Crane ea borokho bo tlase, eo hape e tsejoang e le crane ea borokho e tsamaeang ka tlas'a metsi kapa underslung bridge crane, ke mofuta oa crane o ka holimo o sebetsang holim'a tsamaiso ea litsela tse phahameng. Ho fapana le li-crane tse tloaelehileng tse holim'a borokho tse nang le sekema sa borokho se mathang ka holim'a maballo a tsela ea lifofane, crane ea borokho e leketlileng e na le sekele ea borokho e tsamaeang ka tlas'a maballo a tsela. Mona ke lintlha le likarolo tsa li-cranes tsa underhung bridge:
Tlhophiso: Li-cranes tsa borokho tse ka tlas'a borokho hangata li na le girder ea borokho, literaka tsa ho qetela, kopano ea li-hoist/trolley, le tsamaiso ea litsela tsa lifofane. Mohaho oa borokho, o jereng hoist le trolley, o behiloe ka tlase ho maballo a litsela tsa lifofane.
Runway System: Sistimi ea lipalangoang e kentsoe holim'a sebopeho sa moaho mme e fana ka tsela ea hore krene e tsamaee e tšekaletse. E na le maballo a litselana tsa lifofane a bapileng a ts'ehetsang thipa ea borokho. Mabala a litsela hangata a emisoa mohahong oa mohaho ho sebelisoa li-hangers kapa li-brackets.
Bridge Girder: The bridged girder ke borokho bo tšekaletseng bo pharallang lekhalo pakeng tsa maballo a tsela ea sefofane. E tsamaea tseleng ea lifofane e sebelisa mabili kapa lirolara tse kentsoeng literakeng tse qetellang. Mohaho oa borokho o tšehetsa kopano ea hoist le trolley, e tsamaeang ka bolelele ba girder ea borokho.
Kopano ea Hoist le Trolley: Kopano ea hoist le trolley e ikarabella ho phahamisa le ho tsamaisa meroalo. E na le mochini oa motlakase kapa oa letsoho o behiloeng holim'a trolley. Teroli e matha ho bapa le girder ea borokho, e lumellang seisi ho emisa le ho tsamaisa meroalo ho pholletsa le sebaka sa mosebetsi.
Flexibility: Li-cranes tsa underhung tsa borokho li fana ka maemo a bonolo mabapi le ho kenya le ho sebelisoa. Hangata li sebelisoa litsing tseo ho tsona headroom e fokolang kapa moo meaho e teng e ke keng ea tšehetsa boima ba crane ea setso. Li-cranes tsa underhung li ka kengoa meahong e mecha kapa tsa kengoa hape meahong e teng.
Lisebelisoa tsa Tlhahiso: Li-cranes tsa Underhung hangata li sebelisoa litsing tsa tlhahiso ho tsamaisa thepa e tala, likaroloana le lihlahisoa tse felileng haufi le mela ea kopano. Li thusa ho beha mochini o boima, lisebelisoa le lisebelisoa ka nepo le ka nepo nakong ea ts'ebetso ea tlhahiso.
Libaka tsa polokelo le Litsi tsa Kabo: Li-cranes tse tlas'a marulelo li sebelisoa libakeng tsa polokelo le litsing tsa kabo ho sebetsana le ho tsamaisa thepa, liphalete le lijana. Ba thusa ho tsamaisa lihlahisoa ka har'a libaka tsa polokelo, ho kenya le ho theola literaka, le ho hlophisa thepa.
Indasteri ea Likoloi: Li-cranes tsa Underhung li bapala karolo ea bohlokoa indastering ea likoloi. Li sebelisetsoa mesebetsi e kang ho phahamisa le ho beha litopo tsa likoloi nakong ea kopano, ho tsamaisa likarolo tse boima tsa likoloi haufi le mela ea tlhahiso, le ho laela / ho theola thepa ho tsoa literakang.
Indasteri ea sepakapaka: indastering ea sepakapaka, li-cranes tse fanyehiloeng ka tlas'a lefatše li sebelisoa bakeng sa ho sebetsana le ho kopanya likarolo tse kholo tsa sefofane, joalo ka mapheo le li-fuselage. Li thusa ho beha likarolo tsena tse boima le ho tsamaea hantle, ho netefatsa hore ho na le mekhoa e metle ea tlhahiso.
Metal Fabrication: Underhung cranes hangata e fumanoa meahong ea masela a tšepe. Li sebelisetsoa ho tšoara le ho tsamaisa lishiti tse boima tsa tšepe, maballo le likarolo tse ling tsa sebopeho. Li-cranes tsa underhung li fana ka bokhoni bo hlokahalang ba ho phahamisa le ho tsamaisa mesebetsi e fapaneng ea masela, ho kenyeletsoa ho cheselletsa, ho seha le ho etsa ts'ebetso.
Li-cranes tse ka tlas'a marulelo li fumana ts'ebetso liindastering tse ngata le libakeng tseo ho tsona ho sebetsang ka mokhoa o nepahetseng le ho phahamisa mesebetsi e hlokahalang.Ho feto-fetoha ha bona, matla a ho jara le ho feto-fetoha ha maemo ho etsa hore e be letlotlo la bohlokoa liindastering tse ngata moo ho sebetsana ka katleho le thepa le ho phahamisa mesebetsi ho bohlokoa.
