Kreni yokwera pamwamba yokhazikika yokhala ndi mipiringidzo iwiri yokhala ndi trolley

Crane Yokhala ndi Magiya Awiri Oyimirira ndi makina odabwitsa omwe asintha mafakitale. Yopangidwa kuti inyamule katundu wolemera mosavuta komanso molondola, crane iyi imapereka magwiridwe antchito komanso chitetezo chosayerekezeka pakusamalira zinthu. Ndi kapangidwe kake kolimba komanso mawonekedwe apamwamba, ma crane oyenda pamwamba a giya awiri amaonekera bwino kwambiri ndipo ndi chisankho choyamba m'mafakitale ambiri.
Chimodzi mwa ubwino wapadera wa ma crane oyenda pamwamba pa double girder ndi mphamvu yawo yonyamula katundu kwambiri. Ma brane awiri a crane ali m'mbali mwa mlatho, zomwe zimapangitsa kuti ikhale yolimba komanso yolimba. Imatha kunyamula katundu wolemera kuyambira matani ochepa mpaka matani mazana angapo, zomwe zimapangitsa kuti ikhale yoyenera mafakitale omwe amagwiritsa ntchito zipangizo zazikulu komanso zazikulu. Kaya ndi opanga, zomangamanga kapena zoyendera, crane iyi ili ndi mphamvu komanso kuthekera kogwira ntchito zofunikira kwambiri pakugwiritsa ntchito zipangizo.
Kuwonjezera pa mphamvu zodabwitsa zonyamula katundu, ma crane oyenda pamwamba pa double girder amaperekanso ntchito zosiyanasiyana. Popeza ali ndi njira zosiyanasiyana zokwezera ndi njira zowongolera, crane imapereka njira zonyamulira ndi kunyamula zolondola komanso zogwira mtima. Ndi zida zake zapamwamba zodziyimira pawokha, ogwiritsa ntchito amatha kuwongolera mosavuta ndikuyang'anira mayendedwe a crane, kuonetsetsa kuti ntchito zogwirira ntchito sizimasokonekera. Kuphatikiza apo, ma crane oyenda pamwamba pa double girder amatha kupititsa patsogolo magwiridwe antchito awo komanso kusinthasintha kwawo mwa kuphatikiza zida zothandizira monga zogwirira, maginito kapena mipiringidzo yonyamulira kuti igwirizane ndi zofunikira zamakampani.
Chitetezo ndiye nkhani yofunika kwambiri m'mafakitale aliwonse ndipo ma crane ozungulira okhala ndi ma girder awiri ndi abwino kwambiri pankhaniyi. Adapangidwa ndi zinthu zachitetezo zomwe zimapangidwa mkati mwake kuphatikizapo njira yotetezera kupitirira muyeso, batani loyimitsa mwadzidzidzi komanso mabuleki osalephera kuti atsimikizire kuti ogwira ntchito ndi antchito ali bwino. Kapangidwe kake kolimba komanso zipangizo zapamwamba zimathandizira kuti ntchito ikhale yogwira ntchito kwa nthawi yayitali komanso kuchepetsa ndalama zokonzera ndi kukonza pakapita nthawi. Kuphatikiza apo, ma crane oyendayenda okhala ndi ma girder awiri amatha kukhala ndi njira zowunikira komanso zodziwira mavuto omwe angakhalepo, zomwe zimathandiza kukonza mwachangu komanso kuchepetsa nthawi yogwira ntchito.
