REMOTE CONTROL DEVICE AND OPERATION DEVICE

摘要

PROBLEM TO BE SOLVED: To obtain a remote control device stopping the operation of the operation means of a boom surely and not requiring the ON state of the electric source of an upper operation device. SOLUTION: An upper operation device 16 sends an operation signal for controlling the operation of an operation device 17 and an upper CPU 32 sends a luminous control signal predetermined responding to the operation signal from the upper operation device 16. A luminosity 33 emits a light signal controlled based on the liminous control signal sent from the upper CPU 32 and also emits the light signal continuously when the stop operation of a stop switch 35 is carried out. A light receiver 42 received the light signal from the luminosity 33 sends the operation control signal to a lower CPU 43 for carrying out the operation control of the operation device 17. A continuous luminous detection device 44 and operation stop device 45 stop the operation device 17, regardless of the operation control of the operation device 17 by the lower CPU 43 at the receiving time of the light signal emitted continuously.
