Alamar Flat Top Tower Crane: Fayilatai da Iyakar Amana

Daidaiton Uwar Flat-Top Tower Cranes da Ma'anar Sasa

A cikin zamanen duniya mai yau, suna canzawa girgen gadoji a matsayin abubuwan amfani masu mahimmanci da suka kawo sabon yaukaka zuwa cikin ayyukan tarina ta hanyar tsari na iyakake, aiki mai toshewa, da iya iyakawa. Wadanda ke kama da lokuta masu hankali kamar tarina girma a kasuwanci ko ayyukan tarina mai yawa wanda yankuna da sauri a tarina suna da mahimmanci sosai, mahimmancin su ya fara fuskantar daidaita. Ba hanya ya daki kama da iyakun girgen gadoji na zamani a cikin alamom mai hankali ba, amma kuma yana ba da halayyen masira, masu taimako, da dadiyya ta hanyar ilmin tarina.

Daga cikin kama da yankin kasuwa masu karamin yau, tsari na flat-top tower crane (masin taguwa) yaɗa da sharuddan waje na madinai mai zaman kanso. Ta hanyar cire juyawa ta hagu da tsarin guy-rod a sama, tsarin ya sami nukarin flat. Wannan abubu daya yana ba da wasu alamar biyu: Na farko, yana ba da damar raba masu taguwa da hanya mai 3 mita kawai (wanda masu taguwa na musamman suna buƙata karshen 10 mita na kari), waɗanda suka ba da damar yin amfani da masu taguwa masu yawa don aiki masu taimakawa a wuraren masu daraja ko har garuruwa. Na biyu, yana cire abubuwan da ke taka muhimmancin halayen tushen tsari lokacin da masu taguwa masu yawa ke aiki ne a koma, yayin da yake inganta rashin tushen da rashin yanayin aikin masu taguwa. Wannan iko 'compact' na aiki ita ce zuciya mafi kyau ga kayan aikin gida mai girma da kayan aikin kasuwanci a madinai—wuraren da aikin yin gida ya kasance mai dadi akan garuruwa, kuma yin amfani da kowane inci na waje ya dace da takaitaccen aikin da kuma adadin biyan kuɗi.

Daga cikin iyaka da ayyukan amfani, kuma karfafa tafarki na flat-top tower cranes suna nuna alhali mai mahimmanci. Tsarin da aka kirkire shi (modular structural design) yana magana sosai kan ayyukan shigar da kawo: babu tsari mai matsala na musanya (tie-rod connection systems) wanda yana haɗawa da kayan dandamalin suttura da adadin ayyukan shigarwa. Wannan bai sa taƙaitaccen lokaci da ake buƙata don kowane shigarwa (masu fiye da 20%-30% ayyukan ajiya dibu duk da crane na gabaɗayan tafiyar) sai dai kuma yana kare zuwa ga kayan tafiya masu damuwa (misali, crane mai tafiyar suttura zasai iya kammala shigar da kayan dandi). Hakanan, gyara girman boom ba za a buƙatar kawowa komai ba. Gyara kayan dandamalin na basi zai iya canza girman aiki da waje, yayin da zai iya kauyata da kowane yanayin aikin taron gida—kamar tafiya mai kurum kurum a lokacin taron foundation zuwa tafiya mai girma a lokacin taron kayan gidajen gida. Wannan inganci bai sa kuduren biyan kayan aikin sai dai kuma yana iya kauyata da aikin taron gida, wanda ke kama da ayyukan taron gida mai girma da anaji.

Taimakon sauyi da kayan kanso suna nuna wani ikirin alhakin konkurensa na flat-top tower cranes. Tsarin sarari da kayan boom na rigido suna kara nema stress na kewaye a cikin boom a lokacin da aka samu loads a karkashin shekara. Wannan tsarin tie-rod na tower cranes na yawa suna ba da wasu madaidaici, amma suna yi abu ne zuwa ga cracks na fatigue bayan ma'aunin stress. Amma flat-top cranes suna canza tsarin bisa don raba stress akan takaitaccen tsari mai datsi, kuma yana bada abin da ya fara yawan shekaru na wasan kasa kuma yana kara nema frequency na maintenance. A hanyar gaba daya, rage gwargwado na farko yana kara nema abubuwan da zai haifar da cutar yayin da aka amfani da wasanne cranes a yankin karanci (lissafi yana nuna roughly 15% decrease a group operation accident rates). Yadda was suka hada da shi da kyauwar tacewa (typically maintaining stable operation in winds up to Force 6), wannan yana kara tabbatar da sauyin a lokacin da aka gina kan sama. Don gagayyaki mai yawa (kamar skyscrapers da yawa 300 meters) ko gargajiya mai yawa, wannan haɗin “high stability da low risk” ita ce abin da ake buƙata don tabbatar da ingancin gina.
