb.
3. Backhoe loaders kuj tseem siv rau hauv kev tsim kho vaj tse, kev saib xyuas txoj kev, thiab kev ua liaj ua teb.

B. Excavator:
1. Excavators tau siv dav hauv kev tsim kho loj xws li kev tsim vaj tsev, kev tsim kho, thiab kev tsuas.
2. Lawv kuj tau siv rau hauv cov phiaj xwm demolition los rhuav tshem cov qauv thiab tshem tawm cov khib nyiab.
3. Excavators yog ntau yam tshuab uas tuaj yeem nruab nrog ntau yam txuas xws li hydraulic hammers, grapples, thiab augers rau kev siv sib txawv.

Hauv kev xaus, thaum ob qho tib si backhoe loaders thiab excavators yog cov tshuab tseem ceeb hauv kev tsim kho kev lag luam, lawv muaj qhov sib txawv ntawm kev tsim, kev ua haujlwm, thiab kev siv.Backhoe loaders yog ntau yam tshuab uas sib txuas lub peev xwm ntawm lub tsheb laij teb thiab lub tsheb thauj khoom pem hauv ntej nrog lub backhoe txuas rau kev khawb av.Ntawm qhov tod tes, excavators yog cov tshuab tshwj xeeb tsim tshwj xeeb rau kev khawb thiab khawb cov dej num hnyav.Kev nkag siab txog qhov sib txawv no tuaj yeem pab cov kws tsim kho xaiv lub tshuab zoo rau lawv cov kev xav tau tshwj xeeb.
