Pascal’s law Pressure applied at any point upon a confined liquid is transmitted undiminished in all directions (fig. 1). 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. 2). A valve block must be added to the lifting system to make sure that the oil flow can be controlled such, that all...

HYDRAULIC CYLINDERS

HOLMATRO CYLINDERS 3-step plan for composing a hydraulic cylinder system Step 1 Select one or more cylinders Considerations: • What is the weight of the load to be lifted? • What is the total recommended cylinder capacity? • With how many cylinders must/can the load be lifted? • What capacity for each cylinder is required then? • What is the required stroke length of the cylinder? • What is the required closed height (overall dimensions) of the cylinder? • How must the plunger return; gravity, spring or hydraulic? • Is lifting in one or more steps possible? See ‘Selection list cylinders’...
