Ama-cranes we-box girder asephenduke isakhi esibalulekile ekwakhiweni kwensimbi kwanamuhla. Zenzelwe ukuphakamisa nokuhambisa imithwalo enkulu esindayo ezungeze indawo yokwakha, ukuhlinzeka ngesisombululo esithembekile nesisebenzayo sokuphathwa kwezinto ezibonakalayo.
Enye yezinzuzo ezinkulu kunazo zonke ze-Box Girder Cranes yikhono labo lokuhambisa imithwalo ngendlela ephelele futhi eqondile. Lokhu kusebenza ikakhulukazi lapho usebenza kumaphrojekthi amakhulu wengqalasizinda lapho ukuphepha kubaluleke kakhulu. Ama-crane opharetha angakwazi ukulawula ukunyakaza kwe-crane kalula, aqinisekise ukuthi imithwalo iphakanyiswe futhi ihanjiswa ngokuphepha nangengozi encane yezingozi.
Ama-cranes e-box girder nawo ahlala isikhathi eside futhi akhiwe ukumelana nezimo zangaphandle ezinzima zendawo yokwakha. Zenziwe ngezinto eziqinile, ezisindayo zomsebenzi, ezizinika isikhathi sokuphila eside. Lokhu kusho ukuthi bangasetshenziswa isikhathi nesikhathi futhi kumasayithi okwakha iminyaka eminingi azayo.
Enye inzuzo yebhokisi le-girder cranes ukuguquguquka kwabo okuhlukahlukene. Zilungele izicelo ezahlukahlukene zokuphakamisa, kusuka ekuhambeni kwamaphaneli kakhonkolo elandelanayo kuya ezinhlangeni zensimbi nezinye izinto ezisetshenziswa ekwakhiweni kwensimbi. Zingalungiswa ukuze zivumelane nezidingo ezithile zephrojekthi, eqinisekisa ukuthi i-crane ilungele inhloso futhi ikwazi ukuphatha imithwalo edingekayo.
Ngaphezu kwalokho, ama-cranes e-box girder ayaziwa ngejubane labo kanye nokusebenza kahle ekutholeni izinto zokwakha ezandleni zabo okuhlosiwe. Bangakwazi ukuthutha imithwalo esindayo ngokushesha nangokuphepha kusuka kolunye uhlangothi lwendawo yokwakha kuya kolunye, olungazonga isikhathi nemali yephrojekthi. Lokhu kubalulekile ikakhulukazi kumaphrojekthi wokwakha amakhulu, lapho ukubambezeleka kungaba nemiphumela emibi kwisabelomali sephrojekthi kanye nomugqa wesikhathi.
Ekuphetheni, ama-cranes e-box girder ayithuluzi elisemqoka lemisebenzi yokwakha yensimbi. Ukunemba kwabo, ukuqina, ukuguquguquka, ukuguquguquka nokusebenza kahle kubenze balungele ukuphatha imithwalo esindayo kumasayithi okwakha. Lokhu kuphumela ezimweni zokusebenza eziphephile, izikhathi eziguquguqukayo ngokushesha, kanye nephrojekthi yokwakha esebenza ngempumelelo.
