Ama-cranes ahlanganisa kabili ngokuvamile asetshenziselwa ukuphatha imithwalo esindayo kanye nezinhlelo zokusebenza ezidinga ukuma okunembayo kwezinto.
Izici zei-double girder overhead crane:
Izindlela zokuphakamisa nokugijima ziklanywe ngendlela efanayo ukuze kuqinisekiswe ukunemba nokushintshana kwengxenye ngayinye, enezixhumanisi zokudlulisela ezimbalwa, ukusebenza kahle okuphezulu, izinga lokuhluleka eliphansi, kanye nokuhlangana okusheshayo.
Isakhiwo esisindayo siqinile, sihlala isikhathi eside, futhi sinamandla amakhulu okuthwala, angakwazi ukuzivumelanisa nezimo zokusebenza ezinzima.
Ihuku kanye nendlela yokuphakamisa ixhunywe kalula ukuze ishintshwe ngokushesha.
Wonke umshini ulawula isivinini esishintshashintshayo, onokuqala okushelelayo kanye nokubhuleka, uphephile futhi kulula ukuwusebenzisa.
Kusetshenziswa izingxenye ezisezingeni eliphezulu, ezinokugcinwa okuphansi nempilo ende yesevisi.
