Thecrane e nang le girder e habelike tharollo ea ho phahamisa boima e atisang ho sebelisoa liindastering tse hlokang ho sebetsana le thepa e matla, e phahameng. Mofuta ona oa crane o na le li-girders tse peli tse bapileng tse bophara ba sebaka sa mosebetsi, tse fanang ka botsitso bo boholo le bokhoni ba ho jara meroalo ho feta li-crane tsa single-girder. Li-cranes tsena tse holimo li loketse lits'ebetso tse joalo ka tlhahiso ea tšepe, kopano ea likoloi, kaho ea likepe, le libaka tse ling tse batloang haholo moo ho nepahala le ho tšoarella ho hlokahalang.
Ha u nahana ka litharollo tsa ho phahamisa boima, ho utloisisathipa e habelieot theko ea cranee bohlokoa bakeng sa ho etsa tekanyetso ea merero e meholo ea indasteri.
Sebopeho sa acrane e nang le girder e habelihangata e kenyelletsa:
Li-Double Girders: Li-girders tse peli tsa mantlha tse jarang moroalo, tse fang crane bokhoni bo phahameng ba ho phahamisa thepa e boima.
Literaka tsa ho Qetella: Li fumaneha lipheletsong tsa li-girders, tsena li thusa ho tsamaea tseleng ea sefofane ea double girder eot crane, e nolofalletsang ho tsamaea ka tsela e tšekaletseng ho pholletsa le sebaka sa mosebetsi.
Hoist le Trolley: E behiloe pakeng tsa li-girders tse peli, hoist le trolley li tsamaea ka bophara ba li-girders, e leng ho nolofalletsang motsamao o otlolohileng le o otlolohileng.
Sistimi ea Likoloi tsa Motlakase le Taolo: Thedouble girder eot craneho sisinyeha, ho phahamisa, le mesebetsi e meng e laoloa ka enjene ea motlakase, hangata e nang le taolo e hole kapa radio bakeng sa ts'ebetso e bolokehileng le e sebetsang hantle.
Thethipa e habelieot theko ea cranee ka fapana haholo ho latela litlhaloso tse joalo ka boholo ba moroalo, bolelele le likhetho tsa ho iketsetsa.
Tlhokomelo ea kamehla ea likarolo tsa crane-joalo ka bohole, litsamaiso tsa taolo, le moralo oa sebopeho-e bohlokoa bakeng sa ts'ebetso e sireletsehileng le e sebetsang. Mananeo a tlhokomelo a lokela ho kenyelletsa tlhahlobo ea enjene, litsamaiso tsa mariki, le likarolo tse jarang meroalo ho netefatsa ho ts'epahala le ho thibela ho senyeha ho sa lebelloang.
