Abavubukuli abancane bangenye yezinhlobo zemishini ezikhula ngokushesha, futhi ukuthandwa kwabo kubonakala kuqhubeka kwanda. Ngokusho kwedatha evela ku-Off-Highway Research, ukuthengiswa komhlaba wonke kwemigodi emincane kufinyelele endaweni ephakeme kakhulu ngonyaka odlule, okudlula amayunithi angama-300,000.
Ngokwesiko, izimakethe eziyinhloko zama-micro-excavators kube amazwe athuthukile, njengeJapane neNtshonalanga Yurophu, kodwa ukuthandwa kwawo emazweni amaningi athuthukile kwezomnotho kuye kwanda kule minyaka eyishumi edlule. Edume kakhulu kulawa yiShayina, okuyimakethe yama-mini excavator enkulu kunazo zonke emhlabeni.
Uma kubhekwa ukuthi ama-mini-cavators angakwazi ukufaka esikhundleni somsebenzi wezandla, akukho ukushoda kwezisebenzi emazweni anabantu abaningi kakhulu emhlabeni. Lokhu kungase kube ushintsho olumangalisayo. Nakuba isimo singase singafani nemakethe yaseShayina, sicela uhlole ikholomu ethi “I-China nama-excavators amancane” ukuze uthole imininingwane eyengeziwe.
Esinye sezizathu zokuthi kungani ama-mini excavators athandwa ukuthi kulula ukufaka amandla emishini emincane futhi ehlangene kakhulu ngogesi kunamandla wendabuko kadizili. Kulokhu, ikakhulukazi ezindaweni zasemadolobheni ezinomnotho othuthukile, kuvame ukuba nemithetho eqinile emayelana nomsindo nokukhipha umoya.
Akukho ukushoda kwabakhiqizi be-OEM abakha noma abadedela ama-excavators amancane kagesi-kusukela ngoJanuwari 2019, I-Volvo Construction Equipment Corporation (i-Volvo CE) imemezele ukuthi maphakathi no-2020, izoqala ukwethula uchungechunge lwezimbambi ezihlangene zikagesi (EC15 kuya ku-EC27). ) Futhi izilayishi zamasondo (L20 kuya ku-L28), futhi zamisa ukuthuthukiswa okusha kwalezi zinhlobo ezisekelwe ezinjini zikadizili.
Enye i-OEM efuna amandla kulo mkhakha wemishini yi-JCB, efakwe i-19C-1E miniature electric excavator yenkampani. I-JCB 19C-1E inikwa amandla amabhethri e-lithium-ion amane, anganikeza u-20kWh wokugcina amandla. Kumakhasimende amaningi ama-excavator amancane, wonke amashifu okusebenza angaqedwa ngenkokhiso eyodwa. I-19C-1E ngokwayo iyimodeli enamandla ehlangene ekhipha umoya oyiziro ngesikhathi sokusetshenziswa futhi ithule kakhulu kunemishini evamile.
I-JCB isanda kuthengisa izinhlobo ezimbili embonini ye-J Coffey eLondon. U-Tim Rayner, Umphathi Wokusebenza eMnyangweni Wezitshalo Zekhofi, uphawule wathi: “Inzuzo enkulu ukuthi akukho okuphumayo ngesikhathi sokusetshenziswa. Uma sisebenzisa i-19C-1E, abasebenzi bethu ngeke bathinteke ekukhishweni kukadizili. Njengoba imishini yokulawula ukungcola (njengamadivaysi okukhipha kanye namapayipi) ingasadingeki, izindawo ezivalekile manje sezicacile futhi ziphephile ukusebenza.
Enye i-OEM egxile kugesi iKubota. "Eminyakeni yamuva nje, ukuthandwa kwabavubukuli abancane abasebenzisa amafutha ahlukile (njengakagesi) kuye kwanda ngokushesha," kusho uGlen Hampson, umphathi wezokuthuthukiswa kwebhizinisi e-Kubota UK.
