I-Gantry Crane Yesigxobo Esiphindwe Kabili Esenziwe Ngokwezifiso

Ama-girder amabili amakhulu e-double girder gantry crane afakwe kuma-outrigger amabili ukuze akhe isimo se-gantry. Ayinaso isiteji sokuhamba esihlukile, ingxenye engenhla ye-girder eyinhloko isetshenziswa njengesiteji sokuhamba, kanti izinsimbi zokuqondisa kanye nezinqola zokuqondisa inqola zifakwe esembozweni esiphezulu se-girder eyinhloko. Amapulatifomu okuhamba, izinsimbi zokuqondisa, kanye nezitebhisi zama-double girder gantry crane aklanywe ngokuhambisana nemithethonqubo yokuphepha efanele kanye nemininingwane yokuklama.

Lolu hlobo lwe-crane lusebenza emzileni ophansi futhi lusetshenziswa kakhulu ekuphatheni nasekufakeni imisebenzi ezindaweni zokugcina izinto ezivulekile, eziteshini zikagesi, emachwebeni nasezikhumulweni zemithwalo yesitimela. Uma kuqhathaniswa nama-crane e-gantry angama-single-girder, ama-crane e-gantry e-portal gantry enziwe ngokwezifiso afaneleka kakhulu kumaphrojekthi anobuningi obukhulu kanye nezikhathi zokwakha ezinde. Ithuthukisa kakhulu amandla okukhiqiza kanye nokukhiqiza kwemisebenzi yokulayisha nokulayisha, futhi iyimishini yokuphakamisa eyinhloko yekhwalithi kanye nokusebenza kahle kokwakhiwa kokupakisha.

Ama-crane e-gantry afakwa ngaphandle. Ngenxa yokuchayeka njalo emoyeni, emvuleni naselangeni, isakhiwo esiyinhloko kanye nezingxenye ze-double girder gantry crane zizolimala noma zikhubazeke ngenxa yokugqwala, kanti izingxenye zikagesi ezifanele kanye nemishini nazo zizoguga. Lokhu akuthinti nje kuphela ukusebenza kahle kwe-gantry crane, kodwa futhi kungabangela izingozi zokuphepha emsebenzini. Ngakho-ke, kubalulekile ukugcina i-gantry crane njalo.

Ukusebenza kahle kanye nokuphila kwenkonzo yendlela ngayinye yokusebenza kwe-gantry crane kuncike kakhulu ekugcotshweni. Okokuqala, hlola intambo ye-hook nentambo ye-crane ukuze ubone ukuthi kukhona izintambo eziphukile, imifantu kanye nokugqwala okukhulu, bese uzihlanza futhi uzigcobe. Okwesibili, hlola i-pulley block, i-drum kanye ne-pulley njalo ngenyanga ukuze unqume ukuthi kukhona imifantu, nokuthi ama-pressing plate bolts nama-drum base bolts aqinisiwe yini. Uma i-drum shaft igqokwe cishe ku-5%, kufanele ishintshwe. Uma ukuguguleka kodonga lomsele kufinyelela ku-8% kanti ukuguguleka kwangaphakathi kufinyelela ku-25% wobubanzi bangaphakathi bentambo yentambo, kufanele kushintshwe. Ngaphezu kwalokho, ama-bolts e-reducer kufanele ahlolwe njalo ukuqinisekisa ukuthi aqinisiwe.
