I-Mobile gantry crane yenziwe ngokusisiseko ngamabhanti amabini, iindlela zokuhamba, iindlela zokunyusa, kunye neendawo zombane. Umthamo wokuphakamisa we-gantry crane inokuba ngamakhulu eetoni, ngoko ke oku luhlobo lwe-gantry crane enzima. Kukho olunye uhlobo lwe-gantry crane, uhlobo lwaseYurophu lwe-double-girder gantry cranes. Yamkele ingqikelelo yobunzima bokukhanya, uxinzelelo oluphantsi kumavili, indawo encinci yokuvala, ukusebenza okuthembekileyo, kunye nesakhiwo esibambeneyo.
I-Mobile gantry crane ikwahlala isetyenziswa emigodini, kwimizila yentsimbi kunye nentsimbi, iiyadi zikaloliwe, kunye namazibuko aselwandle. Izuza kuyilo lwegirder oluphindwe kabini olunamandla aphezulu, ispans ezinkulu, okanye ukuphakama okuphezulu. Iikhreyini ezinegila ephindwe kabini ngokuqhelekileyo zifuna ukukhutshwa okukhulu ngaphezu kweekhreyini zomphakamo womgangatho wokuphakama, njengoko iilori zokuphakamisa zinqumla ngaphezu kweebhanti kwibhulorho yeekhreyini. Kuba iikhreyini ze-single-girder zifuna kuphela umqa wendlela yeenqwelo-moya enye, ezi nkqubo zinobunzima obusezantsi, okuthetha ukuba zinokusebenzisa iindlela zeenqwelo-moya ezinobunzima obulula kwaye zincamathele kwizakhiwo ezikhoyo ezixhasayo, ezingakwaziyo ukwenza umsebenzi onzima njenge-double girder mobile gantry crane.
Iindidi ze-gantry crane ezihambayo zikwafanelekile ukwakhiwa kweebhloko zekhonkrithi, iibhanti zentsimbi enzima kakhulu, kunye nokulayishwa kwamaplanga. I-double girder gantry crane ifumaneka ngezitayile ezibini, Uhlobo kunye nohlobo lwe-U, kwaye zixhotyiswe ngomatshini wokuphakamisa owakhelwe ngaphakathi, oqhele ukuba yi-hoist evulekileyo okanye iwintshi.
I-crane ye-double girder gantry inokubonelelwa kwimisebenzi eyahlukeneyo yokusebenza, izakhono zayo ezilinganisiweyo zisekelwe kwiimfuno zabathengi. Thina iinjineli ze-SEVENCRANE kwaye sakha izisombululo zesiko ukusuka kuqoqosho, iikrane ezikhaphukhaphu ukuya kumthamo ophezulu, umthwalo onzima, i-welded girder-boxed cyclops.
