PROBLEM TO BE SOLVED: To provide a cargo handling machine which can secure a favorable communication state between a base part and a turning part.SOLUTION: In transmission/reception means arranged between a base part 1 and a turning part 10 of a cargo handling machine, either of a cross angle between reception antennas R1, R2 and a cross angle between transmission antennas S1, S2 is set at 180°, and the other is set at 90°. When one of the reception antennas R1, R2 is separated from one of the transmission antennas S1, S2 by a turn of the turning part 10, one of the reception antennas approaches the other of the transmission antennas S1, S2, a distance between the reception antennas R1, R2 and the transmission antennas S1, S2 is thereby kept at the shortest distance, and a communication failure such as the generation of noise hardly occurs.SELECTED DRAWING: Figure 2
【課題】基部と旋回部との間で良好な通信状態を確保できる荷役機械を提供する。【解決手段】荷役機械の基部1と旋回部10との間に設ける送受信手段であって、受信用アンテナR1、R2の間の交差角と送信用アンテナS1、S2の間の交差角のうち、いずれか一方の交差角が180°、他方の交差角が90°である。旋回部10の旋回によって、受信用アンテナR1、R2のうちの1基が送信用アンテナS1、S2のうちの1基に対し離間するとき、送信用アンテナS1、S2のうちの他の1基に向けて接近するので、受信用アンテナR1、R2と送信用アンテナS1、S2との間の距離が最短に保持されノイズ発生等の通信不良が生じにくくなる。【選択図】図2
