Due to such a bearing portion, the lifting column 200 is capable of stable sliding movement and minimizes shaft torsion or twisting. Thus, in the case of a boat lift having a plurality of lifting columns 200, the sliding speed of each lifting pillar 200 is different, thereby effectively distributing the external force generated in each lifting pillar 200.
