1. A turnover apparatus comprising: a tower configured to travel on a tower traveling base; a lifter configured to rise and fall along said tower; a target holding portion configured to hold a turnover target; a wheel traveling base which includes a tower following portion and a fixed portion, the tower following portion being configured to be able to travel parallel to said tower; a coupler which couples said tower following portion to said tower; a wheel axle rotatably attached to said target holding portion; a wheel attached to the wheel axle and configured to roll on said wheel traveling base; a wheel axle lock configured to lock said wheel axle such that said wheel does not roll on said wheel traveling base and said wheel axle can rotate with respect to said target holding portion; and a control device, wherein said target holding portion is attached to said lifter via a rotation shaft parallel to said wheel axle, wherein said control device causes said target holding portion to turn over in a first turnover direction by causing said lifter to fall in a state that said wheel axle lock does not lock said wheel axle and said tower is stopped at a position on a front side of said wheel axle, and wherein said control device causes said target holding portion to turn over in a second turnover direction reverse to said first turnover direction by controlling a travel of said tower and rise and fall of said lifter such that said rotation shaft revolves about said wheel axle in a state that said wheel axle is locked by said wheel axle lock and said tower travels toward a back side of said wheel traveling base.
