Iyi ndi gulu la zida zolumikizirana za AB Ring, zomwe zidapangidwa m'maseti 15, kwa makasitomala athu aku Canada. Mitundu yosiyanasiyana ya zida zolumikizirana, gulu laling'ono komanso nthawi yochepa ndizo zinthu zazikulu zomwe makampani opanga makina amakono amapanga. Kuwoneka kwa izi kumalimbikitsa kupanga lingaliro la zida zosinthasintha komanso chitukuko cha ukadaulo. Pamene nthawi yokonzanso zinthu ikufupika, momwe mungasinthire mwachangu kuchokera ku mitundu yakale kupita ku mitundu yatsopano ndikufupikitsa nthawi ya polojekitiyi ndiye njira yofufuzira ya miyala yamtengo wapatali iliyonse.

Cholumikizira cholumikizira makamaka chimaphatikizapo mbale ya pansi, cholumikizira chapadera, njira yothandizira, ndi makina owongolera magawo angapo. Mbale yapansi ndi chassis ya zigawo zolumikizira, mfuti yolumikizira yokha, chonyamulira ndi zigawo zina zolumikizira. Ndi gawo loyambira la cholumikizira cholumikizira, ndipo kulondola kwake kumakhudza mwachindunji kulondola kwa njira yoyikira. Makina ozungulira olumikizira okha ndi mtundu wa zida zolumikizira zokha zomwe zimatha kumaliza mitundu yonse ya ma weld ozungulira ndi annular. Angagwiritsidwe ntchito pachitsulo cha kaboni, chitsulo chopanda alloy, chitsulo chosapanga dzimbiri, aluminiyamu ndi alloy yake ndi zinthu zina zapamwamba kwambiri, ndipo amatha kusankha argon arc welding (waya kapena osati waya), kusungunula ma electrode gasi welding, plasma welding ndi mphamvu zina zolumikizira kuti apange dongosolo lolumikizira lolumikizira lozungulira. Itha kugwiritsidwa ntchito kwambiri pakulumikiza silinda ya hydraulic, chimango chowongolera magalimoto, shaft yoyendetsa, silinda yosungira gasi, zotengera zamankhwala ndi zamankhwala, matanki a gasi osungunuka, zida zozimitsira moto, ma roller ndi silinda yosungira madzi yopangira migodi ndi mizere yopangira, ndi zina zotero.
