I-crane ephezulu ehamba phezulu inomzila kaloliwe osisigxina okanye inkqubo yeengoma ezifakwe phezulu kwi-beam nganye kwindlela yeenqwelo-moya - oku kuvumela iilori eziphelayo ukuba zithuthe iibhulorho kunye nokunyuswa ngaphaya kwenkqubo yendlela yeenqwelo-moya. Iikhreyini ezihamba phezulu zibaleka kwimizila engaphezulu kwemiqadi yomgaqo weenqwelo-moya, ngaloo ndlela ibonelela ngobude obukhulu kwizakhiwo ezithintelwe bubude.
Top Ukubaleka Overhead Crane ukhetho olugqibeleleyo kwinkonzo medium-heavy, kwaye ziqhele ukusetyenziswa kwizityalo zentsimbi, foundries, iivenkile oomatshini enzima, ipulp Mills, izityalo ukugalela, etc. A Top Ukubaleka Overhead Crane ibonelela ngobude obuphezulu kunokwenzeka kwisakhiwo, njengoko ii-hoist kunye neetroli zinqumla phezulu kwebhanti. Ngaphantsi kwee-cranes eziqhubayo zibonelela ngokuguquguquka, ukukwazi, kunye nezisombululo ze-ergonomic, ngelixa iisistim ze-crane ezihamba phezulu zibonelela ngeenzuzo zokuphakamisa okuphezulu kunye nendawo enkulu ngaphezulu.
Iikhreyini ezihamba phezulu ezisebenza phezulu ziyilelwe ukunqumla phezu komgaqo weenqwelo-moya, oxhaswa mhlawumbi ukusuka kwiintsika zesakhiwo okanye kwiintsika zesakhiwo. Iinjineli ze-SEVENVRANE kwaye zakha zonke iintlobo zokucwangciswa kwe-crane yebhulorho ephezulu kubandakanywa (kodwa kungaphelelanga) i-crane ye-double girder okanye i-crane-girder crane, enokuthi ifakwe njenge-top running or bottom running solutions. Iikhreyini ezihamba phezulu zinokuthi ziqwalaselwe njengoyilo lwebhulorho yebhanti enye okanye kabini kwaye ilungele ukuhambisa imithwalo enzima kakhulu.
Iikhreyini ezihamba phezulu zihamba phezu kwebhulorho, kunye neekhreyini ezihamba phezulu zibuyela umva. Iikhreyini ezixhonywe phezulu zidla ngokusetyenziswa kwiinkonzo ezikhaphukhaphu, njengemveliso ekhaphukhaphu, iintambo zokudityaniswa ezikhaphukhaphu, njl.njl., ngelixa iikhreyini ezihamba phezulu ngaphezulu kwebhulorho ziqhele ukusetyenziswa kwiinkonzo ezinzima, njengeziseko, izityalo ezinkulu zokuvelisa, kunye nezityalo zokutywina.
