A liner hanger apparatus, comprising: a body including an inner bore, an outer surface, a wall between the inner bore and the outer surface and a tapered segment on an outer surface of the body; a plurality of slips disposed on the outer surface of the body, the plurality of slips being actuatable to move from an unset position adjacent a small diameter end of the tapered segment to a set position on the tapered segment of the body to increase a diameter of the apparatus; a locking mechanism to hold the plurality of slips in the unset position; and an actuation system to unlock the locking mechanism, wherein the actuation system involves mechanisms of operation other than hydraulic fluid communication through the wall, such that the body is thereby free of hydraulic ports extending through the wall.