"Isisusa esiyinhloko salokhu izinto zikagesi ezivumela abaqhubi ukuthi basebenze ezindaweni ezinqunyelwe umoya omncane. Injini ingakwazi futhi ukunika amandla umsebenzi ukuba wenziwe ezindaweni ezivalekile ngaphandle kokukhipha igesi eyingozi. Ukukhishwa komsindo oncishisiwe nakho kwenza kube kakhulu. Ifaneleka ukwakhiwa emadolobheni noma ezindaweni ezinabantu abaningi."
Ekuqaleni konyaka, u-Kubota wethula i-compact miniature electric excavator prototype e-Kyoto, e-Japan. U-Hampson wengeze wathi: “E-Kubota, into eza kuqala kithi kuyohlale kuwukuthuthukisa imishini ehlangabezana nezidingo zamakhasimende—imishini yokuthuthukisa ugesi izosenza sikwazi Ukukwenza kwenzeke.”
UBobcat usanda kumemezela ukuthi uzokwethula uchungechunge olusha lwe-2-4 ton R lwezimbambi ezincane, okuhlanganisa uchungechunge olusha lwezimbambi ezinhlanu ezihlangene: E26, E27z, E27, E34 kanye ne-E35z. Le nkampani ithi esinye sezici ezivelele zalolu chungechunge umqondo wokuklama wodonga lwangaphakathi lwesilinda (CIB).
UMiroslav Konas, oyiMenenja yoMkhiqizo weBobcat Excavators eYurophu, eMpumalanga Ephakathi nase-Afrika, uthe: “Uhlelo lwe-CIB lwenzelwe ukunqoba isixhumanisi esintekenteke kunazo zonke kuma-mini-excavators-ama-boom cylinders angalulimaza kalula lolu hlobo lwe-excavator.Isibonelo, lapho ulayisha imfucumfucu kanye nezinto zokwakha ngamaloliKubangelwa ukushayisana eceleni nezinye izimoto.
"Lokhu kufezwa ngokufaka isilinda esisebenza ngogesi esakhiweni esinwetshiwe se-boom, ngaleyo ndlela sigweme ukungqubuzana nendawo engaphezulu yensingo kanye nohlangothi lwemoto. Eqinisweni, ukwakheka kwe-boom kungavikela isilinda esisebenza nge-hydraulic boom kunoma yisiphi isimo."
Ngenxa yokuntuleka kwabasebenzi abanamakhono embonini, akukaze kubaluleke kakhulu ukujabulisa labo abaphikelelayo. I-Volvo CE ithi isizukulwane esisha se-6-ton ECR58 F compact excavator sinekhebhu ebanzi kakhulu embonini.
Indawo yokusebenza eyenziwe lula nolwazi olusebenziseka kalula lusekela impilo, ukuzethemba nokuphepha komsebenzisi. Isikhundla sesihlalo ku-joystick sishintshile futhi sathuthukiswa ngenkathi sisamisiwe ndawonye-I-Volvo Construction Equipment ithe ubuchwepheshe sebungenisiwe embonini.
Ikhebhu yakhelwe ukuhlinzeka ngezinga eliphezulu kakhulu lokusebenziseka kalula, ngokufaka umsindo, izindawo eziningi zokugcina, kanye namachweba angu-12V kanye ne-USB. Amafasitela angaphambili avuleke ngokugcwele namawindi asemaceleni ashelelayo enza kube lula ukubona yonke indawo, futhi osebenzisa i-flywheel unesitayela semoto, isibonisi sombala esingamayintshi amahlanu kanye namamenyu okulula ukuwahlola.
Ukunethezeka kwe-opharetha kubaluleke ngempela, kodwa esinye isizathu sokuthandwa kabanzi kwengxenye ye-mini excavator ukwanda okuqhubekayo kohlu lwezesekeli ezinikeziwe. Isibonelo, i-Volvo Construction Equipment's ECR58 inezinhlobonhlobo zezinsiza okulula ukuzishintsha, okuhlanganisa amabhakede, ama-breaker, izithupha, nama-coupling asheshayo athambekele amasha.
Lapho ekhuluma ngokuduma kwemigodi emincane, umqondisi ophethe we-Off-Highways Research uChris Sleight ugcizelele okunamathiselwe. Wathi: “Emaphethelweni alula, izinhlobonhlobo zezisekeli ezitholakalayo zibanzi, okusho ukuthi [abavubukuli abancane] ngokuvamile amathuluzi omoya athandwa kakhulu kunezisebenzi zezandla.
