A power wedge device includes a base, a screw-type cone wedge mounted to the base and including a threaded cone portion that tapers to a pointed tip. A motor is mounted to the base and coupled to the screw-type cone wedge to rotatably drive the threaded cone portion. A counter-rotational member is coupled to the base and is configured to ground the screw-type cone wedge so as to prevent the screw-type cone wedge from spinning the motor and the base.
