Imyenda ikorwa ninganda zubaka kugirango zihuze ibice bitandukanye. Ibice bitandukanye bifite imiterere itandukanye, kuburyo butandukanye bwubwoko butandukanye bwatejwe imbere. Ibikurikira byerekana ibiranga ibyuma bifata amajwi:

1. Ibiranga imiterere yaicyuma gifata imashini

Hejuru yikizunguruka gifatanyirijwe hamwe gifite icyuma gifata amajwi, kikaba ari igikoresho gifata ibyuma bigizwe na radiyo. Impeta y'imbere n'inyuma yo kwifata byafashe inzira nyabagendwa. Kubera ko diameter yambukiranya ibice bya muzingo ari ngufi, ariko uburebure ni burebure, bwiswe icyuma gifata imashini gikurikije imiterere.

2.Ibiranga ibyuma bifata imashini

Nubwo igice cya diametre yiki gice ari kigufi cyane, ingano nuburemere bwigice ubwacyo ni gito, ariko imiterere yacyo ya radiyo irahuzagurika kandi ifite ubushobozi bwo gutwara ibintu byinshi, bityo ubunini bwimbere bwimbere nubushobozi bwikigereranyo ugereranije nubundi bwoko bwa Imyifatire, diameter yo hanze Ntoya, cyane cyane ikwiranye nubunini bwimbogamizi zububiko bwimikorere.

Kurundi ruhande, inzira nyabagendwa yimpeta yinyuma yikurikiranya nayo igira uruhare runini: ubushobozi bwimitwaro yikintu bwiyongera mukongera inguni yubuso.

Byongeyeho ,.rollerifite ubuhanga buhanitse kandi bukomeye hejuru, kuburyo ishobora kwihanganira imbaraga inshuro nyinshi kurenza imbaraga zayo. Umutekano wo gukoresha, guhuza cyane no gukora neza.

Ubushobozi bwumurongo umwe wapanze uruziga rufite kwihanganira imitwaro ya axial biterwa nu mpande zifatika, ni ukuvuga inguni yimpeta yo hanze. Inguni nini, nubushobozi bwa axial umutwaro. Byakoreshejwe cyane bifata ibyuma bifata imashini ni umurongo umwe wapanze uruziga. Mu ruziga rw'imbere rw'imodoka, harakoreshwa ntoya-nini-ebyiri-yimirongo ifatanye. Imirongo ine yapakishijwe imashini ikoreshwa mumashini ziremereye nkurusyo runini rukonje kandi rushyushye.
