Abstract

PURPOSE:To decrease the number of electric wires and reduce their total length, by combining a conductor and an insulator with each other in a trolley duct. CONSTITUTION:The trolley duct 30 is provided to transmit and receive signals with dolly signal transmission trolley ducts Tij (i=1-M, j=1-N) in a rack through a control panel 5 provided on a crane. One end of the trolley duct 30 is attached to the crane. A trolley shoe 31 is moved in the trolley duct 30 in response to the motion of the crane. The trolley shoe 31 is coupled to the control panel 5 through a signal line 32 and signal lines W1', W2',..., WM'. The conductor and the insulator are combined with each other in the trolley duct 30 so that the trolley shoe 31 can be electrically connected only through its part in contact with the conductor 34.
