A portable lifting apparatus for lifting and transferring of patients for use in combination with a sling or the like support. The apparatus is stored in a retracted state by placement of supporting legs and the lifting boom in a folded position. The apparatus can be placed into an operating position in less than two minutes by extension of the support legs and lifting boom which are then locked into position by the use of over-center latches used on leg struts and a boom crutch. Extension is verified by the use of LED indicator lights located on a control panel providing operational sequences from a single location. Separate motors are provided for placement of the legs and boom as well a hoist motor for operating a hoist and a swing motor for angular placement of the boom unit. In a retracted state the apparatus can be stored in a small area such as a closet having a footprint no larger than the size of the base frame. Portability is provided by lockable wheels positioned beneath the frame which can be used in conjunction with hand brakes for braking purposes.
