To provide a safety control device for a work vehicle capable of instantly stopping a backing operation of a walking work vehicle when a load exceeding a load applied to a handle in normal work is applied to the handle.SOLUTION: A safety control device for a work vehicle includes load detection means 10 attached to a handle 5, and control means 20 to which a signal from the load detection means 10 is input, and which outputs a pushing pressure removal signal. The control means 20 includes a storage unit 21 that stores a threshold, a comparison unit 22 for comparing a detection load detected by the load detection means 10 to the threshold read out from the storage unit 21, and an output unit 23 for outputting the pushing pressure removal signal when it is determined by the comparison unit 22 that the detection load is the threshold or more, and stops a backing operation of a walking work vehicle by drive means 2 by outputting the pushing pressure removal signal.SELECTED DRAWING: Figure 1

    【課題】通常作業時にハンドルに加わる荷重を超える荷重がハンドルに加わった場合に歩行用作業車の後進動作を瞬時に停止できる作業車用安全制御装置を提供すること。【解決手段】本発明の作業車用安全制御装置は、ハンドル5に取り付ける荷重検出手段10と、荷重検出手段10からの信号を入力し、挟圧除去信号を出力する制御手段20とを有し、制御手段20が、閾値を記憶している記憶部21と、荷重検出手段10で検出される検出荷重を記憶部21から読み出した閾値と比較する比較部22と、比較部22によって検出荷重が閾値以上であると判断すると、挟圧除去信号を出力する出力部23とを備え、挟圧除去信号を出力することで、駆動手段2による歩行用作業車の後進動作を停止することを特徴とする。【選択図】図1
