遠隔操作装置。[Claims for Utility Model Registration] A portable operation signal transmitter and a self-propelled crane installed at an appropriate location to receive radio waves emitted from the operation signal transmitter and automatically transmit the operation signals superimposed on the radio waves. A remote control device for a self-propelled crane consisting of an operation signal receiver that outputs to a drive control device of a mobile crane, in particular, the operation signal transmitter transmits radio waves unique to the transmitter in addition to the operation signal. The operation signal receiver is configured to superimpose an identification signal on a received radio wave, and the operation signal receiver includes identification means for identifying whether or not the identification signal is superimposed on a received radio wave. An electric signal corresponding to the operation signal superimposed on the received radio wave is output to the drive control device only when the received radio wave is confirmed, the reception frequency selection being artificially switched by the operation signal transmitter. A switch is provided, and the operation signal transmitter is configured to selectively transmit the first and second transmission radio waves in different frequency bands by operating the frequency selection switch, and the operation signal receiver is configured to select a reception frequency. means, the reception frequency selection means controls selective reception of the first and second emitted radio waves of the operation signal receiver; When it is not possible to confirm that the identification signal is superimposed on the transmitted radio waves of one of the frequency bands selected by A remote control device for a self-propelled crane, characterized in that it is configured to be switched to
