Thedouble girder gantry crane, yomwe imatchedwanso double beam gantry crane, ndi imodzi mwa mitundu yomwe imagwiritsidwa ntchito kwambiri pamagetsi olemera kwambiri. Amapangidwa makamaka kuti azigwira ntchito zazikulu komanso zolemetsa, zomwe zimapangitsa kukhala njira yabwino yothetsera ntchito zamafakitale, zomanga, ndi zogwirira ntchito. Mosiyana ndi ma girder amtundu umodzi, mawonekedwe a girder awiri amapereka mphamvu yokweza kwambiri, kukhazikika kwakukulu, komanso nthawi yayitali, yomwe imapangitsa kuti ikhale yoyenera kunyamula zinthu zovuta kwambiri.
Mwadongosolo, adouble girder gantry craneimakhala ndi zigawo zingapo zofunika, kuphatikizapo matabwa akuluakulu, matabwa omalizira, miyendo yothandizira, matabwa apansi, trolley run track, cab ya oyendetsa, hoist trolley, crane travelling mechanism, ndi makina apamwamba a magetsi. Zigawozi zimagwirira ntchito limodzi kuti zitsimikizike kuti zinyamulidwa bwino, zotetezeka, komanso mwaluso. Mapangidwe amphamvu amalola kuti crane igwire ntchito panjanji zapansi, zomwe zimathandizidwa kumapeto kapena kumapeto kwina, zomwe zimapereka kusinthasintha kwa zochitika zosiyanasiyana zogwirira ntchito.
Mapulogalamu
Thedouble girder gantry cranendi njira yonyamulira yolemetsa yokhala ndi mphamvu zolemetsa zolimba, kapangidwe kake kosavuta, komanso ntchito yabwino. Amagwiritsidwa ntchito kwambiri m'mafakitale ndi zochitika zosiyanasiyana, kuphatikizapo:
Makampani Opanga: Pamagalimoto, kupanga zombo, mphamvu zamphepo, ndi kupanga makina, makina opangira ma gantry awiri amagwiritsidwa ntchito kusonkhanitsa, kupasula, ndi kunyamula zida zazikulu. Imathandiziranso kasamalidwe ka zinthu zopangira ndi zinthu zomalizidwa, kuwonetsetsa kuti njira zopangira zikuyenda bwino.
♦ Gawo la Zomangamanga: Pamalo omanga, craneyi imagwiritsidwa ntchito kwambiri pokweza ndi kusuntha zida zomangira zolemera. Kuthekera kwake kuthana ndi zigawo zazikulu zamapangidwe kumathandizira kuyika bwino, kumathandizira ntchito yomanga yotetezeka, ndikufulumizitsa kumaliza ntchito.
♦Kukonza ndi Kusungirako katundu:Heavy duty gantry cranesndizofunikira m'malo osungiramo zinthu komanso malo osungiramo katundu kuti azitsitsa, kutsitsa, ndikusunga ziwiya. Kuthekera kwawo kolimba komanso magwiridwe antchito ambiri kumathandizira kuti katundu ayende mwachangu komanso kasamalidwe kabwino ka malo osungiramo zinthu.
♦ Madoko ndi Malo Okwerera: M'mabwalo a makontena ndi malo onyamula katundu wambiri, makolaniwa ndi ofunikira kwambiri ponyamula zotengera zolemera ndi katundu wambiri. Kuchita kwawo kodalirika kumakwaniritsa zofunikira zogwirira ntchito pamadoko, kukonza bwino pakutsitsa ndi kutsitsa.
♦ Malo Onyamulira Sitima ya Sitima: Muzoyendera za njanji, ma crani onyamula katundu wolemera amagwiritsidwa ntchito pokweza ndi kutsitsa zitsulo, matabwa, makina, ndi katundu wina wochuluka. Amagwiritsidwanso ntchito pomanga njanji pokweza njanji, zigawo za mlatho, ndi zida zina zazikulu zomangira.
♦ Malo Osungira Panja ndi Mayadi Ofunika: Chifukwa cha kukweza kwawo kwakukulu komanso kutalika kwake,girder gantry cranesndizoyenera malo osungiramo zinthu zotseguka, masheya, ndi malo ochitirako ntchito zolemetsa, zomwe zimapereka mayankho ogwira mtima pakunyamula katundu wamkulu.
