Iikrane zeGantry zihlelwa ngokwembonakalo yazo kunye nesakhiwo. Uluhlu olupheleleyo lwe-gantry cranes lubandakanya isingeniso kuzo zonke iintlobo ze-gantry cranes. Ukwazi ulwahlulo lwe-gantry cranes luncedo ngakumbi ekuthengeni i-cranes. Iimodeli ezahlukeneyo zeekhreyini zeshishini zihlelwa ngokwahlukileyo.
Ngokwendlela yokwakhiwa kwesakhelo somnyango we-crane, inokwahlulwa ibe yi-gantry cranes kunye ne-cantilever gantry cranes ngokwemilo kunye nesakhiwo socango.
Iikhreyini zeGantryzahlulwa kwakhona zibe:
1. I-gantry crane epheleleyo: umqadi oyintloko awunayo i-overhang, kwaye i-trolley ihamba ngaphakathi kwendawo ephambili.
2. I-Semi-gantry crane: I-outriggers inomahluko wobude, onokuthi umiselwe ngokweemfuno zobunjineli bombutho wesiza.
Iikhrayini zeCantilever gantry zohlulwe kwakhona zibe:
1. I-cantilever gantry crane kabini: Ifom yesakhiwo esiqhelekileyo, uxinzelelo lwesakhiwo kunye nokusetyenziswa ngokufanelekileyo kwendawo yesayithi zombini zinengqiqo.
2. I-crane enye ye-cantilever gantry: Le fomu yesakhiwo ihlala ikhethwa ngenxa yezithintelo zesiza.
Ukwahlula ngokwendlela yokubonakala komqadi ophambili wegantry crane:
1. Ulwahlulo olubanzi lwe-single main girder gantry cranes I-cranes enye yegirder gantry cranes inesakhiwo esilula, kulula ukwenza kunye nokuyifaka, inobunzima obuncinci, kwaye i-girder engundoqo ubukhulu becala isakhelo sebhokisi ye-off-rail. Xa kuthelekiswa ne-double main girder gantry crane, ukuqina okupheleleyo buthathaka. Ngoko ke, le fom ingasetyenziselwa xa amandla okuphakamisa i-Q≤50t kunye ne-S≤35m ye-span. I-Single girder gantry crane door imilenze ifumaneka kuhlobo lwe-L kunye no-C. Uhlobo lwe-L kulula ukulwenza kunye nokulufaka, lunokumelana noxinzelelo oluhle, kwaye lunobunzima obuncinci. Nangona kunjalo, indawo yokuphakamisa iimpahla ukuba idlule emilenzeni incinci. Imilenze emise okwe-C yenziwe ngendlela ethambekileyo okanye egobileyo ukwenza indawo enkulu esecaleni ukwenzela ukuba iimpahla zidlule emilenzeni kakuhle.
2. Ulwahlulo olubanzi lweekhreyini zegirder gantry ezimbini. Iikhreyini eziphindwe kabini zegirder gantry cranes zinamandla okuthwala, ispan enkulu, uzinzo lulonke, kunye neendidi ezininzi, kodwa ubunzima bazo bukhulu kunobo be-single main girder gantry cranes ezinomthamo ofanayo wokuphakamisa. , iindleko nazo ziphezulu. Ngokwamacandelo ahlukeneyo ebhodi engundoqo, inokwahlulwa ibe ziifom ezimbini: ibhokisi yebhokisi kunye ne-truss. Okwangoku, izakhiwo ezibunjwe ngebhokisi zisetyenziswa ngokubanzi.
Ulwahlulo ngokwesakhiwo esingundoqo se-gantry crane:
1. Umbhobho we-truss yifom yesakhiwo esidityaniswe ngentsimbi ye-angle okanye i-I-beam. Ineenzuzo zexabiso eliphantsi, ubunzima obulula kunye nokumelana nomoya olungileyo. Nangona kunjalo, ngenxa yenani elikhulu lamanqaku e-welding kunye neziphene ze-truss ngokwayo, i-truss beam nayo ineziphene ezifana nokuphambuka okukhulu, ukuqina okuphantsi, ukuthembeka okuphantsi, kunye nesidingo sokufunyanwa rhoqo kwamanqaku e-welding. Ifanelekile kwiindawo ezineemfuno ezisezantsi zokhuseleko kunye nomthamo omncinci wokuphakamisa.
2. Ibhokisi yebhokisi idityaniswe kwisakhiwo sebhokisi usebenzisa iiplate zetsimbi, ezineempawu zokhuseleko oluphezulu kunye nokuqina okuphezulu. Ngokuqhelekileyo isetyenziselwa iitoni ezinkulu kunye ne-ultra-large-tonnage gantry cranes. Imiqadi yebhokisi nayo ineempawu zexabiso eliphezulu, ubunzima obunzima, kunye nokunganyangeki kakuhle komoya.
