Yintoni i-launching gantry?

Kwihlabathi lokwakha, ukusebenza kakuhle nokuchaneka kubalulekile. Isidingo sezisombululo ezintsha ezilungelelanisa inkqubo yokwakha siye sakhokelela ekuphuhlisweni koomatshini nezixhobo eziphambili. Enye yezinto ezintsha ezisandul’ ukuveliswa yayiyi-launch gantry crane, eyaziwa ngokuba yi-bridge launch crane. Le nxalenye yobunjineli emangalisayo iguqula indlela ezenziwa ngayo iiprojekthi zokwakha iibhulorho, inika ukusebenza kakuhle nokhuseleko olungenakuthelekiswa nanto. Kodwa yintoni kanye kanye i-launch gantry, kwaye iyinceda njani imboni yokwakha?

I-Launch gantry crane sisixhobo esikhethekileyo esenzelwe ukwakha iibhulorho, ii-viaducts kunye nezinye izakhiwo eziphakamileyo. Isetyenziselwa ukuphakamisa nokubeka iibhulorho zekhonkrithi okanye zentsimbi ezicwangcisiweyo ukuze kuhlanganiswe idekhi ngokukhawuleza. Ii-gantry crane zihlala zinesakhelo esomeleleyo esixhaswa zii-outriggers ezijikeleza ubude bebhulorho. Ixhotyiswe ngendlela yokuphakamisa ngokuchanekileyo enokuphakamisa ii-girders zebhulorho ezinzima ngokuchanekileyo nangokuchanekileyo.

Umsebenzi ophambili we-launch gantry crane kukwenza kube lula ukuhamba ngokuthe tye nangokuthe nkqo kwe-bridge girders ngexesha lenkqubo yokwakha. Oku kufezekiswa ngokudityaniswa kweenkqubo ze-hydraulic, mechanical kunye ne-elektroniki ezisebenzisana ukuqinisekisa ukusebenza okugudileyo nokulawulwayo. Amandla e-crane okulawula ngokuchanekileyo izinto ezinzima ayenza ibe sisixhobo esibalulekileyo kwiiprojekthi zokwakha i-bridge, nto leyo enciphisa kakhulu ixesha kunye nomsebenzi ofunekayo ukugqiba isakhiwo.

Enye yezona nzuzo ziphambili zokusebenzisa i-crane ye-gantry crane eqalayo kukukwazi ukukhawulezisa ishedyuli yokwakha. Ngokubeka ibhulorho esele yenziwe ngaphambili ngokukhawuleza, ii-crane zinokuhlanganisa ngokukhawuleza idekhi, zinciphise ukuphazamiseka kwezithuthi kwaye zinciphise ixesha leprojekthi iyonke. Oku akupheleli nje ekuncedeni inkampani yokwakha ekongeni ixesha kunye neendleko, kodwa kukwanegalelo elihle kuluntu olungqongileyo ngokunciphisa iingxaki ezinxulumene nokwakha.

Ukhuseleko lolunye umba obalulekileyo wokwakhiwa kwebhulorho, kwaye ukusetyenziswa kweekhreyini zokuphakamisa ii-gantry kuphucula kakhulu ukhuseleko kwiindawo zokwakha. Ngokunciphisa isidingo sokuphatha ngesandla ii-girders zebhulorho ezinzima, umngcipheko weengozi kunye nokwenzakala ungancitshiswa kakhulu. Iinkqubo zolawulo eziphucukileyo zekhreyini kunye neempawu zokhuseleko ziqinisekisa ukuba ukuphakamisa nokubeka imiqadi kwenziwa ngokuchanekileyo nangokuhambelana nemigaqo yokhuseleko.

Ukuguquguquka kweekhreyini ze-gantry zokuqalisa kuzenza zibe zizinto ezixabisekileyo kwiiprojekthi zokwakha iibhulorho. Ubuchule bayo bokwamkela iintlobo ngeentlobo zoyilo lweebhulorho kunye nolwakhiwo, kunye nokukwazi ukuphatha iintlobo ezahlukeneyo zeebhrorho, kwenza ukuba ibe sisisombululo esiguquguqukayo nesiguquguqukayo kwiimfuno ezahlukeneyo zokwakha. Nokuba yi-overpass yendlela enkulu, ibhulorho kaloliwe okanye indlela yokuhamba, iikhreyini ze-gantry zokuqalisa zinokwenziwa ngokwezifiso kwiimfuno ezithile zeprojekthi.

Ngamafutshane, ukuqalisa ii-gantry cranes kubonisa inkqubela phambili ebalulekileyo kubuchwepheshe bokwakha iibhulorho, nto leyo enika ukusebenza kakuhle okungenakuthelekiswa nanto, ukhuseleko kunye nokuguquguquka. Amandla ayo okukhawulezisa inkqubo yokwakha, ukuphucula imigangatho yokhuseleko kunye nokuziqhelanisa neemfuno ezahlukeneyo zeprojekthi kuyenza ibe sisixhobo esibalulekileyo kwiiprojekthi zokwakha zanamhlanje. Njengoko ishishini lokwakha liqhubeka nokukhula, ukungeniswa kwee-gantry cranes kubonisa amandla okuvelisa izinto ezintsha ukuqhuba inkqubela phambili kunye nokutshintsha indlela esakha ngayo iziseko zophuhliso zexesha elizayo.
