I-semi-gantry crane uhlobo lwe-crane oluhlanganisa izinzuzo ze-gantry crane kanye ne-bridge crane. Ingumshini wokuphakamisa oguquguqukayo ongahambisa imithwalo esindayo ngokuvundlile nangokuqondile ngokunemba nangokunembile.
Umklamo we-semi-gantry crane ufana kakhulu nowe-gantry crane. Uhlangothi olulodwa lusekelwe yisakhiwo sensimbi esiqinile esibizwa ngokuthi i-gantry, kanti olunye uhlangothi lusekelwe yi-trolley enamasondo egijima ku-rail. Umehluko phakathi kwe-semi-gantry crane kanye ne-gantry crane useqinisweni lokuthi owokuqala unomlenze owodwa kuphela ofakwe phansi, kanti omunye umlenze ufakwe ebhamini le-runway elixhunywe esakhiweni sesakhiwo.
Amakhreni ahamba kancanezivame ukusetshenziswa ezicelweni lapho kunesikhala esincane khona, noma lapho isakhiwo esigcwele se-gantry singadingeki khona. Zisetshenziswa nasezicelweni zangaphandle lapho i-gantry egcwele ingeke isebenze ngenxa yezimo zezulu. Ama-semi-gantry cranes anomthamo omkhulu womthwalo futhi angenziwa ngokwezifiso ukuze avumelane nezidingo ezithile zokuphakamisa nokuphatha.
Enye yezinzuzo ezibaluleke kakhulu ze-semi-gantry crane ukuguquguquka kwayo. I-crane ingathuthwa kalula iye ezindaweni ezahlukene, futhi ukuphakama kwayo kungalungiswa ngokwezidingo zokuphakamisa ezahlukahlukene. Ingasetshenziswa futhi ezimbonini ezahlukahlukene, kufaka phakathi ezokukhiqiza, ezokwakha, kanye nezokuthutha.
Ama-semi-gantry cranes nawo aklanyelwe ukuphepha nokuthembeka. Ahlonyiswe ngobuchwepheshe obuthuthukisiwe, njengezinhlelo zokulwa nokushukuma kanye nokuvikelwa kokulayisha ngokweqile, okuqinisekisa ukusebenza okuphephile nokusebenza kahle. Ukwakheka kwe-modular ye-crane kuvumela ukulungiswa nokulungiswa okulula, okunciphisa isikhathi sokungasebenzi futhi kwandise umkhiqizo.
Ekuphetheni, i-i-semi-gantry craneiwumshini wokuphakamisa oguquguqukayo, oguquguqukayo, futhi ophephile ohlinzeka ngezinzuzo ezibalulekile zezinhlelo zokusebenza ezahlukahlukene zokuphakamisa nokuphatha. Umklamo wawo oyingqayizivele unikeza izinzuzo ze-gantry crane kanye ne-bridge crane, okwenza kube yisisombululo esifanele sezimboni ezidinga amakhono okuphakamisa okunzima ezindaweni ezilinganiselwe.
