PROBLEM TO BE SOLVED: To enhance safety property of cargo handling operation by informing a neighbor worker of approach to a fork lift 2 accurately even in a cargo handling field with many shields.SOLUTION: A safety device for the fork lift provides a security lamp 3 in a rear upward direction of a fork lift 2. A plurality of light sources are arranged in the security lamp 3 and a warning image picture 5 is depicted on a rear road surface of the fork lift 2 by spot light 6 which each light sources irradiates. An ECU 7 controls blink period of the light sources on the basis of a signal of a vehicle speed sensor 8 so that the warning image picture 5 changes during travel of the fork lift 2 and simultaneously controls an irradiation direction of the security lamp 3 on the basis of a signal of a steering angle sensor 9 and changes light distribution pattern 10 of the security lamp 3 accompanied by movement of the fork lift 2 dynamically.SELECTED DRAWING: Figure 1
【課題】遮蔽物の多い荷役現場であっても、フォークリフト2の接近を周辺の作業者に的確に知らせ、荷役作業の安全性を高める。【解決手段】フォークリフト2の後部上方に保安ランプ3を設ける。保安ランプ3に複数の光源を配列し、各光源が照射したスポット光6でフォークリフト2の後方路面上に警告画像5を描画する。フォークリフト2の走行中に、警告画像5が変化するように、ECU7は、車速センサ8の信号に基づいて光源の点滅周期を制御するとともに、操舵角センサ9の信号に基づいて保安ランプ3の照射方向を制御し、フォークリフト2の移動に伴って保安ランプ3の配光パターン10を動的に変化させる。【選択図】図1
