Iikhreyini zokunyusela ngaphezulu kwentloko ezimbini zineebhanti ezimbini zebhulorho ezincanyathiselwe kwimizila kwaye zihlala zixhotyiswa ngeentambo zombane ezityibilikayo zeefestile zentambo, kodwa zinokufakelwa amatsheyini ombane atyibilikayo ngokuxhomekeke kwisicelo. Ii-portals ziqukethe iingoma ezimbini ezingaphezulu, ibhuloho, engumqadi othe tye ohamba ngeendlela, i-winch kunye ne-trolley. Iikhreyini ezingaphezulu ngokuqhelekileyo ziquka iwintshi yetroli engaphezulu ehamba phezu kwemiqadi emibini yebhulorho kwiseti yayo yamavili ukwandisa isithuba phantsi kwekhreyini; ikwabizwa ngokuba yi-overhead crane.
I-SEVENCRANE i-double hoist overhead crane inoyilo olwahlukeneyo, olufana ne-double hoist overhead crane kunye ne-double hoist crane. Ikhreyini yokunyusela phezulu kabini idla ngokuyilelwe ukusetyenziswa ngaphakathi, njengendawo yokusebenzela, indawo yokugcina impahla yokuphatha kunye nokunyuswa kwezinto ezincinci ukuya kweziphakathi.
Ngokuqhelekileyo, xa ukhetha okanye usebenzisa i-double hoist overhead crane, ngokuqhelekileyo kuqwalaselwa kunye ne-electric hoist , kwaye kwezinye iimeko ezikhethekileyo ezifuna ukuphakamisa i-hoist yombane emibini kunye, i-crane ye-double hoist kufuneka ixhotyiswe ngamabini amabini ombane. I-double hoist crane yi-crane eyodwa yegirder ene-hoist ezimbini zombane zokuphatha izinto ezifanelekileyo. Ikhreyini yombane ye-SEVENCRANE-LH yokunyusela ngaphezulu isebenzisa intambo yocingo emileyo njengesixhobo sokunyusela, exhonywe kwitroli esebenza kumbindi weendlela ezimbini.
Iikhreyini zokunyusela phezulu kabini zixhotyiswe ngezixhobo zokuxhoma zokunyusela kunye nokuhambisa imithwalo eyahlukeneyo okanye izixhobo. Ngeempawu zesakhiwo esihlangeneyo, ubunzima obuncinane bokufa, uxinzelelo lwevili eliphantsi kunye nokusabalalisa umthwalo, i-European Double Hoist Overhead Crane inokunciphisa kakhulu iindleko zokwakha kunye nokufudumeza, kunye nokwenza lula ukugcinwa. Iiklasi zenkonzo eziphakamileyo kunye nezicelo ezikhethekileyo ezifana ne-mold tipping kunye ne-double lift systems zifaneleke kakhulu kwii-cranes ze-double girder.
Ikhreyini yokunyusela phezu kwentloko ephindwe kabini inokuxhotyiswa ngephedi yokunyusela ngekhonkco lombane, iphedi yokudlulisa ezimeleyo okanye ulawulo lwerediyo. Iikrane ezingaphezulu ezivela kwi-SEVENCRANE Cranes & Components ziza kwiindidi ezimbini, i-box girder kunye necandelo eliqhelekileyo, kwaye ziza kunye ne-integral hoisting mechanism, ngokuqhelekileyo i-winch okanye i-winch evulekile.
