Ama-crane angaphezulu ayimishini ebalulekile esetshenziswa ezimbonini eziningi, okuhlanganisa ukwakhiwa, ukukhiqiza, kanye nezokuthutha. Asetshenziselwa ukuphakamisa imithwalo esindayo futhi atholakala ngezinhlobo ezimbili: enziwe ngokwezifiso kanye nejwayelekile.
Amakhreni angaphezulu enziwe ngokwezifiso aklanyelwe ukuhlangabezana nezidingo ezithile zomkhakha othile, inkampani noma iphrojekthi. Akhiwe ngokwezidingo eziqondile zamakhasimende, kucatshangelwa izici ezifana nomthamo womthwalo, ubude, ukuphakama, kanye nendawo ezungezile. Isibonelo, ikhreni engenhla esetshenziswa esitshalweni sokukhiqiza insimbi ingakhiwa ngendlela ehlukile kuneyo esetshenziswa endaweni yokugcina impahla noma egcekeni lokuthumela impahla. Ngakho-ke amakhreni angaphezulu enziwe ngokwezifiso anikeza ukuguquguquka okukhulu ngokwedizayini, ukusebenza, kanye nokusebenza kahle.
Ngakolunye uhlangothi, ama-overhead cranes ajwayelekile aklanyelwe ukuhlangabezana nezidingo ezijwayelekile futhi awakhelwe izimboni noma amaphrojekthi athile. Afika ngobukhulu obuhlukene, amandla okulayisha, kanye nokucushwa futhi atholakala kalula ukuze athengwe noma aqashwe. Ngakho-ke ayabiza kancane kune-overhead cranes ezenziwe ngokwezifiso futhi angashintshwa kalula noma athuthukiswe.
Kokubili okwenziwe ngokwezifiso futhi okujwayelekileamakhreni aphezuluzinezinzuzo zazo kuye ngezidingo zomkhakha noma iphrojekthi. Ama-overhead cranes enziwe ngokwezifiso afanele izimboni ezinezidingo ezithile ama-crane ajwayelekile angenakuzihlangabezana nazo. Anikeza ukusebenza kahle okukhulu, ukuphepha, kanye nokukhiqiza. Ama-overhead cranes ajwayelekile afaneleka kakhulu ezimbonini ezincane noma lezo ezinezinhlelo zokusebenza ezingabizi kakhulu.
Ekuphetheni, ama-crane angaphezulu ayimishini ebalulekile edlala indima ebalulekile ezimbonini eziningi. Ama-crane enziwe ngokwezifiso kanye najwayelekile anikeza izinzuzo eziyingqayizivele futhi ayisengezo esibalulekile kunoma yiliphi ibhizinisi. Ngakho-ke izimboni nezinkampani kufanele zihlole izidingo zazo ngaphambi kokunquma uhlobo lwe-crane okufanele zitshale kuyo imali.
