I-double girder gantry cranes lukhetho oludumileyo kwimisebenzi yokunyusa enzima efuna umthamo ongaphezulu kunye nobude obude kune-single girder gantry cranes. Ziyilwe kwaye zenziwe ngezakhiwo zetsimbi ezomeleleyo kwaye zifumaneka kuluhlu lwezakhono zokuphakamisa, ukusuka kwi-5 ukuya kwiitoni ezingama-600.
Iimpawu ze-double girder gantry cranes ziquka:
1. Ukwakhiwa kwentsimbi eqinile kunye neyomeleleyo yokusebenza okuthembekileyo kunye nexesha elide.
2.Ubude obunokwenziwa ngokwezifiso kunye nobude bokuhlangabezana neemfuno ezithile zokuphakamisa.
3. Iimpawu zokhuseleko oluphezulu, ezifana nokukhusela umthwalo ogqithisileyo kunye neebhuleki ezingxamisekileyo.
I-4.I-Smooth kunye nokusebenza ngokufanelekileyo kunye nokunyusa kunye nokunciphisa ingxolo encinci.
5. Kulula ukusebenzisa ulawulo lwentshukumo echanekileyo.
6. Iimfuno zokugcinwa okuphantsi kokunciphisa ixesha lokuphumla kunye neendleko zokusebenza.
7. Ifumaneka kwiimpawu ezahlukeneyo, ezifana ne-gantry epheleleyo okanye ephakathi, ngokuxhomekeke kwisicelo esithile.
I-double girder gantry cranes ilungele uluhlu lwamashishini, kubandakanywa ukuthunyelwa, ukwakhiwa, kunye nokuvelisa, kwaye ifanelekile ukuphakamisa iimpahla ezinzima kunye nezinto eziphathekayo kwiindawo zangaphandle okanye zangaphakathi.
Iicranes zegirder gantry eziphindwe kabini ziikhreyini ezinomsebenzi onzima ezenzelwe ukuphakamisa kunye nokuhambisa imithwalo enzima kakhulu. Ngokuqhelekileyo banobude obungaphezulu kwe-35m kwaye banokuthwala imithwalo ukuya kwiitoni ezingama-600. Ezi cranes ziqhele ukusetyenziswa kumashishini afana nentsimbi, ukwakha iinqanawa, kunye nokuveliswa koomatshini abakhulu, kunye nakwiindawo zeenqanawa kunye namazibuko okulayisha kunye nokothula iinqanawa zemithwalo.
Uyilo lwe-double girder gantry cranes lukhethekileyo, kwaye ukuveliswa kwazo kufuna umgangatho ophezulu wobuchule kunye nobuchule. Amabhanti amabini adityaniswe ngetroli ehamba ngobude bexesha, evumela i-crane ukuba ihambise umthwalo kwiindlela zombini ezithe tye kunye nezithe nkqo. I-crane inokuxhotyiswa ngoluhlu lweendlela zokuphakamisa, ezinje nge-electromagnets, iihuku, kunye nokubamba, ukuze zilungele izicelo ezahlukeneyo.
Isishwankathelo, i-double girder gantry cranes sisixhobo esithembekileyo nesisebenzayo sokuhambisa imithwalo enzima kwiindawo zoshishino, izibuko, kunye neendawo zeenqanawa. Ngoyilo olufanelekileyo kunye nokuveliswa, ezi cranes zinokubonelela ngeminyaka yenkonzo esebenzayo.
I-double girder gantry crane yenzelwe ukuphakamisa kunye nokuhambisa imithwalo enzima kwiindawo ezahlukeneyo. Uyilo kunye nokuveliswa kwee-double girder gantry cranes kubandakanya iinkqubo ezininzi eziqinisekisa ukuthembeka kwazo, ukhuseleko kunye nokusebenza kakuhle.
Isinyathelo sokuqala sokuyila kunye nokuvelisa ezi cranes kubandakanya ukukhetha izinto ezifanelekileyo kunye namacandelo. Intsimbi esetyenziswe kwinkqubo yokuvelisa kufuneka ibe namandla aphezulu kunye nokumelana nokugqwesa okugqwesileyo ukumelana neemeko zokusebenza ezinzima. Itekhnoloji ye-welding ephezulu isetyenziselwa ukudibanisa iindawo ezahlukeneyo zekhreyini.
Inkqubo yoyilo encediswa yikhompyuter isetyenziselwa ukwenza imodeli echanekileyo ye-3D yecrane, esetyenziselwa ukukhulisa ubume kunye nokunciphisa ubunzima becrane ngelixa igcina amandla kunye nokuqina kwayo. Inkqubo yombane ye-gantry crane yenzelwe ukuqinisekisa ukusebenza kakuhle, ukuthembeka kunye nokhuseleko.
Ukwenziwa kwemveliso kwenzeka kwiindibano zocweyo ezikhethekileyo ezineenkqubo ezingqongqo zolawulo lomgangatho. Iimveliso zokugqibela zivavanywa ngokungqongqo kunye nokuhlolwa ngaphambi kokuhanjiswa kumthengi. Le gantry crane sisixhobo esithembeke kakhulu nesisebenzayo esinokuphakamisa nokuhambisa imithwalo enzima ngokulula.
