Ngokubanzi, iikhreyini zebhulorho azifane zisetyenziswe ngaphandle xa kuthelekiswa neekhreyini zegantry. Ngenxa yokuba idizayini yayo yesakhiwo ayinayo i-outrigger design, inkxaso yayo ikakhulu ixhomekeke kwizibiyeli kudonga lwefektri kunye neentsimbi ezibekwe kwiipali ezithwala imithwalo. Imo yokusebenza ye-crane yebhulorho ingaba ngumsebenzi ongekho umthwalo kunye nokusebenza komhlaba. Ukusebenza ngokungasebenziyo kukusebenza kweteksi. Ngokuqhelekileyo, ukusebenza komhlaba kukhethiwe kwaye ulawulo olukude lusetyenziswa. Utyando lulula kwaye lukhuselekile. I-gantry crane ayinakufakwa kuphela kwiiworkshops zangaphakathi kodwa ingasetyenziswa ngokuguquguqukayo kwiindawo zangaphandle.
2. Umahluko phakathi kwecrane yebhulorho kunye negantry crane
Okwangoku, kukho iintlobo ezininzi zeekhreyini zebhulorho kunye ne-gantry cranes kwimarike. Abathengi bakhetha iikrane zebhulorho okanye i-gantry cranes ngokweemfuno zabo, ngokukodwa ngokwesakhiwo sezixhobo, indlela yokusebenza, ixabiso, njl.
1. Isakhiwo kunye nemodi yokusebenza
I-crane yebhulorho yenziwe ngentsimbi engundoqo, i-motor, i-winch, inqwelo yokuhamba, ukuhamba ngetroli, njl. Ubungakanani buxhomekeke kwitoni yangempela. Iikhreyini zebhulorho zikwanazo negirder ephindwe kabini kunye nebhanti enye. Iikhreyini ezineetoni ezinkulu ngokuqhelekileyo zisebenzisa imiqadi ephindwe kabini.
I-crane ye-gantry yenziwe nge-beam engundoqo, i-outriggers, i-winch, inqwelo yokuhamba, i-trolley ehambayo, i-cable drum, njl.
2. Imo yokusebenza
Indlela yokusebenza ye-crane yebhulorho inqunyelwe kwimisebenzi yangaphakathi. Ikhonkco linokusebenzisa i-hoists yombane ephindwe kabini, efanelekileyo ukunyuswa kwizityalo zokulungisa, iifektri zemoto, isinyithi kunye nezityalo zoshishino jikelele.
Iikhreyini ze-Gantry zisebenza ngeendlela ezahlukeneyo, ngokuqhelekileyo zineetoni ezincinci ngaphakathi, i-gantry cranes yokwakha inqanawa kunye ne-container gantry cranes ngaphandle, izixhobo zokuphakamisa iitonnage ezinkulu, kunye ne-container gantry cranes zisetyenziselwa ukuphakamisa i-port. Le crane ye-gantry ithatha i-double cantilever structure.
3. Iinzuzo zokusebenza
Iikhreyini zebhulorho ezinamaqondo aphezulu okusebenza ngokubanzi zisebenzisa iikhreyini zesinyithi, ezinamaqondo aphezulu okusebenza, ukusebenza kakuhle, ukusetyenziswa kwamandla aphantsi, kunye nokuthobela imigangatho yokusingqongileyo.
Umgangatho wokusebenza we-gantry cranes ngokubanzi ngu-A3, eyenzelwe i-gantry cranes ngokubanzi. Kwii-cranes ze-gantry ezinkulu ze-tonnage, izinga lokusebenza linokunyuswa kwi-A5 okanye i-A6 ukuba abathengi banemfuno ezizodwa. Usetyenziso lwamandla luphezulu kwaye luyahlangabezana nemigangatho yokhuseleko lokusingqongileyo.
4. Ixabiso lezixhobo
I-crane ilula kwaye inengqiqo, kunye neendleko zokusebenza eziphantsi. Xa kuthelekiswa ne-gantry crane, ixabiso liphantsi kancinci. Nangona kunjalo, ezi zimbini zisafuneka zithengwe ngokwemfuno, kwaye ezi fomu zimbini azifani. Nangona kunjalo, umahluko wexabiso phakathi kwezi zimbini kwiimarike usemkhulu kwaye unempembelelo enkulu. , ukhetho lomenzi, njl., ngoko ke amaxabiso ahluke.
