Ikibumbano gikozwe mu cyuma ni ubwoko bwa convoyeur, ni igice cyingenzi cya convoyeur, icyuma gishobora kuzamura imikorere yimikorere ya sisitemu ya convoyeur, kugirango irinde icyuma cyangirika, ariko kandi ikarinda umukandara wa convoyeur kunyerera, kugirango guhuza umukandara n'umukandara bikore. Ubwiza bwa roller ikozweho na rebero nayo yibasiwe nibintu bitandukanye, nko guhitamo ibicuruzwa bya reberi, ikoranabuhanga ryubwubatsi, urwego rwikoranabuhanga rwabakozi bakoresheje reberi narwo rufite ingaruka runaka kumiterere ya reberi. Abakora tekinoroji yo gutwika reberi, tekinoroji ya reberi isanzwe ifite ibishishwa bishyushye hamwe nubushuhe bukonje, ariko isoko nyamukuru yabaye inzira ishyushye y’ibirunga yasimbujwe n’imiti ikonje ikonje;

Amenyo yometseho amenyo ntagomba kuba ibisigara bisigaye cyangwa kwambara gukomeye, isuka ifite uruziga rutambitse rwindege yambara cyane: ikibanza kiri munsi ya milimetero makumyabiri na zibiri, ntigishobora kurenza milimetero eshanu; mugihe ikibanza kirenze cyangwa kingana na milimetero makumyabiri na zibiri, ntigishobora kurenga milimetero esheshatu (irashobora gukoreshwa kugirango uringanize urunigi ruzunguruka rushyizwe kumasoko, reba hejuru yumurongo wuruziga hamwe na hub yintera). Isoko ya reberi ikozweho na reberi ntishobora gukorwa icyarimwe hariho tamping axial. Inshuro ebyiri zuzuzanya hamwe no gukuraho ikadiri kumpande zombi bigomba kuba byujuje ibisabwa mubishushanyo, muri rusange ntibirenza milimetero eshanu. Isahani yometseho reberi isahani, gutandukanya urunigi nta guhindura, nta kintu cyo gukoraho ikarita mugihe cyo gukora, ururimi ntiruzagira ibice, kwambara ntarengwa ntibishobora kurenga makumyabiri kwijana ryubugari. Ikintu cya elastike cyo guhuza, ibikoresho nubunini bwa shear pin bigomba kuba bihuye nibiteganijwe mubyangombwa bya tekiniki. Inkinzo ntigira ibice, nta deformasiyo, kandi irahujwe rwose.

Nka reberi yometseho reberi kubikoresho byicyuma, mugikorwa cyo kubyara ingaruka ziterwa no kunyeganyega hamwe nizindi mbaraga zishyize hamwe, bizaganisha kumuzingo wambaye biti nibindi byananiranye. Kubijyanye no gusana umukandara wa convoyeur, uburyo gakondo bwo kugaragara, gutera amashyuza, guswera feri, nibindi, ariko haribintu bimwe bitagenda neza: guhangayikishwa nubushyuhe buterwa nubushyuhe bwo hejuru bwo gusudira kwuzuza ntibishobora kuvaho burundu, byoroshye guteza ibyangiritse, bikaviramo kunama cyangwa kuvunika ibice; no gusya gusya ukoresheje umubyimba wububiko ni bike, byoroshye kuzimya, kandi uburyo bubiri bwavuzwe haruguru ni ibyuma kugeza ibyuma byo gusana ibyuma, ntibishobora guhindura umubano "ukomeye-bigoye", mugihe habaye guhuza bigoye-bigoye, uruziga ntirushobora gusimburwa, kandi uruziga ntirushobora gusimburwa. Uburyo bubiri bwavuzwe haruguru ni ugusana ibyuma hamwe nicyuma, kidashobora guhindura umubano "bigoye-bigoye", kandi bitewe ningaruka zinguvu zinyuranye, bizakomeza kongera kwambara ibizunguzungu.
