大吨位履带起重机长期在野外施工,且施工工地多为空旷区域,遇到雷雨天气时,高耸的臂架极易成为雷电的引下通道,从而使机器遭受雷击。若起重机出现雷击事故,轻则造成电器件损坏,重则引起安全事故,因此做好履带式起重机的防雷工作是非常必要的。本文阐述一套针对履带式起重机的防雷方案,它可以覆盖绝大多数工作幅度,适应所有臂节组合,可以有效减少整机因雷击而损害的概率。1.防雷相关标准目前,国内对于流动式起重机主机生产厂
Large-tonnage crawler cranes have been under construction in the field for a long time and most of the construction sites are open areas. In case of thunderstorm, the towering boom can easily lead to lightning and lead to lightning strikes on the machine. If the crane has a lightning accident, causing damage to electrical components, causing heavy accidents caused by accidents, it is necessary to do a good job crawler crane lightning protection work is very necessary. This article describes a set of anti-thunder caterpillar cranes for the program, which covers most of the scope of work, to adapt to all the boom assembly, can effectively reduce the probability of machine damage due to lightning. 1. Lightning-related standards Currently, the domestic mobile cranes for the host plant
