Isikebhe jib craneszibalulekile ezinhlobonhlobo zezicelo zasolwandle, imikhumbi yokuphakamisa, imishini esindayo nezinye izinto ngokuphepha nangempumelelo. Zenzelwe ngqo izidingo zokusebenza zezindawo ezihamba emanzini, amadokhi kanye nezindawo zemikhumbi. Banikeza izinzuzo eziyingqayizivele ekuhambeni, ukusebenza kalula nokuzivumelanisa nezimo, okusiza ukunciphisa isikhathi sokuphatha ngenkathi kuthuthukisa ukuphepha nokunemba.
Izici eziyinhloko zama-cranes we-boat jib
Idizayini eqinile, yokonga isikhala.Ama-cranes asolwandlezivame ukugxunyekwa ezisekelweni ezigxilile, izinsika noma ngisho nezikhumulo ezintantayo, okuzenza zifanelekele izindawo ezinendawo elinganiselwe. Idizayini yabo inciphisa umkhondo, ivumela ukusebenza kahle ezindaweni eziqinile njengamadokhi, amadokhi noma izindawo zemikhumbi.
Amandla okuphakamisa aphezulu. Naphezu kokwakheka kwazo okuhlangene,ama-marine jib cranesaklanyelwe ukuphakamisa izisindo ezinkulu, namandla okuphakamisa asukela kumathani ambalwa kuya emashumini amathani. Lolu hlu luvumela abaqhubi ukuthi baphathe imikhumbi ehlukahlukene, kusukela ezikebheni zokungcebeleka ezincane ukuya emikhunjini emikhulu yezohwebo, ngendlela elawulwayo futhi ezinzile.
Ukuqina nokumelana nokugqwala. Ngenxa yokuthi lawa ma-cranes asebenza ezindaweni ezisogwini noma olwandle, avame ukwakhiwa ngezinto ezimelana nokugqwala njengensimbi ewuthayela noma insimbi engagqwali futhi avame ukumbozwa ngesimbozo esivikela isimo sezulu. Lezi zinto zivimbela ukugqwala nokugqwala kwamanzi anosawoti, okuqinisekisa ukwethembeka kwesikhathi eside.
Lapho ukhetha i-ai-jib crane ebulalayo, izici ezimbalwa okufanele zicatshangelwe ukuze kuhlangatshezwane nezidingo ezithile zokusebenza:
Umthamo wesisindo nokufinyelela: Umthamo omkhulu wokulayisha we-crane nokufinyelela kufanele kuhambisane nosayizi nohlobo lomkhumbi noma okokusebenza ezowuphatha.
Umthombo wamandla: Ama-cranes amaningi ama-slewing jib anikwa amandla kagesi ukuze asebenze ngokuthula, okungakhiphi, kanti amanye angase asebenzise amasistimu asebenza ngamanzi ukukhulisa amandla okuphakamisa.
Amasistimu okulawula: Amanye amamodeli anikezela ngesilawuli kude noma amasistimu ezishintshayo ukuze aqondise ukuqondiswa okunembayo. Lezi zici zandisa ukuphepha futhi zenza kube lula ku-opharetha ukulawula u-crane, ngisho nasesimweni sezulu esingesihle.
Isikebhe jib craneshlinzeka ngesixazululo esisebenzayo, esiguquguqukayo sokuphakamisa imisebenzi yasolwandle neyedokhu. Ngokuqonda izici zabo, izinhlelo zokusebenza, nokucatshangelwa kwedizayini, ungakhetha i-crane evumelana kangcono nezidingo zakho zokuphakamisa okuthile.
