Ceiling depository system

A ceiling storage system comprising:

• an overhead transport vehicle having a traveling section traveling on rails arranged at least partly in a grid pattern, and a body section suspended from the traveling section and holding an article on an underside of the rails;
• and
• a storage rack arranged below the rails and storing the article, wherein
• the storage rack has
• a plurality of suspension members extending in an up-down direction, and having a middle portion provided with a rail support and a bottom end provided with a unit support, and
• a shelf unit and a scaffolding unit supported by the unit support of the suspension members, and
• a corner portion of the shelf unit and a corner portion of the scaffolding unit are supported by the unit support;
• wherein the suspension member includes an upper suspension member having a lower end protruding from the rail support and a lower suspension member having an upper end connected to the upper suspension member.

• a corner portion of the shelf unit and a corner portion of the scaffolding unit are supported by the unit support;
• wherein
• the rail includes
• a plurality of first rails extending along a first direction and a plurality of second rails extending along a second direction intersecting the first direction, and
• a plurality of intersection rails arranged with a gap to an end of each first rail and to an end of each second rail, the gap allowing a coupling section coupling the traveling section to the body section to pass through the gap,
• each cell is defined by a pair of the corresponding first rails aligned in the second direction and a pair of the corresponding second rails aligned in the first direction to form a matrix in a grid pattern, and
• the shelf unit and the scaffolding unit each have a shape and a size corresponding to the cells of integer pieces aligned in plan view.
