HOLDING WEIGHT MEASURING METHOD AND DEVICE FOR WORKING MACHINE
To provide a holding weight measuring method and a device for a working machine to measure holding weight corresponding to weight of an object to be held with a tip attachment in a simple configuration and with accuracy.SOLUTION: A measuring method in accordance with the present invention includes: a pressure releasing step for releasing pressure of hydraulic oil in a holding side hydraulic chamber 36 of an attachment cylinder 28 making a tip attachment rotate around an attachment rotating axis; a detection step for detecting the pressure of hydraulic oil in the holding side hydraulic chamber 36 of the attachment cylinder 28 at a time when a measuring condition is satisfied after the pressure releasing motion is started and a moment specific physical amount as a detected holding pressure and a detected physical amount, respectively; and a holding weight calculation step for calculating holding weight based on the detected holding pressure and the detected physical amount.SELECTED DRAWING: Figure 3
【課題】先端アタッチメントにより保持される被保持物の重量に対応する保持重量を簡素な構成で精度よく測定するための方法及び装置を提供する。【解決手段】提供される方法は、先端アタッチメントをアタッチメント回動軸回りに回動させるアタッチメントシリンダ２８の保持側油圧室３６の作動油の圧力を抜く圧力抜き動作を行うことと、圧力抜き動作が開始されてから測定条件が満たされた時点でのアタッチメントシリンダ２８の保持側油圧室３６の作動油の圧力及びモーメント特定物理量をそれぞれ検出保持圧及び検出物理量として検出することと、検出保持圧及び検出物理量に基づいて保持重量を算定する保持重量算定ステップと、を含む。【選択図】図３
