I. Design:

A. Umthwalo we-Backhoe:
1. Isilayidi sangemuva ngumshini ohlukahlukene ohlanganisa amakhono ogandaganda kanye nomthwalo ongaphambili.
2. Siqukethe iyunithi enjenge-tractor enebhakede lomthwalo ngaphambili kanye nokunamathiselwa kwe-backhoe ngemuva.
I-3. Okunamathiselwe kwe-backhoe kusetshenziselwa ukumba, ukunqamula, kanye nokumba imisebenzi.

B. Excarerator:
1. I-Excavator ngumshini onesindayo owenzelwe ngqo imisebenzi yokumba kanye nemisebenzi yokumba.
2. Ifaka ipulatifomu ejikelezayo ebizwa ngokuthi yiNdlu, ebekwe kumathrekhi noma kumasondo.
I-3. Indlu isekela i-boom, induku nebhakede, esetshenziselwa ukumba, ukuphakamisa, nokuhambisa izinto zokwakha.

II. Ukusebenza:

A. Umthwalo we-Backhoe:
1
2
I-3. Ukunamathiselwa kwe-backhoe kungajikelezwa ama-degree angama-180, okuvumela ukuguquguquka okukhulu nokuqondisa.

B. Excarerator:
1. I-Excator isetshenziselwa ukumba okusindayo kwemisebenzi yokumba kanye nemisebenzi yokumba.
2. Iyakwazi ukumba imisele ejulile, yemba inhlabathi enkulu, nokuphakamisa izinto ezisindayo.
I-3. Indlu ejikelezayo ivumela opharetha ukuthi afinyelele ezindaweni ezinzima ukufinyelela kuzo neminye imishini.

III. Izicelo:

A. Umthwalo we-Backhoe:
1. Ukulayisha kwangemuva kuvame ukusetshenziswa kumaphrojekthi wokwakha adinga ukumba nokulayisha amakhono.
2. Zivame ukusetshenziselwa ezindaweni zasemadolobheni lapho isikhala sinqunyelwe futhi i-maneuverability ibalulekile.
3. Abathengisi be-Backhoe baphinde basebenzise ekuhlolweni komhlaba, ukulungiswa kwemigwaqo, kanye nezinhlelo zokusebenza zezolimo.

B. Excarerator:
1. Abahloli basetshenziswa kabanzi kumaphrojekthi wokwakha amakhulu njengokwakha ukwakha umgwaqo, kanye nezimayini.
2. Baphinde basetshenziswe kumaphrojekthi wokudiliza ukudiliza izakhiwo futhi asuse imfucumfucu.
I-3. Abahloli banemishini eguquguqukayo engafakwa ngokunamathiselwe okuhlukahlukene njengezando ze-hydraulic, izithelo, kanye nama-auger ngezicelo ezihlukile.

Ekuphetheni, ngenkathi bobabili abalayisha be-backhoe nabavubukuli imishini ebalulekile embonini yezokwakha, banomehluko ohlukile ngokuya ngokwakhiwa, ukusebenza, kanye nezicelo. Abathengisi be-Backhoe banemishini eguquguqukayo ehlanganisa amakhono ogandaganda kanye nomthwalo ongaphambili onama-backhoe okunamathiselwe kwemisebenzi yokumba. Ngakolunye uhlangothi, abakwa-Excagelators imishini ekhethekile eyenzelwe ngqo ukumba okusindayo kwemisebenzi yokumba umthwalo. Ukuqonda lokhu kwehluka kungasiza ochwepheshe bokwakha bakhethe umshini ofanele ngezidingo zabo ezithile.
