ʻO nā mea ʻeli liʻiliʻi kekahi o nā ʻano mea hana wikiwiki loa, a ʻike ʻia ko lākou kaulana. Wahi a ka ʻikepili mai Off-Highway Research, ua hōʻea nā kūʻai honua o nā excavators liʻiliʻi i ka helu kiʻekiʻe loa i ka makahiki i hala, ma mua o 300,000 mau ʻāpana.
ʻO ka mea maʻamau, ua hoʻomohala ʻia nā mākeke nui no nā micro-excavators, e like me Iapana a me Western Europe, akā ua hoʻonui ʻia ko lākou kaulana i nā ʻoihana e ulu nei i nā makahiki i hala. ʻO ka mea kaulana loa o kēia mau mea ʻo Kina, ʻo ia ka mākeke mini excavator nui loa o ka honua.
Ke noʻonoʻo nei hiki i nā mini-excavators ke hoʻololi i ka hana lima, ʻaʻohe hemahema o nā limahana ma nā ʻāina nui loa o ka honua. He loli kāhāhā paha kēia. ʻOiai ʻaʻole like ke kūlana me ka mākeke Kina, e ʻoluʻolu e nānā i ke kolamu "China 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 nā mīkini liʻiliʻi a ʻoi aku ka paʻakikī me ka uila ma mua o ka mana diesel kuʻuna. I kēia hihia, ʻoi aku hoʻi ma nā kikowaena kūlanakauhale o nā ʻoihana holomua, maʻa mau nā kānāwai koʻikoʻi no ka walaʻau a me nā hoʻokuʻu.
ʻAʻohe hapa o nā mea hana OEM e hoʻomohala ana a hoʻokuʻu paha i nā mea ʻeli uila uila-e like me Ianuali 2019, ua hoʻolaha ʻo Volvo Construction Equipment Corporation (Volvo CE) ma ka waena o 2020, e hoʻomaka ana e hoʻomaka i kahi ʻano o nā mea hoʻoheheʻe uila uila (EC15 a i EC27). ) A me nā huila huila (L20 a i L28), a ho'ōki i ka hoʻomohala hou o kēia mau hiʻohiʻona e pili ana i nā ʻenekini diesel.
ʻO kekahi OEM e ʻimi nei i ka mana ma kēia kahua lako ʻo JCB, i lako me ka 19C-1E miniature electric excavator. Hoʻohana ʻia ʻo JCB 19C-1E e ʻehā mau pākahi lithium-ion, hiki ke hāʻawi i 20kWh o ka mālama ʻana i ka ikehu. No ka hapa nui o nā mea kūʻai excavator liʻiliʻi, hiki ke hoʻopau ʻia nā hoʻololi hana āpau me ka uku hoʻokahi. ʻO ka 19C-1E ponoʻī he kumu hoʻohālike ikaika me ka hoʻokuʻu ʻole ʻana i ka wā e hoʻohana ai a ʻoi aku ka mālie ma mua o nā mīkini maʻamau.
Ua kūʻai aku ʻo JCB i ʻelua mau hiʻohiʻona i ka hale kanu J Coffey ma Lākana. Ua ʻōlelo ʻo Tim Rayner, Luna Hoʻokele o ke Keʻena ʻOihana ʻo Coffey: "ʻO ka pōmaikaʻi nui ʻaʻole i hoʻokuʻu ʻia i ka wā e hoʻohana ai. Ke hoʻohana nei i ka 19C-1E, ʻaʻole e hoʻopilikia ʻia kā mākou limahana i nā hoʻokuʻu diesel.
ʻO kekahi OEM e kālele ana i ka uila ʻo Kubota. "I nā makahiki i hala iho nei, ua piʻi wikiwiki ka kaulana o nā mea 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 hoʻoikaika nui ma hope o kēia, ʻo ia nā mea uila e hiki ai i nā mea hana ke hana i nā wahi haʻahaʻa haʻahaʻa i kuhikuhi ʻia. Hiki i ke kaʻa ke hiki ke hana i nā hana i loko o nā wahi paʻa i lalo o ka honua me ka ʻole o ka hana ʻana i nā hoʻokuʻu ʻino.
