To ensure operability and safety and reduce consumption power of a remote operation device, in a cargo assistance device.SOLUTION: A cargo assistance device includes a body device 2 and a remote operation device 9 and assists raising/lowering of a cargo. The remote operation device 9 comprises a remote operation device transmission/reception unit 25, operation means 21 to 24, and a remote operation device control unit 20. The body device 2 comprises: a body device transmission/reception unit 14; and a body device control unit 10 that controls raising/lowering of a cargo in a plurality of operation modes. Upon reception of a command signal from the remote operation device 9, the body device control unit 10 commands the body device 2 to shift to each operation mode corresponding to the command signal and transmits to the remote operation device 9 a command to set a communication interval to a predetermined communication interval corresponding to each operation mode. After reception of this, the remote operation device transmission/reception unit 25 transmits to the body device transmission/reception unit 14 a confirmation signal for confirming an establishment of a communication with the body device transmission/reception unit 14 at the predetermined communication interval.SELECTED DRAWING: Figure 3

    【課題】荷役助力装置において、操作性と安全性の確保及び遠隔操作装置の消費電力の低減を課題としている。【解決手段】本体装置2と遠隔操作装置9とで構成されて荷役物の昇降を助力する荷役助力装置であって、遠隔操作装置9は、遠隔操作装置送受信部25と操作手段21〜24と遠隔操作装置制御部20とを備え、本体装置2は、本体装置送受信部14と複数の動作モードにて荷役物の昇降を制御する本体装置制御部10とを備える。本体装置制御部10は、指令信号を遠隔操作装置9から受信すると、指令信号に応じた各動作モードに本体装置2が移行するように指令し、通信間隔を各動作モードに応じた所定の通信間隔にする指令を遠隔操作装置9へ送信し、遠隔操作装置送受信部25はこれを受信した後に所定の通信間隔にて本体装置送受信部14との通信の確立の確認をするための確認信号を本体装置送受信部14へ送信する。【選択図】図3
