Ii-graveer ezincinci zezinye zezixhobo ezikhula ngokukhawuleza, kwaye ukuthandwa kwazo kubonakala kuqhubeka kusanda. Ngokwedatha evela kwi-Off-Highway Research, ukuthengiswa kwe-graveer ezincinci kwihlabathi liphela kufikelele kwinqanaba eliphezulu kunyaka ophelileyo, kudlule iiyunithi ezingama-300,000.
Ngokwesiko, iimarike eziphambili zee-micro-excavators beziziilizwe eziphuhlileyo, ezifana neJapan neNtshona Yurophu, kodwa ukuthandwa kwazo kumazwe amaninzi asakhasayo kuye kwanda kwiminyaka elishumi edlulileyo. Eyona idumileyo kwezi yiTshayina, okwangoku eyimarike enkulu kunazo zonke yee-mini-excavators emhlabeni.
Xa ucinga ukuba oomashini abancinci bokumba izinto banokuthi bathathe indawo yomsebenzi wezandla, ngokuqinisekileyo akukho kunqongophala kwabasebenzi kumazwe anabemi abaninzi ehlabathini. Oku kusenokuba lutshintsho olumangalisayo. Nangona imeko isenokungafani nemarike yaseTshayina, nceda ujonge ikholamu ethi “iTshayina kunye nabashishina abancinci” ukuze ufumane iinkcukacha ezithe vetshe.
Esinye sezizathu zokuba ii-mini excavators zithandwa kukuba kulula ukunika amandla oomatshini abancinci nabancinci ngombane kunamandla edizili yendabuko. Kwimeko enjalo, ingakumbi kwiindawo zasezidolophini ezikwiimeko zoqoqosho eziphambili, kuhlala kukho imithetho engqongqo malunga nengxolo kunye nokukhutshwa komoya ongcolileyo.
Akukho kunqongophala kwabavelisi be-OEM abaphuhlisa okanye bakhupha ii-mini-excavators zombane-kwasekuqaleni kukaJanuwari 2019, iVolvo Construction Equipment Corporation (iVolvo CE) yabhengeza ukuba phakathi kowama-2020, iza kuqalisa ukuqalisa uthotho lwee-electrical compact excavators (EC15 ukuya kwi-EC27). ) kunye nee-wheel loaders (L20 ukuya kwi-L28), kwaye yamisa uphuhliso olutsha lwale modeli olusekelwe kwiinjini zedizili.
Enye i-OEM efuna umbane kweli candelo lezixhobo yi-JCB, exhotyiswe nge-19C-1E miniature electric excavator yenkampani. I-JCB 19C-1E inikwa amandla ziibhetri ezine ze-lithium-ion, ezinokubonelela nge-20kWh yokugcina amandla. Kubathengi abaninzi be-excavator abancinci, zonke ii-shift zomsebenzi zinokugqitywa ngetshaja enye. I-19C-1E ngokwayo yimodeli enamandla encinci engenazo ii-exhaust emission ngexesha lokusetyenziswa kwaye izolile kakhulu kuneemashini eziqhelekileyo.
Kutshanje i-JCB ithengise iimodeli ezimbini kwisityalo i-J Coffey eLondon. UTim Rayner, uMphathi weMisebenzi kwiSebe leZityalo zeCoffey, uthe: “Inzuzo ephambili kukuba akukho kukhutshwa kwegesi ngexesha lokusetyenziswa. Xa usebenzisa i-19C-1E, abasebenzi bethu abayi kuchaphazeleka kukukhutshwa kwegesi yedizili. Ekubeni izixhobo zokulawula ukukhutshwa kwegesi (ezifana nezixhobo zokukhupha kunye nemibhobho) zingasafuneki, iindawo ezivaliweyo ngoku zicacile kwaye zikhuselekile ukusebenza. Imoto encinci yombane ye-JCB izisa ixabiso kwishishini nakwishishini liphela.”
Enye i-OEM egxile kumbane yiKubota. “Kwiminyaka yakutshanje, ukuthandwa kwee-excavator ezincinci ezisebenzisa amafutha ahlukileyo (afana nombane) kuye kwanda ngokukhawuleza,” utshilo uGlen Hampson, umphathi wophuhliso lweshishini eKubota UK.
