Liftit Brand DFPY Series Multistage Hydraulic Cylinder jack.

Long cylinder stroke in confined spaces

Nitrocarburized surface treatment for superior performance in harsh conditions

Hardened surface resists side-loading and cyclic wear

The telescopic / 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 Pascal‟s 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 stepwise. Greater the difference in size between the areas of the cylinder result in greater increase in the force.
