PROBLEM TO BE SOLVED: To provide a weight floating amount adjustment device of a moving crane which can easily obtain a state that a separation-type weight is floated from the ground surface by a prescribed dimension when hoisting a cargo.SOLUTION: A weight floating amount adjustment device 60 comprises: a detection part 61 which detects a rotation amount of a mast undulation winch; a storage part 65 which stores the rotation amount of the mast undulation winch in a state that a separation-type weight is floated from the ground surface by a prescribed dimension as a reference rotation amount in advance; a calculation part 66 which calculates a difference between the rotation amount which is detected by the detection part 61 and the reference rotation amount when the moving crane is assembled in a work site; and a notification part (display part) 64 which rotates the mast undulation winch with respect to an operator by an amount of the difference which is calculated by the calculation part 66, and promotes the setting of the rotation amount to the reference rotation amount.SELECTED DRAWING: Figure 2

    【課題】荷物の吊り上げ時に分離型ウェイトが地面から所定寸法だけ浮き上がる状態を容易に実現できる移動式クレーンのウェイト浮き量調整装置を提供する。【解決手段】ウェイト浮き量調整装置60は、マスト起伏ウインチの回転量を検知する検知部61と、予め分離型ウェイトが地面から所定寸法浮き上がる状態におけるマスト起伏ウインチの回転量を基準回転量として記憶しておく記憶部65と、移動式クレーンが作業現場で組み立てられたとき検知部61により検知した回転量と基準回転量との差を算出する算出部66と、この算出部66で算出した前記差の分だけオペレータに対しマスト起伏ウインチを回転させ、基準回転量にセットすることを促す報知部(表示部)64とを備える。【選択図】図2
