Abstract: A lift device for providing unassisted, safe and easy access for disabled or injured persons to a swimming pool or other enclosures of water. The lift device comprises a base frame, a swing arm, an electrical motor for reversibly rotating the swing arm, a fixed housing, a moveable support structure, an electrical motor for moving the moveable support structure, and a carriage. The disabled or injured individual can activate the lift device by a movable pushbutton station, while seated in the carriage. Once the lift device is activated, the electrical motor for reversibly rotating the swing arm rotates the swing arm, roller support structure and translating support structure over the pool or other enclosure of water. At this point, the disabled or injured individual can activate the electrical motor for translating the translating support structure in order to lower the carriage into the pool.
