Mu kibaho cy'umuriro (PCB), PCB) no kuramba ni ngombwa. Ikintu cyingenzi cyibikorwa ni kashe ya PCB, kandi guhitamo ibikoresho kubice kashyizweho ka kashyizweho kashe birashobora guhindura ibintu byumusaruro no gukora neza. Ibikoresho bibiri bisanzwe bikoreshwa muriki gice ni granite na steel, buriwese hamwe nibyiza byabo nibibi.
Granite ibice bizwiho guharanira inyungu zabo bidasanzwe. Ubucucike bw'ibuye karemano butanga urufatiro rukomeye rugabanya ubukana mugihe cyo gukandagira, bityo rukomeza kwiyongera no kugabanya kwambara neza kubikoresho bya kashe. Uku gushikama ni ingirakamaro cyane cyane mugusaba byihuta cyane, aho no guhagarara nabi bishobora gutera nabi no kubuza. Byongeye kandi, granite irwanya kwaguka mu bushyuhe, iregwa imikorere ihamye ku bushyuhe butandukanye, bunenga ku bidukikije aho ubushyuhe bufite impungenge.
Kurundi ruhande, ibice, bikundwa kubwimbaraga zabo no kuramba. Ibice by'ibyuma ntibishoboka ko kuri granite, bikabatera guhitamo kwizewe kumusaruro mwinshi. Byongeye kandi, ibice by'icyuma birashobora gukoreshwa byoroshye kandi byihariye kugirango byubahirize ibisabwa byihariye, gutanga ibishushanyo byoroshye kuri granite idashobora guhura. Ariko, ibice byicyuma bikunze kugaragara ku maso no ku gakondo, bishobora kuba bibi cyane mu buryo buhebuje cyangwa ibidukikije byangiza imivumba.
Mugihe ugereranya imikorere ya granite na steel kugirango hashyizweho ingamba za SCB, icyemezo cyanyuma giterwa nibikenewe byihariye mubikorwa byo gukora. Kubikorwa aho ibisobanuro no gushikama kunegura, granite birashobora kuba amahitamo meza. Ibinyuranye, kuko ibyo bikorwa bisaba kuramba no guhuza n'imihindagurikire, Icyuma birashobora kuba byiza. Gusobanukirwa imitungo idasanzwe ya buri kintu ni ingenzi kubabikora bigamije kunoza inzira zabo za PCB.
