UJack umilesisiqwenga esiqinileyo se-jacking njengesixhobo esisebenzayo, ngokusebenzisa isibiyeli esiphezulu okanye uzipho lwesibiyeli esisezantsi ngaphakathi kohambo oluncinci ukuvula ubunzima besixhobo sokuphakamisa esincinci sokukhanya. IJack isetyenziswa kakhulu kwiifektri, imigodi, ezothutho kunye namanye amasebe njengokulungisa izithuthi kunye neminye imisebenzi yokuphakamisa, inkxaso kunye neminye imisebenzi. Isakhiwo sayo silula kwaye siqinile, siguquguquka kwaye sinokuthenjwa, kwaye sinokuthwalwa kwaye siqhutywe ngumntu omnye.Isilinganisi seTire isetyenziselwa ukulinganisa ukungalingani kwe-rotor, umatshini wokulinganisa ungowomatshini wokulinganisa oxhaswa nzima, ukuqina kwesakhelo se-swing kukhulu kakhulu, ukungalungelelani kwe-rotor kulungiswa ngumatshini wokulinganisa oguqukayo weziphumo zokulinganisa, ukuze kuncitshiswe ukungcangcazela, ukuphucula ukusebenza kunye nokuphucula umgangatho wemveliso, ukungcangcazela kwe-rotor okanye ukungcangcazela kwe-vibration kwi-vibration inokunciphisa. I-crane ye-Gantry yi-deformation ye-crane yebhulorho, eyaziwa ngokubaI-crane yevenkile esongelayo.Isetyenziselwa ikakhulu ukulayisha kunye nokothula iimpahla kwiyadi yangaphandle, iyadi yezinto eziphathekayo kunye nomthwalo omkhulu. I-crane ye-Gantry isetyenziswa ngokubanzi kwiiyadi ze-port cargo ngenxa yezinga eliphezulu lokusetyenziswa, uluhlu olukhulu lokusebenza, ukuguquguquka okubanzi kunye nokuguquguquka okunamandla.
