Yeyiphi i-crane esetyenziselwa ukuqalisa i-girder?

Kwicandelo lokwakha nobunjineli, ukuphathwa kakuhle nangokukhuselekileyo kwezinto ezinzima kubaluleke kakhulu. Enye yezona zinto zibalulekileyo ekwakhiweni kweebhulorho kunye neeprojekthi zeziseko zophuhliso ezinkulu kukuqaliswa kweegirders. Ngenxa yesi sizathu, kusetyenziswa isixhobo esikhethekileyo esaziwa ngokuba yi-launcher girder crane.

I-girder crane yokuqalisayenzelwe ngokukodwa ukuphakamisa nokubeka ii-girders ezinkulu, eziyinxalenye ebalulekileyo ekwakhiweni kweebhulorho kunye neendawo zokudlula ngaphezulu. Ezi cranes zenzelwe ukujongana nemingeni eyahlukileyo enxulumene nokuqaliswa kwe-girder, kubandakanya imfuneko yokubekwa ngokuchanekileyo kunye nokukwazi ukusebenza kwiindawo ezixineneyo. Uyilo lwe-launcher girder crane ludla ngokuba nokufikelela okude kunye nomthamo wokuphakamisa oqinileyo, okuvumela ukuba ikwazi ukuhambisa ii-girders ezinzima endaweni yazo ngokulula.

Ukusebenza kwekreyini yegirder yokuqalisa kubandakanya amanyathelo aliqela abalulekileyo. Okokuqala, ikreyini ibekwa kwindawo yokwakha, idla ngokuba kwiqonga okanye kwitreyini yexeshana. Yakuba ikwindawo, indlela yokuphakamisa ikreyini isetyenziselwa ukuphakamisa igreyini kwindawo yayo yokuthutha. Umqhubi wekreyini kufuneka alawule ngononophelo intshukumo yegreyini ukuqinisekisa ukuba ihambelana ngokuchanekileyo nezakhiwo ezixhasayo. Oku kufuna inqanaba eliphezulu lesakhono kunye nokulungelelaniswa, njengoko naluphi na ulungelelwaniso olungalunganga lunokukhokelela ekulibazisekeni okukhulu nakwiingozi zokhuseleko.

Ukongeza kwiikreyini zegirder zesiqalisi sendabuko, kukwakho notshintsho olufana nesiqalisi se-cantilever, esiluncedo ngakumbi ekuqaliseni iigirders phezu kwezakhiwo okanye imiqobo ekhoyo. Ezi kreyini zixhotyiswe ngobuchwepheshe obuphambili, kuquka iinkqubo zolawulo olukude kunye neempawu ezenzekelayo, ukuphucula ukhuseleko kunye nokusebenza kakuhle ngexesha lenkqubo yokuqalisa.

Ukuqukumbela, i-launcher girder crane sisixhobo esibalulekileyo kushishino lokwakha, esenzelwe ngokukodwa ukuqaliswa ngokukhuselekileyo nangokufanelekileyo kwee-girders. Iimpawu zayo ezikhethekileyo kunye nobuchule ziyenza ibe lukhetho oluthandwayo kwiinjineli kunye nabakhi ababandakanyeka kwiiprojekthi ezinkulu zeziseko zophuhliso.
