Iikhreyini eziphezu komhlaba, kwaziwa njengeiikhreni zebhulorho, zizixhobo ezibalulekileyo zokuphakamisa nokuhambisa izinto ezinzima kumashishini ahlukeneyo. Ezi cranes zisebenza ngeendlela ezahlukeneyo, kuxhomekeke kuyilo lwazo kunye neemfuno ezithile zokusetyenziswa kwazo.
Enye indlela eqhelekileyo yokunika amandla ii-crane eziphezulu kukusebenzisa umbane. Ii-crane zombane ezisebenzisa iibhulorho zixhotyiswe ngee-motor zombane eziqhuba i-crane kwinkqubo yendlela ephakamileyo. I-motor idla ngokuqhagamshelwa kumthombo wamandla ngeentambo okanye ii-conductor bars, nto leyo enika amandla ombane afunekayo ukuze i-crane isebenze. Ii-crane zombane ezisebenzisa ii-overhead zithandwa ngenxa yokusebenza kwazo kakuhle, ulawulo oluchanekileyo kunye nokulula kokusebenza.
Kwezinye iimeko, ii-overhead cranes zisebenza ngeenkqubo ze-hydraulic. Ii-hydraulic overhead cranes zisebenzisa amandla e-hydraulic ukusebenzisa iindlela zokuphakamisa nokuhamba. Iimpompo ze-hydraulic zisetyenziselwa ukuvelisa uxinzelelo, oluthi emva koko ludluliselwe ngee-hydraulic cylinders ukuze luphakamise kwaye lunciphise imithwalo. Nangona ii-hydraulic overhead cranes zingaqhelekanga kunee-electric cranes, zikwalukhetho olufanelekileyo kwizicelo ezifuna amandla aphezulu okuphakamisa kunye nemisebenzi enzima.
Enye indlela yokunika amandla i-overhead crane kukusebenzisa umoya okanye inkqubo ye-pneumatic. Ii-pneumatic overhead crane zisebenzisa umoya ocinezelweyo ukuqhuba imisebenzi yokuphakamisa nokuhamba. Ii-pneumatic crane zifanelekile ukusetyenziswa kwiindawo apho amandla ombane okanye e-hydraulic asenokungabi lula okanye akhuselekileyo, njengeendawo ezinobungozi okanye eziqhumayo.
Ukongeza, ezinye ii-cranes ezisebenza ngaphezulu zisebenza ngokudibanisa ezi ndlela, njengeenkqubo ze-electro-hydraulic okanye ze-pneumatic-electric, ukuze zisebenzise iingenelo zomthombo ngamnye wamandla.
Ngamafutshane, ii-overhead cranes zinokusetyenziswa ziindlela ezahlukeneyo, kuquka iinkqubo zombane, ii-hydraulic kunye ne-pneumatic, okanye indibaniselwano yezi ndlela. Ukukhetha umthombo wamandla kuxhomekeke kwizinto ezifana nomthamo wokuphakamisa, iimfuno zokusebenza kunye nokuqwalaselwa kwendalo. Ukuqonda indlela ii-overhead cranes ezisetyenziswa ngayo kubalulekile ekukhetheni i-crane efanelekileyo kwisicelo esithile semizi-mveliso.
