Umthengisi wezixhobo zokwakha izisombululo zoomatshini bokwakha kangangeminyaka engama-30.
Ekwakhiweni, ukukhetha i-excavator encinci enobunzima obufanelekileyo kubalulekile ekusebenzeni kakuhle kweprojekthi kunye nokhuseleko. Ubunzima buchaphazela ukuzinza komatshini, ukulawuleka, kunye nokufaneleka kwemisebenzi ethile. Umzekelo, ii-excavators ezincinci zilungele iiprojekthi zangaphakathi okanye iindawo ezithambileyo apho uxinzelelo lomhlaba kufuneka luncitshiswe. Ngokuchaseneyo, iimodeli ezinzima zibonelela ngezakhono zokwemba ezongeziweyo kunye nokuzinza, zizenza zilungele imisebenzi enzima ngakumbi njengokugrumba okanye ukuphakamisa izinto ezinzima. Ukuqonda ubudlelwane phakathi kobunzima be-excavator encinci kunye nemeko yokwakha iqinisekisa ukusebenza kakuhle kunye nokunciphisa umngcipheko womonakalo wesayithi okanye ukusilela kwezixhobo.
Ubunzima be-excavator encinci bumiselwa yimiba eyahlukeneyo, kubandakanya ifilosofi yoyilo lomenzi, imilinganiselo, imathiriyeli esetyenzisiweyo, kunye nokuma kwemarike. Abavelisi balinganisela imfuno yokuqina kunye nokusebenza kunye nemfuno yokubumbana kunye nokusebenza kakuhle. Ukukhethwa kwezinto eziphathekayo, ezifana nentsimbi ephezulu okanye i-alloys elula, ichaphazela ubunzima obupheleleyo. Ukongeza, ukufakwa kweempawu ezinje ngeekhabhi ezivaliweyo, iinkqubo zehydraulic eziphambili, kunye nezinamathiselo ezikhethekileyo kunokunyusa ubunzima bomatshini. Ukuma kwemarike kukwadlala indima; iimodeli ezilungiselelwe imisebenzi enzima zidla ngokuba nzima ukuhlalisa iinjini ezinamandla kunye nezinto ezomeleleyo.
Ubume bokwakha bunempembelelo enkulu kubunzima obufunekayo bama-excavators amancinci. Kwiindawo ezisezidolophini ezinendawo elinganiselweyo, oomatshini abalula bakhethwa ngokukhululeka kwabo kwezothutho kunye nempembelelo encinci yomhlaba. Ngokomzekelo, imodeli ye-Mini Excavator ye-toni ye-1 ifanelekile kwindawo yokuhlala okanye ukulungiswa kwangaphakathi. Ngokuchaseneyo, iziza zokwakha zasemaphandleni okanye ezinkulu zinokufuna abembi bemigodi abanzima ukuze bajongane nemisebenzi emikhulu kunye nemihlaba engalinganiyo. Ukukhetha phakathi kweerabha kunye neengoma ze-mini excavator mini nazo zixhomekeke kwindalo; Iingoma zerabha zithambile kumphezulu ogqityiweyo, ngelixa iingoma zentsimbi zinokomelela ngcono kwiindawo ezirhabaxa.
Amacandelo amaninzi afaka isandla kubunzima obupheleleyo be-excavator encinci. I-undercarriage, kubandakanywa iingoma kunye neenjini zokuqhuba, yongeza ubunzima obuninzi, ngakumbi xa usebenzisa iingoma zentsimbi zokuqina. Ubungakanani kunye nomthamo webhakethi encinci ye-excavator nayo idlala indima; ii-emele ezinkulu zonyusa ubunzima bomatshini kodwa zongeza imveliso. Ukongezelela, ukufakwa kwe-cab kunye nokulawulwa kwemozulu, iinkqubo zokulawula eziphambili, kunye neempawu zokhuseleko ezifana nezakhiwo zokukhusela i-rollover (ROPS) yongeza ubunzima. Abavelisi kufuneka balungelelanise le miba ukuvelisa i-excavator encinci ehlangabezana neemfuno zokusebenza ngaphandle kokudlula imilinganiselo yobunzima bokuthutha kunye nokusebenza.
I-injini kunye ne-hydraulic system zingundoqo ekusebenzeni kwe-excavator encinci kwaye ichaphazela kakhulu ubunzima bayo. Iinjini ezinamandla ngakumbi, eziyimfuneko kwimisebenzi efunwayo, zinzima kwaye zifuna iitanki zepetroli ezinkulu, ezinegalelo kubunzima bubonke. Iinkqubo eziphezulu ze-hydraulic, ezibonelela ngolawulo oluchanekileyo kunye nokukwazi ukusebenzisa izinamathiselo ezahlukeneyo ze-excavator mini, nazo zongeza ubunzima ngenxa yezinto ezongezelelweyo ezifana neepompo, iivalve, kunye ne-hoses. Ngokomzekelo, i-excavator encinci exhotywe nge-high-capacity hydraulic system inokusingatha izinamathiselo ezifana ne-augers okanye i-breakers kodwa iya kuba nzima kunemodeli eyisiseko eyenzelwe imisebenzi elula yokumba.
Izinto ezisetyenziselwa ukwakha iindawo ezahlukeneyo ze-excavator encinci zinefuthe kubunzima bayo kunye nokusebenza kwayo. Intsimbi ephezulu yokuqina iqhele ukusetyenziswa kumacandelo olwakhiwo njenge-boom kunye nengalo ukumelana nemithwalo enzima, ukwandisa ubunzima bomatshini. Ngokwahlukileyo, ukusebenzisa imathiriyeli ekhaphukhaphu efana ne-aluminiyam kumalungu angengolwakhiwo kunokunciphisa ubunzima ngaphandle kokuthomalalisa amandla. Ukukhethwa kwezinto zokufakelwa, ezifana nebhakethi ye-mini excavator kunye neziqhotyoshelweyo, nazo zichaphazela ubunzima. Ngokomzekelo, ibhakethi elinzima elenzelwe ukumba ilitye liya kuba nesisindo esingaphezu kwebhakethi eliqhelekileyo elisetyenziselwa ukumba jikelele, ukuchaphazela ubunzima kunye nokulinganisela komatshini.
Ukuqonda ukuhluka kobunzima phakathi kweemodeli ezahlukeneyo ze-mini excavator kunceda ekukhetheni umatshini ofanelekileyo kwimisebenzi ethile. Nantsi eminye imizekelo:
I-Kobelco SK17SR-6E: 3,681 lbs - Ifanelekile kwiindawo eziqinileyo kunye nemisebenzi yokukhanya.
