Hardened surface resists side-loading and cyclic wear
The telescopic or Multistage hydraulic jack works as a liquid column which is very useful in achieving desire height within the limited cross section area. The working of the telescopic jack is based on Pascals law which states that The pressure in a closed container is same at all points. If there are four cylinder connected applying force on the smaller cylinder will result in the same amount of pressure in the larger cylinder which has greater area, the resulting force will be greater i.e., an increase in area leads to increase in the force step wise. Greater the difference in size between the areas of the cylinder result in greater increase in the force.
