Kutheni iiJib Cranes zithandwa kangaka?
Iikhrayini zeJib zifumene udumo olukhulu kumashishini ahlukeneyo ngenxa yeenzuzo zazo ezininzi kunye nokuguquguquka kwazo. Ezi khrayini zisetyenziswa kakhulu ukuphakamisa, ukuhambisa, kunye nokubeka imithwalo enzima kwiintlobo ngeentlobo zezicelo. Kukho iintlobo ezimbini eziphambili zeekhrayini zejib - ezifakwe phantsi kunye nezifakwe eludongeni. Zombini ezi ntlobo zineempawu ezizodwa ezenza zilungele iimeko kunye neemfuno ezahlukeneyo. Kweli nqaku, siza kuhlalutya iikhrayini zejib ngokweenkcukacha, sigqamise iingenelo zazo kunye nokuguquguquka kwazo, ukuze sichaze isizathu sokuba zithandwa kangaka.
Iikhreyini zeJib, nokuba zifakelwe kumgangatho okanye eludongeni, zibonelela ngeenzuzo ezininzi ezibalulekileyo ezinegalelo ekusetyenzisweni kwazo ngokubanzi. Okokuqala, uyilo lwazo olulula kunye nolwakhiwo lwazo lwenza kube lula ukuzifaka nokuzigcina zisemgangathweni, nto leyo ebangela ukuba iindleko zinciphe kwaye imveliso inyuke. Xa kuthelekiswa nezinye iintlobo zeekhreyini, ezifana neekhreyini eziphezulu, iikhreyini zeJib zingabizi kakhulu kwaye zifuna indawo encinci. Oku kuzenza zibe lukhetho olufanelekileyo kwiindawo ezinendawo encinci apho ukukwazi ukuhamba kubaluleke kakhulu.
Enye inzuzo ebalulekileyo yee-jib cranes kukukwazi kwazo ukuphatha imithwalo enzima ngokulula. Ukuqina kwesakhiwo kunye nokuzinza kwezi cranes kuvumela ukuba ziphakamise kwaye zihambise izinto ezinzima ngokufanelekileyo. Ngaphezu koko, ii-jib cranes zibonelela ngolawulo oluhle kunye nokuhamba kakuhle, ukuqinisekisa indawo echanekileyo yemithwalo. Olu phawu luluncedo ngakumbi kumashishini okuvelisa nokwakha apho ukuchaneka kunye nokhuseleko kubaluleke kakhulu.
Ukuguquguquka yenye into ebalulekileyo enegalelo ekuthandweni kwee-jib cranes. Ezi cranes zinokwenziwa ngokwezifiso ukuhlangabezana neemfuno ezithile, nto leyo ezenza zifaneleke kwiintlobo ngeentlobo zezicelo. Umzekelo, ii-jib cranes ezifakwe phantsi zisetyenziswa kakhulu kwiindawo zoshishino, njengeendawo zokugcina impahla kunye nemigca yokuhlanganisa, apho imithwalo enzima kufuneka ihanjiswe ngokuthe tye. Kwelinye icala, ii-jib cranes ezifakwe eludongeni zilungele iindawo ezixineneyo apho indawo yomgangatho incinci. Zisetyenziswa kakhulu kwiindawo zokusebenzela, kwiigaraji, nakwiiyunithi ezincinci zokuvelisa.
Ukongeza ekubeni zisebenza ngeendlela ezahlukeneyo, ii-jib cranes zibonelela ngeendlela ezahlukeneyo zokuphakamisa ukuze zihlangabezane neemfuno ezithile. Zinokuxhotyiswa ngeentlobo ezahlukeneyo zee-hoists, ezifana nee-electric chain hoists okanye ii-wire rope hoists, kuxhomekeke kubunzima kunye nobukhulu bemithwalo eza kuphakanyiswa. Oku kuguquguquka kuvumela ii-jib cranes ukuba ziphathe uluhlu olubanzi lwezixhobo, ukusuka kwizinto ezincinci ukuya koomatshini abakhulu.
Iikhrayini zeJib zikwaphucula ukhuseleko kwindawo yokusebenza ngokunciphisa umngcipheko weengozi kunye nokwenzakala. Uyilo lwazo oluncinci lunciphisa amathuba okungqubana nezinye izixhobo okanye izakhiwo, okuqinisekisa indawo yokusebenza ekhuselekileyo. Ukongeza, iikhrayini zeJib zinokuxhotyiswa ngeempawu zokhuseleko ezifana nokutshintsha umda, ukhuseleko lokugqithisa, kunye namaqhosha okuma ngexesha likaxakeka, okuphucula ngakumbi amandla azo okhuseleko.
Ukuqukumbela, ii-jib cranes, nokuba zifakelwe emgangathweni okanye eludongeni, zithandwa kakhulu ngenxa yeenzuzo zazo ezininzi kunye nokuguquguquka kwazo. Uyilo lwazo oluthe ngqo, ukonga iindleko, kunye nokulula kokufakwa kwazo kuzenza zibe lukhetho olunomtsalane kumashishini amaninzi. Ukukwazi ukuphatha imithwalo enzima, ulawulo oluchanekileyo, kunye neendlela zokwenza ngokwezifiso kongeza kuncedo ekusetyenzisweni kwazo ngokubanzi. Ngaphezu koko, ii-jib cranes ziqinisekisa ukhuseleko kwindawo yokusebenza ngokunciphisa umngcipheko weengozi kunye nokwenzakala. Xa sijonga ezi zinto, kuyacaca ukuba kutheni ii-jib cranes ziqhubeka nokuba lukhetho olukhethwayo kwizicelo ezahlukeneyo, nto leyo ezenza zibe sisixhobo esibalulekileyo kwindalo yanamhlanje yemizi-mveliso.
