Basic Knowledge Of Hydraulics Pascal’s law Pressure applied at any point upon a confined liquid is transmitted undiminished in all directions (Fig. 1 and 2). Figure 1 pressure force According to Pascal’s law, the oil flow always chooses the line of least resistance in a hydraulic system. This means that when using several hydraulic cylinders, each cylinder lifts at its own speed. When the cylinders have the same capacity, they will first start moving at the point of the lightest load and last at the point of the heaviest load (Fig. 3). A valve block must be added to the lifting system to make...

Basic Knowledge Of Hydraulics Recommended total cylinder capacity In connection with various uncertainties as mentioned below, Holmatro recommends a system with sufficient extra capacity: • The exact weight of the load • The spreading of the load among the cylinders • Possible moving of the load in case of calamities Asymmetric load: Symmetric load: Recommended total cylinder capacity = 1.5 x load Recommended total cylinder capacity = 2 x load Force of a cylinder The force (capacity) generated by a cylinder is equal to the hydraulic pressure multiplied by the effective pressure area of the...
