Filmy body null for rainy weather cargo handling equipment

摘要

PURPOSE: To make a sea-side overhung member and a land-side structure lighter by integrating the front and side faces of an elevatable membranous material which is installed on a building overhung from a quaywall to the sea side and mounting both ends of the frame of the membranous material to a sea-side column in an elevatable manner. ;CONSTITUTION: An elevatable membranous material 8 is formed with the front and side faces integrated in an elevation range from a height over a mast to the height of a relatively tall on-board structure. Both ends of the frame 9 of the membranous material 8 is mounted to a sea-side column 15 in an elevatable manner. Wind load on the membranous material 8 during usual cargo handling work is transmitted directly to the sea-side column 15 through the frame, with almost no effect on a sea-side overhung member. When the membranous material 8 is hit by too severe wavy wind to do cargo handling work, it is elevated up to the upper limit and stored in a case 5 in a building 4 to eliminate wind load thereon and prevent the transmission to the sea-side overhung member. As a result, the relatively light sea-side overhung member as well as a relatively light supporting land-side structure are only required.;COPYRIGHT: (C)1994,JPO&Japio
