ABSTRACT:
In a crawler crane of the present invention, a plurality of winches11-14for winding wire ropes are disposed on a rotating frame6of an upper rotating body3in a row in a plane view. A cabin17and a power unit18are disposed on the front and rear portions of either a right side or a left side of the rotating frame6of the upper rotating body3. A working oil tank36of the power unit18is disposed between the cabin17and a driving section31-34of the power unit and in close proximity to a rear surface of the cabin17. The working oil tank36is formed in a size which covers the substantially whole area of the rear surface of the cabin17. In the crawler crane of the present invention, it is possible to take an anti-sound measure for the cabin to a satisfactory extent without causing cost increase. In the crawler crane of the present invention, moreover, it is possible to improve the transportability because the width of the upper rotating body can be shortened.
