I-portal gantry gantry gantry

Ama-girders amabili e-girter gane's main crane afakwa kuma-offigger amabili ukwakha isimo se-gantry. Ayinayo ipulatifomu ehlukile yokuhamba, ingxenye engenhla ye-girder eyinhloko isetshenziswa njengengxenyekazi yokuhamba, kanti izitimela nezemoto ezithwala izitimela kanye ne-trolley kanye ne-trolley kanye ne-trolley. Amapulatifomu okuhamba, izitimela kanye nezitebhisi ze-double girter cranes zenzelwe ngokuya ngemithetho efanelekile yezokuphepha nezincazelo zokwenziwa.

Lolu hlobo lwe-crane lusebenza emhlabathini ithrekhi futhi lusetshenziselwa ikakhulukazi ukuphatha nokusebenza kwemisebenzi emaceleni avulekile okugcina umoya, iziteshi zamandla, amachweba kanye nezindleko zezimpahla zezimoto. Uma kuqhathaniswa nama-gantry ama-gantry ama-girter, i-girder ephakeme ye-girder beam gantry ilungele amaphrojekthi anenani elikhulu nezikhathi zokwakha ezinde. Kuthuthukisa kakhulu umthamo wokukhiqiza kanye nokukhiqiza kokulayisha nokulayisha imisebenzi, futhi kuyimishini yokuphakamisa ebalulekile yekhwalithi nokusebenza kahle kokwakhiwa kwamaphakeji.

Ama-Cranes e-Gantry afakiwe ngokuyisisekelo ngaphandle. Ngenxa yokuchayeka njalo emoyeni, imvula kanye nokukhanya kwelanga, isakhiwo esikhulu kanye nezinto ze-double girder crane zizonakaliswa noma zikhubazeke ngenxa yokugqwala, kanye nezinto ezifanele zikagesi futhi zizothambekele ekugugeni. Lokhu akuhlathi kuthinta kuphela ukusebenza kahle kwe-gantry crane, kodwa futhi kungadala izingozi zokuphepha emsebenzini. Ngakho-ke, kuyadingeka ukugcina i-gantry crane njalo.

Ukusebenza okusebenzayo kanye nempilo yensiza yendlela ngayinye ye-gantry crane kuncike ekuthambezini. Okokuqala, hlola i-hook nentambo yentambo ye-crane ukuze ubone ukuthi ngabe kukhona izintambo eziphukile, imifantu kanye nokugqwala okukhulu, futhi kuhlanzekile futhi kugcobe. Okwesibili, hlola ibhulokhi ye-pulley, isigubhu kanye pulley njalo ngenyanga ukuthola ukuthi ngabe kukhona imifantu, nokuthi ngabe ama-bolts acindezelwe amapuleti kanye nesigubhu sesisekelo sesifuba aqiniswa. Lapho shaft yesigubhu sigqokwa cishe ngo-5%, kufanele ithathelwe indawo. Lapho ukugqokwa kodonga lwe-groove kufinyelela ama-8% futhi ukugqokwa kwangaphakathi kufinyelela ku-25% wobubanzi bentambo yangaphakathi yentambo yocingo, kufanele ithathelwe indawo. Ngaphezu kwalokho, ama-bolts omnciphisi kufanele ahlolwe kaningi ukuqinisekisa ukuthi ayaqiniswa.
