Abstract: A fall arresting lift machine has a gantry upon casters, a power source upon the gantry, a drive with a motor upon the gantry in communication with the power source, a controller in communication with the motor and the power source, a vertical strap paying out from the drive motor, a harness upon the strap, and the harness is suitable for wearing by a user. The gantry includes feet, housings, uprights, elbows, braces, and a union. The harness has straps for over both shoulders of the user and a belt and inertial measurement units upon the straps. The drive and controller cooperate to assist a user to sit and to stand, and to detect abrupt acceleration typical of a fall, and arrest the fall. The casters swivel, or alternately select wheels remain in fixed orientation.
