To provide a working area management system for a mobile crane capable of easily avoiding interference between cranes at a work site.SOLUTION: A first GNSS terminal 21 is provided on a front end part of a mobile crane 10 and a second GNSS terminal 22 is provided on a rear end part that is opposite to the front end part with respect to a rotation center part of the mobile crane. A position of the mobile crane 10 and a direction of a jib are obtained based on a position measured by the first GNSS terminal 21 and a position measured by the second GNSS terminal 22. A determination area used for determining whether or not the crane is interfered with some other object is set based on the position of the mobile crane and the direction of the jib.SELECTED DRAWING: Figure 1

    【課題】作業現場においてクレーン同士の干渉を容易に回避できる移動式クレーンの作業領域管理システムを提供する。【解決手段】移動式クレーン10の先端部に第1GNSS端末21を設けるとともに、移動式クレーンの旋回中心部に対して先端部とは反対側である後端部に第2GNSS端末22を設ける。第1GNSS端末21によって測定された位置と第2GNSS端末22によって測定された位置とに基づいて、移動式クレーン10の位置とジブの方向を求め、移動式クレーンの位置と前記ジブの方向に基づいて、他の物体との干渉があるか否かの判定に用いる判定エリアを設定する。【選択図】図1
