本文介绍动臂式起重机相互靠近时防止碰撞的方法。当两台起重机相互靠近时,防止碰撞是一个极为重要的安全问题。以往在桥式起重机上采用光电式、超声波和微波等检测手段来检测起重机之间的接近状况,从而使互相靠近的二台起重机的一台自动停止。但这种方法对于需作变幅、旋转等复杂动作的动臂式起重机是不适用的。因为动臂式起重机采用上述桥式起重机的防止碰撞的办法,只能对超重机的柱身、门腿等 This article describes how to prevent collisions when the boom-type cranes approach each other. Preventing collisions is an extremely important safety issue when two cranes approach each other. In the past on the bridge crane using photoelectric, ultrasonic and microwave detection means to detect the proximity between the crane, so that one of the two cranes close to each other automatically stop. However, this method is not suitable for boom-type cranes that require complex movements such as luffing and rotation. Because of the use of the above-mentioned overhead traveling cranes to prevent collision of the crane, only the column on the heavy machine, legs, etc.
