Summary:To provide a work machine for allowing accurate estimation of a load weight in a bucket during the travel of the work machine, and measurement method and system.SOLUTION: To a machine body, running wheels 4 are mounted. A boom 15 is mounted to the machine body. A bucket 14 is mounted to the boom 15. A boom cylinder 18 is mounted to the machine body for driving the boom 15. A controller 50 calculates a weight M2 of loads in the bucket 14 on the basis of boom cylinder force Fboom of the boom cylinder 18 and a ground acceleration ax, ay of a wheel loader 1.SELECTED DRAWING: Figure 1 【課題】作業機械の走行時にバケット内の積荷質量を精度良く推定できる作業機械、計測方法およびシステムを提供する。【解決手段】機械本体には、走行輪４が取り付けられる。ブーム１５は、機械本体に取り付けられる。バケット１４は、ブーム１５に取り付けられる。ブームシリンダ１８は、機械本体に取り付けられ、ブーム１５を駆動する。コントローラ５０は、ブームシリンダ１８のブームシリンダ力Ｆboomとホイールローダ１の対地加速度ａｘ、ａｙとに基づいてバケット１４内の積荷の質量Ｍ２を算出する。【選択図】図１
