PROBLEM TO BE SOLVED: To provide a radio communication system for a work machine that can stably communicate between a lower travelling body and an upper rotation body.SOLUTION: A radio transmitter 41 and a radio receiver 42 are respectively arranged in the vicinity of a rotation center of the upper rotation body that rotates relative to the lower travelling body. Thus, the radio transmitter 41 and the radio receiver 42 are arranged in a space surrounded by the lower travelling body, the upper rotation body and a rotation circle, whereby the radio transmitter 41 and the radio receiver 42 can communicate to each other in an environment that is hardly subject to an impact of disturbance.SELECTED DRAWING: Figure 3
【課題】下部走行体と上部旋回体との間で、安定した通信を行うことのできる作業機械の無線通信装置を提供する。【解決手段】無線送信機41及び無線受信機42は、それぞれ下部走行体に対して旋回する上部旋回体の旋回中心の近傍に配置されている。これにより、下部走行体、上部旋回体及び旋回サークルに囲まれた空間に無線送信機41と無線受信機42が配置されることとなり、外乱の影響を受けにくい環境で無線送信機41と無線受信機42との間の通信を行うことができる。【選択図】図3
