To provide a collision prevention device capable of further reliably suppressing collision of a cargo.SOLUTION: A collision prevention device for a cargo includes a sensor for detecting an obstacle present in a lowering direction of a support mechanism and detecting a distance between a cargo supported by the support mechanism and the obstacle and a control unit, which sequentially acquires information about the distance from the sensor, sequentially acquires information about the lowering speed of the support mechanism from a main device, calculates a first moving distance until the support mechanism reaches the preset minimum speed based on the information about the lowering speed and the deceleration of the preset lowering speed, and outputs a deceleration command for reducing the lowering speed to the main device based on the first moving distance and the distance. The control unit sequentially determines whether the lowering speed is in an accelerating state or a constant speed state based on the sequentially obtained lowering speed.SELECTED DRAWING: Figure 2

    【課題】貨物の衝突をより確実に抑制できる衝突防止装置を提供する。【解決手段】実施形態は、支持機構の巻下げの方向に存在する障害物を検出し、前記支持機構に指示された貨物から前記障害物までの距離を検出するセンサと、前記センサから前記距離の情報を逐次取得し、前記主幹装置から前記支持機構の巻下速度の情報を逐次取得し、前記巻下速度の情報及びあらかじめ設定された巻下速度の減速度にもとづいて、前記支持機構があらかじめ設定された最低速度に達するまでの第1移動距離を算出し、前記第1移動距離及び前記距離にもとづいて、前記巻下速度を減速させる減速指令を前記主幹装置に出力する制御部と、を備える。前記制御部は、逐次取得する前記巻下速度にもとづいて、前記巻下速度が加速状態にあるか、定速状態にあるかを逐次判定する。【選択図】図2
