Description

本発明の一態様による作業機械は、エンジンと、前記エンジンにより駆動されるポンプと、前記ポンプから吐出される作動流体により駆動されるアクチュエータと、流体を冷却風によって冷却する熱交換器と、冷却風の流れ方向に対し前記熱交換器の上流側に設けられ前記冷却風に混入した粉塵を捕捉するフィルタと、前記エンジンの出力を制御する制御装置と、を備える。前記制御装置は、当該作業機械の作業環境が粉塵の多い環境であるか否かを表す作業環境情報を取得し、取得した前記作業環境情報に基づいて、前記エンジンの出力を制限する。 A work machine according to one aspect of the present invention includes an engine, a pump driven by the engine, an actuator driven by working fluid discharged from the pump, a heat exchanger for cooling the fluid with cooling air, and a cooling A filter provided on the upstream side of the heat exchanger with respect to the flow direction of the air to trap dust mixed in the cooling air, and a control device for controlling the output of the engine. The control device acquires work environment information indicating whether or not the work environment of the work machine is dusty, and limits the output of the engine based on the acquired work environment information.

モード設定部１８２は、情報コントローラ１５０から第１作業環境情報を取得した場合、作業環境情報がオペレータによって設定済みであると判定する。モード設定部１８２は、情報コントローラ１５０から第１作業環境情報が記憶装置１５９に記憶されていないことを表す信号を取得した場合（すなわち、第１作業環境情報を取得することができなかった場合）、作業環境情報がオペレータによって設定されていないと判定する。
When the first work environment information is acquired from the information controller 150, the mode setting unit 182 determines that the work environment information has been set by the operator. When the mode setting unit 182 acquires a signal indicating that the first work environment information is not stored in the storage device 159 from the information controller 150 (that is, when the first work environment information can not be acquired) ), it is determined that the work environment information has not been set by the operator.
