PROBLEM TO BE SOLVED: To secure strength of an engine cover, by preventing damage of a hinge caused by rotation of the engine cover, by being provided without impairing detachability of a counterweight, without causing damage of the hinge, when providing a cover connection structure on the near side to the counterweight.SOLUTION: In the present invention, a cover connection structure for rotatably connecting an engine cover 10 in the vertical direction to a turning body 2 side, is provided on the turning body 2 side of a boundary between an engine room 9 and the counterweight 8. A hinge of the cover connection structure includes a first hinge 11 provided in an upstream side near position of a heat exchanger 15 to a flow of cooling air in the rear of the heat exchanger 15 and a second hinge 12 provided in a downstream side part of the heat exchanger 15 to the flow of the cooling air. The cover connection structure comprises a width directional bracket 20 extended in the width direction of the turning body 2 and fixed to the turning body 2 side, and the first hinge 11 and the second hinge 12 are installed in the width directional bracket 20.SELECTED DRAWING: Figure 3 |
