PROBLEM TO BE SOLVED: To wind up a rope in an aligned state on the winding winch drum regardless of the boom attitude.SOLUTION: A crawler crane comprises a main winding winch 19 with a main winding drum 21 and a rope pressing device 25 to press a main winding rope 23 wound around the main winding drum 21 of the main winding winch 19 on the main winding drum 21. The rope pressing device 25 is configured to include a swing arm 28 the tip of which swings in the direction approaching to or separating from the main winding drum 21 around a supporting shaft 27 as a fulcrum and a pressing roller 29 to be installed at the tip of the swing arm 28 and to abut against the main winding rope 23 wound around the main winding drum 21. A weight member 31 is installed at the base end of the swing arm 28 to energize the tip of the swing arm 28 in the approaching direction to the main winding drum 21 by gravity with the supporting shaft 27 as fulcrum.SELECTED DRAWING: Figure 5

    【課題】ブームの姿勢に関わらず、巻上ウインチのドラムに対してロープを整列した状態で巻取る。【解決手段】主巻ドラム21を有する主巻ウインチ19と、主巻ウインチ19の主巻ドラム21に巻回された主巻ロープ23を主巻ドラム21に押付けるロープ押え装置25とを備える。ロープ押え装置25は、先端が支持軸27を支点として主巻ドラム21に接近または離間する方向に揺動する揺動アーム28と、揺動アーム28の先端に取付けられ、主巻ドラム21に巻回された主巻ロープ23に当接する押えローラ29とを含んで構成される。揺動アーム28の基端には、支持軸27を支点として、重力により揺動アーム28の先端を主巻ドラム21に接近する方向に付勢するウエイト部材31が設けられている。【選択図】図5
