Njengomunye wemishini yokuphakamisa eyinhloko ezimbonini zezimboni nezokwakha, i-bridge crane idlala indima engenakushintshwa. Eqinisweni, isimiso sokusebenza se-crane yebhuloho futhi silula kakhulu. Ivamise ukuqukatha futhi isebenza ngemishini emithathu kuphela elula: ama-lever, ama-pulleys nama-hydraulic cylinders. Okulandelayo, lesi sihloko sizokwethula umgomo wokusebenza kanye namagama okusebenza ka-crane ongaphezulu ngokuningiliziwe.
Amagama e-BI-ridge Cranes
Umthwalo we-axial – amandla aphelele aqondile esakhiweni sokusekela se-jib crane
Ingxenye yebhokisi - ingxenye ephambanayo engunxande lapho kuhlangana khona imishayo, amaloli, noma ezinye izinto
Ibhuleki elilandelanayo - uhlelo lokukhiya olungadingi amandla ukuze lunikeze ukubhuleka
Ubufakazi bokuqhuma - okwenziwe ngezinto ezingaqhumisi
I-Boom Lower Height (HUB) - Ibanga ukusuka phansi ukuya ohlangothini olungezansi lwe-boom
Amandla okuphakamisa - umthwalo omkhulu wokuphakamisa we-crane
Ijubane lokuphakamisa - isivinini lapho umshini wokuphakamisa uphakamisa umthwalo
Isivinini sokusebenza - isivinini se-crane mechanism kanye ne-trolley
I-Span – ibanga phakathi komugqa omaphakathi wamasondo kuzo zombili iziphetho ze-beam enkulu
Ukuvinjwa okubili - lapho umthwalo olenga ku-hook unamathele ku-crane
Ipuleti lewebhu - ipuleti elixhuma ama-flange aphezulu naphansi we-beam nepuleti lewebhu.
Umthwalo Wesondo - Isisindo isondo elilodwa le-crane elizosithwala (ngamakhilogremu)
Umthwalo wokusebenza - unqunywa izinga lomthwalo, okungaba lula, okuphakathi, okusindayo, noma okungaphezu kwamandla
Idivayisi yokushayela yeBridge Crane
Idivayisi yokushayela iyisisetshenziswa samandla esishayela indlela yokusebenza. Imishini evamile yokushayela ihlanganisa ukushayela kukagesi, ukushayela kwenjini evuthayo yangaphakathi, ukushayela okwenziwa ngesandla, njll. Amandla kagesi awumthombo wamandla ahlanzekile futhi awongayo, futhi ukushayela kukagesi kuyindlela yokushayela eyinhloko yama-cranes anamuhla.
I-Working Mechanism yeBridge Crane
Indlela yokusebenza ye-crane engaphezulu ihlanganisa indlela yokuphakamisa kanye nendlela yokugijima.
1. Umshini wokuphakamisa umshini wokufeza ukuphakamisa izinto uqonde mpo, ngakho-ke uyindlela ebaluleke kakhulu futhi eyisisekelo yama-cranes.
2. Indlela yokusebenza iwumshini ohambisa izinto ngokuvundlile ngokhreni noma ngetroli ephakamisayo, engahlukaniswa umsebenzi wesitimela nomsebenzi ongenamkhondo.
I-Overhead CraneIdivayisi yokulanda
I-pickup idivayisi iyisisetshenziswa esixhumanisa izinto ku-crane ngokusebenzisa ihuku. Sebenzisa izinhlobo ezihlukene zamadivayisi wokulandwa ngokusekelwe kuhlobo, ifomu, nosayizi wento emisiwe. Imishini efanele inganciphisa umsebenzi wabasebenzi futhi ithuthukise kakhulu ukusebenza kahle. Izidingo eziyisisekelo zokuvimbela iwintshi ukuthi ingawi nokuqinisekisa ukuphepha kwabasebenzi kanye nemishini ngaphandle kokulimala kwewintshi.
I-Overhead Travelling Crane Control System
Ilawulwa kakhulu uhlelo lukagesi ukuze kusetshenziswe wonke ukunyakaza kwe-crane mechanism yemisebenzi ehlukahlukene.
Ama-cranes amaningi amabhuloho aqala ukusebenza aqonde phezulu noma avundlile ngemva kokucosha umshini wokuphakamisa, akhiphe lapho aya khona, athulule uhambo oluya endaweni yokwamukela, aqedele umjikelezo wokusebenza, bese eqhubeka nokuphakamisa okwesibili. Ngokuvamile, umshini wokuphakamisa wenza umsebenzi wokukhipha, ukuphatha, kanye nokuthulula ngokulandelana, ngezindlela ezihambisanayo ezisebenza ngezikhathi ezithile. Imishini yokuphakamisa isetshenziswa kakhulu ukuphatha izinto zempahla eyodwa. Ifakwe amabhakede okubamba, ingakwazi ukuphatha izinto ezixegayo njengamalahle, insimbi, nokusanhlamvu. Ifakwe amabhakede, ingaphakamisa izinto eziwuketshezi njengensimbi. Eminye imishini yokuphakamisa, njengamakheshi, ingasetshenziswa futhi ukuthwala abantu. Kwezinye izimo, izinto zokuphakamisa ziphinde zibe umshini oyinhloko osebenzayo, njengokulayisha nokuthulula izinto emachwebeni naseziteshini.
