PROBLEM TO BE SOLVED: To provide a cargo handling machine comprising a stem, and a radio communication facility which can assure a good communication state between itself and a slewing part.SOLUTION: A cargo handling machine comprises: a stem 1; a slewing part 10 which is so supported on the stem 1 as to be capable of slewing; a cargo handling part provided on the slewing part 10; stem side transmitting/receiving means located on the stem 1; and slewing part side transmitting/receiving means located on the slewing part 10. At least one of the stem side transmitting/receiving means and the slewing part side transmitting/receiving means comprises a leakage coaxial cable R for transmitting/receiving a radio signal as an antenna, and the leakage coaxial cable R is so provided as to surround a center of slewing of the slewing part 10. By such a configuration, a good communication state between the stem side transmitting/receiving means and the slewing part side transmitting/receiving means can be maintained. Further. Since an arrival range of electric wave is restricted to only a required minimum range, interference to other radio equipment can be prevented, and possibility of entry into a network by other person can be reduced.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無線通信設備が備えられている荷役機械を提供する。【解決手段】荷役機械の基部1と、該基部1に旋回可能に支持された旋回部10と、該旋回部10に設けられた荷役部と、基部1に設置された基部側送受信手段と、旋回部10に設置された旋回部側送受信手段と、を備え、前記基部側送受信手段または旋回部側送受信手段の少なくとも一方が、無線信号を送受信するための漏洩同軸ケーブルRをアンテナとして備え、前記漏洩同軸ケーブルRは、旋回部10の旋回中心を囲むように設けられている荷役機械である。この構成により基部側送受信器と旋回部側送受信器との間の通信状態を良好に維持することができる。また、電波の到達範囲が必要最低限の範囲にのみ限定されるので、他の無線機器への干渉の防止や、他の者からネットワークへの侵入の可能性を少なくできる。【選択図】図2
