Izigxobo ezimnyama zibhekisela kumfanekiso wesigxobo sesibani somgwaqo esingakacutshungulwa kahle. Kuyisakhiwo esimise okwenduku esakhiwe ekuqaleni ngenqubo ethile yokubumba, njengokuphonsa, ukukhipha noma ukugoqa, okunikeza isisekelo sokusika okulandelayo, ukubhoboza, ukwelashwa kwendawo, nezinye izinqubo.
Ngezigxobo ezimnyama zensimbi, ukugoqa kuyindlela evamile. Ngokugoqa ngokuphindaphindiwe i-billet yensimbi emshinini wokugaya, ukuma nobukhulu bayo kuyashintshwa kancane kancane, futhi ekugcineni ukwakheka kwesigxobo sokukhanya komgwaqo kwakhiwa. I-Rolling ingakhiqiza umzimba we-pole onekhwalithi ezinzile namandla aphezulu, futhi ukusebenza kahle kokukhiqiza kuphezulu.
Ukuphakama kwezigxobo ezimnyama kunezincazelo ezihlukahlukene ngokusho kwezimo zokusetshenziswa kwazo. Ngokuvamile, ukuphakama kwezigxobo zokukhanya zasemgwaqweni eduze kwemigwaqo yasemadolobheni cishe kungamamitha angu-5-12. Lolu hlu lobude lungakhanyisa kahle umgwaqo ngenkathi lugwema ukuthikameza izakhiwo ezizungezile nezimoto. Kwezinye izindawo ezivulekile njengezikwele noma izindawo zokupaka ezinkulu, ukuphakama kwezigxobo zokukhanya zasemgwaqweni kungase kufinyelele kumamitha angu-15-20 ukuze kunikeze ububanzi bokukhanya okubanzi.
Sizosika futhi sibhoboze imigodi esigxotsheni esingenalutho ngokwendawo kanye nenani lezibani ezizofakwa. Isibonelo, sika endaweni lapho isibani sifakwe khona phezulu kwesigxobo ukuze uqinisekise ukuthi indawo yokufaka isibani isicaba; bhoboza izimbobo ohlangothini lwesigxobo ukuze ufake izingxenye ezifana nezicabha zokungena kanye namabhokisi okuhlangana kukagesi.
