IN WHICH PRINCIPLE HYDRAULIC CRANE WORKS
Hydraulic cranes make use of the incompressibility effect to move enormous amounts of weight up to hundreds of tons.The principle of hydraulics is that many fluids, including water, are incompressible. So once any trapped air is removed, a given volume of the fluid can't be physically squeezed into a smaller space. The molecules of the fluid have already aligned themselves in such a way as to take up the smallest volume they can in that physical state.
