How does a hydraulic lift work, and what are the two variations of hydraulic lift?
The hydraulic lift only drives in the upwards direction. Hydraulic oil from a reservoir is forced into the system by a pump to raise the lift car. For downwards travel the hydraulic oil is pushed back into the reservoir by the weight of the car
