A movable patient lift device that comprises a lower base assembly, an upstanding post assembly mounted on one end of the base assembly, a cantilever boom assembly, which includes a track, mounted on the upper end of the post assembly and extending longitudinally at the distal end beyond the base assembly, and a movable trolley assembly in movable engagement with and supported by the track. The trolley assembly contains a rotatable drum onto which a flexible cable is wound. A patient chair or sling is attached to the other end of the cable and linkage and gearing is provided to enable an operator to rotate the drum thereby raising or lowering the patient, and to longitudinally position the trolley assembly and hence the patient along the track. A cantilever platform is pivotally mounted to the base assembly and extends outwardly therefrom, preferably in the direction opposite that of the boom assembly. When an operator mounts the platform, the operator counterbalances the moment exerted by a patient who is suspended beyond the base assembly.
