Bearing capacity examination system of turntable of automobile four-wheel aligner

The utility model discloses a bearing capacity examination system of a turntable of an automobile four-wheel aligner, and aims at solving a problem that the bearing capacity of the turntable of the automobile four-wheel aligner cannot be rapidly and accurately examined. The system comprises a pedestal (1), a long bolt (2), a threaded sleeve (3), a force application leading screw (4), a force measuring sensor (5), and steel ball sets (6). The pedestal (1) of the examination system adopts a circular enclosed structure, so that the borne load counterforce distributed on the pedestal (1) is relatively uniform, and thus rapid and accurate examination of the bearing capacity of the turntable of the automobile four-wheel aligner can be completed.
