To provide a hanging load oscillating angle detection device capable of stably detecting information about the oscillating angle of a hanging load rope in longitudinal and horizontal directions, and a crane equipped with the same.SOLUTION: An oscillating angle detection device 60 comprises a first oscillation member 61, a second oscillation member 62, a first oscillation connection part 60T, and a second oscillation connection part 60S. The first oscillation connection part 60T connects the first oscillation member 61 and a boom tip 16Q to each other so that the first and second oscillation members 61, 62 can integrally oscillate about a first rotation center axis CL1. The second oscillation connection part 60S connects the first and second oscillation members 61, 62 to each other so that the second oscillation member 62 can oscillate about a second rotation center axis CL2 relatively to the first oscillation member 61. An oscillating angle sensor 63 is mounted to the second oscillation member 62, and detects the oscillating angle of a main hoist rope 51 in the longitudinal and horizontal directions.SELECTED DRAWING: Figure 3
【課題】吊り荷ロープの前後方向および左右方向における振れ角度に関する情報を安定して検出することが可能な吊り荷ロープの振れ角度検出装置およびこれを備えたクレーンを提供する。【解決手段】振れ角度検出装置60は、第1揺動部材61と、第2揺動部材62と、第1揺動連結部60Tと、第2揺動連結部60Sと、を備える。第1揺動連結部60Tは、第1揺動部材61および第2揺動部材62が第1回転中心軸CL1回りに一体で揺動可能なように、第1揺動部材61とブーム先端部16Qとを互いに連結する。第2揺動連結部60Sは、第2揺動部材62が第1揺動部材61に対して第2回転中心軸CL2回りに相対的に揺動可能なように、第1揺動部材61と第2揺動部材62とを互いに連結する。振れ角センサ63は、第2揺動部材62に装着され前後方向および左右方向の主巻ロープ51の振れ角度を検出する。【選択図】図3
