Amakhreni angaphezulu, obeye aziwe njengoamakhreni ebhuloho, ziyimishini ebalulekile yokuphakamisa nokuhambisa izinto ezisindayo ezimbonini ezahlukene. Lawa ma-crane asebenza ngezindlela ezahlukene, kuye ngomklamo wawo kanye nezidingo ezithile zokusetshenziswa kwawo.
Enye indlela evamile yokunika amandla ama-crane angaphezulu iwukusebenzisa ugesi. Ama-crane kagesi anezinjini zikagesi eziqhuba i-crane ohlelweni lwendlela ephakeme. Injini ivame ukuxhunywa emthonjeni wamandla ngezintambo noma imigoqo yokuqondisa, okunikeza amandla kagesi adingekayo ukuze kusetshenziswe i-crane. Ama-crane kagesi angaphezulu adumile ngenxa yokusebenza kwawo kahle, ukulawula okunembile kanye nokulula kokusebenza.
Kwezinye izimo, ama-crane aphezulu asebenza ngezinhlelo ze-hydraulic. Ama-crane aphezulu e-hydraulic asebenzisa amandla e-hydraulic ukusebenzisa izindlela zokuphakamisa nokuhambisa. Amaphampu e-hydraulic asetshenziselwa ukukhiqiza ingcindezi, edluliselwa ngamasilinda e-hydraulic ukuze iphakamise futhi yehlise imithwalo. Nakuba ama-crane aphezulu e-hydraulic engavamile kakhulu kune-crane kagesi, futhi ayisinqumo esihle sezinhlelo zokusebenza ezidinga amandla aphezulu okuphakamisa kanye nemisebenzi enzima.
Enye indlela yokunika amandla i-overhead crane ngokusebenzisa umoya noma uhlelo lwe-pneumatic. Ama-pneumatic overhead crane asebenzisa umoya ocindezelwe ukuze asebenze imisebenzi yokuphakamisa nokuhambisa. Ama-pneumatic crane afanele ukusetshenziswa ezindaweni lapho amandla kagesi noma e-hydraulic engase angenzeki noma angaphephile, njengezindawo eziyingozi noma eziqhumayo.
Ngaphezu kwalokho, amanye ama-crane angaphezulu asebenza ngokuhlanganiswa kwalezi zindlela, njengezinhlelo ze-electro-hydraulic noma ze-pneumatic-electric, ukuze kuzuze izinzuzo zomthombo ngamunye wamandla.
Ngamafuphi, ama-crane aphezulu angasebenza ngezindlela ezahlukahlukene, okuhlanganisa izinhlelo zikagesi, ze-hydraulic kanye neze-pneumatic, noma inhlanganisela yalezi zindlela. Ukukhetha umthombo wamandla kuncike ezintweni ezifana nomthamo wokuphakamisa, izidingo zokusebenza kanye nokucatshangelwa kwemvelo. Ukuqonda ukuthi ama-crane aphezulu asebenza kanjani kubalulekile ekukhetheni i-crane efaneleke kakhulu yesicelo esithile sezimboni.
