Kuwunika kogwira ntchito kumachitika tsiku ndi tsiku ndisingle girder pamwamba cranewoyendetsa. Nthawi zoyendera zimadalira kukhudzidwa kwa gawolo komanso kuchuluka kwa kung'ambika.
Nthawi zowunikira zimadalira kukhudzidwa kwa gawolo, kuchuluka kwa kuwonongeka, kulephera kapena kuwonongeka. Katswiri woyenelera woyenerera atha kuthandizira kudziwa nthawi yoyendera kutengera gawo, kayendedwe kantchito ndi malingaliro opanga.
Chinthu chachikulu pakuzindikira mtengo wa asingle girder pamwamba cranekuwunika ndi kuchuluka kapena mtundu wa kuwunika kwa crane komwe kumachitika. Kudziwa momwe kuyendera kumafunika nthawi zambiri ndiye gawo loyamba lodziwira zomwe zimayendera komanso pafupipafupi. Kukhala ndi dongosolo loyendera lomwe limakwaniritsa zofunikira za OSHA, ASME ndi CMAA kudzakuthandizani kutsatira malamulo oyendera.
Kodi kupanga kuyenera kuyimitsidwa panthawi yoyendera?
Yankho losavuta ndilo: osati kwenikweni.
Ngati muli ndimafakitale apamwamba cranekukonza mzere wopangira, ndiye kuti mzerewo udzakhudzidwa chifukwa kuyenderako kumatha kwa maola angapo. Komabe, ngati muli ndi ma cranes angapo pamtunda wosiyanasiyana, ndiye kuti malo ena onse amatha kupitiliza kugwira ntchito.
Ngati pali ma crane angapo okwera pamafakitale panjira yomweyi ndipo woyang'anira amatha kudzipatula kuti awonedwe, ndiye kuti crane ina imatha kuthamanga kuti ipititse patsogolo kupanga. Kuchita izi kudzafunika kuti woyang'anira achitepo kanthu kuti adziteteze ku crane ina yomwe ikugwirabe ntchito panjanjiyo.
Kodi acrane pamwamba pa monorailakuyenera kukhala pansi kuti awonedwe?
Pali zosintha zosiyanasiyana zomwe zimatsimikizira kuti zidzatenga nthawi yayitali bwanji kuti kuyendera.
Zimatengera zovuta zacrane pamwamba pa monorail. Chingwe chapamwamba chokhala ndi girder chapamwamba chokhala ndi mphamvu yokwana matani 1-20 chitenga nthawi yocheperako kuti chiwunikidwe kuposa chiwombankhanga chapamutu chapawiri. Chotsatira chachikulu cha nthawi yopuma ndi chiwerengero cha zigawo zomwe zimayenera kuyang'aniridwa.
