Ngaphandle Umphezulu weCrane yeGantry Crane yeBlock yeMarble

I-gantry crane luhlobo lonyuso lwasemoyeni olunebhoom exhaswe kwimilenze ye-stowaway, ehamba kunye namavili, iingoma, okanye iinkqubo zikaloliwe ezithwele i-boom, izilingi, kunye ne-hoist.Ikhreyini engaphezulu, edla ngokubizwa ngokuba yibhulorho yebhulorho, imile okwebhulorho ehambayo, ngelixa i-gantry crane inebhulorho engaphezulu exhaswe ngesakhelo sayo.Iibhilidi, imiqadi, kunye nemilenze yinxalenye ebalulekileyo ye-gantry crane kwaye iyahlula kwi-crane ephezulu okanye i-bridge crane.Ukuba ibhulorho ixhaswe ngokungqongqo ngemilenze emibini okanye ngaphezulu ehamba ngeendlela ezimbini ezizinzileyo kumgangatho ophantsi, ngoko ke i-crane ibizwa ngokuba yi-gantry (USA, ASME B30 series) okanye i-goliath (UK, BS 466).

I-gantry crane luhlobo lwekhreyini yasemoyeni enokwakheka kwegirder enye okanye i-double girder exhaswayo emilenzeni eshukunyiswa ngamavili okanye kumzila okanye umzila kaloliwe.Iijekhi zegantry zegirder enye zisebenzisa iijekhi zokunyusa ezahlukeneyo ngokuxhomekeke kuhlobo lomsebenzi, kwaye zingasebenzisa iijacks zesimbo saseYurophu.Ikhono lokuphakamisa i-double-girder gantry crane ingaba ngamakhulu eetoni, kwaye uhlobo lunokuba luyilo lwe-half-girder okanye i-double-leg kunye nomlenze omnye ngendlela ye-skeleton.I-crane encinci, ephathekayo ye-gantry inokwenza iindidi ezifanayo zemisebenzi eyenziwa yi-jib crane, kodwa inokujikeleza indawo yakho xa inkampani yakho ikhula kwaye uqala ukulungisa kunye nokucwangcisa iindawo zokugcina iimpahla.

Iisistim eziphathwayo zegantry nazo zinokubonelela ngokuguquguquka okukhulu kunejib okanye icrane yesitali.Iindidi ezahlukeneyo zeekhreyini eziphezulu zibandakanya i-gantry, i-jib, ibhulorho, indawo yokusebenza, i-monorail, i-overhead, kunye ne-sub-assembly.Ii-cranes ezingaphezulu, ezibandakanya i-gantry cranes, ziyimfuneko kwimveliso emininzi, ukugcinwa, kunye neendawo zokusebenza zemizi-mveliso apho kufuneka ukusebenza ngokufanelekileyo ukuphakamisa nokuhambisa imithwalo enzima.Iikhreyini zedekhi ezingaphezulu zisetyenziselwa ukuphakamisa nokuhambisa izinto ukusuka kwindawo ukuya kwenye ngokukhuselekileyo nangokufanelekileyo.

Iikhreyini zebhulorho eziphindwe kabini zenziwe ngemiqadi emibini yebhulorho encanyathiselwe emzileni, kwaye idla ngokubonelelwa ngezinyusi zentambo yombane engaphezulu kwentambo, kodwa zinokubonelelwa ngezinyusi zamatsheyini ombane angaphezulu ngokuxhomekeke kwisicelo.Ifumaneka kwi-single-leg okanye i-double-leg designs eqhelekileyo, i-Spanco PF-series ye-gantry crane systems inokuxhotyiswa nge-powered traverse.Ezi mfuno zilandelayo zisebenza kuzo zonke iikhreyini zemizi-mveliso ezisetyenziswa kwisiza, kubandakanywa i-automated, i-cockpit-operated, i-gantry, i-semi-gantry, udonga, i-jib, ibhulorho, njl.
