A I-double girder bridge craneingenye yezixazululo ezibaluleke kakhulu zokuphakamisa ezisetshenziswa ekuphatheni impahla yesimanje. Ngokungafani nama-cranes ama-single girder, lolu hlobo lwe-crane luthatha amagida amabili ahambisanayo asekelwa amaloli noma izinqola ohlangothini ngalunye. Ezimweni eziningi, i-double girder bridge crane iklanywe ngokusebenza okuphezulu okugijima, ne-hoist trolley noma i-winch trolley evulekile ehamba ngomzila ofakwe ngaphezu kwamagida. Lo mklamo ukhulisa ubude be-hook nokusebenza kahle kokuphakamisa, okwenza kube ukukhetha okuthandwayo kwezindawo ezidinga ukusebenza okuthembekile ngaphansi kwezimo eziyinselele.
Izici Zokuklama Nokusebenza
Idizayini yemishayo emibili ihlinzeka ngamandla amakhulu nokuzinza, okuvumela i-crane ukuthi ibambe amandla okuphakamisa asindayo kanye nezikhala ezinde. Ngenxa yalokhu, i-I-crane esebenza kanzima engaphezuluivame ukwakhiwa njengemodeli yegida eliphindwe kabili. Ukubekwa kwe-hoist phakathi noma ngaphezulu kwamagida kwenza kusetshenziswe kangcono indawo eqondile, okuvumela opharetha ukuba bafinyelele ukuphakama okuphezulu kokuphakamisa. Njengoba izakhi, ezifaka i-hoist trolley kanye ne-winch trolley, ziyinkimbinkimbi kakhulu futhi ziqinile, izindleko ze-double girder bridge crane ngokuvamile ziphakeme kune-single girder crane. Kodwa-ke, izinzuzo zesikhathi eside ekusebenzeni nokuqina zithethelela ukutshalwa kwezimali kwezicelo ezifunayo.
Izinhlobo zama-Double Girder Overhead Cranes
Kunezinhlobo eziningana zei-crane ephezulu yezimboniimiklamo ewela ngaphansi kwesigaba se-double girder. Amamodeli adumile afaka ama-cranes e-QD kanye ne-LH, asetshenziswa kakhulu ekuphakamiseni umsebenzi osindayo ojwayelekile. Okhrayini besitayela sase-Europe njenge-QDX ne-NLH nabo bayatholakala, banikela ngesakhiwo esihlangene kakhudlwana, isisindo esifile esilula, nezici ezithuthukisiwe ezifana nokuguqulwa kwemvamisa kanye nokuphakamisa isivinini esikabili. Lezi zindlela ezintsha zenza i-European industry overhead crane ishelele, isebenzise amandla kakhudlwana, futhi icwengisiswe ngobuhle, ihehe amakhasimende akwazisa kokubili ukusebenza nokuklama.
Ukugijima Okuphezulu vs. Ukucushwa Okungaphansi Kokusebenza
II-double girder bridge craneingalungiswa njengesistimu esebenzayo ephezulu noma engaphansi kwesistimu esebenzayo. Imiklamo yokugijima ephezulu ihlinzeka ngobude obukhulu kakhulu behuku kanye negumbi eliphezulu, okubenza balungele izindawo lapho ukukhulisa isikhala sokuphakamisa kubaluleke kakhulu. Ngaphansi kokugijima ama-double girder cranes, ngakolunye uhlangothi, amisiwe esakhiweni's isakhiwo sophahla futhi ziwusizo ezindaweni ezine-headroom elinganiselwe. Kodwa-ke, ngaphansi kwamamodeli asebenzayo ngokuvamile ayinkimbinkimbi kakhulu futhi ayabiza, ngakho-ke kuzinhlelo zokusebenza eziningi, i-crane ye-heavy duty duty yakhiwe njengesistimu yokusebenza ephezulu.
Izici Zobuchwepheshe Nezinzuzo
Izici eziningi ezithuthukile zithuthukisa ukuthembeka kwesistimu ye-double girder crane. I-beam eyinhloko ivame ukuthatha isakhiwo se-truss, esihlanganisa isisindo esilula esinamandla omthwalo ophezulu kanye nokumelana nomoya onamandla. Izikhonkwane nezixhumanisi zebhawodi zakhiwe ngezikhawu ezingamamitha ayi-12, okwenza kube lula ezokuthutha nokuhlanganisa. Ngaphezu kwalokho, i-crane ingahlonywa izingxenye zikagesi ze-Siemens noma ze-Schneider njengezinga elijwayelekile, ukuqinisekisa ukwethembeka ekusebenzeni okuqhubekayo. Izici ozikhethela zona njengokuguqulwa kwemvamisa, ukugadwa kokuphepha kwe-PLC, ngisho nesethi yejeneretha yedizili ingangezwa ukwenza uhlelo ngendlela oyifisayo. Lezi zici zenza i-crane ye-industrial overhead ingabi namandla kuphela kodwa futhi ivumelane nezimo zokusebenza eziyingqayizivele.
Izicelo Embonini Enzima
II-crane esebenza kanzima engaphezuluukukhetha kokuqala kwezindawo zokusebenzela, izimboni zensimbi, izindawo zemikhumbi, kanye namaphrojekthi amakhulu wokwakha lapho imithwalo esinda kakhulu kufanele ithuthwe kahle futhi ngokuphepha. Ngobubanzi obubanzi be-crane, ubude be-hook, nesivinini sokuhamba, ama-cranes ama-double girder angalungiswa ukuze ahambisane nezidingo ezithile zezimboni ezinzima. Kungakhathaliseki ukuthi ifakwe isistimu ye-hoist trolley noma isistimu ye-winch trolley evulekile, i-double girder bridge crane inikeza ukusebenza okungenakuqhathaniswa ukuphakamisa nokuthutha imithwalo emikhulu.
I-double girder bridge crane iwumgogodla wemisebenzi eminingi yokuphakamisa izimboni. Ngesakhiwo sayo esiqinile, ubuchwepheshe obuthuthukisiwe, namandla okuphakamisa aphakeme, ime njenge-crane ekahle yezimboni yezindawo ezidinga ukwethembeka, ukuphepha nokusebenza kahle okuphezulu. Njengokhrane osebenza phezulu osindayo, udlula imiklamo yegirder eyodwa futhi unikeza inani lesikhathi eside, okwenza kube yisixazululo esingcono kakhulu sokufuna izicelo zokubamba izinto ezibonakalayo.
