Pawirigirder pamwambacraneskukhala ndi mphamvu zonyamulira zabwino komanso kapangidwe kake ka geometric, komwe kumatsimikizira kugwira ntchito bwino ndikuchepetsa kuvala. Popeza mbedza imatha kukwera pakati pa mizati iwiri ikuluikulu, kutalika kokweza kumawonjezeka kwambiri. Monga njira, nsanja yokonza ndi nsanja ya trolley imatha kukhazikitsidwa, yomwe sikuti imangothandizira kukonza crane, komanso imathandizira ogwira ntchito yosamalira kuti afikire mwachangu komanso mosamala malo ena mufakitale, monga zida zowunikira, kutentha kapena mapaipi amagetsi. .
Zigawo zapawiri girderbridge craneziyenera kufufuzidwa nthawi zonse, ndipo mavuto obisika ayenera kulembedwa mwatsatanetsatane kuti apewe ngozi.
Kuvala kosagwirizana kwa pulley groove kungayambitse kusagwirizana kosagwirizana pakati pa chingwe cha waya ndi pulley, ndipo pazovuta kwambiri, ngozi zogwirira ntchito zidzachitika; kuvala kwambiri kwa shaft ya pulley kungapangitse kuti shaft ya pulley ithyoke mosavuta. Chovalacho chikaposa malamulo oyenerera, chiyenera kusinthidwa.
Ngati gawo loopsa pa mbedzachadouble mtengo eot cranekutsegula kumavala kupitirira muyezo kapenamchiraulusi poyambira, ndi mbedza pamwamba ndi kutopa ming'alu, n'zosavuta chifukwa mbedza kusweka. Chifukwa chake, mbedza iyenera kuyang'aniridwa 1 mpaka 3 pachaka ndikusinthidwa munthawi yake ngati vuto likupezeka.
Ngati ma spokes ndi mapondedwe apawiri girder pamwambacranegudumu limakhala ndi ming'alu ya kutopa, kapena gudumu la gudumu ndi kupondaponda kumapitilira muyezo, ndikosavuta kupangitsa kuti gudumu liwonongeke, ndipo pakavuta kwambiri, crane imasokonekera.
Kutentha, phokoso ndi lubrication wa mayendedwe a mbali iliyonse yakawiri mtengo etcraneziyenera kufufuzidwa nthawi zonse; ngati chochepetsera chikumveka chachilendo, chiyenera kukonzedwa kapena kusinthidwa panthawi yake.
Ngati njira yopatsirana imapatuka kwambiri, chimango chimasokonekera ndikupunduka, zolakwika za njanji ndi magudumu zimakhala zazikulu kwambiri, kapena pali mafuta panjanjiyo, zipangitsa kuti galimotoyo idye polowera pogwira ntchito, ndipo iyenera kukhala kusinthidwa, kutsukidwa, ndi kukonzedwa munthawi yake.
Pazosowa zapadera zamafakitale, timapereka mayankho okhazikika. Kaya ndi kutentha kwambiri, chinyezi chambiri, malo owononga kapena malo apadera ogwirira ntchito,pawiri girder mlathocranesakhoza kupereka ntchito zabwino kwambiri.
