    懸臂拚裝是將已預製好的梁段（混凝土梁或鋼梁）或(huo)拱(gong)段(duan)，用(yong)懸(xuan)臂(bi)吊(diao)機(ji)起(qi)吊(diao)到(dao)已(yi)完(wan)成(cheng)構(gou)造(zao)端(duan)部(bu)停(ting)止(zhi)拚(pin)裝(zhuang)，一(yi)個(ge)節(jie)段(duan)拚(pin)裝(zhuang)終(zhong)了(le)後(hou)，將(jiang)吊(diao)機(ji)挪(nuo)動(dong)至(zhi)下(xia)一(yi)節(jie)段(duan)，然(ran)後(hou)停(ting)止(zhi)下(xia)一(yi)節(jie)段(duan)的(de)拚(pin)裝(zhuang)，懸(xuan)臂(bi)不(bu)時(shi)增(zeng)加(jia)，直(zhi)至(zhi)構(gou)造(zao)在(zai)跨(kua)中(zhong)合(he)攏(long)，或(huo)直(zhi)接(jie)拚(pin)至(zhi)下(xia)一(yi)墩(dun)台(tai)上(shang)。[1]
