單梁起重機上用於承載起重小車等部件的主梁結構一般有單、雙兩種形式，而主梁結構的類型卻可以分為三種：桁架梁、箱梁以及蜂窩梁。這三種單梁起重機主梁結構的命名也體現出了其形態特征

，桁架梁是用焊接的方式將多個角鋼、工gong字zi鋼gang等deng構gou件jian聯lian接jie成cheng桁heng架jia結jie構gou
，箱xiang梁liang則ze是shi將jiang鋼gang板ban焊han接jie成cheng箱xiang式shi形xing態tai的de主zhu梁liang結jie構gou，蜂feng窩wo梁liang要yao特te殊shu一yi點dian，端duan麵mian看kan起qi來lai就jiu是shi一yi個ge等deng腰yao三san角jiao形xing
，由you弦xian杆gan和he有you蜂feng窩wo孔kong的de鋼gang板ban等deng構gou成cheng。三san者zhe相xiang較jiao，桁heng架jia梁liang的de自zi重zhong最zui輕qing、zaojiayezuidi，kangfengxingyezuihao，fengwoliangcizhi
