Ginda kabilingaphezuluamakhonsathayakhelwe ukuphakamisa ukuphathwa kwezinto ezisindayo zamathani angaphezu kwama-20. Ngakho-ke, girder kabilingaphezuluAma-Cranes angabizwa nangokubizwa ngokuthi ama-cranes ashubile ebhuloho. Ama-Cranes aphindwe kabili awela ama-Cranes ahlelwe ngokucushwa okuhlukahlukene kwe-crane ephezulu, kufaka phakathi ama-trolleys ahamba ngezinyawo, anezinto ezihlotshisiwe ezihlotshiswe ngemishini, anjwe ngaphansi kwezimpawu zokuphepha eziphezulu, ezisetshenziselwa ukuphepha okuphezulu, ukuthembeka okuphezulu kanye ukuqina.
Umthamo wokulayisha imvamisa isizathu esiyinhloko sokukhetha a-biliusebe lokukhanya ngaphezulu kwe-crane. I-Double Girder Overhead i-Cranes iyindleko kanye nesikhala Ukulondolozwa kwesixazululo uma imithwalo esekwe ngaphezulu kwamathani ayi-15 kudingeka iphakanyiswe ngaphakathi komjikelezo wokusebenza njalo.
Ukuphakama kwe-hook okuthuthukile. -BiliBeam Bridge Ama-Cranes afaka i-trolley ehamba ngaphezulu kwebhuloho, ngaleyo ndlela akhuphule ukuphakama kwegwegwe. Lokhu kwenza opharetha ukuthi aphakamise izinto ezinde futhi ezinde nezinto zokwakha ngaphakathi kwendawo yomsebenzi ngokuqhathaniswa ne-girder crane eyodwa ephansiisivimbo trolley ne-most.
Kukhona ama-hoist asizayo kugongolo ngalunye. Ama-Cranes angeziwe angangezwa kwi-girder eyodwa ukuze angeze amaphuzu amaningi wokuphakamisa e-crane ephezulu. Lawa ma-Cranes angazungeza omunye nomunye ngoba awekho kugongolo olufanayo.
Ngaphesheya kwamabanga amade.Le khasi20 Tonhead craneFuthi ingakwazi ukukwenza amabanga amade ngoba ukwakheka okufanayo kwe-girder kunamandla amakhulu kunawo wonke umklamo we-girder.
Ukusebenza okunamandla. Ukusebenza okuphezulu kakhulu ngenxa yokubonga okuphindwe kabili kwe-girder yesivinini eside kakhulu futhi esisezingeni eliphakeme. Ukuphakama okuphezulu kakhulu okuphezulu, njengoba isicoco somthwalo singaphakanyiswa phakathi kwezimbotshana ezimbili ze-crane.
Leli20 Tonhead craneizophatha kalula imithwalo esindayo nezinsimbi ngisho naphezulu kune20 amathani. Hhayi lokhu kuphela, kusebenza kahle ngisho nangesivinini esikhulu kakhulu.
