Uma kukhulunywa ngemishini yezimboni,sekela imiqulu, ukusekela imiqulu, futhiimiqulu yomsebenziidlala indima ebalulekile ekuqinisekiseni ukusebenza kahle nempumelelo kwemishini. Leziimiquluzivame ukusetshenziswa ezinhlotsheni ezahlukene ezifana nokukhiqiza insimbi nensimbi, ukukhiqizwa kwephepha, kanye nezimboni zezimoto. Ukuqonda ukubaluleka kwalawa ma roll nomthelela wawo ekusebenzeni kukonke kwemishini kubalulekile ekugcineni ukukhiqiza kanye nekhwalithi ezinqubweni zokukhiqiza.

Ama-backup rolls, ama-support rolls, nama-work rolls ayingxenye ebalulekile yemishini enesibopho sokuhlinzeka ngokuzinza, ukusekela, kanye nesiqondiso phakathi nenqubo yokukhiqiza. Uhlobo ngalunye lomqulu lufeza injongo ethile nomsebenzi, olunikela ekusebenzeni okuphelele nokusebenza kwemishini.

Amaroli enziwe ikhophi yasenqolobaneni aklanyelwe ukuhlinzeka ngokusekela nokuqondanisa kuma-roll rolls, ukuqinisekisa ukusatshalaliswa okungaguquki kanye nokucindezela phakathi nokucutshungulwa kwezinto.

Ngaphandle kokusekelwa okufanele okuvela kuma-backup rolls, ama-work rolls angase ahlangabezane nokuchezuka kanye nokusatshalaliswa kwengcindezi engalingani, okuholela kukhwalithi ephansi nokukhiqizwa okungaguquki.

I-Support rolls, ngakolunye uhlangothi, inesibopho sokuhlinzeka ngokusekela okwengeziwe kuma-backup rolls nama-work rolls. Lawa maroli abekwe ngendlela efanele ukusiza ekugcineni ukuqondana nokuzinza, ukuvimbela noma yikuphi ukungahleleki okungahle kube khona noma ukuchezuka phakathi nokucutshungulwa kokubalulekile. Amaroli okusekela adlala indima ebalulekile ekunciphiseni ubungozi bokulimala kwamaroli omsebenzi kanye nama-backup rolls, okuthuthukisa impilo ende nokuqina kwemishini.

Ama-work rolls ayizingxenye eziyinhloko ezithintana ngqo nezinto ezicutshungulwayo. Lawa ma-roll anesibopho sokubumba, ukwakheka, kanye nokunciphisa ukujiya kwento, okuyenza ibaluleke kunqubo yokukhiqiza iyonke. Amaroli omsebenzi angaphansi kwengcindezi ephezulu, amazinga okushisa, nezingcindezi zemishini, okugqamisa ukubaluleka kwama-backup rolls athembekile namaroli asekelayo ukuze kuqinisekiswe ukusebenza kwawo okuphelele nokuphila isikhathi eside.

Sengiphetha, ama-backup rolls, ama-support rolls, nama-work rolls yizingxenye ezibalulekile zemishini yezimboni ezithonya kakhulu ukusebenza kahle nokusebenza kwezinqubo zokukhiqiza. Ukusebenza kahle nokuqondanisa kwale miqulu kubalulekile ukuze kuqinisekiswe ukufana, ukuzinza, kanye nekhwalithi emkhiqizweni wokugcina. Ngokuqonda ukubaluleka kwama-backup rolls, ama-support rolls, nama-work rolls, izimboni zingathuthukisa ukusebenza nokuthembeka kwemishini yazo, ekugcineni kuholele ekuthuthukisweni kokukhiqiza nekhwalithi ekukhiqizeni.
