Ma crane a gantry otayidwa ndi mphira(RTG cranes) ndi zida zofunika m'malo osungiramo zinthu, mayadi a mafakitale, ndi malo osungiramo zinthu zazikulu. Zopangidwa kuti zinyamule ndi kunyamula katundu wolemetsa ndi kusinthasintha kwakukulu, ma cranes awa amapereka kuyenda komanso kuchita bwino m'malo osiyanasiyana. Ndiwothandiza makamaka posunga zotengera zotayidwa, makina akuluakulu, ndi zida zina zolemetsa. M'nkhaniyi, tikambirana za makina opangira mphira, zinthu zomwe zimakhudza mtengo wawo, komanso ubwino wawo wonse pamafakitale.
♦ Kukweza Mphamvu: Chimodzi mwazinthu zazikulu zomwe zimakhudza mtengo wa amphira matayala gantry cranendi mphamvu yake yokweza. Ma Crane okhala ndi mphamvu zapamwamba amafunikira zida zomangika zolimba, ma mota amphamvu kwambiri, ndi zina zowonjezera chitetezo. Mwachitsanzo, crane ya matani 50 yomwe imamangidwa kuti izitha kunyamula katundu wolemera kwambiri idzakhala yokwera mtengo kwambiri kuposa yaing'ono yomwe idapangidwira kuti ikhale yopepuka. Momwemonso, ma cranes olemetsa omwe amagwiritsidwa ntchito m'zitsulo kapena madoko otumizira amafunikira zida zolimbitsidwa, zomwe zimawonjezera mtengo wopanga ndi kukonza.
♦Span ndi Kukwezera Utali: Kutalika kwa crane - mtunda wapakati pa miyendo yake - komanso kutalika kwake kokwera kumakhudzanso mtengo wake. Crane yokhala ndi chiwongolero chokulirapo imapereka mwayi wofikira madera ambiri ogwirira ntchito, omwe ndi ofunikira pamayadi akulu kapena mosungiramo zinthu. Kuphatikiza apo, utali wokwezeka wokwera umathandizira kuti crane iwunjike zotengera kapena kunyamula katundu wolemera pamalo okwera. Pamene kutalika ndi kutalika kumawonjezeka, momwemonso kuchuluka kwa zitsulo, zovuta za uinjiniya, ndi machitidwe owongolera omwe amafunikira, zomwe zimapangitsa kuti mtengo wa crane ukhale wokwanira.
♦ Zofunikira Zosintha Mwamakonda: Ntchito zambiri zimafunikira amphira matayala gantry cranezomwe zimapangidwira kuti zikwaniritse zofunikira zenizeni. Kusintha mwamakonda kungaphatikizepo zida zonyamulira zapadera, makina owongolera apamwamba, kapena zosintha kuti zigwirizane ndi masanjidwe achilendo pamalopo. Ngakhale kusintha makonda kumatha kukulitsa mtengo, kumatsimikizira kuti crane imalumikizana mosasunthika ndi kayendedwe ka ntchito, kumapangitsa kuti magwiridwe antchito azigwira bwino ntchito komanso zokolola. Crane yopangidwa mwaluso nthawi zambiri imabweretsa kubweza mwachangu pazachuma pochepetsa nthawi yotsika komanso kuchulukirachulukira.
♦Zinthu Zoyenda: Njira zowongolera zapamwamba ndi chinthu china chofunikira pamitengo. Mwachitsanzo, crane yokhala ndi chiwongolero cha mawilo anayi imapereka mphamvu zowongolera kwambiri poyerekeza ndi makina a mawilo awiri, zomwe zimalola oyendetsa kuti azigwira ntchito zovuta m'malo ochepa. Ma crane opaka matayala okhala ndi mawonekedwe olondola kwambiri ndi ofunika kwambiri m'malo omwe kuyika bwino kwa zotengera kapena zida ndikofunikira.
♦ Malo Ogwirira Ntchito: Malo omwe crane imagwirira ntchito imakhudzanso mtengo. Ma Crane omwe amagwira ntchito movutirapo, monga kutentha kwambiri, madera a m'mphepete mwa nyanja okhala ndi mchere wamchere, kapena malo okhala ndi zida zowononga, amafunikira njira zina zodzitetezera. Izi zingaphatikizepo zokutira zosagwirizana ndi dzimbiri, makina amagetsi otsekeredwa, kapena zida zowonjezera zama hydraulic, zomwe zimathandizira pamtengo wonse koma zimatsimikizira kudalirika komanso chitetezo kwanthawi yayitali.
♦ Kutumiza ndi Kuyika: Ndalama zoyendetsera ndi kukhazikitsa nthawi zambiri zimanyalanyazidwa koma zimatha kukhala zazikulu. Kukula kwa crane, kumapangitsa kuti ndalama zotumizira zimakwera komanso zovuta kwambiri pakuyika. Enaheavy duty gantry craneszimafuna thandizo lapadera lantchito kapena uinjiniya panthawi ya msonkhano, zomwe zimawonjezera ndalama zonse. Kukonzekera za mayendedwe ndi kukhazikitsa pasadakhale kungathandize kukweza mtengo komanso kuchepetsa kuchedwa kwa nthawi ya polojekiti.
Mwachidule, mtengo wa amphira matayala gantry craneimakhudzidwa ndi zinthu zingapo, kuphatikiza mphamvu yokweza, kutalika, kukweza kutalika, makonda, mawonekedwe oyenda, malo ogwirira ntchito, ndi zofunikira pakuyika. Kusankha crane yoyenera, monga 50 ton gantry crane kapena zosankha zina zolemetsa, zimatsimikizira kuti malo anu amatha kugwira ntchito motetezeka komanso moyenera ponyamula katundu wovuta. Kuyika ndalama mumtengo wapamwamba kwambiri wa gantry crane wogwirizana ndi zosowa zanu zogwirira ntchito sikumangowonjezera zokolola komanso kumapereka kudalirika kwanthawi yayitali, ndikupangitsa kuti ikhale yankho lanzeru komanso lotsika mtengo pantchito zamakono zama mafakitale.
