PROBLEM TO BE SOLVED: To provide a crane which can inhibit damage and malfunctions of hydraulic equipment and electronic equipment depending on lightning.SOLUTION: A movable crane including a telescopic boom which freely undulates to a swivel base is provided. The crane acquires three dimensional information of a working site in which the crane conveys a conveyance object W, position information of the crane and a three dimensional shape of the crane, position information of structures St, which is set on the working site, having a lightning protection effect, calculates a three dimensional map Wm of the working site based on the three dimensional information of the working site, calculates a current three dimensional shape Cm of the crane based on the three dimensional shape of the crane, attitude information of the crane, and the position information of the crane, calculates a protection range Pa depending on the structures St having the lightning protection effect from the three dimensional map Wm, and displays the protection range Pa depending on the structures St having the lightning protection effect and the current three dimensional shape Cm of the crane in a superimposed manner.SELECTED DRAWING: Figure 4

    【課題】落雷による油圧機器や電子機器の破損や誤動作を抑制することができるクレーンを提供する。【解決手段】旋回台に起伏自在の伸縮ブームが設けられる移動式クレーンであるクレーンにおいて、クレーンが搬送物Wを搬送する作業現場の三次元情報とクレーンの位置情報とクレーンの三次元形状と前記作業現場に設置されている避雷効果のある構造物Stの位置情報とを取得し、前記作業現場の三次元情報に基づいて前記作業現場の三次元マップWmを算出し、クレーンの三次元形状とクレーンの姿勢情報とクレーンの位置情報とに基づいてクレーンの現在の三次元形状Cmを算出し、前記三次元マップWmから避雷効果のある構造物Stによる保護範囲Paを算出し、前記作業現場の三次元マップWmに避雷効果のある構造物Stによる保護範囲Paとクレーンの現在の三次元形状Cmとを重畳的に表示させる。【選択図】図4