"Eyona nto iphambili ekuqhubeni oku zizixhobo zombane ezivumela abaqhubi ukuba basebenze kwiindawo ezimiselweyo ezinokukhupha umoya omninzi. Injini inokwenza umsebenzi wenziwe kwiindawo ezingaphantsi komhlaba ngaphandle kokukhupha umoya oyingozi. Ukuphuma kwengxolo okunciphileyo kuyenza ifaneleke kakhulu ukwakhiwa kwizixeko okanye kwiindawo ezinabantu abaninzi."
Ekuqaleni konyaka, iKubota yaqalisa iprototype encinci yombane eKyoto, eJapan. UHampson wongeze wathi: “EKubota, eyona nto iphambili kuthi iya kuhlala ikukuphuhlisa oomatshini abahlangabezana neemfuno zabathengi - oomatshini bophuhliso lombane baya kusinceda ukuba sikwenze oku.”
Kutshanje iBobcat ibhengeze ukuba iza kuqalisa uthotho olutsha lwee-excavator ezincinci ezinobukhulu obuziitoni ezi-2-4, kuquka uthotho olutsha lwee-excavator ezintlanu ezincinci: i-E26, i-E27z, i-E27, i-E34 kunye ne-E35z. Le nkampani ithi enye yezona zinto zibalaseleyo kolu thotho yingcamango yoyilo lodonga lwesilinda sangaphakathi (CIB).
UMiroslav Konas, uMphathi weeMveliso zeBobcat Excavators eYurophu, eMbindi Mpuma naseAfrika, uthe: “Inkqubo yeCIB yenzelwe ukoyisa ikhonkco elibuthathaka kakhulu kwii-mini-excavators-ii-boom cylinders zingonakalisa olu hlobo lwe-excavator ngokulula. Umzekelo, xa ulayisha inkunkuma kunye nezinto zokwakha ngeelori Oku kubangelwa kukungqubana ecaleni nezinye izithuthi.
"Oku kufezekiswa ngokufaka isilinda ye-hydraulic kwisakhiwo se-boom esandisiweyo, ngaloo ndlela kuthintelwe ukungqubana nomphezulu we-blade kunye necala lesithuthi. Enyanisweni, isakhiwo se-boom sinokukhusela isilinda ye-hydraulic boom kuyo nayiphi na indawo."
Ngenxa yokunqongophala kwabasebenzi abanezakhono kushishino, akukaze kube yinto ebaluleke kangaka ukwenza abo banyamezelayo bonwabe. I-Volvo CE ithi isizukulwana esitsha se-ECR58 F compact excavator esineetoni ezi-6 sinekhabhi enkulu kakhulu kushishino.
Indawo yokusebenza elula kunye namava alula ukuyisebenzisa axhasa impilo, ukuzithemba kunye nokhuseleko lomqhubi. Indawo yesihlalo kwi-joystick itshintshiwe kwaye iphuculwe ngelixa isaxhonywa kunye - I-Volvo Construction Equipment ithe ubuchwepheshe bungeniswe kushishino.
Ikhabhathi yenzelwe ukubonelela ngomgangatho ophezulu wokulula komqhubi, kunye nokuthintela isandi, iindawo ezininzi zokugcina, kunye nee-port ze-12V kunye ne-USB. Iifestile zangaphambili ezivulekileyo ngokupheleleyo kunye neefestile ezisecaleni ezityibilikayo zenza kube lula ukubona yonke indawo, kwaye umqhubi une-flywheel efana nemoto, umboniso wemibala ye-intshi ezintlanu kunye neemenyu ezilula ukuzisebenzisa.
Intuthuzelo yabaqhubi ibaluleke kakhulu, kodwa esinye isizathu sokuthandwa ngokubanzi kwecandelo le-mini excavator kukwanda okuqhubekayo koluhlu lwezixhobo ezibonelelwayo. Umzekelo, i-ECR58 yeVolvo Construction Equipment inezixhobo ezahlukeneyo ezilula ukuzitshintsha, kuquka iibhakethi, ii-breakers, ii-thumbs, kunye nee-intendred quick couplings ezintsha.
