Abstract
A hydraulic pool lift is disclosed. The lift has enhanced stability due to its adjustable support assembly, and a reinforced piston rod. A load carrying component is rotated 180° from a deck position to a pool position. A curved track on a hydraulically driven piston guides the displacement of the load carrying component. The track is wider in its straight portions. The wider straight portion closely approximates the width of a notch in an end cap through which the track and piston travel. This arrangement affords greater stability in the uppermost position for ease of loading and unloading the lift.
