ʻO nā mea ʻeli liʻiliʻi kekahi o nā ʻano lako e ulu wikiwiki loa ana, a ke hoʻomau nei ko lākou kaulana i ka piʻi ʻana. Wahi a ka ʻikepili mai Off-Highway Research, ua hōʻea ke kūʻai aku honua o nā mea ʻeli liʻiliʻi i kahi kiʻekiʻe loa i ka makahiki i hala, ma mua o 300,000 mau ʻāpana.
ʻO ka mea maʻamau, ʻo nā mākeke nui no nā micro-excavators ʻo ia nā ʻāina i hoʻomohala ʻia, e like me Iapana a me ʻEulopa Komohana, akā ua piʻi ko lākou kaulana i nā ʻoihana waiwai e kū mai ana i nā makahiki he ʻumi i hala. ʻO Kina ka mea kaulana loa o kēia mau mea, ʻo ia ka mākeke mini excavator nui loa o ka honua i kēia manawa.
Ke noʻonoʻo nei hiki i nā mini-excavator ke pani i ka hana lima, ʻaʻohe hemahema o nā limahana ma nā ʻāina i nui loa ka heluna kanaka o ka honua. He loli kupanaha paha kēia. ʻOiai ʻaʻole like ke kūlana me ka mākeke Kina, e ʻoluʻolu e nānā i ke kolamu "Kina a me nā mea ʻeli liʻiliʻi" no nā kikoʻī hou aku.
ʻO kekahi o nā kumu i kaulana ai nā mini excavators, ʻo ia ka maʻalahi o ka hoʻohana ʻana i ka uila ma mua o ka mana diesel kuʻuna. I kēia hihia, ʻoi aku hoʻi ma nā kikowaena kūlanakauhale o nā ʻoihana holomua, aia nā lula paʻa ma ka walaʻau a me nā hoʻokuʻu ʻana.
ʻAʻohe hemahema o nā mea hana OEM e hoʻomohala nei a hoʻokuʻu paha i nā mīkini ʻeli uila mini - i Ianuali 2019, ua hoʻolaha ʻo Volvo Construction Equipment Corporation (Volvo CE) ma waena o 2020, e hoʻomaka ia e hoʻolauna i kahi moʻo o nā mīkini ʻeli uila compact (EC15 a EC27). ) A me nā mea hoʻouka huila (L20 a L28), a ua hoʻōki i ka hoʻomohala hou ʻana o kēia mau hiʻohiʻona e pili ana i nā mīkini diesel.
ʻO kekahi OEM e ʻimi nei i ka mana ma kēia kahua lako ʻo JCB, i lako me ka mīkini ʻeli uila liʻiliʻi 19C-1E o ka hui. Hoʻohana ʻia ʻo JCB 19C-1E e ʻehā mau pila lithium-ion, hiki ke hāʻawi i ka 20kWh o ka mālama ikehu. No ka hapa nui o nā mea kūʻai aku ʻeli liʻiliʻi, hiki ke hoʻopau ʻia nā hana āpau me ka hoʻouka hoʻokahi. ʻO ka 19C-1E ponoʻī he kumu hoʻohālike liʻiliʻi ikaika me ka ʻole o nā hoʻokuʻu ʻana i ka wā e hoʻohana ai a ʻoi aku ka mālie ma mua o nā mīkini maʻamau.
Ua kūʻai aku nei ʻo JCB i ʻelua mau hiʻohiʻona i ka hale hana ʻo J Coffey ma Ladana. Ua ʻōlelo ʻo Tim Rayner, Luna Hoʻokele Hana o ka ʻOihana Hale Hana ʻo Coffey: "ʻO ka pōmaikaʻi nui, ʻaʻohe hoʻokuʻu ʻana i ka wā e hoʻohana ai. I ka wā e hoʻohana ai i ka 19C-1E, ʻaʻole e hoʻopilikia ʻia kā mākou poʻe limahana e nā hoʻokuʻu diesel. ʻOiai ʻaʻole pono hou nā lako hoʻomalu hoʻokuʻu (e like me nā mea hana unuhi a me nā paipu), ua ʻoi aku ka maʻalahi a me ka palekana o nā wahi i hoʻopaʻa ʻia e hana. Lawe mai ka kaʻa mini uila JCB i ka waiwai i ka ʻoihana a me ka ʻoihana holoʻokoʻa."
