I-crane ye-semi-gantry ithatha i-cantilever yokuphakamisa isakhiwo, kunye necala elinye elixhaswe phantsi kunye nelinye icala limisiwe kwi-girder. Olu yilo lwenza ukuba i-semi-gantry crane ibe bhetyebhetye kwaye ikwazi ukulungelelanisa kwiindawo ezahlukeneyo zemisebenzi kunye neemeko.
Iikhreyini ze-semi-gantry ziyakwazi ukwenzeka kakhulu kwaye zinokuyilwa kwaye zenziwe ukuba zihambelane neemfuno ezithile. Ingenziwa ngokwezifiso ngokusekelwe kumthwalo wokusebenza, ubude kunye neemfuno zokuphakama ukuhlangabezana neemfuno zezicelo ezahlukeneyo.
Iicranes ze-semi-gantry zineenyawo ezincinci kwaye zifanelekile ukusebenza kwiindawo ezilinganiselwe. Icala elinye le-bracket yalo lixhaswa ngokuthe ngqo emhlabeni ngaphandle kwezakhiwo zenkxaso ezongezelelweyo, ngoko kuthatha indawo encinci.
Iikhreyini ze-semi-gantry zineendleko eziphantsi zokwakha kunye namaxesha okumiswa ngokukhawuleza. Xa kuthelekiswa ne-gantry cranes epheleleyo, i-semi-gantry cranes inesakhiwo esilula kwaye kulula ukuyifaka, ngoko inokunciphisa kakhulu iindleko zokwakha kunye nexesha lokufaka.
Amazibuko kunye neZibuko: Iikhreyini ze-Semi gantry zixhaphake ukufunyanwa kumazibuko kunye namachweba kwimisebenzi yokuphatha imithwalo. Zisetyenziselwa ukulayisha kunye nokukhulula izitya zokuthutha kwiinqanawa kwaye zithuthwe ngaphakathi kwendawo yezibuko. Iikhreyini ze-Semi gantry zibonelela ngokuguquguquka kunye nokuguquguquka ekuphatheni izikhongozeli zobukhulu obahlukeneyo kunye nobunzima.
Ishishini elinzima: Imizi-mveliso efana nentsimbi, imigodi, kunye namandla idla ngokufuna ukusetyenziswa kweekhreyini ze-semi gantry ukuphakamisa nokuhambisa izixhobo ezinzima, oomatshini kunye nemathiriyeli ekrwada. Zibalulekile kwimisebenzi efana nokulayisha / ukukhulula iilori, ukufudusa amacandelo amakhulu, kunye nokunceda kwimisebenzi yokulondoloza.
Umzi-mveliso weemoto: Ii-Semi gantry cranes zisetyenziswa kwimizi-mveliso yokuvelisa iimoto ukuphakamisa nokubeka imizimba yemoto, iinjini, kunye nezinye izinto ezinzima zemoto. Bancedisa ekusebenzeni komgca wendibano kwaye baququzelele ukuhamba kakuhle kwezixhobo kumanqanaba ahlukeneyo okuvelisa.
Ulawulo lweNkunkuma: Iikhreyini ezingamagantry ee-semi gantry ziqeshwe kwiindawo zolawulo lwenkunkuma ukuze kuphathwe kwaye kuthuthwe inkunkuma eninzi. Zisetyenziselwa ukulayisha izikhongozeli zenkunkuma kwiilori, ukuhambisa imathiriyeli yenkunkuma ngaphakathi kwendawo, kwaye zincedise kwinkqubo yokurisayikilisha neyokulahlwa.
Uyilo: Inkqubo iqala ngesigaba soyilo, apho iinjineli kunye nabayili baphuhlisa iinkcukacha kunye noyilo lwe-semi gantry crane. Oku kubandakanya ukugqiba umthamo wokuphakamisa, ubude, ubude, inkqubo yokulawula, kunye nezinye izinto ezifunekayo ngokusekelwe kwiimfuno zomthengi kunye nesicelo esijoliswe kuyo.
Ukuyilwa kwaMalungu: Nje ukuba uyilo lugqityiwe, ukwenziwa kwamacandelo ahlukeneyo kuyaqala. Oku kubandakanya ukusika, ukubunjwa, kunye nokuwelda intsimbi okanye iipleyiti zetsimbi ukwenza ezona nxalenye zesakhiwo, ezifana ne-gantry beam, imilenze kunye ne-crossbeam. Amacandelo afana ne-hoist, iitroli, iiphaneli zombane, kunye neenkqubo zokulawula nazo zenziwe ngeli xesha.
Unyango loMphezulu: Emva kokwenziwa, amacandelo angena kwiinkqubo zonyango lomphezulu wokomeleza ukuqina kwawo kunye nokukhuselwa kumhlwa. Oku kunokubandakanya iinkqubo ezifana nokuqhushumba, ukupeyinta, nokupeyinta.
INdibano: Kwinqanaba lendibano, izinto ezenziweyo ziyadityaniswa kwaye zidityaniswe ukuze zenze i-semi gantry crane. I-gantry beam idibene nemilenze, kwaye i-crossbeam ifakwe. Iindlela zokuxhoma kunye netroli zifakiwe, kunye neenkqubo zombane, iipaneli zokulawula, kunye nezixhobo zokhuseleko. Inkqubo yokuhlanganisa ingabandakanya i-welding, i-bolting, kunye nokulungelelanisa amacandelo ukuqinisekisa ukufaneleka kunye nokusebenza ngokufanelekileyo.
