歩み装置。 A storage section is formed at the rear edge of the loading platform in the form of a step that is lower than the loading surface by the thickness of the footboard and has a depth equal to the width of the footboard. The rear half folded in half from the branch is swung by a cylinder and reversed to the tip of the front half to provide left and right footboards that can be lowered freely, with the front ends of the footboards attached to spindles near the left and right ends of the storage surface. In preparation for a state in which the shaft is pivotably mounted and both shaft supports face each other, guide grooves are installed on the left and right sides of the retracted part in a concentric circle with the support shaft from the side position beside the support shaft pivot part in the retracted step board. A pin shaft is formed in a 1/4 circle shape, and an upright pin shaft is attached to the tips of the left and right cylinder rods under the storage section through the guide groove to the side portion eccentric from the pivot pivot point in the front half of the stepboard on the storage section. Automatic walking device for freight cars that pivots in position.
