I-crane yaselwandle luhlobo olukhethekileyo lwe-crane, eyi-crane-duty-duty crane ngokukodwa esetyenziselwa ubunjineli baselwandle, ikakhulu isetyenziselwa imisebenzi eyahlukeneyo enzima, kwaye ineempawu zokusebenza okuphezulu, ukuzinza kunye nokuthembeka.
Ulwakhiwo lwecrane yaselwandle ngokubanzi lubandakanya isakhelo, inkqubo yokubeka indawo, inkqubo yokuqhuba kunye nenkqubo yolawulo.Isakhelo ngumzimba ophambili we-crane, ozinzisa i-crane kunye nokuxhasa amanye amalungu e-crane.Iinkqubo zokumisa zisetyenziselwa ukulinganisa indawo ye-crane kunye nokuguqula ibe ngumqondiso wombane ukubonelela ngempendulo echanekileyo yendawo.Inkqubo yokuqhuba iqulunqwe yimoto, i-hydraulic system kunye ne-transmission system, apho i-motor ikakhulu yenziwe yi-generator, injini, isilawuli kunye nomqhubi.Inkqubo yokulawula isetyenziselwa ukulawula ukuhanjiswa kunye nokubeka i-crane, equka i-sensor, abalawuli, abaqhubi kunye namanye amacandelo.
Iikhreyini zaselwandle zisebenza ngokufanelekileyo, zizinzile, kwaye zithembekile iikhreyini ezinobunzima obunokusebenzisa imithombo eyahlukeneyo yamandla kwaye zibonelele ngeenkonzo zobunjineli bolwandle ezinobume bendalo.
I-crane yase-Offshore luhlobo lwezixhobo ezisetyenziselwa ukuphakamisa kunye nokuhambisa izinto ezinzima ngaphakathi nangaphantsi kwenqanawa.Ezi cranes ziyilelwe ukuba zimelane neemeko ezinzima zaselwandle, kuquka imimoya ebhudla ngamandla, amaza kunye nokudleka kwamanzi anetyuwa.Ngokuqhelekileyo zifakwe kwisiseko okanye kwidekhi kwaye zinokujikeleza iidigri ze-360 ukuququzelela ukulayisha kunye nokukhulula iimpahla.
Iikhreyini zaselunxwemeni ziyafumaneka ngobukhulu obahlukeneyo kunye noyilo, kuxhomekeke kusetyenziso olucetywayo.Ezinye zincinci kwaye ziphathwayo, zenzelwe umsebenzi olula, ngelixa ezinye zikhulu kwaye zinamandla, zikwazi ukuphakamisa ngaphezu kweetoni ze-100 zezinto ezinzima.Zikwaza ngeendlela ezahlukeneyo, kubandakanya i-telescopic, i-knuckle suspenders kunye ne-suspenders esisigxina.
Kutheni iicranes zaselwandle zibalulekile
Ngenxa yezizathu ezininzi, iikhreyini zaselunxwemeni zizixhobo ezibalulekileyo zokusebenza kwe-offshore.Okokuqala, zibalulekile ekulayisheni nasekukhupheni iimpahla ngaphakathi nangaphandle kwenqanawa.Oku kubandakanya yonke into ukusuka kwizikhongozeli kunye neepalethi ukuya kwizixhobo ezinzima kunye nezithuthi.Ukuba akukho crane ye-offshore, iimpahla kuya kufuneka zilayishwe kwaye zothulwe ngesandla, okuya kuthatha ixesha kunye nomsebenzi.
Iikhreyini zaselunxwemeni zikwabalulekile kwimisebenzi ekude nonxweme, kubandakanywa nokuphononongwa kwe-oyile negesi, ukwakhiwa nokugcinwa kwe-offshore.Ezi cranes zingasetyenziselwa ukuphakamisa kunye nokufakela izixhobo ezingaphantsi kolwandle, ukwenza ulondolozo kumaqonga angaphesheya, kunye nezixhobo zokuthutha kunye nezixhobo ukuya nokubuya kwiindawo ezikude nonxweme.
Esinye isizathu esibalulekileyo seecranes zaselwandle kukukwazi kwabo ukuphucula ukhuseleko.Ngama-cranes ase-offshore, abaqhubi banokuphakamisa ngokukhuselekileyo kwaye bahambise izinto ezinzima ngaphandle kokwenza ingozi kubo okanye kwabanye.Oku kunciphisa umngcipheko wokulimala, iingozi kunye nokulimala kwempahla okanye iinqanawa.
Iindidi ezahlukeneyo zeekhreyini zaselwandle
Njengoko kukhankanyiwe ngaphambili, kukho iintlobo ezahlukeneyo zeekrane zaselwandle, nganye kuzo ineempawu zayo kunye nemisebenzi.Ezona ntlobo zixhaphakileyo zeekhreyini zaselunxwemeni ziquka:
I-Telescopic crane - Ikhreyini ine-hydraulic boom erhoxiswayo eyivumela ukuba ifikelele kumgama omkhulu.Ngokuqhelekileyo isetyenziselwa ukulayisha kunye nokukhulula iimpahla.
I-Knuckle jib crane - Le crane inoluhlu lweejibs ezidibeneyo ezinokugoba njengeqhosha lokuphakamisa izinto phezu kwemiqobo.Kushishino lokuloba kudla ngokusetyenziswa ukunyusela iminatha yokuloba enqanaweni naphantsi kwenqanawa.
Fixed boom crane - i-crane ine-boom esisigxina engenakususwa;Nangona kunjalo, inokujikeleza i-360 degrees.Idla ngokusetyenziswa kwishishini leoli kunye negesi ukuphakamisa izixhobo ezinzima kunye nokubonelela kwiiplatifti ezikude nonxweme.
Ukuqukumbela
I-crane ye-Offshore sisixhobo esibalulekileyo ekusebenzeni kwe-offshore.Ukusuka ekulayisheni nasekukhupheni iimpahla ukuya kwimisebenzi yangaphandle, ezi cranes zidlala indima ebalulekileyo kukhuseleko kunye nokusebenza kakuhle kwemisebenzi ye-offshore.Kukho iintlobo ezahlukeneyo zeekrane zaselwandle, nganye ineempawu zayo kunye nemisebenzi ekhethekileyo, ngoko kubaluleke kakhulu ukukhetha i-crane efanelekileyo yokusebenza.Ukuba ufuna i-crane yolwandle, nceda uqinisekise ukusebenzisana nabanikezeli abathembekileyo, abanokukunceda ukhethe i-crane efanelekileyo kwiimfuno zakho.
