Idizayini eyenziwe ngokwezifiso yethula i-gantry crane yokwakha ibhuloho

I-girder gantry crane eyethulayo, umshini wokuphakamisa onamandla futhi oguquguqukayo, isiphenduke ithuluzi elibalulekile embonini yezokwakha.Inhloso yawo eyinhloko ukusiza ekwakheni kanyeukufakwa kwamabhuloho, ama-viaducts, nothelawayeka ophakeme.Lo khreni udlala indima ebalulekile ekuphakamiseni ngokuphepha izingxenye zesakhiwo esindayo, njengamabhande kakhonkolo wangaphambili, futhi uzibeke kahle ezindaweni ezimisiwe.

Manje, ake sihlole izici zesakhiwo ezenza i-girder gantry crane ivelele emhlabeni wokwakha.Emgogodleni walo crane kunohlaka oluqinile olunikeza ukuzinza nokusekelwa ngesikhathi sokuphakanyiswa kwemisebenzi.Lolu hlaka luvame ukwenziwa ngensimbi yekhwalithi ephezulu, eqinisekisa amandla amakhulu nokuqina.Iqukethe amakholomu aqondile, amabhande avundlile, kanye ne-diagonal bracing, konke okuklanywe ngobunono ukuze imelane nemithwalo esindayo futhi kugcinwe ukuzinza ngaphansi kwezimo ezimbi.

Esinye sezici eziphawulekayo ze-launch girder gantry crane amathrekhi ayo alungisekayo.Lawa mathrekhi, atholakala ezinhlangothini zombili ze-crane, avumela ukunyakaza okulula endaweni yokwakha.Ngokukwazi ukunweba noma ukuhlehla, i-crane ingakwazi ukuzivumelanisa nezikhala zamabhuloho ahlukahlukene, iqinisekise ukuma okuhle ngesikhathi senqubo yokuphakamisa.Lokhu kulungiswa kubaluleke kakhulu lapho kwenziwa amaphrojekthi wokwakha ayinkimbinkimbi ngamajiyometri ahlukahlukene.

Ukusekela umsebenzi wokuphakamisa, i-crane isebenzisa izindlela ezimbalwa zokuphakamisa.Indlela yokuphakamisa eyinhloko imvamisa iwuhlelo lukajekhi we-hydraulic, oluhlinzeka ngamandla adingekayo ukuze kukhuliswe izinto ezisindayo ze-precast.Lawa ojeke abekwe ngendlela efanele eduze kwebhande elikhulu, okuvumela ukusatshalaliswa kwemithwalo efanayo ngesikhathi sokuphakanyiswa.Ukwengeza, i-crane ifakwe izinto ezisizayo ezifana nezinto eziphumayo neziqinisi, ezithuthukisa ukuzinza futhi zinciphise noma yikuphi ukushwibeka noma ukutsheka okungenzeka phakathi nenqubo yokuphakamisa.

Ukuphepha kubaluleke kakhulu kunoma iyiphi iphrojekthi yokwakha, futhi i-launch girder gantry crane nayo ihlukile.Ngakho, ifakwe izinto eziningi zokuphepha.Lokhu kufaka phakathi ukushintsha komkhawulo, izinkinobho zokumisa izimo eziphuthumayo, namasistimu okuvikela ukugcwala ngokweqile.Lezi zinyathelo ziqinisekisa ukuthi i-crane isebenza ngaphakathi komthamo wayo oshiwo futhi ivimbela noma yiziphi izingozi ezingaba khona noma umonakalo ngenxa yokugcwala ngokweqile.Ngaphezu kwalokho, i-crane iklanywe ngamadivayisi aphikisana ne-tipping kanye nezinzwa zesivinini somoya ukubhekana nezimo zezulu ezimbi, ngokuqhubekayo ukuqinisekisa ukuphepha kwabo bobabili abasebenzi nendawo yokwakha.
