Srew conveyor e masani lava ona faʻaaoga mo le faʻasalalauina o le pauta, maʻa ma tamaʻi vaega o mea ma nisi suavai. O lo matou sikipi masini e lautele faʻaaogaina i le sima palu faʻatasi laʻau, vali tā vali palu, fafaga, vailaʻau alamanuia ma isi pisinisi; e mafai ona faʻaaogaina e feaveaʻi ai le sima, lele lefulefu, minerale pauta, oneone, aisa ma isi mea. Oloa foliga: O le faovilivili masini e faia i le sili ona lelei paipa uʻamea, malosi ma mausali, ma e lelei faʻamaoni. O le faʻalua pitch pitch faʻaititia le tikeri o compression i taimi o mea felauaiga. Na te faʻaaogaina pusa maualuga kia lelei, mamafa-tiute mamanu, lapoa torque ma maualalo leo. O le filifiliga tuu i le lalolagi soofaatasi polo faia faapipiiina ma uli uli faigofie. Faʻatumuina i le maualuga-lelei ogatotonu taofi litaea ma siʻusiʻu bearings, o le aofai o vaega ma faaleoleo vaega e laiti, anagata, faigofie ona tausia, o le vaifagaloa ma fafo e masani, ma o le faapipiiina e vave
