To provide a safety device for a work vehicle which has a simple structure and can reduce manufacturing costs.SOLUTION: A controller 220 of a safety device 200 sets ground reaction force of a plurality of jacks detected by a jack reaction force detector 210 as a reaction force reference value in a state before provisional support of an electric wire on a provisional utility pole, compares the ground reaction force of the plurality of jacks detected by the jack reaction force detector 210 with the reaction force reference value during a temporary support work, and causes an alarm device 230 to activate an alarm when the ground reaction force during the temporary support work falls below the reaction force reference value beyond a certain limit.SELECTED DRAWING: Figure 11

    【課題】構成簡易で製造コストを抑えることが可能な作業車の安全装置を提供する。【解決手段】安全装置200のコントローラ220は、仮電柱に電線を仮支持させる前の状態において、ジャッキ反力検出器210により検出される複数のジャッキの接地反力を反力基準値として設定し、仮支持作業中において、ジャッキ反力検出器210により検出される複数のジャッキの接地反力を反力基準値と比較し、仮支持作業中の接地反力が反力基準値をある限度を越えて下回ったときに、警報装置230による警報作動を行わせるように構成される。【選択図】図11
