PURPOSE:To transmit a signal with high accuracy, by connecting a signal transmission line to a flexible cable which is separated at a bending part of a girder, projected toward the bending direction of the girder and folded in U-shape, with a connector. CONSTITUTION:A signal transmission line 10 transmitting a signal between a driver's room and an electric equipment room of a self-running type working machine consists of two line parts 10A and 10B which are fixed at the side of girders 3A and 3B, and separated at a bending part of the girders. Line connectors 12A and 12B are formed at the upper surface of opposing ends of the line parts, and cable connectors 16A and 16B at both ends of a flexible cable 14 folded in U-shape toward the bending direction of the girder 3 are connected to the connectors. Since a bent back point 14a of the cable 14 is located at a pivot pin 4 of the lines 10A and 10B can always be connected to the cable 14 regardless of the horizontal or bending position of the girder 3 to perform signal transmission. Since the transmission line is fixed to the girder and the bending part is connected to the flexible cable, no damage during the work is caused. |
