Iikhreyini zebhulorho ezihamba phezuluube nomzila kaloliwe omiselweyo okanye inkqubo yomzila efakwe phezu komgaqo weenqwelo-moya ngamnye, evumela iilori eziphelayo ukuba zithwale ibhulorho kunye nekhreyini kumphezulu wendlela yeenqwelo-moya. Iikhreyini ezihamba phezulu zinokuqwalaselwa njenge-single-girder okanye i-double-girder bridge designs.Ukubaleka okuphezulu senye umbhinqoiikhreyini sebenzisa iitroli eziphantsi kunye neehoists, ngelixa i-double-girder designs ngokuqhelekileyo zisebenzisa iitroli ezihamba phezulu kunye ne-hoists. Ezi ntlobo ze-cranes ezingaphezulu zixhaswa yizakhiwo zokwakha okanye iikholamu zenkxaso yendlela yeenqwelo-moya kwaye zilungele ukuhambisa imithwalo enzima kakhulu.
Ukuqhuba okuphezulungaphezuluiikhreyinizisisombululo esifanelekileyo kwizakhiwo zoshishino ezine-headroom encinci. Ukubaleka kwiireyile ezibekwe phezu komqadi wendlela yeenqwelo-moya, iikhreyini ezibaleka phezulu zifumana umphakamo owongezelelekileyo ngaphezu koko kunokwenzeka ngecrane ejingayo. Iikhreyini ezihamba phezulu zidla ngokuba nkulu kunaphantsi kweekhreyini ezibalekayo, njengoko zinokwakhelwa amandla aphezulu kwaye zinokuthatha indawo ezibanzi.. Iikhreyini ezihamba phezulu zidla ngokuba nkulu zinamandla okuphakamisa, kwiitoni ezili-10 nangaphezulu. Bona'kwakhona lula ukufaka kunye nenkonzo.
Iinkqubo ezihamba phezulu zifuna uhlolo oluthe kratya lolungelelwaniso lukaloliwe kunye nolungelelwaniso oluthe kratya lukaloliwe.Ngenxa yokuba i-crane ixhaswa kwii-rails phezu kwe-runway beam, akukho zixhobo zomthwalo omisiweyo, ukwenza ukufakela kunye nokulungiswa kwexesha elizayo okanye ukulungiswa kulula kwaye kuchitha ixesha elincinci kune-crane yokusebenza.
Ngethuba lobomi bayo benkonzo, umzila okanye inkqubo kaloliwe apho ibhulorho ihamba khona inokufuna ukujonga ukulungelelaniswa okanye ukulandelela imiba ngokuphindaphindiweyo kune-crane yokusebenza. Ngethamsanqa, ukulungiswa kunye nokutshekishwa kolungelelwaniso kulula ukwenza kwaye kufuna ixesha lokuphumla elingaphantsi kune-crane yokusebenza.
I-SEVENCRANE inokukunceda ukuba uqikelelephezulu ibhulorho crane ebalekayoiinkqubo zokusebenza kwakho-ngokusekwe kwiinkcukacha zoncedo lwakho kunye neemfuno ezizodwa zeshishini lakho kunye neenkqubo. I-SEVENCRANE inikezela ngezisombululo ezipheleleyo-kubandakanywa izixhobo, ukuhlolwa kunye nokugcinwa, kunye noqeqesho lwabaqhubi kunye nabasebenzi benkonzo.
