To provide a safety device for a high lift work vehicle capable of restricting and releasing the movement of a work platform without compromising safety.SOLUTION: If a release switch is operated to an operating position before a detected separation distance DK detected by a distance sensor 55 becomes less than a predetermined set distance DS, a safety device restricts the movement of a work platform 40 when the detected separation distance DK becomes less than the set distance DS, and when a specified release operation is performed on the operating lever and release switch after the restriction has been imposed, releases the restriction, allowing the movement of the work platform 40 even in a situation where the detected separation distance DK becomes less than the set distance DS.SELECTED DRAWING: Figure 5

    【課題】安全性を損なうことなく作業台の移動規制および規制解除を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】安全装置は、距離センサ55により検出される検出離隔距離DKが予め定められた設定距離DS以下となる前から解除スイッチが操作位置に操作されていた場合には、検出離隔距離DKが設定距離DS以下となったときに作業台40の移動を規制するとともに、当該規制が行われた後に操作レバーおよび解除スイッチに対し所定の解除操作が行われたときには当該規制を解除して、検出離隔距離DKが設定距離DS以下となった状況においても作業台40の移動を許容する。【選択図】図5
