Ikhreyini yebhulorho ejingayo, ekwaziwa njengekhreyini yebhulorho ebaleka ngaphantsi okanye ibhulorho ephantsi, luhlobo lwekhreyini engaphezulu esebenza kwindlela yeenqwelo-moya ephakamileyo. Ngokungafaniyo neekhreyini zesiqhelo eziphezu kwentloko ezinebhanti yebhulorho ebaleka phezu kwemiqadi yendlela yeenqwelo-moya, ikhreyini yebhulorho ejingayo inebhanti yebhulorho ebaleka ngaphantsi kwemiqadi yendlela yeenqwelo-moya. Nazi ezinye iinkcukacha kunye neempawu zeekhreyini zebhulorho ehung:
Ulungelelwaniso: Iikhreyini zebhulorho ephantsi kwehung ngokuqhelekileyo ziquka ibhilida yebhulorho, iilori eziphelayo, indibano yokunyusela/yetroli, kunye nenkqubo yendlela yeenqwelo-moya. Ibhanti yebhulorho, ephethe i-hoist kunye netroli, ifakwe kwiiflange ezisezantsi zemiqadi yendlela yeenqwelo-moya.
Isixokelelwano seNdlela yeenqwelo-moya: Inkqubo yeenqwelo-moya ixhonywe kwisakhiwo sesakhiwo kwaye ibonelela ngendlela yokuba i-crane ihambe ngokuthe tye. Iqulathe imiqadi yendlela yeenqwelo-moya ehambelanayo exhasa isixhasi sebhulorho. Imiqadi yomgaqo weenqwelo-moya ixhonywe ngokuqhelekileyo kwisakhiwo kusetyenziswa ii-hangers okanye izibiyeli.
IBridge Girder: Ibhanti yebhulorho ngumqadi othe tye ovula umsantsa phakathi kwemiqadi yendlela yeenqwelo-moya. Ihamba ecaleni kwendlela yeenqwelo-moya isebenzisa amavili okanye iirola ezifakwe kwiilori zokuphela. Ibhanti yebhulorho ixhasa i-hoist kunye ne-trolley assembly, ehamba kunye nobude be-bridge girder.
INdibano ye-Hoist kunye neTrolley: Indibano ye-hoist kunye ne-trolley inoxanduva lokuphakamisa nokuhambisa imithwalo. Iqukethe i-hoist yombane okanye ye-manual efakwe kwitroli. Itroli ibaleka ecaleni kwebhanti yebhulorho, ivumela i-hoist ukuba imise kwaye ithuthe imithwalo kwindawo yokusebenza.
Ukuguquguquka: Iikhreyini zeebhulorho eziphantsi kwe-Underhung zibonelela ngokuguquguquka ngokwemigaqo yofakelo kunye nokusetyenziswa. Zihlala zisetyenziswa kwizibonelelo apho i-headroom ilinganiselwe okanye apho izakhiwo ezikhoyo zingenakuxhasa ubunzima be-crane ephezulu yendabuko. Iikhreyini eziphantsi kwe-underhung zingafakwa kwizakhiwo ezitsha okanye zifakwe ngokutsha kwizakhiwo ezikhoyo.
Izixhobo zokuVelisa: Iikhreyini eziphantsi kwe-Underhung zihlala zisetyenziswa kwindawo yokuvelisa ukuhambisa imathiriyeli ekrwada, amacandelo, kunye neemveliso ezigqityiweyo ecaleni kwemigca yendibano. Bavumela ukubeka indawo esebenzayo kunye ngokuchanekileyo koomatshini abanzima, izixhobo kunye nezixhobo ngexesha leenkqubo zokuvelisa.
Iindawo zokugcina iimpahla kunye naMaziko okusasaza: Iikhreyini eziphantsi kwe-underhung ziqeshwe kwiindawo zokugcina iimpahla kunye namaziko okusasaza ukusingatha kunye nokuthutha iimpahla, iipalethi kunye nezikhongozeli. Baququzelela ukuhamba kweemveliso ngaphakathi kweendawo zokugcina, ukulayisha kunye nokukhulula iilori, kunye nokulungelelanisa uluhlu.
Ishishini leeMoto: Iikhreyini eziphantsi kwe-Underhung zidlala indima ebalulekileyo kushishino lweemoto. Zisetyenziselwa imisebenzi efana nokuphakamisa kunye nokubeka imizimba yemoto ngexesha lokuhlanganisa, ukuhambisa iindawo ezinzima zemoto ecaleni kwemigca yemveliso, kunye nokulayisha / ukothula izinto ezivela kwiilori.
Umzi-mveliso we-aerospace: Kwishishini le-aerospace, iikhreyini ezijingayo zisetyenziselwa ukuphatha kunye nokudibanisa izinto ezinkulu zenqwelomoya, ezifana namaphiko kunye neefuselage. Bancedisa ekumiseni ngokuchanekileyo kunye nokuhamba kwezi ndawo zinzima kwaye zibuthathaka, ziqinisekisa iinkqubo ezisebenzayo zemveliso.
I-Metal Fabrication: Iikhreyini eziphantsi kwe-Underhung zifumaneka ngokuqhelekileyo kwiindawo zokwenza isinyithi. Zisetyenziselwa ukuphatha nokuthutha amashiti esinyithi esinzima, imiqadi, kunye nezinye izinto zokwakha. Iikhreyini eziphantsi kwe-Underhung zibonelela ngesakhono sokuphakamisa esiyimfuneko kunye nokunyanzeliswa kwemisebenzi eyahlukeneyo yolwakhiwo, kubandakanya ukuwelda, ukusika, kunye nokwenza imisebenzi.
Iicranes eziphantsi kwe-underhung overhead zifumana isicelo kuluhlu olubanzi lwamashishini kunye neendawo apho ukugcinwa kwezinto eziphathekayo kunye nokusebenza ngokuphakamisa okufunekayo.Ubuninzi babo, umthamo womthwalo, kunye nokuguquguquka kubenza babe yimpahla ebalulekileyo kumashishini amaninzi apho ukulawulwa kwezinto ezifanelekileyo kunye nokusebenza kokuphakamisa kubaluleke kakhulu.
