Using hydraulic systems, heavy bodies can be lifted using low force. The basic concept is that the pressure of all fluid particles is constant at same height.

pressure p=∅*h*g (∅ is density,h is height,g is gravitational constant)

also p=F/A (F is force and A is area of the surface)

if F and A are small on one side to maintain pressure F and A will be more at other side.
