Description of the Related Art For example, a parent-child truck for moving a steel sheet coil or the like in a factory is used when transferring a steel sheet coil from one line in a factory to another line or from a factory to an adjacent warehouse. There is. Since it is difficult to lay a curved rail with a large radius of curvature in a factory like a general railroad, conventionally, as shown in the plan view of FIG. 2b and 2c are provided, and from the parent carriage 1a on the traveling rail 2a to the traveling rail 2
When passing the steel plate coil to the parent carriage 1b or 1c of b or 2c, the child carriage 3 mounted on the parent carriage 1a uses the coil mount on the swivel base 5 provided at the intersection of the rail 4 for the child carriage 3 as a relay point. The steel plate coil is passed from the child car 3 to the parent car 1b or 1c. The child carriage rails 4 arranged at other locations are rails leading to the processing line or the coil storage area.

By this action, the flangeless wheels are guided along the rails and traveled by the drive of a travel motor provided on at least one single-wheel bogie. When the parent truck travels on the curved rail section, the axis passing through the symmetrical single-wheel bogie on the truck deviates from the radius of curvature of the curve rail, and the space on the left and right rails corresponding to the wheels of the single-wheel bogie is substantially. When it spreads out, either the left or right single wheel bogie on the parent bogie will automatically slide in the bogie axial direction by the action of the sliding mechanism on the bogie, and the single wheel bogie will automatically change when the rail spacing changes substantially. It is possible to stably follow a curved rail having a small radius of curvature by following the target.
