To detect obstacles around a light emitter/receiver.SOLUTION: An obstacle detection device includes a second control unit. The second control unit has a detection area storage unit that stores in advance a plurality of obstacle detection areas for detecting obstacles around a light emitter/receiver 19, and an obstacle detection unit that detects surrounding obstacles in the horizontal direction of the light emitter/receiver by analyzing reflected light in any of the obstacle detection areas. The plurality of obstacle detection areas includes an obstacle detection area EB of a pattern B that does not include the area in the direction of a lift member in the horizontal direction. The obstacle detection unit switches the obstacle detection area based on the height of the lift member to prevent erroneous detection of the lift member or a load as an obstacle.SELECTED DRAWING: Figure 8
【課題】投受光器の周囲の障害物を検出する。【解決手段】障害物検出装置は、第2制御部を備えている。第2制御部は、投受光器19の周囲の障害物を検出するための複数の障害物検出エリアを予め記憶している検出エリア記憶部と、いずれかの障害物検出エリアにおいて、反射光を解析して投受光器の水平方向における周囲の障害物を検出する障害物検出部と、を有する。複数の障害物検出エリアには、水平方向におけるリフト部材方向のエリアを含まないBパターンの障害物検出エリアEBが含まれている。障害物検出部は、リフト部材の高さに基づいて、障害物検出エリアを切り替えてリフト部材または荷を障害物として誤検出することを防止する。【選択図】図8
