WORK MACHINE WITH SUPERLONG WORK ATTACHMENT
Provided is a work machine capable of decreasing the height of a work attachment in a folded state and suppressing the influence on the operability during demolishing operation. An arm 27 has a surface facing downward when the attachment is in a folded posture, and the surface includes a flat arm contact surface 27b capable of making contact with a mounting surface G, on which a work attachment 24 is mounted; and an attachment surface 27c that extends in the direction away from the mounting surface G. A work device cylinder 32 is attached to the attachment surface 27c so as not to make contact with the mounting surface G. When the attachment is in the attachment folded posture, the arm contact surface 27b is more parallel to a boom upper surface 25b2 than a boom-side sloped surface 25b4 and an arm-side sloped surface 27e or is parallel to the boom upper surface 25b2.
