Hydraulic Passenger Lifts Hydraulic lifts work on the principle: to rise up, a pump pushes oil into the cylinder, pushing the piston up (which pushes up the lift car). To go down, the valve opens and oil is allowed back into the reservoir, pushing it back using the gravitational force of the lift car.
