Iikhreyini ezingaphezulu, kwaziwa njengeiikhreyini zebhulorho, zixhobo eziyimfuneko zokuphakamisa kunye nokuhambisa izinto ezinzima kumashishini ahlukeneyo.Ezi cranes zinikwe amandla ngeendlela ezahlukeneyo, kuxhomekeke kuyilo lwazo kunye neemfuno ezithile zokusetyenziswa kwazo.
Enye indlela eqhelekileyo yokunika amandla iikhreyini ezingaphezulu kungombane.Iikhreyini zeebhulorho zombane zixhotyiswe ngeenjini zombane eziqhuba ikhreyini ecaleni kwendlela yeenqwelo-moya ephakamileyo.I-motor idla ngokudityaniswa kumthombo wamandla ngeentambo okanye ii-conductor bar, inika amandla ombane afunekayo ukuze kusebenze ikhreyini.Iikhreyini ezingaphezulu kombane zithandwa ngokusebenza kwazo okuphezulu, ulawulo oluchanekileyo kunye nokusebenza ngokulula.
Kwezinye iimeko, iikhreyini ezingaphezulu zinikwa amandla ziinkqubo zamanzi.Iikhreyini zeHydraulic ezingaphezulu zisebenzisa amandla omoya osebenza ngoxinzelelo olukhulu olwenziwa ngamanzi ukuze kusetyenziswe iindlela zokuphakamisa nokuhambisa.Iimpompo ze-hydraulic zisetyenziselwa ukuvelisa uxinzelelo, oluthi ke luhanjiswe ngeesilinda ze-hydraulic ukuphakamisa kunye nokunciphisa imithwalo.Nangona i-hydraulic overhead cranes ingaxhaphakanga kuneekhreyini zombane, zikwalukhetho olufanelekileyo lwezicelo ezifuna umthamo ophakamileyo wokuphakamisa kunye nemisebenzi enzima.
Enye indlela yokunika amandla i-crane ephezulu kumoya okanye inkqubo yomoya.Iikhreyini ze-pneumatic overhead zisebenzisa umoya oxinzelelweyo ukuze ziqhube imisebenzi yokunyusa kunye nokuhambisa.Iikhreyini ze-pneumatic zilungele ukusetyenziswa kwindawo apho amandla ombane okanye olwenziwa ngamanzi angenakwenzeka okanye akhuselekile, njengeendawo ezinobungozi okanye eziqhumayo.
Ukongeza, ezinye iikhreyini ezingaphezulu zinikwa amandla yindibaniselwano yezi ndlela, ezinje nge-electro-hydraulic okanye i-pneumatic-electric systems, ukuthatha inzuzo yomthombo wamandla ngamnye.
Isishwankathelo, ii-cranes eziphezulu zinokuthi zinikwe amandla ngeendlela ezahlukeneyo, kubandakanywa umbane, i-hydraulic kunye ne-pneumatic systems, okanye ukudibanisa kwezi ndlela.Ukukhethwa komthombo wamandla kuxhomekeke kwizinto ezifana nokuphakamisa umthamo, iimfuno zokusebenza kunye nokuqwalaselwa kokusingqongileyo.Ukuqonda ukuba iikhreyini ezingaphezulu zisebenza njani kubalulekile ekukhetheni eyona crane ifanelekileyo kwisicelo esithile somzi-mveliso.
