PROBLEM TO BE SOLVED: To increase workability when performing maintenance on installed equipment.SOLUTION: An inspection opening 17 is provided between a left side cover 15 and a right side cover 16 for performing a maintenance work on an installed equipment such as an engine 8 housed in a prime mover chamber 11, and a prime mover cover 18 for covering the inspection opening 17 so as to be openable and closable is provided. The prime mover cover 18 is moved in parallel upward and downward between a closed position where a cover opening and closing mechanism 21 closes the inspection opening 17 and an opening position where the inspection opening 17 is opened. On the other hand, a support bracket 32 for supporting the prime mover cover 18 via the cover opening and closing mechanism 21 is disposed on the rear side of a support member 9 provided on a revolving frame 6. The support bracket 32 is supported on a bracket attachment member 30 provided on the rear side of the support member 9 so as to be rotatable in the left and right directions using a hinge mechanism 33.SELECTED DRAWING: Figure 4

    【課題】搭載機器に対するメンテナンスを行うときの作業性を高める。【解決手段】 左側面カバー15と右側面カバー16との間に、原動機室11内に収容されたエンジン8等の搭載機器に対するメンテナンス作業を行うための点検用開口17が設けられ、この点検用開口17を開閉可能に覆う原動機カバー18を備える。原動機カバー18は、カバー開閉機構21によって点検用開口17を閉塞する閉位置と点検用開口17を開放する開位置との間で上,下方向に平行移動する。一方、旋回フレーム6に設けられたサポート部材9の後側には、カバー開閉機構21を介して原動機カバー18を支持する支持ブラケット32が配置され、この支持ブラケット32は、サポート部材9の後側に設けられたブラケット取付部材30に、ヒンジ機構33を用いて左,右方向に回動可能に支持されている。【選択図】 図4
