Ama-cranes angaphezulu angumshini obalulekile ezimbonini eziningi, okuhlanganisa nemboni yokugaya amaphepha.Izigayo zamaphepha zidinga ukuphakanyiswa okunembayo kanye nokunyakaza kwemithwalo esindayo kuyo yonke inqubo yokukhiqiza, kusukela ezintweni ezingavuthiwe ukuya emikhiqizweni ephelile.I-Crane eyisikhombisa engaphezulu ihlinzeka ngesixazululo esifanelekile sokuphakamisa izigayo zephepha.
Okokuqala,ama-cranes angaphezuluukunikeza ukuphepha okuthuthukisiwe, okubaluleke kakhulu kunoma iyiphi indawo yokukhiqiza.Lawa ma-cranes aklanyelwe ukuphakamisa nokuthutha izinto ezisindayo, ukuqinisekisa ukuthi umthwalo uphakanyiswa ngokuphepha nangokuvikelekile.Ngaphezu kwalokho, ama-cranes angaphezulu angathwala imithwalo emikhulu engaba nzima noma engenakwenzeka ngabantu ukuyiphakamisa, enciphisa ingozi yokulimala kubasebenzi.
Okwesibili, ama-cranes angaphezulu enziwe ngokwezifiso kakhulu, okuwenza alungele ukusetshenziswa ezigayweni zephepha.Idizayini ye-crane ingalungiswa kalula ukuze ihlangabezane nezidingo ezithile zebhizinisi, okuhlanganisa ukuphatha izinto ezisindayo noma ukukhiqizwa kwevolumu ephezulu.Lesi sici siqinisekisa ukuthi izigayo zephepha zingahlanganisa kalula ama-cranes aphezulu ezinqubweni zabo zokukhiqiza, okwandisa ukusebenza kahle okuphelele.
Okwesithathu, ama-cranes angaphezulu avumela abaqhubi bezitshalo ukuthi baphathe izinto ngendlela efanele futhi ngokushesha, bakhulise umthamo wokukhiqiza.Lawa ma-cranes angakwazi ukuphakamisa, ukunyakaza noma ukubeka imithwalo esindayo noma emikhulu ngendlela engenamthungo nephumelelayo, ngokuphazamiseka okuncane enqubweni yokukhiqiza.Lokhu kusebenza kahle kwandisa umkhiqizo embonini yokugaya amaphepha, okuvumela ukuthi imikhiqizo yephepha eyengeziwe ikhiqizwe ngesikhathi esifushane.
Okokugcina,ama-cranes angaphezuluziyimishini eqinile futhi eqinile.Angakwazi ukumelana nezindawo zokusebenza ezinzima futhi angasetshenziswa ukuphakamisa nokuthutha izinto ezinesisindo samathani amaningana.Ama-cranes angaphinde asebenze ngokuqhubekayo ngaphandle kokushisisa ngokweqile noma ukuphuka - isici esibalulekile embonini yokugaya iphepha elimahhadlahhadla futhi eliwa.
