I-single girder gantry crane luhlobo lwecrane olubandakanya ibhulorho enye exhasa imilenze emibini ye-A-frame ngapha nangapha. Ngokuqhelekileyo isetyenziselwa ukuphakamisa kunye nokuhambisa imithwalo enzima kwiindawo ezingaphandle, ezifana neeyadi zokuthumela, iindawo zokwakha, iindawo zokugcina iimpahla, kunye nezixhobo zokuvelisa.
Nazi ezinye iimpawu eziphambili kunye neempawu zeigirder enye gantry cranes:
I-Bridge Girder: I-Bridge girder yintsimbi ethe tye evula isithuba phakathi kwemilenze emibini ye-gantry crane. Ixhasa indlela yokuphakamisa kwaye ithwala umthwalo ngexesha lokusebenza. I-Single girder gantry cranes ine-bridge girder enye, eyenza ibe lula kwaye ingabizi kakhulu xa kuthelekiswa ne-double girder gantry cranes.
Imilenze kunye neeNkxaso: Imilenze ye-A-frame inika uzinzo kunye nenkxaso kwisakhiwo se-crane. Le milenze ngokuqhelekileyo yenziwe ngentsimbi kwaye idityaniswe phantsi ngokunyathela okanye amavili okuhamba. Ubude kunye nobubanzi bemilenze bunokwahluka ngokuxhomekeke kwiimfuno ezithile zesicelo.
Indlela yokuPhakamisa: Iikhreyini ze-gantry zegirder enye zixhotyiswe ngendlela yokunyusa, njengesixhobo sokunyusela sombane okanye itroli, ehamba ngobude besixhobo sokusigcina. Indlela yokuphakamisa isetyenziselwa ukunyusa, ukuthoba, kunye nokuthutha imithwalo ngokuthe nkqo. Ukuphakama kwamandla e-crane kuxhomekeke kwiinkcukacha ze-hoist okanye i-trolley esetyenzisiweyo.
I-Span kunye noBubude: Ispan ye-single girder gantry crane ibhekiselele kumgama phakathi kwamaziko emilenze yomibini. Ukuphakama kwe-crane kunqunywe ubude obufunekayo bokuphakamisa kunye nokukhutshwa okufunekayo kumthwalo. Le milinganiselo ingenziwa ngokwezifiso ngokusekelwe kwisicelo esithile kunye nemithintelo yendawo.
Ukuhamba: I-cranes ye-gantry ye-girder enye inokuqulunqwa kunye noqwalaselo olusisigxina okanye oluphathwayo. I-gantry cranes elungisiweyo ifakwe ngokusisigxina kwindawo ethile, ngelixa i-gantry cranes ehambayo ixhotyiswe ngamavili okanye iingoma, ezivumela ukuba zihanjiswe ngaphakathi kwendawo echaziweyo.
Inkqubo yokulawula: I-cranes ye-gantry ye-Single girder iqhutywa yinkqubo yokulawula equka i-push-button control pendant okanye i-remote control. Ezi nkqubo zenza ukuba abaqhubi bakwazi ukulawula ukuhamba kwecrane, kuquka ukuphakamisa, ukuthoba, kunye nokunqumla umthwalo.
I-cranes ye-gantry ye-Single girder iyaziwa ngokuguquguquka kwayo, ukulula ukufakela, kunye nokusebenza kakuhle kweendleko. Zifanelekile kwizicelo ezahlukeneyo apho imithwalo ephakathi ukuya enzima kufuneka iphakanyiswe kwaye ihanjiswe ngokuthe tye. Nangona kunjalo, kubalulekile ukuqwalasela izinto ezifana nomthamo womthwalo, umjikelo womsebenzi, kunye neemeko zokusingqongileyo xa ukhetha kwaye usebenza i-crane eyodwa ye-girder gantry ukuqinisekisa ukusebenza okukhuselekileyo nokusebenzayo.
