Abstract
A construction machine comprising a floor plate, an air conditioning unit mounted at the rear of an upper surface of the floor plate, an operator's seat mounted in a central portion of the upper surface of the floor plate, a cab installed on the floor plate from top and provided with a front window and a front air conditioning blowing opening at the front part, and a front duct for connecting between the air conditioning unit and the front air conditioning blowing opening and being divided into at least two detachably connected parts, one out of the divided front ducts being connected to the air conditioning unit, the other being connected to the front air conditioning blowing opening. The front duct for connecting between the air conditioning unit and the front air conditioning blowing opening is divided into at least two parts, and the divided front ducts are respectively connected to the air conditioning unit and the front air conditioning blowing opening, respectively, in advance. Therefore, when the cab is installed on the floor plate from top, the divided front ducts are merely connected whereby the work of duct piping to the front air conditioning blowing opening can be completed. Because of this, the work for installing the cab on the floor plate from top can be simplified greatly, and the time necessary for the installing work can be considerably shortened.
