A ucango yeka (nayo ukumiswa emnyango, ukuma emnyango okanye umnyango wedge) sisixhobo okanye isixhobo esisetyenziselwa ukugcina ucango luvulekile okanye luvaliwe, okanye ukuthintela ucango ekuvulekeni ngokubanzi. Eli gama linye lisetyenziselwa ukubhekisa kwisilayiti esibhityileyo esakhelwe ngaphakathi kwisakhelo somnyango ukukhusela ucango ukuba lungajiki xa luvaliwe. Istopstop (esetyenzisiweyo) isenokuba sisibiyeli esincinci okanye isiqwenga sesinyithi esimalunga nama-90 esetyenziswe kwisakhelo somnyango sokumisa umnyango ekujijeni (kwicala lesibini) kunye nokuguqula loo mnyango uye kwicala elinye (in-swing Push okanye ukukhupha ngaphandle)Ukubamba iingcango zivulekile

Umnyango unokumiswa ngumphezulu wento into enzima enzima, enje ngerabha, ebekwe ecaleni komnyango. Ezi ndawo zokuma ziye zaphuculwa ikakhulu.

[1] Ngokwembali, izitena ezikhokelayo bezikade zikhethwa xa zikhona.

[2 Nangona kunjalo, njengoko ityhefu yobunkokeli ibonakalisiwe, olu setyenziso luyekisiwe ngamandla.

[3] Enye indlela kukusebenzisa i ukuma emnyangooludaka oluncinci lomthi, irabha, ilaphu, iplastiki, umqhaphu okanye enye into. Iidges ezenziwe ngezi zinto zihlala zifumaneka. I-wedge ikhatywa ibekwe endaweni kwaye amandla ezantsi omnyango, ngoku axineneyo anyuka esiya emnyango, unika ukungqubana okwaneleyo ukuze kungagungqi.

[4] Isicwangciso sesithathu kukuxhobisa umnyango ngokwawo ngesixhobo sokumisa. Kule meko, ibha yesinyithi emfutshane efakwe irabha, okanye enye into exubana kakhulu, incanyathiselwe kwihenjisi kufutshane emazantsi omnyango ejongene nehenjisi yomnyango nakwicala lomnyango kwicala elivalekileyo. Xa ucango luza kugcinwa luvulekile, ibar iyawiswa phantsi ukuze isiphelo serabha sichukumise umgangatho. Kolu luqwalaselo, ukuqhubela phambili kocango ukuya ekuvaleni kwandisa amandla kwisiphelo serabha, ngaloo ndlela kunyusa amandla omlo ophikisana nentshukumo. Xa ucango luza kuvalwa, isitopu siyakhululwa ngokutyhala ucango luvuleke kancinci, ukhupha istopu kwaye uluvumele ukuba utsibiselwe phezulu. Inguqulelo entsha yokuxhobisa ucango ngesixhobo sokumisa kukuncamathisela umazibuthe emazantsi omnyango kwicala elivula ngaphandle elincamathele komnye umazibuthe okanye izinto zemagnethi eludongeni okanye ihabhu encinci emgangathweni. Imagnethi kufuneka yomelele ngokwaneleyo ukuba ingabamba ubunzima bomnyango, kodwa ibuthathaka ngokwaneleyo ukuba ingaqhagamshelwa ngokulula eludongeni okanye kwihabhu
