Gushushanya ibintu kuri diameter yinyuma yibintu bizunguruka: umuzenguruko uzengurutse ahantu uhuza ibintu bizunguruka.Muri rusange hariho ibizunguruka bisa nkibizunguruka, reba Ishusho ya 70 na 71, kandi ikintu cyitwa "umusatsi wumusatsi" 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 kurigata, reba Ishusho 73. Impamvu: Amavuta yanduye;Ibice bikomeye byinjijwe mumifuka yikiziba bikora nkibice byangiza ku ruziga rusya Umuti: - yemeza ko hashyizweho uburyo bwiza bwo gushiraho - kunoza kashe - gushungura 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 no gukurura ibimenyetso.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 n'amasoko - Kugabanya gukina - Kugenzura umutwaro uhagije nubwo ari ubusa - Kunoza amavuta.

Kwitwaza ibintu byo gushushanya: Kubintu bitandukanya silindrike ya roller cyangwa ibyuma bifata ibyuma bifata ibyuma, ibizunguruka hamwe n'inzira nyabagendwa byabuze ibikoresho bisa 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.Birateye akaga cyane mugihe kwimura ibice byinshi (mugihe uruzitiro rwinshi rufite impeta yimbere hamwe ninteko izunguruka isunikwa mumuzingo winyuma umaze gushyirwaho mumazu yububiko).Umuti: - Koresha ibikoresho byubushakashatsi bikwiye - Irinde kudahuza - Niba bishoboka, hindukirira buhoro mugihe ushyiramo ibice.
