Cantilever gantry crane ke mofuta o bonoang hangata oa seporo sa gantry crane e sebelisoang ho sebetsana le meroalo e meholo kantle, joalo ka lijarete tsa thepa, boema-kepeng ba leoatle. Crane e le 'ngoe ea beam gantry crane kapa double beam gantry crane e lokela ho khethoa ho latela litlhoko tse ikhethileng mabapi le boima ba mojaro le litlhoko tse ling tse ikhethileng. Ha ho phahamisa meroalo e ka tlase ho lithane tse 50, bolelele bo ka tlase ho limithara tse 35, ha ho na litlhoko tse khethehileng tsa kopo, khetho ea mofuta o le mong oa gantry crane e loketse. Haeba litlhoko tsa girder ea menyako li le bophara, lebelo la ho sebetsa le potlakile, kapa karolo e boima le karolo e telele e atisa ho phahamisoa, joale ho lokela ho khethoa crane ea double beam gantry. The cantilever gantry crane e bōpehile joaloka lebokose, 'me li-girders tse peli li na le litsela tse tšekaletseng,' me maoto a arotsoe ka Mefuta ea A le Mefuta ea U ho latela litlhoko tsa tšebeliso.
Crane e tloaelehileng ea "double girder gantry crane" e sebetsa mesebetsing e tloaelehileng ea mojaro, ea ho theola, ea ho phahamisa le ea ho sebetsana le lijareteng tsa kantle le lijarete tsa terene. The cantilever gantry crane e khona ho jara meroalo e meholo, e boima ho feta libakeng tse kantle, joalo ka boema-kepe, libaka tsa likepe, matlong a polokelo le libaka tsa meaho. Cantilever gantry crane e sebetsoa litseleng tse tsamaeang fatše, 'me e sebelisoa haholo bakeng sa ho laolla le ho laolla mesebetsi libakeng tsa polokelo ea kantle, lipiereng, lifemeng tsa motlakase, likoung tsa likepe le lijarete tsa terene, har'a tse ling. The cantilever gantry crane e sebelisoa libakeng tse fapaneng tse bulehileng tsa mosebetsi bakeng sa ho sebetsana le meroalo e boima kapa thepa, hangata e fumanoang matlong a polokelo, lijareteng tsa terene, lijarete tsa lijana, lijarete tsa scrap, le lijarete tsa tšepe.
Ka lebaka la sebopeho sa eona, gantry crane ea kantle ke sesebelisoa se seholo sa mochini se sebelisoang khafetsa. Li-Gantries li fumaneha ka bokhoni bo tšoanang le li-spans ho li-cranes tsa borokho, 'me li loketse lisebelisoa tsa ka hare le tsa ka ntle. Li-gantries li tšoana le li-cranes tsa borokho, ntle le hore li sebetsa ka lipina tse ka tlaase ho fatše.
