PROBLEM TO BE SOLVED: To provide a die carrying system by an overhead crane capable of performing a safe overhead crane operation, and constructing a reasonable manufacturing system by eliminating hand-holding, delivery and operations of a maintenance staff, even in a condition, under which a crane operator can not visually recognize objects directly. SOLUTION: Information on a press machine 11 side and information on an overhead crane side C are mutually transmitted between a first date transfer device 1 arranged on a ground and the first data transfer device 1 arranged on the overhead crane side C, the first data transfer device 1 on the overhead crane side C and a control device detecting traveling, traverse and winding positions of the overhead crane by a detection means arranged on the overhead crane side C to control position information of the overhead crane are connected with a data transmission device. Information on the crane operator side and the overhead crane side is wirelessly communicated independently from the information of the first data transfer device 1. COPYRIGHT: (C)2011,JPO&INPIT
