靜載試驗起重機檢驗中危險因素如何識別

靜jing載zai試shi驗yan起qi重zhong機ji檢jian驗yan中zhong危wei險xian因yin素su如ru何he識shi別bie？靜jing載zai試shi驗yan的de目mu的de是shi檢jian驗yan起qi重zhong機ji及ji其qi部bu件jian的de結jie構gou承cheng載zai能neng力li。使shi小xiao車che或huo電dian動dong葫hu蘆lu，停ting在zai有you效xiao半ban徑jing或huo有效懸臂長度，處
，逐漸加載25倍額定起重量，起升載荷離地麵100mm~200mm後
，懸空10min，卸去載荷目測檢査是否出現變形
，油漆剝落或對起重機的性能和安全有影響的損壞，檢査連接處是否出現鬆動或損壞。