ʻO kekahi OEM e kālele ana i ka uila ʻo Kubota. "I nā makahiki i hala iho nei, ua piʻi koke ka kaulana o nā mīkini ʻeli liʻiliʻi i hoʻohana ʻia e nā wahie ʻē aʻe (e like me ka uila)," wahi a Glen Hampson, ka luna hoʻomohala ʻoihana ma Kubota UK.
"ʻO ka mea hoʻokele nui ma hope o kēia, ʻo ia nā lako uila e hiki ai i nā mea hoʻohana ke hana ma nā wahi i kuhikuhi ʻia me ka haʻahaʻa o ka hoʻokuʻu ʻana. Hiki i ka motika ke hiki ke hana i nā hana ma nā wahi paʻa ma lalo o ka honua me ka ʻole o ka hoʻopuka ʻana i nā hoʻokuʻu ʻino. ʻO ka hoʻemi ʻana o ka walaʻau e hoʻolilo ia i mea kūpono loa. He kūpono ia no ke kūkulu ʻana ma nā kūlanakauhale a i ʻole nā ​​​​wahi i noho nui ʻia."
I ka hoʻomaka ʻana o ka makahiki, ua hoʻolauna ʻo Kubota i kahi prototype mini compact electric excavator ma Kyoto, Iapana. Ua hoʻohui ʻo Hampson: "Ma Kubota, ʻo kā mākou mea nui e hoʻomohala mau i nā mīkini e hoʻokō i nā pono o nā mea kūʻai aku - e hiki ai iā mākou ke hoʻokō i nā mīkini hoʻomohala uila."
Ua hoʻolaha koke aku nei ʻo Bobcat e hoʻolauna ana i kahi moʻo R hou he 2-4 tone o nā mīkini ʻeli liʻiliʻi, me kahi moʻo hou o ʻelima mau mīkini ʻeli liʻiliʻi: E26, E27z, E27, E34 a me E35z. Ua ʻōlelo ka ʻoihana ʻo kekahi o nā hiʻohiʻona koʻikoʻi o kēia moʻo ʻo ia ka manaʻo hoʻolālā o ka paia cylinder o loko (CIB).
Ua ʻōlelo ʻo Miroslav Konas, Luna Hoʻokele Huahana o Bobcat Excavators ma ʻEulopa, ka Hikina Waena a me ʻApelika: "Ua hoʻolālā ʻia ka ʻōnaehana CIB e lanakila ma luna o ka loulou nāwaliwali loa i nā mini-excavators - hiki i nā cylinders boom ke hōʻino maʻalahi i kēia ʻano excavator. No ka laʻana, i ka wā e hoʻouka ai i nā ʻōpala a me nā mea kūkulu hale me nā kalaka, hana ʻia ia e kahi ulia ʻaoʻao me nā kaʻa ʻē aʻe.
"Hoʻokō ʻia kēia ma ka hoʻopuni ʻana i ka cylinder hydraulic i loko o ka ʻōnaehana boom i hoʻonui ʻia, no laila e pale aku ai i nā kuʻi ʻana me ka piko o ka pahi a me ka ʻaoʻao o ke kaʻa. ʻO ka ʻoiaʻiʻo, hiki i ka ʻōnaehana boom ke pale i ka cylinder boom hydraulic ma kēlā me kēia kūlana."
Ma muli o ka nele o nā mea hoʻokele akamai i ka ʻoihana, ʻaʻole i ʻoi aku ka nui o ka hoʻohauʻoli ʻana i ka poʻe e hoʻomau nei. Ua ʻōlelo ʻo Volvo CE ʻo ka hanauna hou o ka mīkini ʻeli liʻiliʻi 6-tona ECR58 F ka mea nona ke keʻena ākea loa i ka ʻoihana.
ʻO ke kahua hana maʻalahi a me ka ʻike maʻalahi e hoʻohana ai e kākoʻo i ke olakino, ka hilinaʻi a me ka palekana o ka mea hoʻohana. Ua hoʻololi ʻia a hoʻomaikaʻi ʻia ke kūlana o ka noho i ka joystick ʻoiai e kau pū ʻia ana - Ua ʻōlelo ʻo Volvo Construction Equipment ua hoʻokomo ʻia ka ʻenehana i loko o ka ʻoihana.
