Li-Cranes tsa Borokho bo Felletseng ba Single Girder
Sekhahla se le seng li-cranes tsa borokho tse ka holimo li khetholloa ka moralo oa tsona o bonolo le litšenyehelo tse tlaase. Li loketse lisebelisoa tsa ho phahamisa tse bobebe le lits'ebetso moo li-headroom li nang le moeli. Li-cranes tsena hangata li fumanoa lithupelong tse nyane le lifemeng. Moralo oa bona o kopaneng o li etsa hore li tšoanelehe bakeng sa libaka tse moqotetsane ha li bapisoa le li-cranes tse peli tsa girder. Leha ho le joalo, boima ba bona ba mojaro hangata bo tlase.
Li-Cranes tsa Double Girder Overhead Bridge
Double girder li-cranes tsa borokho tse ka holimo e fana ka matla a ho phahamisa a holimo mme e etselitsoe meroalo e boima. Li fana ka botsitso bo boholo 'me hangata li sebelisoa libakeng tse kholo tsa indasteri moo litlhoko tse kholo tsa ho phahamisa li atileng. Kaho e matla ea li-cranes tse peli tsa girder e lumella lits'ebetso tse hlokang ho feta. Le hoja e le theko e boima ho feta li-crane tsa girder tse le 'ngoe, ke khetho e ratoang bakeng sa ho phahamisa mosebetsi o boima.
Li-Cranes tse ling tse Khethehileng tsa Overhead Bridge
Ka ntle ho meralo e le 'ngoe le e habeli ea girder, ho na le tse ikhethang li-cranes tsa borokho tse ka holimo tse kang: li-jib cranes (tse atisang ho sebelisoa bakeng sa litlhoko tse nyenyane tsa ho phahamisa sebakeng sa heno), li-cantilever cranes (tse fetelang ka nģ'ane ho mohaho oa tšehetso), le li-semi-gantry cranes (ho kopanya likarolo tsa borokho le li-gantry cranes). Khetho e itšetlehile haholo ka litlhoko tse khethehileng tsa kopo.
Litlhaloso tsa Bohlokoa le Lits'oants'o
Ho khetha e loketseng borokho bo ka holimo-limo e hloka ho hlahlojoa ka hloko ha lintlha tse 'maloa tsa bohlokoa:

Polokeho le Tlhokomelo
Tšireletseho ke ea bohlokoa ha e sebetsa li-cranes tsa borokho tse ka holimo. Litlhahlobo tsa khafetsa, koetliso ea basebelisi, le ho latela melao ea ts'ireletso ke tsa bohlokoa. Tlhokomelo e nepahetseng, ho kenyeletsoa litlolo le licheke tsa likaroloana, e lelefatsa bophelo ba krene le ho fokotsa kotsi ea likotsi.

Ho Fumana Mofani oa Crane ea Borokho bo Loketseng
Ho bohlokoa ho khetha morekisi ea tšepahalang. Mofani oa thepa ea ka tšeptjoang o tla fana ka tataiso ea litsebi, a fane ka mefuta e mengata ea li-crane ho lumellana le litlhoko tse fapaneng, le ho fana ka tšehetso e tsoelang pele le tlhokomelo. Ha u batla a borokho bo ka holimo-limo, nahana ka lintlha tse kang botumo, phihlelo, tiisetso, le tšebeletso ea ka mor'a thekiso. Bakeng sa khetho e pharaletseng ea li-crane tsa boleng bo holimo le lisebelisoa tse amanang le tsona, nahana ka ho hlahloba likhetho ho tsoa ho barekisi ba tsebahalang joalo ka ba fumanoang ho Hitruckmall. Ba fana ka mefuta e fapaneng ea litharollo ho fihlela litlhoko tse fapaneng tsa ho sebetsana le thepa ea indasteri. Hopola ho lula u beha polokeho pele 'me u khethe crane e loketseng ts'ebeliso ea hau e ikhethileng.
Tataiso ena e sebetsa e le qalo ea kutloisiso li-cranes tsa borokho tse ka holimo. Ho khothaletsoa lipatlisiso tse ling mabapi le mefuta e ikhethileng ea crane le ho buisana le litsebi tsa indasteri pele u etsa qeto ea ho qetela ea ho reka.
