To provide a safety device for a high lift work vehicle, which is able to speedily restrict travel of a vehicle body when an overturn prevention plate comes into contact with the ground.SOLUTION: While kept in a spread-out position, an overturn prevention plate 110 is mounted on a plate mounting part 2b of a vehicle body 2 so as to be movable upward by a predetermined amount. The plate mounting part 2b is installed with a limit switch 150A that detects an upward movement of the overturn prevention plate 110. In addition, a travel restricting device is provided for restricting travel of a vehicle body 2 when upward movement of the overturn prevention plate 110 is detected by the limit switch 150A.SELECTED DRAWING: Figure 9
【課題】転倒防止板が地面と当接した際に車体の走行規制を速やかに行うことが可能な高所作業車の安全装置を提供する。【解決手段】転倒防止板110は、展開位置に位置した状態で車体2の板取付部2bに対して上方に所定量だけ移動可能に取り付けられ、板取付部2bには、転倒防止板110が上方に移動したことを検出するリミットスイッチ150Aが設置される。また、リミットスイッチ150Aにより転倒防止板110の上方への移動が検出されたときに、車体2の走行を規制する走行規制装置を備える。【選択図】図9
