A medical emergency portable lift chair assembly adapted to be tiltably wheeled through a doorway and to safely, slowly lift a person off of the ground. It may be powered through a supplied DC battery or through an AC power source. The unit is capable of lifting several hundred pounds up to a safe seating height. It utilizes a high torque linear actuator mounted onto a base frame that raises or lowers a ram coupled to a moveable platform by a pair of redundant pulley arrangements. The base frame sits directly on the floor when the chair assembly is not being wheeled to provide support for the load to be raised. The moveable platform descends to the floor within the framework of the base frame and has a thin graspable chair affixed thereto that resides approximately no more than ¾″ off the floor. A person who has fallen and cant get up may bring themselves in proximity to the chair either frontwards or rearwards, scoot themselves partially on the chair or grasp the chair, and then their weight can be safely raised off of the ground.
