Zipangizo zofukula zazing'ono ndi chimodzi mwa zipangizo zomwe zikukula mofulumira kwambiri, ndipo kutchuka kwawo kukuoneka kuti kukupitirirabe kukula. Malinga ndi deta ya Off-Highway Research, malonda apadziko lonse a zofukula zazing'ono adafika pamlingo wapamwamba kwambiri chaka chatha, kupitirira mayunitsi 300,000.
Mwachikhalidwe, misika yayikulu ya opanga zinthu zazing'ono yakhala mayiko otukuka, monga Japan ndi Western Europe, koma kutchuka kwawo m'maiko ambiri omwe akutukuka kwawonjezeka m'zaka khumi zapitazi. Yodziwika kwambiri mwa izi ndi China, yomwe pakadali pano ndi msika waukulu kwambiri padziko lonse lapansi wa opanga zinthu zazing'ono.
Poganizira kuti ofukula zinthu zazing'ono amatha kusintha ntchito zamanja, palibe kusowa kwa antchito m'maiko okhala ndi anthu ambiri padziko lonse lapansi. Izi zitha kukhala kusintha kodabwitsa. Ngakhale kuti zinthu sizingakhale ngati msika waku China, chonde onani gawo la "China ndi ofukula zinthu ang'onoang'ono" kuti mudziwe zambiri.
Chimodzi mwa zifukwa zomwe ma mini-excavator amatchuka ndichakuti n'kosavuta kupatsa mphamvu makina ang'onoang'ono komanso ang'onoang'ono okhala ndi magetsi kuposa mphamvu ya dizilo yachikhalidwe. Pankhaniyi, makamaka m'mizinda yachuma chotukuka, nthawi zambiri pamakhala malamulo okhwima okhudza phokoso ndi utsi woipa.
Palibe kusowa kwa opanga opanga ma OEM omwe akupanga kapena kutulutsa ma mini-excavator amagetsi - kuyambira Januwale 2019, Volvo Construction Equipment Corporation (Volvo CE) idalengeza kuti pofika pakati pa 2020, iyamba kuyambitsa ma multi-compact electric excavator (EC15 mpaka EC27). Ndi ma wheel loaders (L20 mpaka L28), ndipo yaletsa kupanga kwatsopano kwa mitundu iyi kutengera injini za dizilo.
Kampani ina ya OEM yomwe ikufuna magetsi m'gawo la zida izi ndi JCB, yomwe ili ndi chofukula chamagetsi cha 19C-1E cha kampaniyo. JCB 19C-1E imayendetsedwa ndi mabatire anayi a lithiamu-ion, omwe amatha kupereka mphamvu yosungira 20kWh. Kwa makasitomala ambiri ang'onoang'ono ofukula, ntchito zonse zitha kumalizidwa ndi chaji imodzi. 19C-1E yokha ndi chitsanzo champhamvu chocheperako chomwe sichimatulutsa utsi wochuluka panthawi yogwiritsa ntchito ndipo chimakhala chete kwambiri kuposa makina wamba.
Posachedwapa JCB yagulitsa mitundu iwiri ku fakitale ya J Coffey ku London. Tim Rayner, Woyang'anira Ntchito ku Dipatimenti ya Zomera za Coffey, anati: “Phindu lalikulu ndilakuti palibe mpweya woipa womwe umatuluka panthawi yogwiritsa ntchito. Pogwiritsa ntchito 19C-1E, antchito athu sadzakhudzidwa ndi mpweya woipa wa dizilo. Popeza zida zowongolera mpweya woipa (monga zida zochotsera ndi mapaipi) sizikufunikanso, malo otsekedwa tsopano ndi omveka bwino komanso otetezeka kugwira ntchito. Galimoto yaying'ono yamagetsi ya JCB imabweretsa phindu ku bizinesi ndi makampani onse.”
Kampani ina ya OEM yomwe imayang'ana kwambiri pa magetsi ndi Kubota. "M'zaka zaposachedwapa, kutchuka kwa makina ofukula ang'onoang'ono omwe amagwiritsa ntchito mafuta ena (monga magetsi) kwawonjezeka mofulumira," adatero Glen Hampson, manejala wa chitukuko cha bizinesi ku Kubota UK.
"Chinthu chachikulu chomwe chimapangitsa izi ndi zida zamagetsi zomwe zimathandiza ogwiritsa ntchito kugwira ntchito m'malo omwe mpweya umatulutsa mpweya wochepa. Injiniyo ingathandizenso kuti ntchito ichitike m'malo obisika pansi pa nthaka popanda kutulutsa mpweya woipa. Kuchepa kwa phokoso kumapangitsanso kuti ikhale yoyenera kumanga m'mizinda kapena m'malo okhala anthu ambiri."
