Double girder gantry crane ke mofuta oa crane o nang le li-girders tse peli tse bapileng tse tšehelitsoeng ke moralo oa gantry. Hangata e sebelisoa libakeng tsa indasteri le tsa kaho bakeng sa ho phahamisa le ho tsamaisa meroalo e boima. Monyetla o ka sehloohong oa "double girder gantry crane" ke bokhoni ba eona ba ho phahamisa bo phahameng ha bo bapisoa le crane e le 'ngoe ea girder gantry.
Mona ke tse ling tsa likarolo tsa bohlokoa le litšobotsi tsadouble girder gantry cranes:
- Sebopeho: Crane e tšehetsoa ke moralo oa gantry, oo hangata o entsoeng ka tšepe. Li-girders tse peli li behiloe ka mokhoa o tšekaletseng 'me li tsamaisana li bapile. Li-girders li kopantsoe ka maballo a sefapano, ho etsa mohaho o tsitsitseng le o thata.
- Lifting Mechanism: Mochini oa ho phahamisa oa "double girder gantry crane" hangata o na le hoist kapa trolley e tsamaeang ho bapa le mabili. Hoist e na le boikarabelo ba ho phahamisa le ho theola mojaro, ha teroli e fana ka motsamao o otlolohileng ho pholletsa le bolelele ba crane.
- Keketseho ea Bokhoni ba ho Phahamisa: Li-cranes tse peli tsa girder gantry li etselitsoe ho sebetsana le meroalo e boima haholo ha e bapisoa le li-crane tsa girder tse le 'ngoe. Sebopeho sa li-girder tse peli se fana ka botsitso bo betere le botšepehi ba sebopeho, se lumellang bokhoni bo phahameng ba ho phahamisa.
- Span le Bophahamo: Li-cranes tsa girder gantry tse habeli li ka etsoa ho latela litlhoko tse itseng. Sekhahla se bolela sebaka se pakeng tsa maoto a mabeli a gantry, 'me bophahamo bo bolela bophahamo ba ho phahamisa. Litekanyo tsena li lekantsoe ho ipapisitsoe le ts'ebeliso e reriloeng le boholo ba meroalo e lokelang ho phahamisoa.
- Mefuta-futa: Li-cranes tsa girder gantry tse peli li sebetsa ka mokhoa o fapaneng 'me li ka sebelisoa liindastering tse fapaneng tse kang kaho, tlhahiso, thepa le thepa ea likepe. Hangata li sebelisoa libakeng tseo li-cranes tse holimo li sa khoneheng kapa li sa sebetseng.
- Sistimi ea Taolo: Li-cranes tsa girder gantry tse habeli li ka sebetsoa ho sebelisoa litsamaiso tse fapaneng tsa taolo, joalo ka taolo ea pendant, remoutu ea radio, kapa taolo ea khabinete. Sistimi ea taolo e lumella opareitara ho laola metsamao ea crane ka nepo le ts'ebetso ea ho phahamisa.
- Likarolo tsa Tšireletso: Li-cranes tse peli tsa girder gantry li na le likarolo tsa polokeho ho netefatsa ts'ebetso e bolokehileng. Tsena li ka kenyelletsa tšireletso e ngata haholo, likonopo tsa ho emisa ts'ohanyetso, li-switch switch le lialamo tse utloahalang.
Ke habohlokoa ho hlokomela hore litlhaloso le bokhoni ba "double girder gantry crane" li ka fapana ho itšetlehile ka moetsi le mohlala o itseng. Ha u nahana ka tšebeliso ea "double girder gantry crane", ho khothaletsoa ho buisana le moenjiniere ea nang le litsebo kapa mofani oa thepa ea crane ho netefatsa hore crane e finyella litlhoko tsa hau tse khethehileng le litekanyetso tsa polokeho.
Ntle le moo, mona ke lintlha tse ling mabapi le li-cranes tse peli tsa girder gantry:
- Bokhoni ba ho Phahamisa:Li-cranes tsa gantry tse habelili tsebahala ka matla a tsona a phahameng a ho phahamisa, e leng se etsang hore li tšoanelehe bakeng sa ho jara meroalo e boima. Ka tloaelo ba ka phahamisa meroalo ho tloha ho lithane tse 'maloa ho isa ho lithane tse makholo a' maloa, ho itšetlehile ka mohlala o itseng le tlhophiso. Bokhoni ba ho phahamisa bo susumetsoa ke lintlha tse kang bolelele, bolelele, le moralo oa sebopeho sa crane.
