Xa kufikwa ekuhambiseni izinto kwindawo yokugcina impahla okanye kwindawo yemizi-mveliso, ii-jib cranes zizixhobo ezibalulekileyo. Kukho iintlobo ezimbini eziphambili ze-jib crane, kuquka ii-jib cranes ezifakwe kwisiseko kunye nee-jib cranes ezingenasiseko. Zombini zineengenelo kunye neengxaki zazo, kwaye ukhetho ekugqibeleni luxhomekeke kwiimfuno ezithile zeprojekthi.
Iikhreyini ze-jib ezifakwe kumgangatho wesiseko zenzelwe ukuxhonywa kumgangatho. Zinesiseko esomeleleyo esinamathele kumgangatho kwaye zingasetyenziselwa ukuphakamisa nokuhambisa izinto ezijikeleze indawo. Ezi khreyini zaziwa ngokuqina kwazo nokuzinza, nto leyo eyenza ukuba zibe lukhetho oludumileyo kwizicelo ezinzima.iikhreyini zejibingasetyenziselwa ukuhambisa izinto ngendlela ejikelezayo, nto leyo eyenza zilungele iindawo ezinendawo encinci.
Kwelinye icala, ii-crane ze-floor jib cranes ezingenasiseko zenzelwe ukuba zithwalwe. Ezi crane azinanyatheliswa emgangathweni, nto leyo ethetha ukuba zinokufuduselwa kwiindawo ezahlukeneyo njengoko kufuneka. Zihlala zisetyenziselwa imisebenzi elula kwaye zinokufuduselwa lula kwindawo ethile. Ii-crane ze-floor jib cranes ezingenasiseko zihlala zibiza kancinci kunee-crane ezifakwe emgangathweni, nto leyo eyenza zibe lukhetho oludumileyo kumashishini amancinci okanye lawo abhajethi encinci.
Zombini ezi ntlobo zeekhreyini zineengenelo kunye neengxaki zazo. Iikhreyini ezifakwe emgangathweni zibonelela ngozinzo kunye nokuqina, nto leyo eyenza ukuba zibe lukhetho oluhle kwiindlela ezinzima. Nangona kunjalo, aziphatheki lula njengeekreyini ezingenasiseko. Iikhreyini ezingenasiseko, kwelinye icala, ziyaphatheka lula kwaye ziguquguquka, nto leyo eyenza ukuba zibe lukhetho oluhle kwiindlela ezilula okanye kumashishini aphantsi kohlahlo lwabiwo-mali.
Ukuqukumbela, ukhetho phakathi kweekhreyini zejib ezifakwe kwisiseko kunye neekhreyini zejib ezingenasiseko luxhomekeke kwiimfuno ezithile zeprojekthi. Zombini ezi ntlobo zeekhreyini zineengenelo zazo ezikhethekileyo, kwaye kubalulekile ukuqwalasela ezi zinto ngaphambi kokuba wenze isigqibo.
