Summary:To provide a device that controls operation of a crane so as to improve efficiency of slinging work performed by a worker while ensuring safety of the worker.SOLUTION: In a situation where no designated signal is detected by a signal detector 202, operations for displacing a hook of the crane is allowed. On the other hand, in a situation where the designated signal is detected by the signal detector 202, operation for displacing the hook 17 of the crane 10 may be restricted on a condition that a terminal device 40 is present in a first designated region. This situation corresponds to a situation where a distance between the terminal device 40 and a designated location of the crane 10 is so small that the designated signal transmitted from the terminal device 40 is detected by the signal detector 202 (or the terminal device 40 is present in a first designated region).SELECTED DRAWING: Figure 1 【課題】作業者の安全性を確保しながら当該作業者による玉掛け作業効率の向上を図りうるようにクレーンの動作を制御する装置を提供する。【解決手段】信号検出器202により指定信号が検出されない状況では、クレーンのフックを変位させるための動作が許容される。その一方、信号検出器202により指定信号が検出される状況では、端末装置40が第1指定領域に存在することを要件として、クレーン10のフック17を変位させるための動作が制限されうる。この状況は、端末装置40から送信された指定信号が、信号検出器202により検出される程度に端末装置40とクレーン10の指定箇所との間隔が小さい状況(または端末装置40が第1指定領域に存在している状況)に相当する。【選択図】図1
