Icyuma gikonje gikonje (icyuma cya CR) ni icyuma gishyushye gikonje cyatunganyijwe mu buryo burambuye.
Isahani y'icyuma ikonje 'izungurutse' ikunze gukoreshwa mu gusobanura inzira zitandukanye zo kurangiza—nubwo, mu by'ukuri, 'izungurutse ikonje' ikoreshwa gusa ku mpapuro zishyirwa hagati y'imizingo. Ibintu nk'imirongo cyangwa imiyoboro 'irakururwa,' ntabwo izungurutswa. Izindi nzira zo kurangiza ikonje zirimo guhindura, gusya no gusiga irangi—buri kimwe muri byo gikoreshwa mu guhindura ibikoresho bishyushye bisanzweho mo ibintu binonosoye kurushaho.
Igikoresho cy'icyuma gikonje cya ST12 gikunze kugaragazwa n'ibi bikurikira:
1. Icyuma gikonje gikozwe mu cyuma gifite ubuso bwiza kandi bukozwe neza kandi bushobora kwihanganira ibintu byinshi
2. Ahantu horoshye hakunze kuba hari amavuta menshi iyo ukozeho mu cyuma cya CR
3. Utubati tuba ari ingenzi kandi dufite impande enye, kandi akenshi tuba dufite impande n'imfuruka bisobanutse neza
4. Imiyoboro ifite uburyo bwo guhuza neza no kugororoka, ikozwe mu bikoresho bikonje bizinze.
5. Ibyuma bikonje bizingiye bifite imiterere myiza y'ubuso kurusha icyuma gishyushye, ntabwo bitangaje kuba icyuma gikonje gikunze gukoreshwa mu buryo bunoze cyangwa aho ubwiza ari ingenzi. Ariko, bitewe n'uburyo bwo kongera gutunganya ibikoresho bikonje, biza ku giciro kiri hejuru.
Ku bijyanye n'imiterere yabyo, ibyuma bikonje bikunze gukomera kandi bikomeye kurusha ibyuma bisanzwe bikonje bizinze. Ibi biterwa nuko kurangiza ibyuma bikonje bizinze bitanga umusaruro ukomeye. Ni ngombwa kumenya ko ubu buryo bw'inyongera bushobora no guteza ibibazo imbere mu bikoresho. Mu yandi magambo, iyo ukoze ibyuma bikonje - byaba ari ukubikata, kubisya cyangwa kubisudira - ibi bishobora kurekura imvururu no gutera guhindagurika ku buryo butunguranye.

Porogaramu z'ibicuruzwaIbyuma bikonje bya ST12, ibikoresho by'ibyuma bikonje byakozwe mu buryo bwa cold: ubwubatsi, gukora imashini, gukora amakontena, kubaka amato, kubaka ikiraro. Ibyuma bya CR bishobora kandi gukoreshwa mu gukora ubwoko butandukanye bw'amakontena.
Icyuma cya ST12 gishobora kandi gukoreshwa mu gutwikira itanura, icyuma gikozwe mu ifuru, icyuma gikozwe mu kiraro n'imodoka, icyuma gikozwe mu cyuma gito, icyuma gikozwe mu nganda, icyuma gikozwe mu ifuru, icyuma gikozwe mu ifuru, icyuma gikozwe mu ifuru, icyuma gikozwe mu gikoresho gishyushya umuvuduko, icyuma gikozwe mu ifuru, ibice bya traktori, icyuma gikozwe mu ifuru n'ibikoresho byo gusudira.
