Abstract
In a crawler crane of the present invention, a plurality of winches-for winding wire ropes are disposed on a rotating frameof an upper rotating bodyin a row in a plane view. A cabinand a power unitare disposed on the front and rear portions of either a right side or a left side of the rotating frameof the upper rotating body. A working oil tankof the power unitis disposed between the cabinand a driving section-of the power unit and in close proximity to a rear surface of the cabin. The working oil tankis formed in a size which covers the substantially whole area of the rear surface of the cabin. 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.