Ua hoʻolālā ʻia ke kaʻa e hāʻawi i ka pae kiʻekiʻe loa o ka maʻalahi o ka mea hoʻohana, me ka pale leo, nā wahi waiho he nui, a me nā awa 12V a me USB. ʻO nā puka makani mua e hāmama piha ana a me nā puka makani ʻaoʻao paheʻe e kōkua i ka ʻike a puni, a he huila lele kaila kaʻa ko ka mea hoʻohana, hōʻike kala ʻelima ʻīniha a me nā papa kuhikuhi maʻalahi e hoʻokele.
He mea nui maoli ka ʻoluʻolu o ka mea hoʻohana, akā ʻo kekahi kumu no ka kaulana nui o ka ʻāpana mini excavator ʻo ia ka hoʻonui mau ʻana o nā mea pono i hāʻawi ʻia. No ka laʻana, loaʻa iā Volvo Construction Equipment's ECR58 nā ʻano mea pono like ʻole e hoʻololi maʻalahi, me nā bākeke, nā mea haki, nā manamana nui, a me nā couplings wikiwiki hou.
I ke kamaʻilio ʻana e pili ana i ke kaulana o nā mīkini ʻeli liʻiliʻi, ua hoʻokūpaʻa ka luna hoʻokele o Off-Highways Research ʻo Chris Sleight i nā mea hoʻopili. Ua ʻōlelo ʻo ia: "Ma ka ʻaoʻao māmā, ua ākea ka laulā o nā mea pono i loaʻa, ʻo ia hoʻi, ʻoi aku ka kaulana o nā mea hana Pneumatic [nā mīkini ʻeli liʻiliʻi] ma mua o nā limahana lima. ʻO kēia kekahi hapa no ka mea kōkua ia i ka hoʻēmi ʻana i ka hopena o ka walaʻau a me ka haʻalulu i nā limahana, a no ka mea hiki iā ia ke hoʻoneʻe i nā limahana mai nā mea hana."
ʻO JCB kekahi o nā OEM he nui e makemake e hāʻawi i nā mea kūʻai aku me nā koho uila no nā mea ʻeli liʻiliʻi
Ua hoʻohui pū ʻo Slater: "Ma ʻEulopa a me ʻAmelika ʻĀkau hoʻi, ke pani nei nā mīkini ʻeli liʻiliʻi i nā ʻano lako ʻē aʻe. Ma ka hopena kiʻekiʻe loa o ka unahi, ʻo kona kapuaʻi liʻiliʻi a me ka hiki ke slewing 360-degere ʻo ia hoʻi ua ʻoi aku ka maikaʻi ma mua o ka hoʻouka ʻana o ka backhoe. ʻOi aku ka kaulana o ka mīkini.
Ua ʻae ʻo Konas o Bobcat i ke koʻikoʻi o nā mea hoʻopili. Ua ʻōlelo ʻo ia: "ʻO nā ʻano bākeke like ʻole a mākou e hāʻawi nei ʻo ia nō nā "mea hana" nui ma nā moʻo hoʻopili like ʻole 25 a mākou e hāʻawi ai no nā mini excavators, akā me ka pala holomua Me ka hoʻomohala ʻana o nā bākeke, ke ulu nei kēia ʻano. Ke lilo nei nā mea pono hydraulic i mea kaulana. ʻO ia ke kumu i hoʻomohala ai mākou i ka ʻōnaehana A-SAC, kahi i hoʻohana ʻia me ʻelima mau kaapuni kōkua kūʻokoʻa ma ka mīkini. Manaʻoʻiʻo mākou e lilo ka Bobcat i brand holomua loa ma ka mākeke e hoʻokele i ia mau mea pono paʻakikī.
"ʻO ka hoʻohui ʻana i nā laina kōkua hydraulic i kau ʻia ma ka lima me ka ʻenehana A-SAC koho hiki ke hāʻawi i kahi ākea o nā koho hoʻopilikino mīkini e hoʻokō i nā koi mea hoʻohui, a laila e hoʻoikaika hou aku i ke kuleana o kēia mau mea ʻeli ma ke ʻano he mau mea paʻa mea hana maikaʻi loa."
Ua hoʻokuʻu ʻo Hitachi Construction Machinery (ʻEulopa) i kahi pepa keʻokeʻo e pili ana i ka wā e hiki mai ana o ka ʻāpana lako liʻiliʻi ʻEulopa. Ua kuhikuhi lākou he 70% o nā mīkini ʻeli liʻiliʻi i kūʻai ʻia ma ʻEulopa ke kaumaha ma lalo o 3 tone. ʻO kēia ma muli o ka loaʻa ʻana o kahi palapala ʻae hiki ke huki maʻalahi i kekahi o nā hiʻohiʻona ma luna o kahi trailer me kahi laikini hoʻokele maʻamau.
