I-cranes engaphezulu ingumatshini obalulekileyo kumashishini amaninzi, kubandakanya nomzi mveliso wephepha lephepha. Imithetho yephepha ifuna ukuphakamisa okuchanekileyo kunye nokuhamba kwemithwalo enzima kuyo yonke inkqubo yokuvelisa, kwizinto ezingafunekiyo kwiimveliso ezigqityiweyo. Isixhenxe ngaphezulu kwe-crane ibonelela ngesisombululo sokuphakamisa impumelelo.
Okokuqala,ngaphezulu kwe-cranes engaphezuluNika ukhuseleko olwaphuculweyo, olubaluleke kakhulu kwiziko lemveliso. Ezi cranes zenzelwe ukuphakamisa nokuhambisa izinto ezinzima, ukuqinisekisa ukuba umthwalo uphakanyisiwe ngokukhuselekileyo nangokukhuselekileyo. Ngaphaya koko, ngaphezulu kwe-cranes engaphezulu kweza kuthwala imithwalo emikhulu enokuba nzima okanye ayinakwenzeka ukuba abantu baphakamise, ukunciphisa umngcipheko wokulimala abasebenzi.
Okwesibini, ngaphezulu kwe-cranes engaphezulu kwexabiso eliqhelekileyo, nto leyo ebangela ukuba isetyenziswe kwii-mills zephepha. Uyilo lwe-crane lunokulungelelaniswa ngokulula ukufezekisa iimfuno ezithile zeshishini, kubandakanya ukuphathwa kwezinto ezinzima okanye imveliso ephezulu. Eli nqaku liqinisekisa ukuba iimayile zamaphepha zikwazi ukudibanisa ngokulula iirandi eziphezulu kwiinkqubo zazo zemveliso, ezonyukayo ngokufanelekileyo.
Okwesithathu, ngaphezulu kwe-cranes yentloko ivumela abaqhubi bezityalo ukuba baphathe izixhobo ezifanelekileyo kwaye ngokukhawuleza, ukwanda kwemveliso. Ezi cranes zinokuphakamisa, zishukume okanye zibeke imithwalo enzima okanye imithwalo enzima ngendlela engenamthungo nefanelekileyo, ngesiphazamiso esincinci kwinkqubo yokuphucula. Oku kusebenza kakuhle kuyayonyusa imveliso kwimveliso yephepha, ukuvumela iimveliso zamaphepha okuveliswa ngaphakathi kwisakhelo esifutshane.
Okokugqibela,ngaphezulu kwe-cranes engaphezuluzomatshini oqinileyo nowenzi. Banokukhusela iindawo ezinzima zokusebenza kwaye zinokusetyenziselwa ukuphakamisa kunye nezixhobo zokuhambisa ezixabela iitoni ezininzi. Amaqhinga anokusebenza ngokuqhubekayo ngaphandle kokuhambahamba okanye aqhekeze -yike-eyinto ebalulekileyo kwimveliso ye-Mill yephepha elirhabaxa.
