To provide a construction machine capable of preventing heat and noise generated by an engine and hydraulic equipment from leaking out outside and improving the work environment of an operator and a worker around the machine.
In this construction machine, a revolving frame 6 includes a shielding cover 26 being positioned between the equipment mounted in the machine such as the engine 7, a control valve 13 or the like and a tilt floor 16 and covering these equipment mounted in the machine to insulate heat and sound. In this case, since the shielding cover 26 being provided separately from the tilt floor 16 does not require the formation of a clearance for allowing the tilting operation, the shielding cover 26 can cover the engine 7, the control valve 13 or the like on the revolving frame 6 without forming a clearance to prevent heat and noise from leaking to the outside. Further, the shielding cover 26 has openings for work 27A, 27B, 29F, 29H to allow the worker to perform periodic maintenance work through these openings for work 27A, 27B, 29F, 29H.
