To provide a boom collision prevention device for a cargo handling machine capable of preventing a collision regardless of the shape of a collision object.SOLUTION: A boom collision prevention device for a cargo handling machine has a 3D sensor 90, a controller 91, and a display 92. The 3D sensor 90 is mounted on a boom 60 of a container crane 10 and emits a pulsed laser beam to a collision object 80 to detect the scattered light reflected from the object. The controller 91 determines the distance from the 3D sensor 90 to the collision object 80 based on the changing measurement data of the scattered light detected by the 3D sensor 90, and calculates the relative travel speed between the collision object 80 and the boom 60 using the distance and time. The display unit 92 displays the collision object 80 and the boom 60 so that their relative positions are recognized based on the travel speed calculated by the controller 91.SELECTED DRAWING: Figure 1

    【課題】衝突対象物がどのような形状であっても衝突を未然に防ぐことができる荷役機械のブーム衝突防止装置を提供する。【解決手段】3Dセンサ90と、制御器91と、表示器92とを備え、3Dセンサ90は、コンテナクレーン10のブーム60に取り付けられ、パルス状に発光するレーザ光を衝突対象物80に照射して反射した散乱光を検出し、制御器91は、3Dセンサ90で検出される散乱光の時々刻々変化する計測データに基づき、3Dセンサ90から衝突対象物80までの距離を求め、距離と時間とにより衝突対象物80とブーム60との相対的な移動速度を演算し、表示器92は、制御器91で演算された移動速度に基づき、衝突対象物80とブーム60とをその相対位置関係が認識されるよう表示する。【選択図】図1
