Kind Code:
B2
Abstract:
To provide a construction machine in which an exhaust gas post-processing device and an exhaust pipe are compactly provided.SOLUTION: An inflow port 26A of a first exhaust gas post-processing device 25, which is connected to an exhaust gas outflow side of an exhaust pipe 35, is provided on a side opposite to an engine 9 with an axis O1-O1 of the first exhaust gas post-processing device 25 interposed therebetween. A second exhaust gas post-processing device 30 is located on an upper side with respect to the first exhaust gas post-processing device 25 so as to overlap on the first exhaust gas post-processing device 25 in a vertical direction. The exhaust pipe 35 is configured from: a horizontal pipeline 36 which extends along a lengthwise direction of the engine 9 from an exhaust port 10A of the engine 9, and traverses below a cylindrical body 26, which forms the first exhaust gas post-processing device 25, in a direction orthogonal to the axis O1-O1 of the cylindrical body 26; and a bent pipeline 37 which is bent upward from a tip side of the horizontal pipeline 36, and is connected to the inflow port 26A of the first exhaust gas post-processing device 25.SELECTED DRAWING: Figure 4
