I-double-beam gantry crane's Girders and Frames yizakhiwo ezishiselwe ndawonye ezingenawo amajoyinti omthungo, anezinga eliphezulu lokuqina okuqondile nokuvundlile. Indlela yokuhamba ye-trolley ishayelwa ngogesi, i-double-beam gantry crane ingahlonywa ukubambana namanye amathuluzi okuphakamisa iziqukathi, ezifanele ukusetshenziswa okuhlukile.
Amandla okuphakamisa i-double-beam gantry crane ingaba amakhulu amathani, futhi isetshenziswa kakhulu ezindaweni zokugcina ezivulekile, izindawo zokugcina izinto zokwakha, izitshalo zikasimende, izimboni zamagwadle, izimboni zokwakha, izimboni zobunjiniyela, amagceke kaloliwe ukulayisha nokuthulula. impahla. I-double beam gantry crane isetshenziswa kakhulu ekuphakamiseni umsebenzi osindayo.
I-double beam gantry crane ilula futhi iyaphatheka, isebenzisa imilenze ukubamba amabhuloho, izihlilingi, namakheshi. Emiklamo ehamba phambili, ama-double girder gantry cranes angase avumele ukuphakama okukhulu ngenxa yokuthi i-hoist imisiwe ngaphansi kwe-beam. Azidingi izinto zokwakha ezengeziwe zemishayo yebhuloho nezinhlelo zemigwaqo yezindiza, ngakho-ke imilenze yokusekela yokwakha kufanele inakekele okwengeziwe. I-double beam gantry crane nayo iyacatshangelwa lapho kunesizathu sokungafaki isistimu ye-runway egxunyekwe ophahleni, futhi ngokuvamile isetshenziselwa izinhlelo zokusebenza ezivulekile lapho imishayo ephelele namakholomu engakwazi ukufakwa, noma angasetshenziswa ngaphansi komqhele okhona webhuloho. uhlelo.
Okhreni abane-double girder ngokuvamile badinga imvume enkulu ngaphezu kokuphakama kweleveli ye-cranes, njengoba inqola ekhuphukayo igibela phezu kwemishayo yebhuloho ku-crane. Isakhiwo esiyisisekelo se-double beam gantry crane ukuthi imilenze namasondo ahamba ngobude besistimu ye-ground beam, enamabhande amabili emilenzeni, futhi i-hoist trolley imisa okwesikhashana ama-boom futhi ihamba phezu kwamabhande.
