摘要： The present invention provides a compact hydraulic excavator comprising: a lower traveling body, an upper rotating body installed rotatably on the lower traveling body, an apparatus cover risen from a floor plate of the upper rotating body, an operator's seat arranged on the apparatus cover, an operator's seat fixing member for fixing the operator's seat, a cabin provided astride of the apparatus cover and the floor plate, the apparatus cover having the side and the back surface exposed to outside so that the cabin serves as a part of the side and the back surface, and a mounting plate projected substantially in a horizontal direction from the operator's seat fixing member, the side wall of the cabin being risen from the outer circumferential edge of the mounting plate. According to the present invention, it is possible to install a larger cabin than the size of an existing compact hydraulic excavator without newly re-designing an apparatus cover.
