LOAD MEASUREMENT DEVICE OF WORK MACHINE
PROBLEM TO BE SOLVED: To provide a load measurement device of a work machine which generates a load confirmed period determination condition according to an operator and work contents and thereby can accurately measure a load of a work object.SOLUTION: A load measurement device of a work machine which includes an attachment and a load calculation section which always calculates an instantaneous load of a work object transported by the attachment during a transport work based on a signal from a position detection section and a thrust detection section includes: a load confirmed condition storage section storing a load confirmed condition for determining a predetermined period during the transportation work; a load confirmation section confirming a load of a work object transported by the attachment based on the instantaneous load for a predetermined period; an external output device outputting the confirmed load of the work object confirmed by the load confirmation section; a storage section storing the instantaneous load calculated by the load calculation section and a history of signals from the position detection section and the thrust detection section; and a load confirmed condition update calculation section which updates and calculates the load confirmation condition based on the history of the signal stored in the storage section.SELECTED DRAWING: Figure 3
【課題】操作者や作業内容に応じた荷重確定期間判定条件を生成することで、精度良く作業対象物の荷重を計測できる作業機械の荷重計測装置を提供する。【解決手段】アタッチメントと、位置検出部と推力検出部からの信号に基づいて運搬作業中にアタッチメントが運搬している作業対象物の瞬時荷重を常時演算する荷重演算部とを備えた作業機械の荷重計測装置において、運搬作業の間の所定期間を判定するための荷重確定条件を記憶する荷重確定条件記憶部と、所定期間の瞬時荷重に基づいてアタッチメントが運搬している作業対象物の荷重を確定する荷重確定部と、荷重確定部で確定した作業対象物の確定荷重を出力する外部出力器と、荷重演算部で演算した瞬時荷重と位置検出部と推力検出部からの信号の履歴を記憶する記憶部と、記憶部に記憶された信号の履歴に基づいて荷重確定条件を更新演算する荷重確定条件更新演算部とを備えた。【選択図】 図３
