The invention discloses a unilateral force bearing non-avoidance stereo parking garage, which comprises a ground rail. A movable base is arranged on the ground rail, and the front end of the movable base is connected with a vertical supporting column through a rotary mechanism, and a sliding sleeve is arranged outside the vertical supporting column in a sleeving mode; and the side end of the sliding sleeve is connected with a parking plate, and a hydraulic oil cylinder is mounted at the top end of the vertical supporting column and connected with the sliding sleeve through a lifting chain. Theinvention discloses a bilateral force bearing non-avoidance stereo parking garage, which comprises a lower side vehicle supporting plate. Straight rails are arranged on the two sides of the lower side vehicle supporting plate correspondingly, and a first movable seat and a second movable seat are arranged on the straight rails correspondingly; the tops of the first movable seat and the second movable seat are connected with rotation supporting frames through rotation driving structures correspondingly; and top driving tables are arranged at the tops of the rotation supporting frames correspondingly. The non-avoidance stereo parking garage has two supporting modes, the parking plate can be quickly ascended, descended and rotated through the supporting mode of unilateral force bearing, stability of the parking plate can be improved through the supporting mode of bilateral force bearing, and thus the potential safety hazard is eliminated advantageously.
