● Njengoba inohlelo olubanzi olusetshenziswayo , ingasetshenziswa ngokuhambisana nezinhlobo ezihlukahlukene zokuminyanisa udoti kanye nesiteshi sokudlulisa;
● Ukukhipha okuphakanyiswayo okuphindwe kabili kwamasilinda aphakathi nendawo kusebenza ngokwethembeka nangokuzinza ;
● Indlela yokulawula ingasebenza ngokomomotheka nangokuzenzela , ngakho-ke , u - opharetha uyakwazi ukuqedela yonke imisebenzi yokulayisha nokukhipha kukhebhu ;
● Igumbi elivalwe ngokugcwele , elinemicu yenjoloba evalekayo ehlinzekwe ezindaweni ezihlangene phakathi kwekhava yangemuva nebhokisi , libona ukuthuthwa kukadoti okuvalwe ngci ngokugcwele ;
● Ukuvulwa nokuvalwa kwekhava yangemuva kumzimba webhokisi kuqhutshwa ngamanzi , ngesivinini esilungisekayo ;
● Izingxenye ze-Hydraulic ezisetshenziswayo ziwumkhiqizo odumile kazwelonke onekhwalithi ephezulu.
