Abstract
A portable, lightweight emergency lifting device for downed persons that is intended for use by paramedics/emergency personnel as well as medical facilities and private owners. The lifting device has a single electric screw extendible ram, with a frictional fail safe lifting system. It has a seat with a ramped front edge in conjunction with an arced support leg configuration that allows the seat to extend to the ground when the device is in its collapsed configuration, to aid in loading the patient. The vertical legs open only to an acute angled position so as to leave the immediate area under the seat open and uncluttered. The frame rolls on a pair of fixed front wheels and a wider pair of rear casters.