I ka hoʻomaka ʻana o ka makahiki, ua hoʻokumu ʻo Kubota i kahi prototype mea hoʻoheheʻe uila liʻiliʻi 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 ka mea kūʻai aku - nā mīkini hoʻomohala uila e hiki ai iā mākou ke hana."
Ua hoʻolaha aku nei ʻo Bobcat e hoʻolauna i kahi pūʻulu hou 2-4 ton R o nā mea ʻeli liʻiliʻi, me kahi pūʻulu hou o ʻelima mau mea hoʻoheheʻe paʻa: E26, E27z, E27, E34 a me E35z. Wahi a ka hui ʻo kekahi o nā hiʻohiʻona koʻikoʻi o kēia pūʻulu ka manaʻo hoʻolālā o ka paia cylinder i loko (CIB).
Ua ʻōlelo ʻo Miroslav Konas, Product Manager o Bobcat Excavators ma ʻEulopa, ka Middle East a me ʻApelika: "Ua hoʻolālā ʻia ka ʻōnaehana CIB e lanakila ai i ka loulou nāwaliwali loa i nā mini-excavators-hiki i nā cylinders boom ke hōʻino maʻalahi i kēia ʻano o ka excavator.
"Hoʻokō ʻia kēia ma ka hoʻopaʻa ʻana i ka cylinder hydraulic i loko o ka hoʻolālā boom lōʻihi, a laila e pale aku ai i ka hui ʻana me ka piko o ka lau a me ka ʻaoʻao o ke kaʻa.
Ma muli o ka nele o nā mea hana akamai i ka ʻoihana, ʻaʻole i ʻoi aku ka nui o ka hauʻoli o ka poʻe hoʻomau. Ua ʻōlelo ʻo Volvo CE ʻo ka hanauna hou o 6-ton ECR58 F compact excavator i loaʻa ka kaʻa ākea loa i ka ʻoihana.
Kākoʻo ke kahua hana maʻalahi a me ka ʻike hoʻohana i ke olakino, hilinaʻi a me ka palekana o ka mea hoʻohana. Ua hoʻololi ʻia a hoʻomaikaʻi ʻia ke kūlana o ka noho i ka lāʻau hauʻoli i ka wā e hoʻokuʻu pū ʻia ana-Ua ʻōlelo ʻo Volvo Construction Equipment ua hoʻokomo ʻia ka ʻenehana i ka ʻoihana.
Hoʻolālā ʻia ke kaʻa e hāʻawi i ka pae kiʻekiʻe o ka ʻoluʻolu o ka mea hoʻohana, me ka insulation leo, nā wahi mālama he nui, a me nā awa 12V a me USB. Hāmama piha nā puka makani i mua a me nā puka makani ʻaoʻao hoʻoheheʻe e hoʻomaʻamaʻa i ka ʻike a puni, a loaʻa i ka mea hoʻohana ke kaʻa lele lele, ʻelima iniha hōʻike kala a me nā menus maʻalahi ke hoʻokele.
He mea koʻikoʻi ka hōʻoluʻolu o ka mea hana, akā ʻo ke kumu ʻē aʻe no ka laha nui ʻana o ka māhele mini excavator ʻo ia ka hoʻonui mau ʻana o ka nui o nā lako i hāʻawi ʻia. No ka laʻana, loaʻa i ka Volvo Construction Equipment's ECR58 nā ʻano mea maʻalahi e hoʻololi, e like me nā bākeke, nā haʻihaʻi, nā manamana lima, a me nā hoʻohui wikiwiki hou.
