Panja Panja Pamwamba Crane Gantry Crane Ya Marble Block

Gantry crane ndi mtundu wa zokwezera mlengalenga zomwe zimakhala ndi mayendedwe okwera pamawilo, njanji, kapena masitima apamtunda omwe amanyamula ma boom, gulaye, ndi kukwera. Crane ya pamwamba, yomwe nthawi zambiri imatchedwa bridge crane, imapangidwa ngati mlatho woyenda, pamene gantry crane ili ndi mlatho wopita pamwamba wothandizidwa ndi chimango chake. Zomangamanga, mizati, ndi miyendo ndi mbali zofunika kwambiri za crane ya gantry ndipo imasiyanitsa ndi crane yam'mwamba kapena mlatho. Ngati mlatho umayendetsedwa mwamphamvu ndi miyendo iwiri kapena kuposerapo yoyenda motsatira njira ziwiri zokhazikika pansi, ndiye kuti crane imatchedwa gantry (USA, ASME B30 series) kapena goliath (UK, BS 466).

Gantry crane ndi mtundu wa crane ya mlengalenga yomwe imakhala ndi mawonekedwe a girder imodzi kapena ma girder awiri omwe amathandizidwa ndi miyendo yomwe imayendetsedwa ndi mawilo kapena njanji kapena masitima apamtunda. Ma Crane a Single-girder gantry amagwiritsa ntchito ma jacks osiyanasiyana kutengera mtundu wa ntchito, komanso amatha kugwiritsa ntchito ma jacks amtundu waku Europe. Kuthekera kokweza kwa crane ya double-girder gantry crane kumatha kukhala matani mazana, ndipo mtunduwo ukhoza kukhala kapangidwe ka theka-girder kapena miyendo iwiri yokhala ndi mwendo umodzi ngati mafupa. Gantry crane yaying'ono, yonyamula imatha kugwira ntchito zofanana ndi zomwe jib crane imachita, koma imatha kuyendayenda pamalo anu pomwe kampani yanu ikukula ndikuyamba kukhathamiritsa ndikukonza malo osungira.

Makina onyamula a gantry amathanso kukhala osinthika kwambiri kuposa jib kapena crane. Mitundu yosiyanasiyana yama cranes apamtunda imaphatikizapo gantry, jib, bridge, workstation, monorail, overhead, ndi sub-assembly. Ma cranes apamtunda, kuphatikiza ma crane a gantry, ndi ofunikira pakupanga, kukonza, ndi malo ogwirira ntchito m'mafakitale komwe kumafunika kuchita bwino kuti anyamule ndi kusuntha katundu wolemetsa. Ma cranes okwera pamwamba amagwiritsidwa ntchito kukweza ndi kusuntha zinthu kuchokera kumalo amodzi kupita kwina motetezeka komanso moyenera momwe mungathere.

Ma cranes a Double girder Bridge amapangidwa ndi matabwa awiri a mlatho omwe amamangiriridwa panjanji, ndipo nthawi zambiri amapatsidwa ma elevator a chingwe chamagetsi, koma amathanso kupatsidwa ma elevator amagetsi apamwamba kutengera momwe angagwiritsire ntchito. Zopezeka m'miyendo imodzi kapena zowoneka bwino za miyendo iwiri, Spanco PF-mndandanda wamakina a gantry crane amatha kukhala ndi njira yodutsa. Zofunikira zotsatirazi zikugwiranso ntchito pa makina onse opangira mafakitale omwe amagwiritsidwa ntchito pamalopo, kuphatikiza makina opangira ma cockpit, gantry, semi-gantry, wall, jib, bridge, etc.
