Gantry lift imagwiritsidwa ntchito kwambiri mumigodi, kupanga wamba, konkire, zomangamanga, komanso malo otsegulira otsegula ndi malo osungiramo katundu kuti azitha kunyamula katundu wambiri. Single-girder gantry crane nthawi zambiri imadziwika kuti ndi mtundu wopepuka wa gantry crane chifukwa cha kapangidwe kake ndi mtengo umodzi wokha, imagwiritsidwa ntchito kwambiri pamalo otseguka ngati mayadi a zida, malo ogwirira ntchito, malo osungiramo katundu ndikutsitsa. Single-girder gantry crane ndi crane wamba yomwe imapangidwira kuti igwire zinthu zonse, zomwe zimagwiritsidwa ntchito panja, malo osungiramo zinthu, madoko, mafakitale a granite, mafakitale a simenti, mabwalo otseguka, malo osungiramo ziwiya, malo osungiramo zombo, ndi zina zambiri. Komabe, ndizoletsedwa kugwira zitsulo zosungunuka, zoyaka, kapena zophulika. Box-type single-girder gantry crane ndi yapakatikati, yoyenda panjira, nthawi zambiri imakhala ndi chonyamulira chamagetsi cha MD ngati chonyamulira, chokhala ndi chonyamulira chamagetsi chodutsa pachitsulo chotsika cha I-chitsulo chotchingira chachikulu, chopangidwa ndi mbale yachitsulo. , yomwe imapangidwa kuchokera ku mbale yachitsulo, monga C-chitsulo, ndi insulating zitsulo mbale, ndi I-zitsulo.
SEVENCRANE imapereka mitundu yosiyanasiyana ya gantry lift, monga, kumaliza ndi theka lathunthu malinga ndi mapangidwe a phazi, gantry ya chidebe, gantry yosungiramo zinthu, dockside gantry, dockside gantry, dockside gantry, dockside gantry, potengera ntchito. Kuphatikiza pa ma cranes omwe atchulidwa pamwambapa, SEVENCRAN -E imapanga ndikupanga ma cranes osiyanasiyana amtundu umodzi wogwiritsa ntchito m'mafakitale osiyanasiyana, kuphatikiza ma gantry amtundu wa rabara wamtundu umodzi wamagetsi ndi ma hydraulic.
Akapangidwa moyenera, ma cranes a single girder amatha kukulitsa kupanga tsiku ndi tsiku, kupereka njira yabwino yothetsera zida ndi ntchito zomwe zili ndi malo ochepa pansi komanso zofunikira zapamtunda wa crane yopepuka mpaka yapakatikati. Chifukwa amangofunika mtengo umodzi kuti adutse, makinawa nthawi zambiri amakhala ndi kulemera kochepa, kutanthauza kuti amatha kugwiritsa ntchito njira zopepuka ndikulumikizana ndi nyumba zomwe zilipo kale. Kumanga ma cranes apansi-pansi amalola makina a trunnion, momwe kusamutsa katundu kumafunikira kuchokera ku bay kupita kwina, mwina kusamutsidwa ku monorails, ndiyeno ku crane ina, kapena pakuwombera.
