構成した機械式連動機構によって連係した作業車におい
て、前記接触センサー１０とそれへの連動部材１１を相
対回動及び摺動自在に取付け、前記接触センサー１０と
連動部材１１の相対回動を阻止する係合部１２を、前記
接触センサー１０と連動部材１１の相対摺動により係脱
自在に設け、前記保合部１２の保合状態を維持する方向
に前記接触センサー１０と連動部材１１を相対摺動すべ
く付勢するスプリング１３を設けである作業車のブーム
上昇制限装置。The contact sensor 10 is swung around an axis 22 that is substantially parallel to the boom vertical swing axis P, depending on whether the boom 3a or the member 9 attached to it hits the boom 3a as it rises.
is provided, and the contact sensor 1 is connected to the control valve ■ of the hydraulic cylinder C that swings the boom 3a up and down.
0 is linked by a mechanical interlocking mechanism configured such that the control valve V is operated from the boom raising operation position to the stop position and against 1,000 human operating force as the sensor 10 swings by the boom 3a. In the working vehicle, the contact sensor 10 and the interlocking member 11 are attached so as to be relatively rotatable and slidable, and the engaging portion 12 that prevents the relative rotation between the contact sensor 10 and the interlocking member 11 is attached to the contact sensor 10 and the interlocking member 11. a spring 13 which is provided to be freely engageable and detachable by relative sliding between the sensor 10 and the interlocking member 11, and which biases the contact sensor 10 and the interlocking member 11 to relative slide in a direction to maintain the engaged state of the retaining portion 12; It is equipped with a boom lifting limiter for work vehicles.
