PROBLEM TO BE SOLVED: To provide a car body weight support device of a crawler crane which can move a gravity center position of a lower traveling body according to a condition of the crawler crane, thereby enhancing stability.SOLUTION: A lower traveling body of a crawler crane comprises: a pair of left and right crawler frames, which mounts a crawler at the circumference, respectively; a car body 32 which connects both crawler frames and supports an upper structure; and a pair of car body weights 38, 39 provided at both sides of the car body in a front and rear direction. A car body weight support device 50 comprises: a support mechanism 51 for movably supporting at least one of the pair of car body weights; and a drive part 52 for changing a gravity center G position of the lower traveling body by moving the car body weight 38 supported by the support mechanism 51.SELECTED DRAWING: Figure 5

    【課題】クローラクレーンの状況に応じて下部走行体の重心位置を移動させ得るようにし、もって安定性を高め得るクローラクレーンのカーボディウエイト支持装置を提供する。【解決手段】クローラクレーンの下部走行体は、外周に各々クローラを装着する左右一対のクローラフレームと、この両クローラフレーム同士を連結しかつ上部旋回体を支持するカーボディ32と、このカーボディの前後方向両側にそれぞれ設けられた一対のカーボディウエイト38,39とを有する。カーボディウエイト支持装置50は、一対のカーボディウエイトのうちの少なくとも一方を移動可能に支持する支持機構51と、この支持機構51により支持されたカーボディウエイト38を移動させることで下部走行体の重心G位置を前後方向に変更する駆動部52とを備える。【選択図】図5