Ndi magwiridwe ake odalirika, mphamvu zonyamula katundu, komanso moyo wautali wautumiki, crane ya double girder gantry crane imagwiritsidwa ntchito kwambiri m'madoko, malo opangira zombo, mafakitale, malo osungiramo zinthu, ndi malo omanga. Sikuti zimangowonjezera zokolola komanso zimatsimikizira chitetezo ndi mphamvu pakugwira ntchito kwazinthu zolemetsa.
Mitundu Yaikulu ndi Kukonzekera kwa Double Girder Gantry Cranes
Ma crane a Double girder gantry ndi amodzi mwa mitundu yomwe imagwiritsidwa ntchito kwambiri pazida zonyamulira pamwamba. Zokhala ndi zomangira ziwiri zolimba zochirikizidwa ndi miyendo yowongoka, ma craneswa amayenda panjanji kapena mawilo ndipo amapereka mphamvu, kukhazikika, komanso kukweza bwino kwambiri. Ndiabwino kunyamula katundu wolemetsa m'malo ambiri ogwirira ntchito ndipo amagwiritsidwa ntchito kwambiri m'malo osungiramo zombo, m'mafakitole, malo opangira zinthu, ndi malo omanga. Kutengera ndi malo ogwirira ntchito, pali mitundu ingapo yayikulu ndi masinthidwe a ma cranes a double girder gantry.
♦ Full Gantry Crane - Thecrane yonse ya gantryamathamanga pa njanji atagona pansi, ndi miyendo yonse imayenda pa njanji. Mapangidwewa ndi oyenerera makamaka ku ntchito zakunja monga madoko, zombo, mabwalo azitsulo, ndi malo omanga, kumene kukweza kwakukulu ndi kuyenda kwa zipangizo zolemera kumafunika.
♦ Semi-Gantry Crane - Thecrane ya semi-gantryili ndi mbali imodzi yothandizidwa ndi mwendo woyenda pamtunda, pamene mapeto ena amathandizidwa ndi nyumba yomwe ilipo kale kapena mlongoti wokhazikika. Mapangidwewa amathandiza kusunga malo ndipo ndi oyenera ma workshop a m'nyumba kapena malo omwe ali ndi malo ochepa ogwira ntchito. Masinthidwe onse a single girder semi-gantry ndi double girder semi-gantry akupezeka kutengera zofunikira za katundu.
♦ Ma Cranes a Rail Mounted Gantry (RMG) -Njanji zokwera ma gantry cranesamagwiritsidwa ntchito kwambiri m'materminals ndi ma intermodal mayadi. Kugwira ntchito panjanji zapansi panthaka, amanyamula ndi kutsitsa makontena kuchokera m'sitima, m'magalimoto, ndi m'sitima, zomwe zimapatsa kulondola komanso zokolola zambiri pakunyamula zotengera.
♦ Ma Cranes a Rubber Tyred Gantry (RTG) - Okhala ndi matayala olimba a labala m'malo mwa njanji zokhazikika,Zithunzi za RTGkupereka kusinthasintha pazipita ndi kuyenda. Amagwiritsidwa ntchito nthawi zambiri m'mabwalo osungiramo zinthu, malo osungiramo zinthu, ndi malo opangira zinthu, pomwe kuthekera koyenda paokha m'malo osiyanasiyana ndikofunikira.
N'chifukwa Chiyani Mumatikhulupirira?
Ndi zaka zambiri pakupanga crane ndi kupanga, timapereka odalirika, ochita bwino kwambirigirder gantry craneszokonzedwa kuti zikwaniritse zosowa zamakampani osiyanasiyana. Zida zathu zimamangidwa ndiukadaulo wapamwamba, kuwongolera kokhazikika, ndi zida zolimba, kuwonetsetsa moyo wautali wautumiki komanso magwiridwe antchito otetezeka. Makasitomala athu ambiri akupitilizabe kugwiritsa ntchito makina athu kwazaka zambiri, kutsimikizira kuti amakhulupirira komanso kukhutira. Kutisankha kumatanthauza kusankha bwenzi lodalirika lomwe lingathe kupereka mayankho okweza bwino komanso chithandizo chabwino kwambiri pambuyo pogulitsa.
