Hydraulic drives SDTB «Zaporozhgidrostal» elaborated are working without failures at many projects of ex-URSS and in foreign countries.
Hydraulic drive is the most progressive type of stationary mechanism and it is used widely to operate gates. A hydraulic drive is a compound device, it consists of one or several hydraulic cylinders interconnected with piping, a hydraulic board and an oil pumping unit.
Depending on purpose, operational conditions and requirements, one or several oil pumping units are used in hydraulic drive. Hydraulic cylinders can be immersed in water completely or partially. Hydraulic cylinder can be connected to the gate in one of the following manners:
- with bars (booster bars as well);
- with plate chains;
- with block-linkage mechanism;
- in combined way.
Oil pumping unit, electrical equipment, hydraulic boards of hydraulic drive must be located indoors.
Ability to develop high traction and booster forces with manipulation control is the advantage of hydraulic drives when compared to other mechanisms.
