PROBLEM TO BE SOLVED: To provide a crane which illuminates and outputs a warning to a necessary range, and suppresses impact to neighborhood.SOLUTION: A tower crane 1 is provided on a jib 3 on an upper end of a columnar support 2, and plural luminaires 5 and a speaker 7 are attached to the jib 3. The luminaires 5 and the speaker 7 oscillate by self weight, following to change of inclination of the jib 3 in a vertical plane, and the luminaires and speaker are directed downward always. The luminaires 5 are configured so that, by using a wire, orientations of the luminaires in a cross direction and a lateral direction can be adjusted. The orientations of the plural luminaires 5 can be adjusted simultaneously.SELECTED DRAWING: Figure 1
【課題】必要な範囲に照明や警報を行い、近隣への影響を低減できるクレーン等を提供する。【解決手段】タワークレーン1は支柱2の上端にジブ3に設けたものであり、複数の照明装置5およびスピーカ7がジブ3に装着される。これらの照明装置5およびスピーカ7は、鉛直面内におけるジブ3の傾きの変化に伴って自重により揺動し、常に下を向くようになっている。照明装置5は、ワイヤ等を用いることにより前後、左右の向きを調整可能とすることもできる。また複数の照明装置5の向きを一斉に調整可能とすることもできる。【選択図】図1