I-JCB ingenye yama-OEM amaningi afuna ukuhlinzeka amakhasimende ngezinketho zikagesi zokumba ama-mini
USlater wanezela futhi: “EYurophu ngisho naseNyakatho Melika, izimbiwa ezincane zithatha indawo yezinye izinhlobo zemishini.Ekugcineni okuphezulu kwesikali, indawo yayo encane yonyawo kanye nomthamo wokusla wama-degree angu-360 kusho ukuthi ngokuvamile manje isingcono kakhulu kunokulayisha i-backhoe. Lo mshini uthandwa kakhulu.”
I-Konas kaBobcat ivumelane nokubaluleka kokunamathiselwe. Uthe: "Izinhlobo ezahlukene zamabhakede esizihlinzekayo ziseyizo "amathuluzi" ayinhloko ochungechungeni lokunamathiselwe oluhlukene lwama-25 esiwahlinzeka ngama-excavators amancane, kodwa ngefosholo elithuthuke kakhulu Ngokuthuthukiswa kwamabhakede, lo mkhuba uthuthuka. Izesekeli ze-hydraulic ziya ngokuya zithandwa. Yingakho sithuthukise uhlelo lwe-A-SAC, olusetshenziswa nezinkampani ezizimele ezifika ezinhlanu emshinini we-Bobe esikholelwa ukuthi zizoba usizo oluthuthukisiwe kakhulu. emakethe ukusebenzisa izesekeli eziyinkimbinkimbi.
"Ukuhlanganisa imigqa yokusiza ye-hydraulic egxunyekwe ingalo nobuchwepheshe be-A-SAC obungakhethwa kungahlinzeka ngezinketho eziningi zokwenza ngokwezifiso umshini ukuhlangabezana nanoma yiziphi izidingo zokufinyelela, ngaleyo ndlela kuthuthukiswe indima yalaba bamba njengabaphathi bamathuluzi abahle kakhulu."
I-Hitachi Construction Machinery (i-Europe) ikhiphe iphepha elimhlophe ngekusasa lomkhakha we-European compact equipment. Baveze ukuthi u-70% wama-mini excavator adayiswa e-Europe anesisindo esingaphansi kwamathani amathathu. Lokhu kungenxa yokuthi ukuthola imvume kungakwazi ukudonsa kalula enye yamamodeli kwi-trailer enelayisensi yokushayela evamile.
Iphepha elimhlophe libikezela ukuthi ukuqapha okukude kuzodlala indima ebaluleke kakhulu emakethe yemishini yokwakha ehlangene, futhi ama-mini excavators ayingxenye ebalulekile yakho. Lo mbiko wathi: “Ukulandelela indawo yemishini emincane kubaluleke kakhulu ngoba ngokuvamile isuke isuswe kwenye indawo iyiswe kwenye.
Ngakho-ke, idatha yendawo namahora okusebenza ingasiza abanikazi, ikakhulukazi izinkampani eziqashisayo, bahlele, bathuthukise ukusebenza kahle futhi bahlele umsebenzi wokulungisa. Ngokombono wezokuphepha, ulwazi olunembile lwendawo nalo lubalulekile-kulula kakhulu ukweba imishini emincane kunokugcina emikhulu, ngakho ukuntshontshwa kwamadivayisi ahlangene kuvame kakhulu. ”
Abakhiqizi abahlukene basebenzisa ama-excavators abo amancane ukuze banikeze izinsiza ezihlukahlukene ze-telematics. Alikho izinga lemboni. Ama-excavators amancane e-Hitachi axhunywe ohlelweni lwayo lokuqapha olukude I-Global e-Service, futhi idatha ingafinyelelwa ngama-smartphone.
