Ukusungulwa komnyango oseduze nomsebenzi wawo
Izivalo zeminyango ye-hydraulic yesimanje (okubizwa ngokuthi izivalo zeminyango) zaqala ngelungelo lobunikazi elibhaliswe yi-United States ekuqaleni kwekhulu lama-20.Ihlukile ekuvaleni kweminyango okujwayelekile ngoba ifinyelela kubhafa ngokucindezela uketshezi olusemnyango eduze..Umnyombo womqondo wokuklama womnyango we-hydraulic oseduze uwukubona ukulawulwa kwenqubo yokuvala umnyango, ukuze izinkomba ezihlukahlukene zokusebenza zenqubo yokuvala umnyango zingalungiswa ngokuvumelana nezidingo zabantu.Ukubaluleka komnyango oseduze akukhona nje ukuvala umnyango ngokuzenzakalelayo, kodwa futhi ukuvikela uhlaka lomnyango kanye nomzimba womnyango (ukuvala okubushelelezi).
Izivalo zeminyango zisetshenziswa kakhulu ezakhiweni zezentengiselwano nezomphakathi, kodwa nasemakhaya.Zinezinto eziningi ezisetshenziswayo, okuyinhloko wukuvumela iminyango ukuthi izivale yodwa, ukunciphisa ukubhebhetheka komlilo kanye nokukhipha umoya endlini.
