I-Flexible Rubber Tyred Gantry Crane for Port Operations

I-gantry crane (i-RTG crane) ingumshini okhethekile wokubamba iziqukathi osetshenziswa kakhulu emachwebeni, ezikhumulweni zamabhokisi, kumayadi kaloliwe, nasezindaweni ezinkulu zezimpahla. Idizayinelwe ihambisana nokuvumelana nezimo engqondweni, i-gantry crane enerabha enamathayi enjoloba ihamba ngamathayi enjoloba ahlala isikhathi eside esikhundleni sojantshi abangaguquki, okuwuvumela ukuba uhambe ngokukhululeka ezindaweni ezihlukahlukene zokusebenza futhi uvumelane nezimo ezihlukahlukene zokusebenza. Lokhu kuyenza ibe ucezu lwesisetshenziswa esibalulekile sokupakisha, ukulayisha, kanye nokuthulula iziqukathi ezijwayelekile ezifana namayunithi angama-20ft, 40ft, kanye namayunithi angama-45ft ngokunemba okuphezulu nokusebenza kahle.

Isakhiwo se-gantry crane enamathayi erabha ngokuvamile sihlanganisa uhlaka lwensimbi lwe-gantry, inqola enezinto zokuphakamisa, kanye nesisakazeli sokuphakamisa isiqukathi. I-trolley ihamba eduze kwe-gantry beam, ivumela i-crane ukuthi iphakamise futhi ibeke iziqukathi emigqeni eminingi nokuphakama. Amamodeli athuthukile angapakisha iziqukathi ezifika kweziyisithupha noma eziyisikhombisa ukuphakama futhi zinqamule imigqa eminingi, okwandisa ukusetshenziswa kwendawo yasegcekeni. Ngamandla okuphakamisa asukela emashumini kuya kumakhulu amathani, i-RTG crane iyakwazi ukuphatha izimfuno ezinzima zezinto zesimanjemanje.

Enye yezinzuzo ezibalulekile ze-gantry crane ethayiwe yirabha ukuhamba kwayo. Ifakwe izindlela eziningi zokuqondisa-njengokuhamba okuqondile, ukunyakaza kwe-oblique, kanye nokuqondisa kwe-90-degree-i-crane ingakwazi ukuzulazula kalula ezindaweni eziwumngcingo, ijikeleze endaweni, futhi ivumelane nezakhiwo zegceke eziyinkimbinkimbi. Lokhu kuyenza ifaneleke ikakhulukazi amatheminali aminyene lapho ukuguquguquka nokunemba kubalulekile.

Ama-gantry cranes esimanje anethayi lerabha nawo aklanywe ngokusebenza kahle kwamandla nokuphepha engqondweni. Abaningi bamukela amasistimu kagesi noma ama-hybrid drive anokulawula imvamisa okuguquguqukayo, ubuchwepheshe bokutholwa kwamandla, nezici zokuqapha ezihlakaniphile. Ukuphepha kuthuthukiswa ngamasistimu amelene ne-sway, ukuvikela ukugcwala ngokweqile, nemisebenzi yokumisa okuzenzakalelayo, ukuqinisekisa ukuphathwa okuphephile nokusebenza kahle kweziqukathi.

Kafushane, i-gantry crane ethayiwe yerabha ihlanganisa amandla okuphakamisa umsebenzi osindayo, ukuguquguquka okuphakeme, nokusebenza okuhlakaniphile ukuze ilethe ukusebenza okuvelele ezindaweni zechweba nezokuthutha. Ikhono layo lokuphatha umthamo omkhulu weziqukathi ngendlela efanele liyenza ibe yinsika yemisebenzi yohwebo emhlabeni wonke kanye nethuluzi elibalulekile lezindawo zesimanje zokuthutha ezihamba phakathi kwezinhlobo ezahlukene.

♦ Isakhiwo Se-Crane Esikhulu: I-gantry crane enerabha enamathayi erabha, evame ukubizwa ngokuthi i-gantry crane esindayo, yakhiwe ngohlaka lwensimbi oluqinile olunikeza isisekelo sokuphakamisa nokuhambisa iziqukathi. Lesi sakhiwo esiyinhloko sisekela indlela yokuphakamisa futhi siqinisekisa ukuqina ngaphansi kwezimo zokusebenza ezinzima.

♦ Amasondo Namathayi: Njengoba ifakwe amathayi enjoloba amakhulu, u-crane ungahamba ezindaweni ezihlukahlukene, okuhlanganisa ukhonkolo, itiyela, namayadi esitsha. Lawa masondo enza i-crane ihambe kahle kakhulu, ngokungafani nama-cranes agibele kajantshi, futhi ayenza ilungele ukusebenza kwechweba eliguquguqukayo.

♦Ama-ekseli kanye nohlelo lokumiswa: Ukuphatha isisindo sakho kokubili iziqukathi ze-crane nezisindayo, ama-ekseli nokumiswa kusabalalisa imithwalo ngokulinganayo futhi kugcinwe ibhalansi. Lokhu kuqinisekisa ukusebenza kahle ngisho nalapho i-crane yenza imijikelezo yokuphakamisa eqhubekayo kumatheminali amatasa.

♦ I-Telescopic Boom: Ama-gantry cranes amaningi anamathayela erabha ahlanganisa i-telescopic boom yokupakisha nokukhipha iziqukathi. Le ngxenye enwebekayo ivumela i-crane ukuthi ilungise ubude futhi ifinyelele, ikwenze kube nokwenzeka ukuphatha kahle imigqa eminingi yeziqukathi ezistakiwe.

♦ Uhlelo Lokusakaza: I-spreader, exhunywe kumshini wokuphakamisa, ibamba iziqukathi ngokuphepha ngesikhathi sokuphakamisa. Amamodeli athuthukisiwe ama-gantry cranes asebenza kanzima asebenzisa izisakazi ezizenzakalelayo ezilungisa amasayizi esiqukathi esijwayelekile, athuthukisa ukuphepha nokusebenza kahle.

♦Isistimu Yokulawula: Ikhreyini yesimanje ye-RTG ifakwe isistimu yokulawula ehlakaniphile, ngokuvamile esekelwe ku-PLC, evumela ukuqondisa okunembayo, ukuzungezisa, nokupakisha. Izici ezizenzakalelayo zinciphisa umsebenzi womsebenzisi futhi zithuthukisa ukukhiqizwa kwegceke lesitsha.

♦ Izindlela Zokusekela Nokuphepha Kwaphansi: I-crane isebenza ngokusekelwa okwengeziwe komhlabathi, okuhlanganisa izinto zokuzinzisa kanye nama-container pads. Amasistimu okuphepha afana nama-alamu, izinzwa, nezitobhi eziphuthumayo zakhelwe ngaphakathi ukuze kunqandwe izingozi futhi kuvikelwe kokubili abaqhubi namathuluzi.

Kafushane, i-gantry crane ethayiwe yerabha iwuhlobo olukhethekile lwe-heavy duty gantry crane eklanyelwe amatheminali esitsha kanye nezindawo zemikhumbi. Ngezingxenye zayo ezinokwethenjelwa kanye nezinhlelo ezithuthukisiwe, iqinisekisa ukuphathwa okusebenzayo, okuphephile, nokuguquguqukayo kweziqukathi ku-logistics yomhlaba wonke.
