Claims

[Scope of utility model registration request]

At the branching point between one set of fixed girders and three or more sets of fixed girders, there is provided a second set of fixed girders connected to the one set of fixed girders and rotated around an axis on the side of the fixed girder attached to the gate structure. The present invention is characterized in that a second movable girder is provided, which is connected to the tip of the first movable girder by a shaft and is switched to three or more sets of fixed girders by being rotated in the bending direction. Branching device.
