Ukongeza kwii-cranes ze-gantry ze-gantry zenjongo-nye ezichazwe ngasentla, i-SEVENCRANE iyila kwaye yakha ii-cranes ze-gantry ezahlukeneyo ze-single-beam ze-industrial applications ezahlukeneyo, kubandakanywa i-rabha yerabha ye-hydraulic-tyre kunye ne-gantry cranes ezisebenza ngombane. Iikhreyini ze-gantry zegirder enye zisetyenziswa ikakhulu kwimigodi, kwimveliso jikelele, ikhonkrithi esele ibekwe ngaphambili, ulwakhiwo, kunye needokhi zokulayishwa zangaphandle kunye neendawo zokugcina iimpahla zokuphatha imisebenzi emikhulu yomthwalo. I-Single-girder gantry crane ngokubanzi ithathwa njengoluhlobo olukhaphukhaphu lwe-gantry crane ngenxa yoyilo lwesakhiwo esinomqadi omnye kuphela, isetyenziswa kakhulu kwiindawo ezivulekileyo ezinje ngeeyadi zemathiriyeli, iindibano zocweyo, iindawo zokugcina izinto zokulayisha kunye nezothutho.
I-Single-girder gantry crane yicrane eqhelekileyo eyenzelwe ukuphatha imathiriyeli ngokubanzi, esoloko isetyenziswa kwiindawo ezingaphandle, kwindawo zokugcina iimpahla, kumazibuko, kumashishini egranite, kumashishini emibhobho yesamente, iiyadi ezivulekileyo, iindawo zokugcina izitya, kunye neendawo zeenqanawa, njl.njl. Nangona kunjalo, akuvumelekanga ukuphatha isinyithi esinyibilikayo, izinto ezinokutsha, okanye eziqhumayo. Ibhokisi yodidi lwe-gantry crane inobungakanani obuphakathi, ikrane yokuhamba ngomkhondo, ixhotyiswe ngokubanzi ngesiphakamisi sombane se-HDMD njengesiphakamisi, kunye nesiphakamisi sombane esinqumla phezu kwe-I-steel esezantsi yebhanti engundoqo, eyenziwe ngepleyiti yentsimbi. , eyenziwe kwisitya sentsimbi, njenge-C-steel, kunye ne-insulating steel plate, kunye ne-I-steel. Ngaphezu koko, iikhreyini zegirder enye ziyasebenza ngaphakathi nangaphandle, njengeworkshop, indawo yokugcina impahla, igaraji, iisayithi zokwakha, kunye namazibuko, njl. Ukuba unezinye iimfuno ezikhethekileyo malunga ne-single girder gantry cranes span, umthamo wokulayisha, okanye umphakamo wokuphakamisa, ungaxelela i-Aicrane ngazo, kwaye siya kukwenzela zona. Iilifti zethu ze-gantry zisebenza kakuhle kwaye zihlala ixesha elide kuba sijonga ngokusondeleyo umgangatho wecrane kwaye sisebenzisa iindawo ezikumgangatho ophezulu ezixhathisayo ukunxitywa. Iikhreyini zethu ezingaphezulu zegirder zixhotyiswe umgangatho kunye nemithwalo ye-swivel ekhaphukhaphu kwishishini, kunye neejacks ezisezantsi ezixhotyiswe ngeedrive eziguquguqukayo kuzo zombini iihoists kunye neeswivels. Ekubeni ii-cranes ze-single-girder zifuna kuphela umqadi omnye wenkxaso, ezi nkqubo ngokubanzi zinobunzima obungaphantsi bokufa, oku kuthetha ukuba banokuthatha inzuzo kwiinkqubo zomkhondo ezikhaphukhaphu kwaye baqhagamshele kwizakhiwo zenkxaso ezikhoyo.
Xa ziyilwe ngokuchanekileyo, zinokwandisa imisebenzi yemihla ngemihla kwaye ziyisisombululo esipheleleyo sezixhobo kunye nemisebenzi enendawo ephantsi yomgangatho kunye ne-overhead efuna i-crane-to-medium-duty-duty crane. Iikhreyini ze-double girder trestle cranes zikwasetyenziswa ngaphakathi okanye ngaphandle, nokuba kukwiibhulorho okanye kubume begantry, kwaye ziqhele ukusetyenziswa kwimigodi, intsimbi kunye nentsimbi, iiyadi zikaloliwe, kunye namazibuko aselwandle. Iikhreyini zebhulorho ziza kuqwalaselo olwahlukileyo, kwaye zinokuqulatha nokuba yimiqadi enye okanye emibini - edla ngokubizwa ngokuba yi-single-girder okanye i-double-girder design. Ngokungafaniyo ne-crane eyodwa yegirder overhead, umqadi wayo oyintloko uxhaswa yimilenze, eyenza ifane nesakhiwo se-gantry.A
