Emkhakheni wezinqubo zokugingqa insimbi,imiqulu eshisayo, imiqulu yokusekelayofuthiimiqulu yomsebenzidlala indima ebalulekile ekuqinisekiseni izinga nokusebenza kahle kwenqubo. Lezi zingxenye ezintathu zisebenza ndawonye ukuze zibumbe futhi zicwengisise izinto zensimbi, zizenze zibaluleke kakhulu empumelelweni yawo wonke umsebenzi.

Amaroli ashisayo ayingxenye ebalulekile yenqubo yokugingqa insimbi njengoba anesibopho sokushisisa insimbi emazingeni okushisa adingekayo ekubumbeni nasekubumbeni. Izinga lokushisa lama-roller ashisayo lilawulwa ngokucophelela ukuze kuqinisekiswe i-ductility ephelele yensimbi, okwenza kube lula ukuphatha nokwenza. Ngaphandle kwamarola ashisayo, cishe cishe akunakwenzeka ukufeza ukubunjwa okudingekayo nokubunjwa kwensimbi.

Uma insimbi isishisiswe ezingeni lokushisa elifanele, idlula emigqeni yokusebenza, enesibopho sokubumba impahla. Amaroli okusebenza aklanywa anamaphrofayili athile kanye nokucushwa ukuze kutholwe umkhiqizo wokuphela owufisayo, noma ngabe amashidi ayisicaba, imigoqo emise okwezinsimbi noma amashubhu angenamthungo. Ukunemba kanye nekhwalithi yomqulu wokusebenza kuthinta ngokuqondile ikhwalithi nokunemba komkhiqizo wokugcina.

Nakuba amaroli ashisayo nomsebenzi adlala indima ebalulekile ekubunjweni nasekubunjweni kwensimbi, ama-backup roll ahlinzeka ngokusekela okudingekayo nokuzinza kuyo yonke inqubo. Ama-backup rollers asebenza ngokubambisana nama-roller omsebenzi ukuze anikeze ingcindezi eyengeziwe kanye nokwesekwa ukuqinisekisa ukuthi insimbi yakheka ngendlela efanele. Ngaphandle kwamaroli asekelayo, amaroli omsebenzi ngeke akwazi ukubumba kahle futhi akhe insimbi, okuholela ekushintshaneni nokushiyeka komkhiqizo wokugcina.

Ngamafuphi, ama-hot rolls, ama-backup rolls kanye nama-work rolls yizingxenye ezibalulekile zenqubo yokugoqa insimbi. Ingxenye ngayinye idlala indima eyingqayizivele nebalulekile ekuqinisekiseni izinga, ukusebenza kahle kanye nokunemba kwenqubo. Ngokuqonda ukubaluleka kwalezi zingxenye, abakhiqizi nonjiniyela bangasebenza ukuze bathuthukise ukusebenza kwabo kwensimbi ukuze bathole imiphumela ephakeme.
