Description
そして、請求項１の発明が採用する構成の特徴は、前記エンジンカバーは、前記エンジンの上方に配置され前記カウンタウエイト側を回動支点とし前記機械室側を自由端として開閉可能なエンジン上部カバーと、該エンジン上部カバーと隣接して前記熱交換器の上方に配置され前記側面板側を回動支点とし前記機械室側を自由端として開閉可能な熱交換器上部カバーとに分割して形成されており、前記エンジン上部カバーと前記熱交換器上部カバーとを閉じたときに前記熱交換器上部カバーの自由端に対して前記エンジン上部カバーの自由端が上側に重なるように配置されることにある。 A feature of the configuration adopted by the invention of claim 1 is that the engine cover is disposed above the engine and can be opened and closed with the counterweight side as a rotation fulcrum and the machine room side as a free end. And a heat exchanger upper cover which is disposed above the heat exchanger adjacent to the engine upper cover and which can be opened and closed with the side plate side as a pivot point and the machine room side as a free end. And when the engine upper cover and the heat exchanger upper cover are closed, the free end of the engine upper cover is arranged so as to overlap the free end of the heat exchanger upper cover. It is in.
請求項２の発明は、前記エンジン上部カバーと前記上面板との間には、前記エンジン上部カバーを閉じた状態で該エンジン上部カバーを前記上面板に対して施錠、解錠可能にロックするロック装置が設けられる構成としたことにある。 According to a second aspect of the present invention, there is provided a lock between the engine upper cover and the upper plate so that the engine upper cover can be locked and unlocked with respect to the upper plate while the engine upper cover is closed. device is that has a structure that is provided.
請求項３の発明は、前記油圧ポンプの上方には、前記エンジンから排出された排気ガスを処理する排気ガス後処理装置を備え、前記排気ガス後処理装置の上方には、前記エンジン上部カバーとは別個に、かつ前記エンジン上部カバーと隣接して前記カウンタウエイト側を回動支点とし前記機械室側を自由端として開閉可能な後処理装置上部カバーが設けられており、前記エンジン上部カバーと前記後処理装置上部カバーとを閉じたときに前記後処理装置上部カバーの自由端に対して前記エンジン上部カバーの自由端が上側に重なるように配置される構成としたことにある。
According to a third aspect of the present invention, an exhaust gas aftertreatment device for treating exhaust gas discharged from the engine is provided above the hydraulic pump, and the engine upper cover is disposed above the exhaust gas aftertreatment device. is separately and the and the adjacent engine top cover said counterweight side openable aftertreatment device upper cover is provided as a free end the machine chamber side and turning fulcrum, the said engine top cover The configuration is such that when the post-processing apparatus upper cover is closed, the free end of the engine upper cover overlaps with the free end of the post-processing apparatus upper cover.
