SEVENCRANE ndi gulu lotsogola la China la crane mabizinesi omwe adakhazikitsidwa mu 1995, ndikutumikira makasitomala ambiri padziko lonse lapansi kuti apereke projekiti yathunthu yokweza, kuphatikiza Gantry crane, Bridge crane, Jib crane, Accessory. a). SEVENCRANE adalandira kale ziphaso za CCC, CE, BV, SGS, ISOOHSAS ndipo wapambana ulemu wopitilira 60. b). Kampani yathu imapereka ntchito kumakampani opitilira 5000, ndipo zogulitsa ziliotchuka m'mayiko oposa 100. Crane ya jib ndiyotchuka kwambiri m'mafakitale ambiri. Ndi njira zingapo zokonzera jib pakhoma kapena pansi, ndi mitundu yosiyanasiyana ya hoist yomwe ilipo, imagwirizana bwino ndi zida zosiyanasiyana. Thema cranes a pillar jibkukhala ndi katundu wolemera mpaka 2,000kg ndi kuyenda kowombera komwe kungafikire madigiri a 300 ndi pillar jib, ndi madigiri a 270 okhala ndi jib yomangidwa ndi khoma.
Thepillar jib craneadapangidwa kuti aziyika momasuka panyumba yomanga. Crane yogwirira ntchito iyi imapereka mitundu yokwana 270° ndi jib mkono wautali mpaka 7 m ndi Safe Working Loads (SWL) mpaka 1.0 t. Zoyimitsa zoyimitsa zimakupatsani mwayi wosinthira masinthidwe kuti agwirizane ndi zosowa zanu.
Thendime yokhazikika jib cranenthawi zambiri amagwiritsidwa ntchito kuthandizira kukweza ntchito zomwe nthawi zambiri zimakhala zocheperako. Katundu amatha kukwezedwa mwachangu komanso mosatekeseka ndipo amatha kusamutsidwa mosavutikira komanso ndendende chifukwa cha mkono woyenda bwino wa jib.
Pamwamba pa mzere woyimirira amaperekedwa ndi chithandizo chozungulira komansokusinthasintha kuzungulira.
Mzere woyimirira umapangidwa ndi chubu chachitsulo chosasunthika, kulemera kopepuka, kulimba kwakukulu, katundu wamkulu.
Wwalo lapadera la nayiloni laukadaulo lokhala ndi mayendedwe ogudubuza limatengedwa, kukangana kochepa komanso kusinthasintha.
Zochepa kapangidwe, zosavuta opaleshoni, ndi a zosiyanasiyana chokweza magetsi. Thepillar jib craneikhoza kukhala ndi zingwe zokweza chingwe chamagetsi, ma chain chain hoists kapena ma hoist apamanja. Kuchita bwino, kapangidwe koyenera,ntchito yapamwamba kuchita bwino, kupulumutsa nthawi ndi khama.
