Umbhobho wentsimbi ochanekileyo luhlobo lwemathiriyeli yombhobho wentsimbi echanekileyo emva komzobo obandayo okanye ukuqengqeleka okushushu.Ngenxa yeenzuzo zokungabikho kwe-oksidi kwiindonga zangaphakathi nangaphandle zombhobho wensimbi ochanekileyo, akukho kuvuza phantsi koxinzelelo oluphezulu, ukuchaneka okuphezulu, ukugqiba okuphezulu, akukho kuguqulwa ngexesha lokugoba okubandayo, akukho kwandiso, ukucanda kwaye akukho kuqhekeka, isetyenziswa kakhulu ukuvelisa i-pneumatic okanye i-hydraulic components, njenge-cylinder yomoya okanye i-oyile cylinder, enokuthi ibe ngumbhobho ongenamthungo okanye umbhobho odityanisiweyo.
