Double girder gantry cranes ke khetho e tsebahalang bakeng sa ts'ebetso ea ho phahamisa boima e hlokang bokhoni bo bongata le bolelele bo bolelele ho feta li-cranes tsa single girder gantry. Li entsoe le ho etsoa ka meaho ea tšepe e matla 'me li fumaneha ka mefuta e mengata ea ho phahamisa, ho tloha ho lithane tse 5 ho isa ho tse fetang 600.
Likarolo tsa li-cranes tse peli tsa girder gantry li kenyelletsa:
1. Kaho ea tšepe e matla le e tšoarellang bakeng sa ts'ebetso e ka tšeptjoang le ea nako e telele.
2.Customizable bolelele le span ho finyella litlhoko tse itseng tsa ho phahamisa.
3. Likarolo tsa ts'ireletso tse tsoetseng pele, joalo ka ts'ireletso ea boima bo feteletseng le mariki a tšohanyetso.
4.Smooth le ts'ebetso e sebetsang ea ho phahamisa le ho theola ka lerata le fokolang.
5. Ho bonolo ho sebetsa li-control bakeng sa motsamao o nepahetseng.
6. Litlhoko tse tlaase tsa tlhokomelo bakeng sa ho fokotsa nako le litšenyehelo tsa ho sebetsa.
7. E fumaneha ka litlhophiso tse fapaneng, joalo ka gantry e felletseng kapa e nyane, ho latela ts'ebeliso e khethehileng.
Li-cranes tse peli tsa girder gantry li loketse mefuta e fapaneng ea liindasteri, ho kenyelletsa le ho tsamaisa thepa, kaho le ho etsa thepa, 'me li loketse ho phahamisa thepa le thepa e boima libakeng tsa kantle kapa tsa kahare.
Li-cranes tsa girder gantry cranes ke li-cranes tse boima haholo tse etselitsoeng ho phahamisa le ho tsamaisa meroalo e boima haholo. Ka tloaelo li na le bolelele bo fetang 35m mme li khona ho jara meroalo e fihlang ho lithane tse 600. Li-cranes tsena li sebelisoa hangata liindastering tse kang ho etsa tšepe, ho haha likepe, le ho etsa mechini e boima, hammoho le mabaleng a likepe le likoung bakeng sa ho laolla le ho laolla likepe tse tsamaisang thepa.
Moqapi oa li-cranes tse peli tsa girder gantry ke tse khethehileng haholo, 'me tlhahiso ea tsona e hloka tsebo e phahameng le tsebo. Li-girders tse peli li hokahantsoe ke teroli e tsamaeang ka bolelele ba nako, e lumellang crane ho tsamaisa mojaro ka litsela tse tšekaletseng le tse theohileng. Crane e ka boela ea hlomelloa ka mekhoa e mengata ea ho phahamisa, joalo ka li-electromagnets, hook le grabs, ho lumellana le lits'ebetso tse fapaneng.
Ka kakaretso, li-double girder gantry cranes ke sesebelisoa se ka tšeptjoang le se sebetsang sa ho tsamaisa meroalo e boima ho potoloha libaka tsa indasteri, likoung le libaka tsa likepe. Ka moralo o nepahetseng le tlhahiso, li-cranes tsena li ka fana ka lilemo tsa ts'ebeletso e sebetsang hantle.
Double girder gantry crane e etselitsoe ho phahamisa le ho tsamaisa meroalo e boima libakeng tse fapaneng. Moralo le tlhahiso ea li-cranes tse habeli tsa girder gantry li kenyelletsa lits'ebetso tse 'maloa tse netefatsang ts'epahalo, polokeho le ts'ebetso ea tsona.
Mohato oa pele oa ho rala le ho etsa li-cranes tsena o kenyelletsa ho khetha lisebelisoa le likarolo tse nepahetseng. Ts'epe e sebelisoang ts'ebetsong ea tlhahiso e tlameha ho ba le matla a phahameng le khanyetso e ntle ea kutu ho mamella maemo a thata a ho sebetsa. Theknoloji e tsoetseng pele ea welding e boetse e sebelisoa ho hokahanya likarolo tse sa tšoaneng tsa crane.
Sistimi ea meralo e thusoang ke komporo e sebelisoa ho theha mofuta o nepahetseng oa 3D oa crane, o sebelisetsoang ho ntlafatsa sebopeho le ho fokotsa boima ba crane ha e ntse e boloka matla le ho tšoarella ha eona. Sistimi ea motlakase ea gantry crane e etselitsoe ho netefatsa ts'ebetso e nepahetseng, ts'epahalo le polokeho.
Tlhahiso e etsahala likopanong tse khethehileng tse nang le mekhoa e thata ea ho laola boleng. Lihlahisoa tsa ho qetela li lekoa ka matla le ho hlahlojoa pele li tlisoa ho moreki. Gantry crane ena ke sesebelisoa se ka tšeptjoang haholo le se sebetsang hantle se khonang ho phahamisa le ho tsamaisa meroalo e boima habonolo.
