Provided is a crawler crane in which a rope is wound in a state where the rope is closely arranged on a drum of a hoisting winch regardless of a posture of a boom. A crawler crane includes a main winding winch 19 having a main winding drum 21 and a rope holding device 25 which presses a main winding rope 23 wound around a main winding drum 21 of the main winding winch 19 against the main winding drum 21. The rope holding device 25 is configured to include an oscillating arm 28 whose distal end 28H oscillates in a direction close to or away from the main winding drum 21 with a support shaft 27 as a fulcrum, and a presser roller 29 which is attached to the distal end 28H of the oscillating arm 28 and abuts against the main winding rope 23 wound around the main winding drum 21. A weight member 31, which biases the distal end 28H of the oscillating arm 28 in a direction close to the main winding drum 21 by the gravity with the support shaft 27 as a fulcrum, is provided at a proximal end 28G of the oscillating arm 28.