- Clear Span: Sebaka se hlakileng sa "double girder gantry crane" se bolela sebaka se pakeng tsa litsi tsa maoto a mabeli. Boemo bona bo lekanya boholo ba bophara ba sebaka sa mosebetsi se ka tlas'a crane. Sebaka se hlakileng se ka etsoa ka mokhoa o ikhethileng ho lumellana le moralo o itseng le litlhoko tsa sebaka sa ho sebetsa.
- Mokhoa oa ho Tsamaea oa Borokho: Mokhoa oa ho tsamaea oa borokho o nolofalletsa motsamao o otlolohileng oa crane haufi le moralo oa gantry. E na le lienjene, likere, le mabili a lumellang crane ho tsamaea hantle le ka nepo ho pholletsa le nako eohle. Hangata mochine o tsamaeang o tsamaisoa ke li-motor tsa motlakase, 'me mefuta e meng e tsoetseng pele e ka kenyelletsa li-drive frequency drives (VFD) bakeng sa taolo e ntlafetseng le ho sebetsa hantle ha matla.
- Hoisting Mechanism: The hoisting mechanism ea double girder gantry crane ke eona e ikarabellang bakeng sa ho phahamisa le ho theola mojaro. Hangata e sebelisa mochini oa motlakase kapa trolley, e khonang ho matha haufi le li-girders. Hoist e kanna ea ba le lebelo la ho phahamisa makhetlo a mangata ho amohela litlhoko tse fapaneng tsa mojaro.
- Tlhophiso ea Boikarabello: Li-cranes tse peli tsa girder gantry li etselitsoe ho sebetsana le lipotoloho tse fapaneng tsa mosebetsi ho ipapisitsoe le matla le makhetlo a ts'ebeliso ea tsona. Likarolo tsa mesebetsi li arotsoe ka mokhoa o bobebe, o mahareng, o boima, kapa o matla, 'me o tsebahatsa bokhoni ba krene ea ho sebetsana le meroalo e sa khaotse kapa nako le nako.
- Lisebelisoa tsa Kantle le Ka hare: Li-cranes tse peli tsa girder gantry li ka sebelisoa ka hare le ka ntle, ho itšetlehile ka litlhoko tse khethehileng. Li-cranes tsa ka ntle tsa gantry li entsoe ka likarolo tse hanyetsanang le maemo a leholimo, joalo ka liphahlo tse sireletsang, ho mamella ho pepesetsoa likarolo tsa tikoloho. Li-cranes tsa ka hare tsa ntlo hangata li sebelisoa litsing tsa tlhahiso, matlong a polokelo le lithupelo.
- Likhetho tsa ho Itloaetsa: Baetsi ba fana ka mefuta e fapaneng ea likhetho tsa ho ikhethela ho etsa li-cranes tse peli tsa girder gantry ho latela lits'ebetso tse ikhethileng. Likhetho tsena li ka kenyelletsa likarolo tse kang li-hoist tse thusang, li-attachments tse khethehileng tsa ho phahamisa, litsamaiso tse khahlanong le ho fofa, le litsamaiso tse tsoetseng pele tsa taolo. Ho itloaetsa ho ka ntlafatsa ts'ebetso le bokhoni ba crane bakeng sa mesebetsi e itseng.
- Tlhophiso le Tlhokomelo: Ho kenya "double girder gantry crane" ho hloka moralo o hlokolosi le botsebi. E kenyelletsa lintlha tse kang ho lokisoa ha fatše, litlhoko tsa motheo, le kopano ea mohaho oa gantry. Tlhokomelo le tlhahlobo ea khafetsa lia hlokahala ho netefatsa ts'ebetso e bolokehileng le e sebetsang ea crane. Hangata bahlahisi ba crane ba fana ka tataiso le tšehetso bakeng sa ho kenya, ho hlokomela le ho rarolla mathata.
Hopola hore lintlha le likarolo tse ikhethileng li ka fapana ho latela moetsi le mohlala oa "double girder gantry crane". Ho bohlokoa ho buisana le litsebi tsa indasteri kapa barekisi ba crane ba ka fanang ka tlhaiso-leseling e nepahetseng ho latela litlhoko le maemo a hau a ikhethileng.
