橋式起重機安全防護裝置背景技術及解決方案

橋式起重機是橫架於車間、倉庫和料場上空進行物料吊運的起重設備。由於它的兩端坐落在高大的水泥柱或者金屬支架上，形狀似橋

，所以又稱“天車”或者“行車”。橋qiao式shi起qi重zhong機ji的de橋qiao架jia沿yan鋪pu設she在zai兩liang側ce高gao架jia上shang的de軌gui道dao縱zong向xiang運yun行xing，起qi重zhong小xiao車che沿yan鋪pu設she在zai橋qiao架jia上shang的de軌gui道dao橫heng向xiang運yun行xing，構gou成cheng一yi矩ju形xing的de工gong作zuo範fan圍wei
，就jiu可ke以yi充chong分fen利li用yong橋qiao架jia下xia麵mian的de空kong間jian吊diao運yun物wu料liao
，不bu受shou地di麵mian設she備bei的de阻zu礙ai。它ta是shi使shi用yong範fan圍wei最zui廣guang、數量最多的一種起重機械。
