The modern power hydraulic actuators which have found the broadest application in various areas of equipment, often perform so responsible functions that safety of machines operation depends on their reliability. The review of existing hydraulic systems of load-lifting devices showed that practically all of them have the same schematic hydraulic diagram which main disadvantage is the low reliability that quite often leads to emergence situations even including humans death. This paper develops recommendations about the increase of reliability of such devices due to reservation of units and knots of hydraulic systems.
