II-crane eyodwa yegirder ngaphezuluingukhrane webhuloho ongasindi futhi oguquguqukayo, osetshenziswa kakhulu ukuphatha umthwalo olula kuye komaphakathi kuzo zonke izimboni. Njengoba igama layo liphakamisa, le crane ifaka umklamo wegirder owodwa, okuyenza yonge futhi isebenze kahle emisebenzini yokuphakamisa izinto ezilula uma iqhathaniswa namamodeli wamagida amabili. Ngokuya ngezidingo zokusebenza, indlela yokuphakamisa ingahlonyiswa ngentambo kagesi yokuphakamisa intambo noma i-hoist yamaketango. Ukuze uvikeleke, isistimu ihlanganisa ukuvikela ukulayisha ngokweqile kanye nokuvikela umkhawulo. Uma i-hoist ifinyelela indawo yayo yomkhawulo ephezulu noma ephansi, uhlelo lokuvikela lunqamula ngokuzenzakalelayo ukunikezwa kwamandla ukuvimbela izingozi nokuqinisekisa ukusebenza okuphephile.
Ukucushwa okuvame kakhulu kwe-crane eyodwa yegirder overhead uhlobo olugijima phezulu, lapho amaloli okugcina ehamba phezulu kwesistimu ye-runway. Kodwa-ke, imiklamo ehlukile efana nama-cranes angaphansi kokusebenza noma ngisho nokucushwa kwama-double girder nayo iyatholakala, enikeza ukuguquguquka ukuze ivumelane nezinsiza ezahlukene kanye nezinhlelo zokusebenza.
Enye yezinzuzo eziyinhloko ze-I-crane eyodwa yegirder ngaphezuluukuphumelela kwayo kwezindleko. Njengoba idinga impahla encane nesikhathi sokwenziwa esifushane uma kuqhathaniswa nama-double girder cranes, ukutshalwa kwezimali kokuqala kuphansi kakhulu kuyilapho kusahlinzeka ngokuphakamisa ukusebenza okuthembekile.
Ungakhetha kanjani i-crane efanele yebhizinisi lakho?
Emkhiqizweni wesimanje, indawo yokugcina impahla kanye nempahla, kanye nezimboni ezinzima,ama-cranes angaphezuluseziphenduke izinto ezibalulekile zokuthuthukisa ukukhiqiza kanye nokuqinisekisa ukusebenza okuphephile. Kodwa-ke, lapho bebhekene nenqwaba yama-cranes emakethe, abanikazi bamabhizinisi abaningi badidekile ngokuthi bangakhetha kanjani ukhreyini webhuloho ofaneleka kakhulu webhizinisi labo.
♦ Ukusula Isimo Sesicelo Nezimfuneko
Okokuqala, kufanele uqonde imboni yebhizinisi lakho kanye nezimo zohlelo lokusebenza. Isibonelo, ukukhiqiza, izimboni zokucubungula insimbi, izitolo zemishini, noma izikhungo zezokuthutha kanye nezindawo zokugcina impahla zonke zinezidingo ezihluke kakhulu zomthamo womthwalo we-crane kanye nemvamisa yokusebenza. Ukucacisa izidingo zakho kuzobeka isisekelo sokukhetha imodeli elandelayo.
♦Ukunquma Amandla Okuphakamisa kanye Nekilasi Lomsebenzi
Lapho ukhetha i-aibhuloho crane, umthamo omkhulu wokuphakamisa uyinto ebaluleke kakhulu. Ngomsebenzi wokukhanya, i-crane yebhuloho elilodwa legirder iyisinqumo esihle. Ukuphakamisa amathani amakhulu noma ama-high-frequency, i-double girder bridge crane kufanele ikhethwe ngesakhiwo sayo esizinzile nempilo ende.
♦ Ukuhlanganisa Izimo Zokwakha Ifekthri
Ubude, ubude besikhathi, kanye nengqalasizinda yethrekhi ekhona yesakhiwo sefekthri inquma ngokuqondile uhlobo lwe-crane yebhuloho ongakhethwa. Isibonelo, ama-workshops anendawo elinganiselwe afaneleka kuma-cranes angaphezulu amisiwe, kuyilapho ama-workshops amakhulu afaneleka kakhulu ekwakhiweni kwe-double girder. Ukucatshangelwa kahle izimo zezitshalo kungagwema ukufakwa nokulungisa izinto ezingadingekile.
♦Gxila ekuphepheni nasezindleleni zokusebenza
Okwesimanjeama-cranes angaphezulu kwegirderkufanele ifakwe amasistimu okuphepha afana nokushintsha imikhawulo, ukuvikela ukugcwala ngokweqile, namadivayisi okucisha ugesi esimweni esiphuthumayo. Ngaphezu kwalokho, kuye ngendawo yokusebenza, isilawuli se-joystick, isilawuli kude esingenantambo, noma ukusebenza kwekhebhu kungakhethwa ukuze kuqinisekiswe ukusebenza kahle nokuphepha.
♦ Ukukhetha umphakeli onokwethenjelwa
Okokugcina, ukuthola umhlinzeki we-crane oqeqeshiwe nonolwazi kubalulekile. Imikhiqizo yekhwalithi ephezulu ehambisana nesevisi ephelele yangemva kokuthengisa iqinisekisa ukusebenza kwesikhathi eside, okuzinzile kwemishini futhi inciphisa ubungozi bokusebenza kwebhizinisi lakho.
Ukukhetha i-overhead crane efanele yebhizinisi lakho kudinga ukucatshangelwa okuphelele kwezidingo zemboni, umthamo wokuphakamisa, izimo zezitshalo, izici zokuphepha, namandla abahlinzeki. Ngokukhetha kuphela i-crane elungile engaphezulu kukagesi ungakwazi ukuzuza ngempela ukusebenza kahle kokukhiqiza okuthuthukisiwe kanye nokulawula izindleko zesikhathi eside.
Kwa-SEVENCRANE, sinikeza ububanzi obubanzi beama-cranes angaphezulu kwegirderyakhelwe ukuhlangabezana nezidingo ezihlukene zezimboni. Ama-cranes ethu aklanyelwe ukuletha ukuqina, ukuphepha, nokusebenza okungaguquki ngisho nangaphansi kwezimo ezinzima. Amakhasimende ethu amaningi ayaqhubeka nokusebenzisa amathuluzi anikezwa eminyakeni engaphezu kwengu-25 edlule, okufakazela ukwethembeka kanye nenani elihlala njalo lemikhiqizo yethu.
Noma ngabe eyezindawo zokusebenzela, izindawo zokugcina izimpahla, noma izinsiza zokukhiqiza, i-single girder overhead crane iyisixazululo esifakazelwe esihlanganisa ukufinyeleleka, ukuphepha, nokusebenza kahle, okuyenza ibe yinketho ekhethwayo kumabhizinisi emhlabeni jikelele.
Ukusikhetha kusho ukukhetha ukuphepha, ukukhiqiza okuphumelelayo, kanye nenani lesikhathi eside. Singaphezu nje komphakeli we-crane; singazakwethu othembekile wokuthuthukisa ibhizinisi lakho. Ukusebenza nathi kusho ukuthi uthola okungaphezu nje kukacrane; uthola isisombululo esibanzi esithuthukisa ukusebenza kahle, esinciphisa izindleko, futhi siqinisekise ukuphepha.