Xa ethetha ngokuthandwa kwee-emba ezincinci, umlawuli ophetheyo we-Off-Highways Research uChris Sleight ugxininise ezi zinto ziqhotyoshelweyo. Uthe: “Kwicala elilula, uluhlu lwezixhobo ezikhoyo lubanzi, oko kuthetha ukuba [ii-emba ezincinci] zihlala zithandwa kakhulu zizixhobo ze-Pneumatic kunezisebenzi zezandla. Oku kungenxa yokuba kunceda ukunciphisa impembelelo yengxolo kunye nokungcangcazela kubasebenzi, kwaye kuba kunokushukumisa abasebenzi kude nezixhobo.”
I-JCB yenye yeenkampani ezininzi ze-OEM ezifuna ukubonelela abathengi ngeendlela zombane zee-mini excavators
USlater wongeze wathi: “EYurophu naseMntla Melika, oomashini abancinci bokugrumba batshintsha ezinye iintlobo zezixhobo. Kwinqanaba eliphezulu lesikali, indawo yayo encinci kunye nomthamo wayo wokuslewulela ngama-360-degree kuthetha ukuba ngoku ngokubanzi ingcono kunomthwalo we-backhoe. Lo matshini uthandwa kakhulu.”
UKonas kaBobcat uvumile ngokubaluleka kwezincamathiselo. Uthe: “Iintlobo ezahlukeneyo zeebhakethi esizibonelelayo zisesezona “zixhobo” ziphambili kuthotho lwee-attachment ezingama-25 ezahlukeneyo esizibonelela ngee-mini excavators, kodwa ngefosholo ephucukileyo Ngophuhliso lweebhakethi, le ndlela iyakhula. Izixhobo ze-hydraulic ziya zithandwa ngakumbi. Yiyo loo nto siphuhlise inkqubo ye-A-SAC, esetyenziswa ngeesekethe ezincedisayo ezizimeleyo ezihlanu kumatshini. Sikholelwa ukuba iBobcat iya kuba lolona phawu luphambili kwimarike lokusebenzisa izixhobo ezintsonkothileyo.
"Ukudibanisa imigca yokuncedisa ye-hydraulic efakwe engalweni kunye netekhnoloji ye-A-SAC ekhethiweyo kunokubonelela ngeendlela ezahlukeneyo zokwenza ngokwezifiso zomatshini ukuhlangabezana nazo naziphi na iimfuno zezixhobo, ngaloo ndlela kuphucula ngakumbi indima yaba bembi njengabanini bezixhobo ababalaseleyo."
I-Hitachi Construction Machinery (Europe) ikhuphe iphepha elimhlophe malunga nekamva lecandelo lezixhobo ezincinci zaseYurophu. Babonise ukuba ama-70% ee-mini excavators ezithengiswa eYurophu zinobunzima obungaphantsi kweetoni ezi-3. Oku kungenxa yokuba ukufumana imvume kunokutsala ngokulula enye yeemodeli kwitreyila enelayisenisi yokuqhuba eqhelekileyo.
Eli phepha limhlophe liqikelela ukuba ukujonga kude kuya kudlala indima ebaluleke ngakumbi kwimarike yezixhobo zokwakha ezincinci, kwaye ii-mini excavators ziyinxalenye ebalulekileyo yayo. Ingxelo yathi: “Ukulandelela indawo yezixhobo ezincinci kubaluleke kakhulu kuba zihlala zifuduselwa kwenye indawo yomsebenzi ziye kwenye.
Ngoko ke, idatha yendawo kunye neeyure zokusebenza inokunceda abanini, ingakumbi iinkampani eziqeshisayo, bacwangcise, baphucule ukusebenza kakuhle kwaye bacwangcise umsebenzi wokulungisa. Ngokwembono yokhuseleko, ulwazi oluchanekileyo lwendawo nalo lubalulekile - kulula kakhulu ukuba oomatshini abancinci kunokugcina abakhulu, ngoko ke ukubiwa kwezixhobo ezincinci kuxhaphake kakhulu.
