To provide an automatic angle control system of a tower crane suspended load and an automatic angle control method which automatically adjust the suspended load lifted by the tower crane to a desired position and angle with a simple method, and improve safety and working efficiency.SOLUTION: A suspended load 7 is suspended from a tower crane 2 via an automatic angle control device 4. An automatic angle control system of a tower crane suspended load acquires continuous three-dimensional position information of the suspended load 7 in real time, which is transmitted from multiple satellite positioning antennae 5 provided on the automatic angle control device 4. The system adjusts the elevation angle of the suspended load based on the three-dimensional position information, adjusts it to the elevation angle of the suspended load mounting position, moves the suspended load above a suspended load mounting position 6 while keeping a suspended load azimuth angle, calculates the suspended load azimuth angle of the suspended load 7, and aligns it with the azimuth angle of the suspended load mounting position at the suspended load mounting position 6.SELECTED DRAWING: Figure 1
【課題】タワークレーンにより揚重された吊荷を簡便な方法により所望の位置及び角度に自動的に調整し、安全性を向上させて作業効率を改善するタワークレーン吊荷の自動角度制御システム及び自動角度制御方法を提供する。【解決手段】タワークレーン2から自動角度制御装置4を介して吊荷7を吊り下げ、自動角度制御装置4に設けられた複数の衛星測位アンテナ5から発信された吊荷7のリアルタイムで連続した三次元位置情報を取得し、この三次元位置情報に基づいて吊荷仰角を調整して吊荷設置位置仰角に合わせ、吊荷方位角を維持しつつ吊荷設置位置6の上部に移動させ、吊荷7の吊荷方位角を算出して吊荷設置位置6での吊荷設置位置方位角に合わせる。【選択図】図1
