Ma crane a Jib amatchedwanso ma crane a cantilever, omwe amatha kugwiritsidwa ntchito momasuka m'malo atatu, ndipo amagwiritsidwa ntchito kwambiri m'malo osiyanasiyana m'mafakitale osiyanasiyana pakakhala mtunda wautali komanso mayendedwe ovuta.
Kreniyo imapangidwa ndi mzati, chipangizo choyendetsera mkono chodulira ndi chokwezera chamagetsi. Mapeto a mzatiwo amakhazikika pa maziko a konkire kudzera m'mabotolo oteteza. Mkonowo umayenda pa I-beam molunjika kuchokera kumanzere kupita kumanja ndipo umanyamula zinthu zolemera. Gawo la crane ndi kapangidwe ka chitsulo chopanda kanthu kolemera, kutalika kwakukulu, mphamvu yayikulu yonyamula, yotsika mtengo komanso yolimba.
Ma crane a Jib ndi ofunikira kwambiri pakupanga kulikonse komwe kumafuna liwiro, kulondola, komanso nthawi yochepa yogwira ntchito. Opangidwa kuti azitha kugwiritsidwa ntchito mosavuta, ndi osinthika, olimba, ndipo amagwira ntchito pafupifupi mtundu uliwonse wa malo ogwirira ntchito, amapereka chithandizo cha ma crane opitilira pamwamba pa mizere yopangira, komanso amathandiza kuti ma terminal, ma machining cell, ndi malo osungiramo zinthu azigwira ntchito bwino.
Ndi njira zosiyanasiyana zomangira jib pakhoma kapena pansi, komanso mitundu yosiyanasiyana ya zokweza, zimagwirizana bwino ndi zinthu zosiyanasiyana. Ma cranes ali ndi mphamvu yonyamula katundu yokwana 2,000 kg komanso kuyenda kodulira komwe kumatha kufika madigiri 300 ndi pillar jib, ndi madigiri 270 ndi jib yomangiriridwa pakhoma.