Kumayambiriro kwa chaka, Kubota adayambitsa chipangizo chaching'ono chopangira magetsi ku Kyoto, Japan. Hampson adawonjezera kuti: "Ku Kubota, cholinga chathu nthawi zonse chidzakhala kupanga makina omwe amakwaniritsa zosowa za makasitomala - makina opangira magetsi adzatithandiza kuti izi zitheke."
Posachedwapa Bobcat yalengeza kuti iyambitsa makina atsopano ofukula ang'onoang'ono a 2-4 ton R, kuphatikizapo makina atsopano ofukula asanu: E26, E27z, E27, E34 ndi E35z. Kampaniyo ikunena kuti chimodzi mwa zinthu zabwino kwambiri pa makinawa ndi kapangidwe ka khoma lamkati la silinda (CIB).
Miroslav Konas, Woyang'anira Zogulitsa za Bobcat Excavators ku Europe, Middle East ndi Africa, anati: "Dongosolo la CIB lapangidwa kuti ligonjetse ulalo wofooka kwambiri wa mini-excavators-ma boom cylinders amatha kuwononga mosavuta mtundu uwu wa excavator. Mwachitsanzo, poyika zinyalala ndi zipangizo zomangira ndi magalimoto akuluakulu. Izi zimachitika chifukwa cha kugundana kwa mbali ndi magalimoto ena.
"Izi zimachitika poika silinda ya hydraulic mu kapangidwe ka boom yotambasuka, potero kupewa kugundana ndi pamwamba pa tsamba ndi mbali ya galimotoyo. Ndipotu, kapangidwe ka boom kamatha kuteteza silinda ya boom ya hydraulic pamalo aliwonse."
Chifukwa cha kusowa kwa akatswiri odziwa bwino ntchito m'makampani, sikunakhalepo kofunika kwambiri kupangitsa anthu opirira kukhala osangalala. Volvo CE ikunena kuti mbadwo watsopano wa chotsukira cha ECR58 F cha matani 6 uli ndi taxi yayikulu kwambiri m'makampaniwa.
Malo ogwirira ntchito osavuta komanso zomwe zingagwiritsidwe ntchito mosavuta zimathandiza thanzi, kudzidalira komanso chitetezo cha wogwiritsa ntchito. Malo a mpando ku joystick asinthidwa ndikuwongoleredwa pomwe akuyimitsidwa pamodzi - Volvo Construction Equipment yati ukadaulowu walowetsedwa mumakampani opanga magalimoto.
Kabatiyi yapangidwa kuti ipereke mphamvu yapamwamba kwambiri kwa woyendetsa, yokhala ndi chotetezera mawu, malo ambiri osungiramo zinthu, ndi ma 12V ndi ma USB ports. Mawindo akutsogolo otseguka bwino ndi mawindo akumbali otsetsereka zimathandiza kuwona bwino, ndipo woyendetsayo ali ndi flywheel yofanana ndi galimoto, chiwonetsero chamitundu ya mainchesi asanu komanso menyu osavuta kugwiritsa ntchito.
Chitonthozo cha ogwiritsa ntchito n'chofunika kwambiri, koma chifukwa china chomwe chapangitsa kuti gawo la mini excavator lifalikire kwambiri ndi kukula kosalekeza kwa mitundu yosiyanasiyana ya zowonjezera zomwe zimaperekedwa. Mwachitsanzo, Volvo Construction Equipment's ECR58 ili ndi mitundu yosiyanasiyana ya zowonjezera zosavuta kusintha, kuphatikizapo mabaketi, ma breaker, ma thumbs, ndi ma coupling atsopano ofulumira.
Polankhula za kutchuka kwa makina ofukula ang'onoang'ono, mkulu wa Off-Highways Research, Chris Sleight, adagogomezera zomangirazo. Iye anati: "Ponena za kupepuka, mitundu yosiyanasiyana ya zowonjezera zomwe zilipo ndi yotakata, zomwe zikutanthauza kuti [makina ofukula ang'onoang'ono] nthawi zambiri zida za Pneumatic ndizodziwika kwambiri kuposa ogwira ntchito pamanja. Izi zili choncho chifukwa zimathandiza kuchepetsa phokoso ndi kugwedezeka kwa ogwira ntchito, komanso chifukwa zimatha kusuntha antchito kutali ndi zidazo."
