起重機(crane)運yun行xing機ji構gou一yi般ban隻zhi用yong四si個ge主zhu動dong和he從cong動dong車che輪lun，如ru果guo起qi重zhong量liang很hen大da
，常chang用yong增zeng加jia車che輪lun的de辦ban法fa來lai降jiang低di輪lun壓ya。當dang車che輪lun超chao過guo四si個ge時shi，必bi須xu采cai用yong鉸jiao接jie均jun衡heng車che架jia裝zhuang置zhi，使shi起qi重zhong機ji的de載zai荷he均jun勻yun地di分fen布bu在zai各ge車che輪lun上shang。

橋qiao架jia的de金jin屬shu結jie構gou由you主zhu梁liang和he端duan梁liang組zu成cheng
，分fen為wei單dan主zhu梁liang橋qiao架jia和he雙shuang梁liang橋qiao架jia兩liang類lei。單dan主zhu梁liang橋qiao架jia由you單dan根gen主zhu梁liang和he位wei於yu跨kua度du兩liang邊bian的de端duan梁liang組zu成cheng，雙shuang梁liang橋qiao架jia由you兩liang根gen主zhu梁liang和he端duan梁liang組zu成cheng。

主zhu梁liang與yu端duan梁liang剛gang性xing連lian接jie，端duan梁liang兩liang端duan裝zhuang有you車che輪lun
，用yong以yi支zhi承cheng橋qiao架jia在zai高gao架jia上shang運yun行xing。主zhu梁liang上shang焊han有you軌gui道dao，供gong起qi重zhong小xiao車che運yun行xing。橋qiao架jia主zhu梁liang的de結jie構gou類lei型xing較jiao多duo比bi較jiao典dian型xing的de有you箱xiang形xing結jie構gou、四桁架結構和空腹桁架結構。