Ua wānana ka pepa keʻokeʻo e lilo ka nānā mamao i mea nui i ka mākeke lako hana kūkulu liʻiliʻi, a he ʻāpana koʻikoʻi nā mea ʻeli liʻiliʻi o ia mea. Ua ʻōlelo ka hōʻike: "He mea nui loa ka hahai ʻana i kahi o nā lako liʻiliʻi no ka mea ua hoʻoneʻe pinepine ʻia mai kekahi wahi hana a i kekahi."
No laila, hiki i ka ʻikepili wahi a me nā hola hana ke kōkua i nā mea nona, ʻoi aku hoʻi nā ʻoihana hoʻolimalima, e hoʻolālā, hoʻomaikaʻi i ka pono a hoʻonohonoho i ka hana mālama. Mai kahi manaʻo palekana, he mea nui nō hoʻi ka ʻike pololei o ka wahi - ʻoi aku ka maʻalahi o ka ʻaihue ʻana i nā mīkini liʻiliʻi ma mua o ka mālama ʻana i nā mea nui, no laila ʻoi aku ka maʻamau o ka ʻaihue ʻana i nā mea liʻiliʻi.
Hoʻohana nā mea hana like ʻole i kā lākou mau mīkini ʻeli liʻiliʻi e hoʻolako i nā pahu telematics like ʻole. ʻAʻohe kūlana ʻoihana. Ua hoʻopili ʻia nā mīkini ʻeli liʻiliʻi Hitachi i kāna ʻōnaehana nānā mamao Global e-Service, a hiki ke komo i ka ʻikepili ma o nā kelepona akamai.
ʻOiai ʻo ka wahi a me nā hola hana ke kī i ka ʻike, ua kuhi ka hōʻike e makemake nā mea nona nā lako o ka hanauna e hiki mai ana e nānā i ka ʻikepili kikoʻī. Manaʻolana ka mea nona e loaʻa nā ʻikepili hou aku mai ka mea hana. ʻO kekahi o nā kumu, ʻo ia ke kahe ʻana mai o nā mea kūʻai aku ʻōpio a akamai i ka ʻenehana e hiki ke hoʻomaopopo maikaʻi a kālailai i ka ʻikepili e hoʻomaikaʻi i ka huahana a me ka pono.
Ua hoʻokuʻu koke aku nei ʻo Takeuchi i ka mea ʻeli hydraulic compact TB257FR, ʻo ia ka mea pani o ka TB153FR. Ua loaʻa i ka mea ʻeli hou
ʻO ka boom offset hema-ʻākau i hui pū ʻia me ka lūlū huelo paʻa e ʻae iā ia e wili piha me ka liʻiliʻi o ke kau ʻana.
ʻO ke kaumaha hana o ka TB257FR he 5840 kg (5.84 tons), ʻo ka hohonu o ka ʻeli ʻana he 3.89m, ʻo ka mamao hoʻolōʻihi kiʻekiʻe loa he 6.2m, a ʻo ka ikaika ʻeli bākeke he 36.6kN.
ʻO ka hana boom hema a me ka ʻākau e hiki ai i ka TB257FR ke ʻeli i ka offset ma nā ʻaoʻao hema a me ka ʻākau me ka ʻole o ka hoʻololi ʻana i ka mīkini. Eia kekahi, mālama kēia hiʻohiʻona i nā counterweights hou aʻe e kūlike me ke kikowaena o ka mīkini, no laila e hoʻomaikaʻi ana i ke kūpaʻa.
Ua ʻōlelo ʻia ʻo kekahi pono o kēia ʻōnaehana ʻo ia ka hiki ke waiho ʻia o ka boom ma luna o ke kikowaena, kahi e hiki ai ke hana i kahi wili piha i loko o ka laulā o ke ala. ʻO kēia ka mea kūpono no ka hana ʻana ma nā wahi kūkulu paʻa like ʻole, me nā papahana alanui a me nā alahaka, nā alanui kūlanakauhale a ma waena o nā hale.
"Ua hauʻoli ʻo Takeuchi e hāʻawi iā TB257FR i kā mākou mea kūʻai aku," wahi a Toshiya Takeuchi, Pelekikena o Takeuchi.
