Ukuthathwa kwemizi-mveliso kwenziwe ngoomatshini bokushicilela okanye iindebe zenziwa ngumoya oxinzelelweyo, umbane, i-hydraulics okanye steam. Ezi hamers zinokuba zibuyise iintsimbi kumawakawaka eepawundi. I-hamers yamandla amancinci, i-500 lb (230 kg) okanye ngaphantsi kokubuyisa ubunzima, kwaye oomatshini bokushicilela be-hyddddraulic baxhaphakile kubugcisa bobugcisa. Ezinye iindonga ze-steam zihlala zisetyenziswa, kodwa zaphela ngokufumaneka kwenye, imithombo efanelekileyo, yombane.
