To provide an overload protection device that enables an operator of a mobile crane equipped with an overload protection device to easily grasp the rated load and rated working radius, which vary depending on the state of the crane device and the load, and to reduce the working time.SOLUTION: An image information display section 200 includes a basic information display area 210a, a rated value display area 220a, and a turnable area display area 230 and a workable distance display area 240 as workable amount display sections. The rated value display area 220a displays the rated load when a load is not suspended, and displays the rated working radius when a load is suspended.SELECTED DRAWING: Figure 6

    【課題】過負荷防止装置を備える移動式クレーンにおいて、クレーン装置の状態及び負荷によって変化する定格荷重及び定格作業半径を作業者が容易に把握でき、作業時間の短縮を図ることができる過負荷防止装置を提供する。【解決手段】画像情報表示部200は、基本情報表示領域210a及び定格値表示領域220a並びに、作業可能量表示部として旋回可能領域表示領域230及び作業可能距離表示領域240を備えている。定格値表示領域220aは、荷を吊っていないときには定格荷重を表示し、荷を吊っているときには定格作業半径を表示する。【選択図】図6
