PROBLEM TO BE SOLVED: To provide a load detection device of a working vehicle which is less affected by hoisting angle and horizontal turning angle of a telescopic boom and can correctly and accurately detect the live load in spite of the acting-point position of the live load in the bucket.SOLUTION: A load detection device 10 has: a link mechanism part 11 with the Roberval structure, including at least two, first and second horizontal link members 11A1, 11A2 arranged in parallel in the vertical direction and supporting a bucket 5 at one end of the first and second horizontal link members 11A1, 11A2; and load detection means 12 to detect the live load of the bucket 5 transmitted through the link mechanism part 11. The load detection device supports the middle part of the first and second horizontal link members 11A1, 11A2 in the link mechanism part 11 oscillatably in the vertical direction.SELECTED DRAWING: Figure 3
【課題】伸縮ブームの起伏角度や水平旋回角度等の影響を受け難く、且つバケットにおける積載荷重の作用点の位置に拘らず、当該積載荷重を精度良く正確に検出できる作業車の荷重検出装置を提供する。【解決手段】荷重検出装置10は、ロバーバル構造からなり、上下方向に平行に配置される少なくとも二本の第一・第二水平リンク部材11A1・11A2を有するとともに、第一・第二水平リンク部材11A1・11A2の一端部においてバケット5を支持するリンク機構部11と、リンク機構部11を介して伝達されるバケット5の積載荷重を検出する荷重検出手段12とを有し、リンク機構部11における第一・第二水平リンク部材11A1・11A2の中途部を、上下方向に各々揺動可能に支持する。【選択図】図3
