PROBLEM TO BE SOLVED: To provide an apparatus for measuring a load of a working machine capable of measuring a load with a high accuracy by adjusting an attitude of an attachment for holding an object.SOLUTION: An apparatus for measuring a load of a working machine includes: pressure measurement means 34 and 35 for measuring a pressure at a bottom side and a pressure at a rod side of a tilt cylinder 11; inclination angle measurement means 37 for measuring the inclination angle of an attachment or a structural component of the working machine integrally movable with the attachment; and a control mechanism 36 for calculating a load of the object. A control mechanism 36 calculates a shrinking thrust of a rod 13 based on measurement values of the pressure measurement means 34 and 35 in a state that the rod 13 is shrunk by increasing the pressure at the rod 13 of the tilt cylinder 11, calculates an expanding thrust of the rod 13 based on the measurement value of inclination angle measurement means 37, and calculates the load of the object by balancing of the moment in a state that the shrinking thrust and the expanding thrust match with each other.SELECTED DRAWING: Figure 5

    【課題】対象物を保持するアタッチメントの姿勢を調整することにより、精度の高い荷重測定が可能な作業機械の荷重測定装置を提供する。【解決手段】チルト用シリンダ11のボトム側の圧力及びロッド側の圧力を測定する圧力測定手段34、35と、アタッチメント又はアタッチメントと一体に可動する作業機械の構成部品の傾斜角度を測定する傾斜角度測定手段37と、対象物の荷重を演算する制御機構36とを備えており、チルト用シリンダ11のロッド13側の圧力を増大させて、ロッド13が縮んでいる状態において、制御機構36は、圧力測定手段34、35の測定値に基づいてロッド13の縮み推力を算出し、傾斜角度測定手段37の測定値に基づいてロッド13の伸び推力を算出し、縮み推力と伸び推力とが一致した状態において、モーメントの釣り合いにより、対象物の荷重を演算する。【選択図】図5
