Mu makampani ambiri opanga, kufunika kusunga otaya zipangizo, kuchokera zipangizo kuti processing, ndiyeno kuti ma CD ndi zoyendera, mosasamala kanthu za kusokonezedwa ndondomeko, zidzachititsa zotayika kupanga, kusankha bwino kukweza zida adzakhala abwino kusunga kampani ambiri kupanga ndondomeko mu khola ndi yosalala boma.
SEVENCRANE imapereka ma crane osiyanasiyana makonda, kupanga ndi kupanga, monga crane ya mlatho, crane ya monorail, crane yonyamula, jib crane, crane ya gantry, ndi zina zambiri, kuti titsimikizire kukhazikika pakukonza ndi kupanga chitetezo, timagwiritsa ntchito ukadaulo wosinthira pafupipafupi komanso kuletsa ukadaulo wa swing pa crane.
Amapangidwa makamaka ndi mtengo waukulu, mtengo wapansi, outrigger, njanji yothamanga, gawo lamagetsi, hoist ndi mbali zina.
Ma crane okhala ndi njanji amaphatikiza ma cantilever single gantry cranes, single cantilever single gantry cranes, single gantry cranes opanda cantilevers.
Mbali ya single girder gantry crane
1. Sitima yokwera njanji ya gantry ili ndi dongosolo losavuta, ntchito yabwino, kupanga ndi kukhazikitsa. Zambiri mwazitsulo zazikuluzikulu zimakhala mafelemu ooneka ngati bokosi. Poyerekeza ndi mtundu wapawiri waukulu wamtengo wapakhomo, kuuma kwathunthu kumakhala kofooka.
2. Malinga ndi ntchito zosiyanasiyana, zida zoteteza mochulukira zitha kugawidwa m'mitundu iwiri: mtundu wotsekera zokha ndi mtundu wathunthu. Malinga ndi kapangidwe kake, amagawidwa kukhala mtundu wamagetsi ndi mtundu wamakina.
Nthawi zonse, sizingagwire ntchito m'malo omwe ali ndi zida zoyaka komanso zophulika. Komanso sizigwira ntchito poizoni ndi pansi ndi kulamulira zipinda ntchito. Ngati mukufuna kugwiritsa ntchito malo apadera, muyenera kudziwitsa wopanga kuti asinthe zinthu zapadera pogula.
3. Single girder gantry crane ili ndi mawonekedwe apamwamba ogwiritsira ntchito malo, kuchuluka kwa magwiridwe antchito, kusinthasintha kwakukulu komanso kusinthasintha kwamphamvu, ndipo imagwiritsidwa ntchito kwambiri pamayadi onyamula katundu. Woyendetsa galimotoyo akakana kukweza chinthucho chifukwa cholemera kwambiri, wolamulirayo ayenera kuchitapo kanthu kuti achepetse katunduyo, ndipo sikuloledwa kukulitsa ntchito ya craneyo.
4. Chingwe chokwera njanji chiyenera kukhala ndi njira yokwezera, ndi zina zotero. Njira yokwezera ndiyo njira yoyambira yogwirira ntchito ya crane. Makina ake okweza nthawi zambiri amakhala CD kapena MD mtundu wamagetsi okweza.
