Umhlinzeki wemishini yokwakha wezixazululo zemishini yokwakha iminyaka engama-30.
Ekwakhiweni, ukukhetha i-excavator encane enesisindo esifanele kubalulekile ekusebenzeni kahle kwephrojekthi nokuphepha. Isisindo sinomthelela ekuzinzeni komshini, ukulawuleka, kanye nokufaneleka kwemisebenzi ethile. Isibonelo, ama-excavator amancane alula alungele amaphrojekthi angaphakathi noma izindawo ezithambile lapho ukucindezela komhlaba kufanele kuncishiswe. Ngokuphambene, amamodeli asindayo anikeza amandla okumba athuthukisiwe nokuzinza, okuwenza afanelekele imisebenzi enzima kakhulu njengokugenca noma ukuphakamisa izinto ezisindayo. Ukuqonda ubudlelwano phakathi kwesisindo se-mini excavator nendawo yokwakha kuqinisekisa ukusebenza kahle futhi kunciphisa ubungozi bokulimala kwesayithi noma ukwehluleka kwemishini.
Isisindo se-mini excavator sinqunywa izici ezihlukahlukene, okuhlanganisa ifilosofi yedizayini yomkhiqizi, ubukhulu, izinto ezisetshenziswayo, kanye nokuma kwemakethe. Abakhiqizi balinganisela isidingo sokuqina nokusebenza kanye nesidingo sokubumbana nokusebenza kahle. Ukukhethwa kwezinto ezibonakalayo, njengensimbi ephezulu-amandla noma ama-alloys angasindi, kuthinta isisindo sonke. Ukwengeza, ukufakwa kwezici ezifana namakhebhu avaliwe, amasistimu asebenza ngogesi athuthukisiwe, nezinanyathiselwa ezikhethekile kungakhuphula isisindo somshini. Ukuma kwemakethe nakho kunendima; amamodeli aklanyelwe imisebenzi esindayo ngokuvamile asindayo ukuthwala izinjini ezinamandla nezingxenye eziqinile.
Izindawo zokwakha zinethonya kakhulu isisindo esidingekayo sama-excavators amancane. Ezilungiselelweni zasemadolobheni ezinendawo elinganiselwe, imishini elula ikhethwa ngenxa yokukhululeka kwayo kwezokuthutha kanye nomthelela omncane ophansi. Isibonelo, imodeli ye-Mini Excavator 1 ton ifanele ukuhlelwa kwezindawo zokuhlala noma ukulungiswa kwangaphakathi. Ngokuphambene, iziza zokwakha zasemakhaya noma ezinkulu zingase zidinge ukumba ama-mini ukuze kusingathwe imisebenzi emikhulu kanye nezindawo ezingalingani. Ukukhetha phakathi kwamathrekhi enjoloba kanye nensimbi mini excavator nakho kuncike endaweni ezungezile; amathrekhi enjoloba athambile ezindaweni eziphelile, kuyilapho amathrekhi ensimbi anikeza ukuqina okungcono ezindaweni ezimbi.
Izingxenye eziningana zifaka isandla esisindweni sonke se-excavator encane. Inqola yangaphansi, okuhlanganisa amathrekhi nezinjini zokushayela, yengeza isisindo esikhulu, ikakhulukazi uma kusetshenziswa amathrekhi ensimbi ukuze aqine. Ubukhulu nomthamo webhakede le-mini excavator nakho kunendima; amabhakede amakhulu andisa isisindo somshini kodwa athuthukisa ukukhiqiza. Ukwengeza, ukufakwa kwekhebhu enokulawulwa kwesimo sezulu, amasistimu okulawula athuthukile, nezici zokuphepha ezifana nezakhiwo zokuvikela i-rollover (ROPS) kwengeza isisindo. Abakhiqizi kufanele balinganisele lezi zici ukuze bakhiqize i-excavator encane ehlangabezana nezimfuneko zokusebenza ngaphandle kokudlula imikhawulo yesisindo sokuthutha nokusebenza.
Injini kanye nesistimu ye-hydraulic imaphakathi ekusebenzeni kwe-mini excavator futhi inomthelela kakhulu isisindo sayo. Izinjini ezinamandla kakhulu, ezidingekayo emisebenzini enzima, zisinda futhi zidinga amathangi amakhulu kaphethiloli, okunikela esisindweni sisonke. Amasistimu we-hydraulic athuthukisiwe, ahlinzeka ngokulawula okunembile kanye nekhono lokusebenzisa okunamathiselwe kwe-mini excavator ehlukahlukene, futhi engeza isisindo ngenxa yezingxenye ezengeziwe njengamaphampu, ama-valve, namapayipi. Isibonelo, i-excavator encane efakwe isistimu ye-hydraulic enamandla amakhulu ingaphatha okunamathiselwe njengama-auger noma ama-breaker kodwa izoba nzima kunemodeli eyisisekelo edizayinelwe imisebenzi elula yokumba.
Izinto ezisetshenziswa ekwakheni izingxenye ezihlukahlukene ze-excavator encane zithonya isisindo nokusebenza kwayo. Insimbi enamandla amakhulu ivamise ukusetshenziselwa izingxenye zesakhiwo njenge-boom nengalo ukumelana nemithwalo esindayo, okwandisa isisindo somshini. Ngokuphambene, ukusebenzisa izinto ezingasindi njenge-aluminium ezingxenyeni ezingezona ezakhiwe kunganciphisa isisindo ngaphandle kokuphazamisa amandla. Ukukhethwa kwezinto zokufakwa, njengebhakede le-mini excavator nezinamathiselo, nakho kuthinta isisindo. Isibonelo, ibhakede elisindayo eliklanyelwe ukumba amatshe lizoba nesisindo esingaphezu kwebhakede elijwayelekile elisetshenziselwa ukumba okuvamile, okunomthelela kusisindo esiphelele nebhalansi yomshini.
Ukuqonda ukuhluka kwesisindo phakathi kwamamodeli e-mini excavator ahlukene kusiza ekukhetheni umshini ofanele wemisebenzi ethile. Nazi izibonelo:
I-Kobelco SK17SR-6E: 3,681 lbs - Ifanele izikhala eziqinile nemisebenzi elula.
I-Kobelco SK35SR-7: 9,000 lbs - Inikeza ibhalansi phakathi kosayizi ohlangene nokusebenza okunamandla.
I-Komatsu PC55MR-5: 12,295 lbs - Idizayinelwe imisebenzi enzima kakhulu enozinzo oluthuthukisiwe.
I-Kubota KX018-4: 3,935 lbs - Ilungele amaphrojekthi amancane adinga ukuguqulwa.
I-Mustang 350Z NXT2: 5,919 lbs – Ihlinzeka ngokuguquguquka kwezinhlelo zokusebenza ezihlukahlukene zokwakha.
I-New Holland E30C: 6,922 lbs - Ibhalansi isisindo kanye nokusebenza kwamaphrojekthi aphakathi nendawo.
Ikesi CX60C: 13,760 lbs - Ifanele imisebenzi esindayo edinga okokusebenza okuqinile.
I-Takeuchi TB240: 8,570 lbs - Inikeza ukusebenza okuqinile ngedizayini ehlangene.
Lezi zibonelo zibonisa ububanzi bezisindo ze-mini excavator ezitholakalayo, ezivumela izinqumo ezinolwazi ngokusekelwe ezidingweni zephrojekthi kanye nezimo zesayithi.
