A Double girder Bridge Cranendi imodzi mwamayankho ofunikira kwambiri okweza omwe amagwiritsidwa ntchito pakuwongolera zinthu zamakono. Mosiyana ndi ma crane amtundu umodzi, crane yamtunduwu imatenga zomangira ziwiri zofanana zomwe zimathandizidwa ndi magalimoto omaliza kapena zonyamula mbali zonse. Nthawi zambiri, crane ya double girder bridge imapangidwa kuti ikhale yothamanga kwambiri, yokhala ndi trolley kapena trolley yotseguka yoyenda panjanji yomwe imayikidwa pamwamba pa zotchingira. Mapangidwe awa amawonjezera kutalika kwa mbedza ndikukweza bwino, kupangitsa kuti ikhale chisankho chokondedwa kwa malo omwe amafunikira magwiridwe odalirika pansi pazovuta.
Mapangidwe ndi Magwiridwe Antchito
Mapangidwe amitengo yapawiri amapereka mphamvu zambiri komanso kukhazikika, zomwe zimapangitsa kuti crane igwire ntchito zolemetsa zonyamula komanso nthawi yayitali. Pachifukwa ichi, acrane yogwira ntchito yolemetsanthawi zambiri amamangidwa ngati chitsanzo cha double girder. Kuyika kwa chokwezera pakati kapena pamwamba pa zotchingira kumagwiritsa ntchito bwino malo oyimirira, zomwe zimathandiza oyendetsa ntchito kuti akwaniritse kutalika kokweza. Popeza kuti zigawozi, kuphatikizapo trolley ndi trolley yotseguka, ndizovuta kwambiri komanso zolimba, mtengo wa double girder bridge crane nthawi zambiri ndi wokwera kuposa wa crane imodzi yokha. Komabe, zopindulitsa zanthawi yayitali pakugwirira ntchito komanso kukhazikika zimatsimikizira kusungitsa ndalama pazofunsira zofunidwa.
Mitundu Yama Cranes a Double Girder Overhead
Pali mitundu ingapo yamafakitale apamwamba cranemapangidwe omwe amagwera pansi pa gulu la double girder. Mitundu yotchuka imaphatikizapo ma cranes a QD ndi LH, omwe amagwiritsidwa ntchito kwambiri ponyamula katundu wolemetsa. Ma cranes amtundu waku Europe monga QDX ndi NLH amapezekanso, omwe amapereka mawonekedwe ophatikizika, kulemera kwakufa kopepuka, ndi zida zapamwamba monga kutembenuka pafupipafupi komanso kukweza-liwiro kawiri. Zatsopanozi zimapangitsa kuti makina opangira mafakitale aku Europe akhale osalala, osagwiritsa ntchito mphamvu zambiri, komanso oyeretsedwa bwino, osangalatsa kwa makasitomala omwe amawona ntchito ndi kapangidwe kake.
Top Running vs. Under Running Configurations
TheDouble girder Bridge Craneakhoza kukhazikitsidwa ngati pamwamba kuthamanga kapena pansi kuthamanga dongosolo. Mapangidwe othamanga kwambiri amapereka kutalika kwakukulu kwa mbedza ndi chipinda chapamwamba, kuwapangitsa kukhala abwino kwa malo omwe kukulitsa malo okweza ndikofunikira. Pansi pa kuthamanga pawiri girder cranes, Komano, imayimitsidwa kuchokera mnyumbamo's kapangidwe ka denga ndipo ndizothandiza kumadera omwe ali ndi mutu wocheperako. Komabe, pansi pazitsanzo zothamanga nthawi zambiri zimakhala zovuta komanso zokwera mtengo, choncho m'mapulogalamu ambiri, crane yolemetsa yolemetsa imamangidwa ngati njira yothamanga kwambiri.
Zaukadaulo ndi Ubwino wake
Zinthu zingapo zapamwamba zimawonjezera kudalirika kwa double girder crane system. Mtengo waukulu nthawi zambiri umatenga mawonekedwe a truss, omwe amaphatikiza kulemera kwakukulu ndi mphamvu yolemetsa komanso kukana kwamphamvu kwa mphepo. Mapini ndi maulalo a bawuti amapangidwa motalikirana ndi mita 12, kufewetsa zoyendera ndi kuphatikiza. Komanso, crane akhoza okonzeka ndi Siemens kapena Schneider magetsi mbali monga muyezo, kuonetsetsa kudalirika ntchito mosalekeza. Zosankha monga kutembenuka pafupipafupi, kuwunika kwa chitetezo cha PLC, ngakhale seti ya jenereta ya dizilo ikhoza kuwonjezeredwa kuti musinthe makinawo. Zinthu izi zimapangitsa kuti crane yamakampani ikhale yamphamvu komanso yosinthika kuti igwirizane ndi zochitika zapadera.
Mapulogalamu mu Heavy Industry
Thecrane yogwira ntchito yolemetsandiye chisankho choyamba cha malo ogwirira ntchito, mafakitale azitsulo, malo osungiramo zombo, ndi ntchito zazikulu zomanga kumene katundu wolemera kwambiri ayenera kusunthidwa bwino ndi mosamala. Ndi mitundu ingapo ya ma crane, kutalika kwa mbedza, komanso kuthamanga kwapaulendo, ma crane awiri a girder amatha kukhazikitsidwa kuti agwirizane ndi zosowa zenizeni zamafakitale olemera. Kaya ili ndi trolley ya hoist kapena trolley yotseguka, chiwombankhanga cha Double girder Bridge chimathandiza kwambiri ponyamula ndi kunyamula katundu wambiri.
Crane ya Double girder Bridge ndiye msana wa ntchito zambiri zonyamula mafakitale. Ndi kapangidwe kake kolimba, ukadaulo wapamwamba kwambiri, komanso kukweza kokwezeka kwapamwamba, imayima ngati makina abwino kwambiri opangira mafakitale omwe amafunikira kudalirika, chitetezo, komanso magwiridwe antchito apamwamba. Monga crane yogwira ntchito yolemetsa, imachita bwino kwambiri kuposa mapangidwe a girder imodzi ndipo imapereka phindu kwanthawi yayitali, kupangitsa kuti ikhale yankho labwino kwambiri pakukakamiza kugwiritsa ntchito zinthu.
