Zipangizo zokumba ndi zida zofunika kwambiri m'makampani omanga ndi migodi. Zimagwiritsidwa ntchito pokumba, kugwetsa ndi ntchito zina zolemetsa. Gawo lofunika kwambiri la chitsulo chofukula ndi nsapato zoyendera. Nsapato zoyendera ndizofunikira kwambiri popereka mphamvu ndi kukhazikika kwa chitsulo chofukula, makamaka m'malo ovuta.

Mapepala a rabara ofukula zinthu zakalendi njira yabwino kwambiri m'malo mwa ma track pad achitsulo achikhalidwe. Amapereka zabwino zosiyanasiyana zomwe zimawapangitsa kukhala chisankho chodziwika bwino pakati pa akatswiri omanga. Nazi zabwino zogwiritsa ntchito ma rabara pa ma excavator:

1. Kuchepetsa kuwonongeka kwa nthaka: Poyerekeza ndi nsapato zachitsulo, nsapato za rabara zimakhala ndi mphamvu yofewa pansi. Zimagawa kulemera kwa chofukula mofanana, zomwe zimathandiza kuchepetsa kuwonongeka kwa malo omangira kapena malo ozungulira. Izi ndizofunikira kwambiri pogwira ntchito pamalo osavuta monga udzu, misewu, kapena phula.

2. Kugwira bwino ntchito: Ma rabara amapereka mphamvu yogwira ntchito bwino ngakhale m'malo otsetsereka kapena amatope. Izi zimathandiza kuti chofukula chikhale chokhazikika komanso chimachepetsa chiopsezo chotsetsereka kapena kutsekeka, zomwe pamapeto pake zimawonjezera ntchito yabwino pamalo ogwirira ntchito.

3. Ntchito yochepetsera phokoso:chofukula mapadi a rabarakuchepetsa kwambiri phokoso lomwe limapangidwa pamene chofukula chikuyenda. Izi zimapindulitsa wogwiritsa ntchito komanso malo ozungulira, makamaka m'malo okhala anthu kapena m'mizinda komwe kuipitsa phokoso ndi vuto.

4. Nthawi yayitali yogwira ntchito: Poyerekeza ndi nsapato zachitsulo, nsapato za rabara sizimavutika ndi dzimbiri komanso kutha. Zimalimbananso ndi ming'alu, kung'ambika ndi kuwonongeka kwina, zomwe zimawonjezera nthawi yawo yogwira ntchito komanso kuchepetsa ndalama zokonzera.

5. Kusinthasintha: Pedi ya rabara ndi yoyenera mitundu yosiyanasiyana ya ma excavator ndipo imatha kuyikidwa ndikuchotsedwa mosavuta ngati pakufunika. Imapezeka mu kukula ndi mawonekedwe osiyanasiyana kuti igwirizane ndi mitundu yosiyanasiyana ndi momwe imagwirira ntchito.

Powombetsa mkota,mapepala oyendetsera njanjiamapereka zabwino zosiyanasiyana kuphatikizapo kuchepetsa kuwonongeka kwa nthaka, kukonza mphamvu yogwirira ntchito, kugwira ntchito mopanda phokoso, kukhala ndi moyo wautali komanso kusinthasintha. Posankha ma rabara, akatswiri omanga amatha kukonza magwiridwe antchito a ma archer awo pomwe akuchepetsa mphamvu zawo pa chilengedwe. Chifukwa chake, kuyika ndalama mu rabara wabwino ndi chisankho chomwe chingakhale ndi zotsatira zabwino pakupanga ndi kukhazikika kwa malo anu ogwirira ntchito.
