Umurongo umeze umurongo wa metallurgical ni gearbox iremereye yinganda zumwihariko kugirango ibintu bikaze byo gukora inganda za metallurgy, harimo no kwicwa, no gutangiza urusyo. Kurangwa na gahunda yacyo ibangikanye (umurongo "umurongo"), iki gitsina kiranga hamwe n'amavuta yo gukomera, imihangayiko y'amabuye y'agaciro kugira ngo ihungabanye ikabije, guhangayika. Igishushanyo cyacyo cyoroshye, cya modular cyifatanije na sisitemu yo kudoda hamwe no guhiga ku gahato kugirango habeho ibikorwa byizewe.
Kugabanya kwemerwa Igishushanyo mbonera cya modular kandi gishobora gukosorwa hakurikijwe ibisabwa mububasha bwibikoresho bitandukanye. Agasanduku imiterere yarateguye kandi ifite imikorere myiza yubushyuhe nubushobozi bwumutungo wubushyuhe, kandi burashobora kumenyera ubushyuhe bwinshi bwakozwe nubushyuhe buhoraho, kuzunguruka nibindi bikorwa. Siar Staff yatunganijwe neza kandi igarindwa neza, kandi ikora neza kandi ifite urusaku ruto, rukwiranye cyane nimashini za Metallurgive hamwe nibikoresho bikomeye byoherejwe. Ibicuruzwa bishyigikira uburyo butandukanye bwo kwishyiriraho ibintu byihariye byibintu bitandukanye bya Porogaramu nkibintu bya Metallurgique, imashini zigororotse, hamwe na rusyo.
Ibiranga imibare ibiri hamwe nibisohoka bikubye kabiri hamwe nibisohoka bya synchrous, gusiga amavuta, umutwaro uhamye, ubushobozi bwikirere, ubushobozi bwikirenga, hamwe no kurwanya ingaruka zikomeye.
