Gushushanya ibintu kuri diametre yinyuma yibintu bizunguruka: umuzenguruko uzenguruka mukarere kahuza ibintu bizunguruka.Muri rusange hariho ibizunguruka bisa nkibizunguruka, reba Ishusho ya 70 na 71, kandi ikintu cyitwa "umusatsi" gikunze kugaragara kumipira, reba Ishusho 72. Ntabwo ugomba kwitiranywa nuruhande (reba igice 3.3.2.6).Impande zumuhanda zakozwe nuruhande rwiruka ziroroshye kubera guhindura plastike, mugihe igishushanyo gifite impande zikarishye.Ibice bikomeye bikunze gushirwa mumifuka yikiziriko, bigatera uburibwe, reba Ishusho 73. Impamvu: Amavuta yanduye;Ibice bikomeye byinjijwe mumifuka yikiziba bikora nkibice byangiza ku ruziga rusya Umuti: - yemeza ko ibintu byashyizweho neza - biteza imbere kashe - muyungurura amavuta.

Ibimenyetso byerekana ibintu: kuzunguruka ibintu kunyerera, cyane cyane binini kandi biremereye, nka INA yuzuye yuzuza ibizunguruka.Kunyerera inzira nyabagendwa cyangwa ibintu bizunguruka.Ibikoresho akenshi byubaka hamwe nibimenyetso byo gukurura.Mubisanzwe ntibigabanijwe neza hejuru ariko ahantu, reba Ishusho ya 74 na 75. Gukuramo utuntu duto bikunze kuboneka, reba igice 3.3.2.1 “Umunaniro kubera amavuta make”.Impamvu: - Iyo umutwaro uri muke cyane kandi amavuta ni mabi, ibintu bizunguruka biranyerera mumihanda.Rimwe na rimwe, kubera ko ahantu ho gutwara ari hato cyane, umuzingo wihuta cyane mu mufuka w’akazu mu gace katarimo imizigo, hanyuma ukihuta cyane iyo winjiye mu gace kegeranye.- Impinduka zihuse mumuvuduko.Ingamba zo gukosora: - Koresha ibyuma bifite ubushobozi buke bwo kwikorera - Banza ushyireho ibicuruzwa, urugero hamwe nisoko - Kugabanya gukina - Kugenzura umutwaro uhagije nubwo waba ari ubusa - Kunoza amavuta.

Kwiyerekana gushushanya: Kubintu bitandukanya silindrike ya roller cyangwa ibyuma bifata imashini, ibizunguruka hamwe n'inzira nyabagendwa byabuze ibikoresho bigereranywa na axe kandi bihwanye nibintu bizunguruka.Rimwe na rimwe, hari ibimenyetso byinshi byerekana icyerekezo.Uru rutonde rusanzwe ruboneka gusa mu cyerekezo kizengurutse hafi ya B / d aho kuba umuzenguruko wose, reba Ishusho ya 76. Impamvu: Kudahuza no gukandagirana mugihe ushyizeho ferrule imwe na ferrule hamwe nibintu bizunguruka.Birashobora guteza akaga cyane iyo kwimura ibice byinshi (mugihe uruzitiro rwinshi rufite impeta yimbere hamwe ninteko izunguruka isunikwa mumuzingo winyuma umaze gushyirwaho mumazu yububiko).Umuti: - Koresha ibikoresho byubaka bikwiye - Irinde kudahuza - Niba bishoboka, hindukirira buhoro mugihe ushyira ibice.