JCB ndi imodzi mwa makampani ambiri opanga zinthu zakale omwe akufuna kupatsa makasitomala njira zamagetsi zogwiritsira ntchito makina ofukula zinthu ang'onoang'ono
Slater anawonjezeranso kuti: "Ku Ulaya komanso ku North America, makina ofukula ang'onoang'ono akulowa m'malo mwa zipangizo zina. Pamwamba kwambiri pa sikeloyi, malo ake ochepa komanso mphamvu yake yodulira ndi madigiri 360 zikutanthauza kuti tsopano nthawi zambiri imakhala yabwino kuposa kunyamula zinthu kuchokera ku backhoe. Makinawa ndi otchuka kwambiri."
Konas wa Bobcat adagwirizana ndi kufunika kwa zomangira. Iye anati: “Mitundu yosiyanasiyana ya zidebe zomwe timapereka ikadali “zida” zazikulu mu mndandanda 25 wolumikizira womwe timapereka kwa ma mini-excavator, koma ndi fosholo yapamwamba kwambiri. Ndi chitukuko cha zidebe, izi zikupita patsogolo. Zowonjezera za hydraulic zikutchuka kwambiri. Ichi ndichifukwa chake tidapanga dongosolo la A-SAC, lomwe limagwiritsidwa ntchito ndi ma circuits odziyimira pawokha asanu pamakina. Tikukhulupirira kuti Bobcat idzakhala mtundu wapamwamba kwambiri pamsika wogwiritsa ntchito zowonjezera zovuta zotere.
"Kuphatikiza mizere yothandizira ya hydraulic yokhala ndi dzanja ndi ukadaulo wa A-SAC wosankha kungapereke njira zosiyanasiyana zosintha makina kuti zikwaniritse zofunikira zilizonse zowonjezera, motero kupititsa patsogolo ntchito ya ofukula awa ngati osungira zida abwino kwambiri."
Kampani ya Hitachi Construction Machinery (Europe) yatulutsa chikalata choyera chokhudza tsogolo la gawo la zida zazing'ono ku Europe. Iwo anena kuti 70% ya ma mini-evacuator omwe amagulitsidwa ku Europe amalemera zosakwana matani atatu. Izi zili choncho chifukwa kupeza chilolezo kumatha kukoka mosavuta imodzi mwa mitunduyi pa thireyila yokhala ndi chilolezo choyendetsa galimoto nthawi zonse.
Pepala loyera likuneneratu kuti kuyang'anira patali kudzagwira ntchito yofunika kwambiri pamsika wa zida zomangira zazing'ono, ndipo ma mini-embarching ndi gawo lofunika kwambiri. Lipotilo linati: "Kutsatira komwe kuli zida zazing'ono ndikofunikira kwambiri chifukwa nthawi zambiri zimasamutsidwa kuchokera pamalo ena kupita kwina."
Chifukwa chake, deta ya malo ndi maola ogwirira ntchito ingathandize eni ake, makamaka makampani obwereketsa, kukonzekera, kukonza magwiridwe antchito ndi kukonza nthawi yogwirira ntchito. Malinga ndi chitetezo, chidziwitso cholondola cha malo nachonso n'chofunikira - n'kosavuta kuba makina ang'onoang'ono kuposa kusunga akuluakulu, kotero kuba zida zazing'ono kumakhala kofala kwambiri.
Opanga osiyanasiyana amagwiritsa ntchito ma excavator awo ang'onoang'ono kuti apereke zida zosiyanasiyana za telematics. Palibe muyezo wamakampani. Ma excavator ang'onoang'ono a Hitachi alumikizidwa ku njira yawo yowunikira kutali Global e-Service, ndipo deta ingapezekenso kudzera pa mafoni a m'manja.
Ngakhale malo ndi maola ogwirira ntchito ndizofunikira kwambiri pa chidziwitso, lipotilo likuganiza kuti eni zida za m'badwo wotsatira adzafuna kuwona zambiri mwatsatanetsatane. Mwiniwakeyo akuyembekeza kupeza zambiri kuchokera kwa wopanga. Chimodzi mwa zifukwa zake ndi kuchuluka kwa makasitomala achichepere komanso odziwa bwino zaukadaulo omwe amatha kumvetsetsa bwino ndikusanthula zambiri kuti akonze zokolola ndi magwiridwe antchito.
Posachedwapa Takeuchi yatulutsa chimbale cha hydraulic cha TB257FR, chomwe chalowa m'malo mwa TB153FR. Chimbale chatsopanochi chatsegula
Kuthamanga kwa mbali yakumanzere kuchokera kumanja pamodzi ndi kugwedezeka kwa mchira kolimba kumalola kuti izungulire mokwanira popanda kugwedezeka kwambiri.
Kulemera kwa ntchito ya TB257FR ndi 5840 kg (matani 5.84), kuya kwa kukumba ndi 3.89m, mtunda wokulirapo kwambiri ndi 6.2m, ndipo mphamvu yokumba ndowa ndi 36.6kN.
