<p>PROBLEM TO BE SOLVED: To provide a target container replacing carriage installed at a correct position on a rail by using a rail having a simple structure without forming a deep groove or a special rail on a floor and by absorbing a large error at a suspending position based on a remote operation by a crane. SOLUTION: This target container replacing carriage is provided with one or more pairs of side rollers 45 so as to be able to change the distance from the bottom face of the carriage 32 and is so structured that while keeping the vertical attitudes of the side roller rotation axes, the axis-to-axis distance is horizontally changed, and a vertical line erected at the middle point of a line connecting both the rotation axes is fixed with respect to the carriage, and the distance between the rotation axes are reduced when the distance from the bottom face is increased, and increased until both the side rollers 45 hit against the rail 6 surfaces when the distance from the bottom face is decreased. In addition, the carriage is so structured that each side roller 45 is provided with a leg-straddling roller 47 rotating in the transverse direction of the carriage 32 on its undersurface, and the leg-straddling rollers 47 are lifted from the floor at positions both the side rollers 45 abut on the guide rail 6 surfaces.</p> |