Ukongeza, iinkqubo zolawulo ezisetyenziswa kwi-single girder gantry cranes zidlala indima ebalulekileyo ekuqinisekiseni ukusebenza ngokukhuselekileyo nangokufanelekileyo kwe-crane. Nantsi eminye imiba ephambili yezi nkqubo zolawulo:
- Ulawulo lwe-Pendant: Ulawulo lwe-Pendant lukhetho oluqhelekileyo lolawulo lwe-gantry cranes enye. Ziquka isikhululo esilengayo esiphathwa ngesandla esiqhagamshelwe kwi-crane ngentambo. Isikhululo sependant sibandakanya amaqhosha okanye iiswitshi ezivumela umsebenzisi ukuba alawule iintshukumo ezahlukeneyo zecrane, ezinje ngokuphakamisa, ukwehlisa, ukunqumla ngetroli, kunye nokuhamba ngebhulorho. Ulawulo lwe-pendant lubonelela ngojongano olulula nolucacileyo kumsebenzisi ukulawula iintshukumo zecrane.
- Izilawuli ezikude zikanomathotholo: Izilawuli kude zikanomathotholo ziya zithandwa kakhulu kwiinkqubo zanamhlanje zolawulo lwecrane. Banikezela ngenzuzo yokuvumela umqhubi ukuba alawule ukunyakaza kwe-crane ukusuka kumgama okhuselekileyo, ukubonelela ukubonakala okungcono kunye nokuguquguquka. Izilawuli ezikude zikanomathotholo ziquka isidlulisi esiphathwa ngesandla esithumela iisignali ngaphandle kwamacingo kwiyunithi yomamkeli wecrane. I-transmitter ixhotyiswe ngamaqhosha okanye i-joystick ephindaphinda imisebenzi ekhoyo kulawulo lwependant.
- Ulawulo lwekhabhinethi: Kwizicelo ezithile, iicranes zegirder gantry enye zinokuxhotyiswa ngekhabhini yomsebenzisi. Ikhabhinethi ibonelela ngendawo yokusebenza evaliweyo kumqhubi we-crane, ekhusela kwizinto zangaphandle kunye nokubonelela ngokubonakala okungcono. Inkqubo yokulawula kwikhabhinethi ibandakanya ipaneli yokulawula enamaqhosha, iiswitshi, kunye nezinti zokuvuya ukuze kusebenze iintshukumo zecrane.
- Iidrives eziguquguqukayo ze-Frequency Drives (VFD): Iidrives eziguquguqukayo eziguquguqukayo zihlala zisetyenziswa kwiinkqubo zokulawula ze-gantry cranes enye. Ii-VFDs zivumela ulawulo olugudileyo noluchanekileyo lwezantya zemoto yecrane, nto leyo eyenza ukuba isantya esithe chu kunye nokwehla. Eli nqaku liphakamisa ukhuseleko kunye nokusebenza kakuhle kweentshukumo ze-crane, ukunciphisa ukuguga kunye nokukrazula kumacandelo kunye nokuphucula ukulawula umthwalo.
- Iimpawu zoKhuseleko: Iinkqubo zokulawula i-cranes ye-girder ye-gantry enye ibandakanya iimpawu ezahlukeneyo zokhuseleko. Ezi zingabandakanya amaqhosha okumisa okungxamisekileyo, iinkqubo zokukhusela umthwalo ogqithisiweyo, ukutshintshela umda ukuthintela ukugqithiswa, kunye neenkqubo zokunqanda ukungqubuzana ukuphepha ukungqubana nemiqobo okanye ezinye iikrane. Ezi mpawu zokhuseleko zenzelwe ukukhusela zombini umqhubi we-crane kunye nokusingqongileyo.
- I-Automation kunye nokuCwangciswa kweNkqubo: Iinkqubo zolawulo ezikwinqanaba eliphezulu ze-single girder gantry cranes zinokubonelela ngezakhono zokuzenzekelayo kunye nokucwangcisa. Oku kuvumela ukudala ulandelelwano lokuphakanyiswa kwangaphambili, ukubeka umthwalo ochanekileyo, kunye nokudibanisa nezinye iinkqubo okanye iinkqubo.
Kubalulekile ukuqaphela ukuba inkqubo yolawulo ethile esetyenziswa kwigida enyegantry craneinokwahluka ngokuxhomekeke kumvelisi, imodeli, kunye neenketho zokwenza ngokwezifiso. Inkqubo yokulawula kufuneka ikhethwe ngokusekelwe kwiimfuno zokusebenza, ukuqwalaselwa kokhuseleko, kunye nezinto ezikhethwa ngumqhubi we-crane.
