橋式起重機的起重電動機相關要求

在工作的過程當中
，橋式起重機一直遵循“啟動、製動
、啟動

、製動”的工作規律，伴隨著電源處於一種通、斷duan電dian的de狀zhuang態tai，故gu稱cheng橋qiao式shi起qi重zhong機ji的de起qi重zhong電dian動dong機ji為wei重zhong複fu短duan時shi工gong作zuo製zhi，且qie起qi重zhong電dian動dong機ji在zai不bu停ting的de反fan轉zhuan過guo程cheng中zhong


，承cheng受shou的de載zai重zhong量liang也ye是shi不bu規gui律lv的de，有you時shi輕qing有you時shi重zhong
，且qie橋qiao式shi起qi重zhong機ji的de起qi重zhong電dian動dong機ji在zai運yun行xing的de過guo程cheng當dang中zhong，由you於yu運yun轉zhuan的de時shi間jian間jian隔ge比bi較jiao短duan，機ji器qi本ben身shen產chan生sheng的de熱re量liang也ye是shi比bi較jiao少shao的de，這zhe樣yang一yi來lai就jiu不bu需xu要yao考kao慮lv負fu載zai的de情qing況kuang，故gu必bi須xu要yao求qiu橋qiao式shi起qi重zhong機ji的de起qi重zhong電dian動dong機ji要yao有you過guo硬ying的de超chao載zai能neng力li。

那麼對於橋式起重機的起重電動機都有哪些相關的要求呢