Ke kamaʻilio nei e pili ana i ka kaulana o nā mea ʻeli liʻiliʻi, ʻo ka luna hoʻomalu o Off-Highways Research ʻo Chris Sleight i hoʻoikaika i nā mea pili. Ua ʻōlelo ʻo ia: "Ma ka ʻaoʻao māmā, ʻoi aku ka laulā o nā mea hana i loaʻa, ʻo ia hoʻi, ʻoi aku ka kaulana o nā mea hana Pneumatic ma mua o nā limahana lima. ʻO kēia kekahi no ka mea e kōkua i ka hōʻemi ʻana i ka hopena o ka walaʻau a me ka haʻalulu i nā limahana, a no ka mea hiki ke hoʻoneʻe i nā limahana mai nā mea hana. "
ʻO JCB kekahi o nā OEM e makemake ana e hāʻawi i nā mea kūʻai aku i nā koho uila no nā mini excavators
Ua hoʻohui hou ʻo Slater: "Ma ʻEulopa a me ʻAmelika ʻĀkau, ke hoʻololi nei nā mea ʻeli liʻiliʻi i nā ʻano mea hana ʻē aʻe. Ma ka hopena kiʻekiʻe loa o ka pālākiō, ʻo kona kapuaʻi liʻiliʻi a me 360-degree slewing hiki ke ʻoi aku ka maikaʻi ma mua o ka hoʻouka ʻana i ka backhoe. Ua kaulana ka mīkini. "
Ua ʻae ʻo Bobcat's Kona i ke koʻikoʻi o nā mea pili. Ua ʻōlelo ʻo ia: "ʻO nā ʻano kīʻaha like ʻole a mākou e hāʻawi ai ʻo ia ka "mea hana" nui i ka 25 mau mea hoʻopili like ʻole a mākou e hoʻolako ai no nā mini excavators, akā me ka ʻoi aku ka holomua Me ka ulu ʻana o nā bākeke, ke ulu nei kēia ʻano. e hana i ia mau mea paʻakikī.
"ʻO ka hui pū ʻana i nā laina kōkua hydraulic i hoʻopaʻa ʻia i ka lima me ka ʻenehana A-SAC koho hiki ke hāʻawi i kahi ākea o nā koho hoʻoponopono mīkini e hoʻokō i nā koi ʻokoʻa, a laila e hoʻonui hou i ka hana o kēia mau excavators ma ke ʻano he mea paʻa pono."
Ua hoʻokuʻu aku ʻo Hitachi Construction Machinery (Europe) i kahi pepa keʻokeʻo e pili ana i ka wā e hiki mai ana o ka ʻāpana lako compact European. Ua kuhikuhi lākou he 70% o nā mea ʻeli liʻiliʻi i kūʻai ʻia ma ʻEulopa ma lalo o 3 tons. ʻO kēia ma muli o ka loaʻa ʻana o ka ʻae hiki ke huki maʻalahi i kekahi o nā hiʻohiʻona ma kahi trailer me kahi laikini kaʻa maʻamau.
Wahi a ka pepa keʻokeʻo, ʻoi aku ka nui o ka mākaʻikaʻi mamao i ka mākeke lako hana paʻa, a ʻo nā mini excavators kekahi ʻāpana koʻikoʻi. Ua ʻōlelo ka hōʻike: "He mea koʻikoʻi ka nānā ʻana i kahi o nā mea hana paʻa no ka mea e neʻe pinepine ʻia mai kahi kahua hana i kekahi.
No laila, hiki i ka ʻikepili wahi a me nā hola hana ke kōkua i nā mea nona, ʻoi aku ka hoʻolimalima ʻana i nā ʻoihana, hoʻolālā, hoʻomaikaʻi maikaʻi a hoʻonohonoho i ka hana mālama.

Hoʻohana nā mea hana like ʻole i kā lākou ʻeli liʻiliʻi e hāʻawi i nā kime telematics like ʻole. ʻAʻohe kūlana ʻoihana. Ua hoʻopili ʻia nā mea ʻeli mini Hitachi i kāna ʻōnaehana nānā mamao Global e-Service, a hiki ke kiʻi ʻia nā ʻikepili ma o nā kelepona.
ʻOiai ʻo ka wahi a me nā hola hana ke kī nui i ka ʻike, manaʻo ka hōʻike e makemake ana nā mea nona nā lako hana e nānā i ka ʻikepili kikoʻī.

Ua hoʻokuʻu ʻo Takeuchi i ka TB257FR compact hydraulic excavator, ʻo ia ka mea pani i ka TB153FR. Ua loaʻa i ka excavator hou
ʻO ka puʻupuʻu offset hema-akau i hui pū ʻia me ke kowali ʻana o ka huelo paʻa e ʻae iā ia e hoʻohuli piha me ka liʻiliʻi liʻiliʻi.