Nakuba indawo namahora okusebenza kuwukhiye olwazini, umbiko uqagela ukuthi abanikazi bemishini yesizukulwane esilandelayo bazofuna ukubuka idatha enemininingwane eyengeziwe. Umnikazi unethemba lokuthola idatha eyengeziwe kumkhiqizi. Esinye sezizathu ukuthutheleka kwamakhasimende asemancane, ane-tech-savvy angakwazi ukuqonda kangcono futhi ahlaziye idatha ukuze athuthukise ukukhiqiza nokusebenza kahle. ”
U-Takeuchi usanda kwethula i-TB257FR compact hydraulic excavator, elandela i-TB153FR. I-excavator entsha ine
I-boom yesokunxele yesokunxele ehlanganiswe nokushwibeka komsila okuqinile kuyivumela ukuthi ijikelezise ngokugcwele ngokugqitshwa kancane.
Isisindo sokusebenza se-TB257FR singama-5840 kg (amathani angu-5.84), ukujula kokumba kungu-3.89m, ibanga elikhulu lokunwetshwa liyi-6.2m, futhi amandla okumba ibhakede angu-36.6kN.
Umsebenzi we-boom wesokunxele nesokudla uvumela i-TB257FR ukuthi imbe i-offset kwesokunxele nakwesokudla ngaphandle kokubeka kabusha umshini. Ngaphezu kwalokho, lesi sici sigcina ama-counterweights amaningi aqondaniswe nesikhungo somshini, ngaleyo ndlela sithuthukisa ukuzinza.
Kuthiwa enye inzuzo yalolu hlelo yikhono le-boom ukuthi libekwe ngaphezu kwesikhungo, okwenza kube lula ukwenza ukujikeleza okuphelele ngaphakathi kobubanzi bethrekhi. Lokhu kuyenza ilungele ukusebenza ezindaweni ezihlukene zokwakha ezivalekile, okuhlanganisa amaphrojekthi emigwaqo namabhuloho, imigwaqo yedolobha naphakathi kwezakhiwo.
"I-Takeuchi iyakujabulela ukuhlinzeka nge-TB257FR kumakhasimende ethu," kusho u-Toshiya Takeuchi, uMongameli we-Takeuchi. "Ukuzibophezela kuka-Takeuchi kusiko lethu lokusungula izinto ezintsha kanye nobuchwepheshe obuthuthukisiwe kubonakala kulo mshini. I-boom ye-offset yesokunxele nesokudla ivumela ukuguquguquka okukhulu komsebenzi, futhi indawo ephansi yamandla adonsela phansi kanye nokubekwa okuthuthukisiwe kwe-counterweight kudala inkundla ezinze ngokwedlulele. Umthamo omkhulu ufana nemishini evamile.
U-Shi Jang we-Off-Highway Research ukhiphe isexwayiso esiqaphile emakethe yaseShayina kanye nezimbiwa ezincane, exwayisa ngokuthi imakethe ingase igcwale. Lokhu kungenxa yokuthi amanye ama-OEM aseShayina afuna ukukhulisa ngokushesha isabelo sawo semakethe ehlise intengo yezimba zabo ezincane cishe ngo-20%. Ngakho-ke, njengoba ukuthengisa kukhula, imingcele yenzuzo iyancishiswa, futhi manje sekunemishini eminingi emakethe kunanini ngaphambili.
Intengo yokuthengisa yabavubukuli abancane yehle okungenani ngo-20% uma kuqhathaniswa nonyaka odlule, futhi isabelo semakethe sabakhiqizi bamazwe ngamazwe sehlile ngenxa yokuthi abakwazi ukwehlisa amanani kakhulu ngenxa yemiklamo yabo yemishini ephezulu. Bahlela ukwethula imishini eshibhile esikhathini esizayo, kodwa manje imakethe isigcwele imishini ebiza kancane. “U-Shi Zhang ukhombe.
Amanani aphansi ahehe amakhasimende amaningi amasha ukuthi athenge imishini, kodwa uma kunemishini eminingi kakhulu emakethe futhi umsebenzi unganele, imakethe izokwehla. Naphezu kokuthengisa okuhle, inzuzo yabakhiqizi abahamba phambili iye yacindezelwa ngenxa yamanani aphansi. ”
U-Jang wengeze ngokuthi izintengo eziphansi zenza kube nzima kubathengisi ukwenza inzuzo, futhi ukwehlisa izintengo ukuze kuthuthukiswe ukuthengisa kungase kube nomthelela omubi ekuthengisweni kwesikhathi esizayo.
