Iyo tambo yekukiya michina chinhu chakakosha chinobvumira mapofu kuti imiswe uye kudzikiswa nyore uye zvakachengeteka. Iyo ine chishandiso chesimbi chinowanzogara pamusoro pechitima chepamusoro chemapofu. Iyo tambo yekukiya yakagadzirirwa kubata tambo yekusimudza munzvimbo iyo bofu iri munzvimbo yaunoda. Nekukwevera pasi pebato rekusimudza, tambo yekuvhara inopinda uye inochengetedza tambo munzvimbo, ichidzivirira mapofu kubva pakufamba. Iyi michina inobvumira mushandisi kukiya mapofu pane chero urefu hwaunoda, nekudaro zvichinyatso kudzora huwandu hwechiedza kupinda mukamuri uye kupa zvakavanzika. Kuti uburitse kongororo yekukiya, zvinyoronyoro dhonza kumusoro kwetambo yekusimudza kusunungura michina, kubvumira mapofu kuti imiswe kana kuderedzwa sezvaunoda.
