PURPOSE:To load and unload a weight material safely further efficiently by using a normal barge, by using while suitably moving plural supporting beds which comprise an intermediate turning part and upper or bottom less frictional face. CONSTITUTION:Supporting beds 2a, 2b comprising a turning unit 4 in the intermediate part and less frictional face 5 in the upper or bottom part are used to support a weight materal L by its both end parts, then the material L is slided from a land side A to the side of a water area S, overhung with one end part of the material L on a barge B and placed on a supporting bed 2c similarly constituted to the above. Further the material L is slided to a side of the barge B while being supported by the beds 2b, 2c on the land A and the barge B, then a supporting bed 2d similar to the above is set on the barge B to a position adjacent to the land side to slide the material L by the beds 2d, 2c on the barge B, thus the material L is moved to a prescribed position finally loaded to the barge B. On the contrary, procedures are reversely taken to the above the unload the material. |
