The present invention includes: left and right bodies having a square shape on which a worker is able to get, having a side liked through a hinge shaft, and having a semicircular groove covering the outer surface of a loading arm; a separation preventing unit placed on the left and right bodies, facing a link combination part of the left and right bodies, and preventing rotation around the link while covering the loading arm through the left and right bodies; and a fall preventing device preventing the loading arm from falling along the outer surface while the left and right bodies cover the loading arm. Therefore, since a square frame to cover the outer surface of the loading arm of the loading arm structure on the vessel body is prepared, a worker is able to stably perform maintenance work on a proper position, and especially, the square frame is easily separated and combined and is prevented from falling along the outer surface of the loading arm in order to more stably and quickly perform repair work. |
