WORK MACHINE, SYSTEM INCLUDING WORK MACHINE, AND CONTROL METHOD OF WORK MACHINE
To prevent objects to be crushed from scattering.SOLUTION: A work machine comprises: a work device crushing an object to be crushed; an electric motor generating a driving force driving the work machine; and a controller. The controller sequentially calculates a load acting on the object to be crushed in a state where the load is acting on the object to be crushed. The controller reduces the driving force generated by the electric motor when a change rate of the load becomes smaller than a threshold value which is a negative number.SELECTED DRAWING: Figure 4
【課題】破砕対象物の飛び散りを抑制する。【解決手段】作業機械は、破砕対象物を破砕する作業機と、作業機を駆動する駆動力を発生する電動モータと、コントローラとを備えている。コントローラは、破砕対象物に荷重が作用した状態で、破砕対象物に作用する荷重を逐次算出する。コントローラは、荷重の変化率が負数である閾値よりも小さくなったとき、電動モータが発生する駆動力を減少させる。【選択図】図４
