Umshini we-Rolling uluhlobo lwemishini esebenzisa imingcele yomsebenzi ukuze ugobe futhi ulolonge impahla yeshidi. Ingakwazi ukugoqa amapuleti ensimbi emlitheni, ama-arc kanye naku-conical arvices ngaphakathi kwebanga elithile. Kuyinto ebaluleke kakhulu yokusebenza kwemishini. Umgomo osebenzayo womshini wokugibela ipuleti ukuhambisa umqulu womsebenzi ngesenzo samandla angaphandle anjengomfutho we-hydraulic kanye ne-meher arful, ukuze ipuleti ligobe noma ligobeke.
Umshini wokugoqa unezinhlobonhlobo zezicelo, futhi ungasetshenziswa emikhakheni yokukhiqiza imishini efana nemikhumbi, ama-petrochemicals, ama-hydropower, imikhumbi yengcindezi, amapakethe, ama-papermang, ama-motor.
