A vehicle lift includes a hydraulic cylinder having a component that rotates as the cylinder lengthens and shortens. A sensor measures the rotation or rotational position of the rotating component, and the sensor's output is used by a controller to control the vehicle lift. In some embodiments, the vehicle lift includes a scissor or parallelogram mechanism, while others are column lifts. In some embodiments, the controller uses the sensor's output to manage the limits of travel of the vehicle lift, and in others, the controller uses it to coordinate lift operations with other lifts.
