Kwishishini lokuvelisa ngokubanzi, imfuno yokugcina ukuhamba kwezinto, ukusuka kwizinto eziluhlaza ukuya ekuqhubeni, kwaye emva koko ukupakisha kunye nokuthutha, kungakhathaliseki ukuba uphazamiseko lwenkqubo, luya kubangela ilahleko kwimveliso, ukukhetha izixhobo zokuphakamisa ezifanelekileyo kuya kuba luncedo ukugcina. inkqubo yemveliso jikelele yenkampani kwimo ezinzile kwaye egudileyo.
I-SEVENCRANE inikezela ngeentlobo ezahlukeneyo ze-crane ezicwangcisiweyo, ukuqhutyelwa ngokubanzi kunye nokuveliswa kwemveliso, njenge-crane yebhulorho, i-monorail crane, i-gantry crane ephathekayo, i-jib crane, i-gantry crane, njl., ukwenzela ukuba kuqinisekiswe ukuzinza kwinkqubo yokucubungula kunye nokhuseleko lokuvelisa, thina ngokuqhelekileyo bamkela itekhnoloji yokuguqula amaza kunye nokuthintela itekhnoloji yokujingi kwikhreyini.
Ubukhulu becala yenziwe ngumqadi ophambili, umqa womhlaba, i-outrigger, umzila wokubaleka, inxalenye yombane, i-hoist kunye nezinye iindawo.
Umzila kaloliwe onyuswe kwi-gantry cranes ibandakanya i-double cantilever single gantry cranes, i-single cantilever single gantry cranes, i-gantry cranes enye ngaphandle kwe-cantilever.
Uphawu lwe-single girder gantry crane
1. I-rail ifakwe kwi-gantry crane inesakhiwo esilula, ukusebenza ngokufanelekileyo, ukuveliswa kunye nokufakwa ngokufanelekileyo. Uninzi lwemiqadi ephambili ziifreyimu ezimile okwebhokisi ngaphandle komkhondo. Xa kuthelekiswa nohlobo lwe-portal ye-double main, ubunzima obupheleleyo bubuthathaka.
2. Ngokwemisebenzi eyahlukeneyo, izixhobo zokukhusela ukulayisha ngaphezulu zingahlulwa zibe ziindidi ezimbini: uhlobo lokuvala oluzenzekelayo kunye nohlobo olubanzi. Ngokohlobo lwesakhiwo, lwahlulwe ngohlobo lombane kunye nohlobo lomatshini.
Ngaphantsi kweemeko eziqhelekileyo, ayinakusebenza kwiindawo ezineendaba ezinokutsha kunye neziqhushumbisi. Kananjalo ayisebenzisi kwimisebenzi enetyhefu kunye nomhlaba kunye nokulawula igumbi. Ukuba kufuneka uyisebenzise kwindawo ekhethekileyo, kufuneka uxelele umenzi ukuba enze izinto ezikhethekileyo xa kuthengwa.
3. I-single girder gantry crane ineempawu zezinga eliphezulu lokusetyenziswa kwendawo, uluhlu olukhulu lokusebenza, ukulungelelaniswa okubanzi kunye nokuguquguquka okunamandla, kwaye isetyenziswa ngokubanzi kwiiyadi ze-port cargo. Xa umqhubi we-crane enqaba ukuphakamisa ngenxa yokuba into inzima kakhulu, umlawuli kufuneka athathe amanyathelo okunciphisa umthwalo wokunyusa, kwaye kunqatshelwe ngokungqongqo ukuqinisa ukusebenza kwe-crane.
4. I-gantry crane exhonywe kumzila kaloliwe kufuneka ibandakanye indlela yokuphakamisa, njl. Indlela yokuxhoma ngokuqhelekileyo yi-CD okanye i-MD yohlobo lokunyuswa kombane.
