Yang'anani kwambiri pa zigawo zazikulu za chassis za mini excavators

Chifukwa cha kupita patsogolo kwa mizinda padziko lonse lapansi komanso kutulutsidwa kwa kufunikira kwa mapulojekiti ang'onoang'ono, kufunikira kwa ma mini-excavator kwawonjezeka chifukwa cha kusinthasintha kwawo komanso kusavuta kwawo. Chassis imagwira ntchito ngati "maziko oyendera" a makina awa, komanso magwiridwe antchito a zigawo zake zinayi zazikulu -ma track roller, zogwirira ntchito, zopukutira zothandizira, ndi mphete za mano - zimatsimikiza momwe zida zimagwirira ntchito bwino. Pakadali pano, kuchuluka kwa zigawo za chassis za ma mini-excavator ku China kumaposa 90%. Chifukwa cha kuchuluka kwa zida zotumizidwa kunja, zigawo zazikuluzi zagwiritsidwa ntchito kwambiri m'maiko ndi madera ambiri padziko lonse lapansi.

Zigawo zinayi zazikulu chilichonse chimagwira ntchito zake ndipo chimagwira ntchito limodzi mogwirizana: ma rollers othandizira amanyamula kulemera kwa makina onse ndikugawa mofanana ku njanji, kuteteza kuti nthaka yofewa isagwe;magudumu otsogoleratsogolerani njira ya njanji ndikusintha mphamvu yake, kupewa kupotoka ndi kulumpha kwa unyolo; ma rollers onyamula katundu amathandizira gawo lapamwamba la njanji, kuchepetsa kugwedezeka ndi kuwonongeka, kuonetsetsa kuti mphamvu imafalikira bwino; mphete ya giya imatumiza mphamvu polumikizana ndi njanji, kuyendetsa zida kuti ziyende, ndipo ndiye maziko a mphamvu.

Padziko lonse lapansi, mayiko omwe zigawo za chassis izi zimagwiritsidwa ntchito kwambiri ndi ku Europe, America, ndi Asia-Pacific. United States, monga msika waukulu padziko lonse lapansi, idawona kutumizidwa kwa ma mini-excavator opitilira 48,000 mu 2023, makamaka kuti akonzenso nyumba ndi kukonza ma city. Mayiko aku Europe monga Germany ndi France, okhala ndi malamulo okhwima okhudza chilengedwe komanso msika wobwereka wachikulire, ali ndi kufunikira kwakukulu kwa zigawo za chassis. Japan, monga malo obadwira ma mini-excavator apamwamba, ili ndi zofunikira zambiri zosinthira zigawo za chassis, zomwe zimagwiritsa ntchito ulimi ndi zomangamanga zolondola za m'mizinda. Kuphatikiza apo, mayiko aku Southeast Asia monga Indonesia ndi Thailand, komanso mayiko ambiri ku Africa, akhala madera omwe ali ndi chiwopsezo chachikulu cha kukula kwa ntchito za zigawo za chassis, chifukwa cha zomangamanga ndi zosowa zaulimi. Zigawo za chassis zodziwika bwino ku China zili ndi gawo lalikulu chifukwa cha mtengo wawo wotsika.
