I-Double Girder Beam Portal Gantry Crane eyenziwe ngokwezifiso

Amabhande amabili amakhulu e-double girder gantry crane agxunyekwe kuma-outrigger amabili ukuze akhe umumo we-gantry. Ayinayo isiteji sokuhamba esihlukile, ingxenye engaphezulu yebhande eliyinhloko isetshenziswa njengesiteji sokuhamba, futhi ama-railings kanye nezinqola zokuhambisa i-trolley zifakwe phezu kwekhava elingaphezulu lebhande eliyinhloko. Amaplathifomu okuhamba ngezinyawo, ama-railing, kanye nezitebhisi zama-double girder gantry cranes aklanywe ngokuhambisana nemithetho efanele yokuphepha kanye nokucaciswa kwedizayini.

Lolu hlobo luka-crane lugijima kumzila ophansi futhi lusetshenziswa kakhulu ukuphatha kanye nokufaka imisebenzi emayadini okugcina avulekile, iziteshi zikagesi, amachweba kanye namatheminali ezimpahla zikaloliwe. Uma kuqhathaniswa ne-single-girder gantry cranes, ama-double girder beam portal cranes afaneleka kakhulu kumaphrojekthi anamanani amakhulu kanye nezikhathi ezinde zokwakha. Ithuthukisa kakhulu amandla okukhiqiza kanye nokukhiqiza kwemisebenzi yokulayisha nokuthulula, futhi iyisisetshenziswa esibalulekile sokuphakamisa ikhwalithi nokusebenza kahle kokwakhiwa kokupakisha.

Ama-cranes e-Gantry ngokuyisisekelo afakwe ngaphandle. Ngenxa yokuchayeka kaningi emoyeni, emvuleni nasekukhanyeni kwelanga, isakhiwo esiyinhloko kanye nezingxenye ze-double girder gantry crane zizolimala noma zikhubazeke ngenxa yokugqwala, futhi izingxenye zikagesi ezifanele kanye nemishini nakho kuzoba sengozini yokuguga. Lokhu akuthinti nje ukusebenza kahle kwe-gantry crane, kodwa futhi kungase kubangele izingozi zokuphepha emsebenzini. Ngakho-ke, kuyadingeka ukugcina i-gantry crane njalo.

Ukusebenza kanye nempilo yesevisi yendlela ngayinye ye-gantry crane kuncike kakhulu ekugcotshisweni. Okokuqala, hlola ihuku kanye nentambo yocingo ye-crane ukuze ubone ukuthi azikho yini izintambo eziphukile, ukuqhekeka kanye nokugqwala okukhulu, futhi uzihlanze futhi uzigcobe. Okwesibili, hlola i-pulley block, isigubhu kanye ne-pulley nyanga zonke ukuze uthole ukuthi ingabe ikhona yini imifantu, kanye nokuthi amabholothi epuleti elicindezelayo namabhawudi esigubhu ayaqiniswa yini. Uma i-drum shaft igqoke cishe i-5%, kufanele ishintshwe. Lapho ukuguga kodonga lwe-groove kufinyelela ku-8% futhi ukugqoka kwangaphakathi kufinyelela ku-25% we-diameter yangaphakathi yentambo yocingo, kufanele kushintshwe. Ngaphezu kwalokho, ama-bolts of reducer kufanele ahlolwe njalo ukuze kuqinisekiswe ukuthi aqinisiwe.
