Marine Davit System
Imikhumbi ithwala Marine A-Frame Davits ukukhulisa izikebhe ezincane. Mayelana nokuhoxisa kanye nokwethulwa kwesikebhe, kunezinhlobo ezintathu zokuhlehlisa nokuqalisa: amandla adonsela phansi, ukushwiba, nokuphuma.
Ngokucacile, ukucaciswa kudinga ukuthi i-davit ikwazi ukubeka ngokushesha isikebhe esincane emanzini futhi isihlehlise phakathi, futhi ibe namandla uma itshekiswa ngamadigri angu-15 kunoma yiluphi uhlangothi futhi ngobude. Uma ijubane lingamafindo angu-5 futhi ukuthambekela kungu-5 degrees, isikebhe esincane singaphendulwa ngaphandle ngenkathi siphethe zonke izinto zokusebenza nabasebenzi ababili. Setha okungenani imigqa yokuphepha emibili ukuze uqinisekise ukuthi wonke amalungu ezisebenzi ahlale ngokuphephile ekhebulani le-cross-tension ye-surface davit. Ama-davit asolwandle afakwe izinto zokuphepha, njengokushintshwa komkhawulo, aklanywe ngendlela yokuthi lapho i-davit ifinyelela endaweni yayo yokucofa, amandla anqanyulwa ngokuzenzakalelayo.
Kungenzeka ukuhlukanisa uhlobo I-A-frame davit cranes zibe izinhlobo zikagesi nezehydraulic. Ukubuyisela izikebhe zokuhlenga (noma izikebhe zokuhlenga ngokushesha) olwandle olugubhayo, uhlobo lwe-hydraulic lunohlelo lwesinxephezelo samagagasi (isistimu ye-tension).
Ukwahlukaniswa kanye nomsebenzi wama-Marine Davit Cranes
Emikhumbini ehamba olwandle, ama-davit ahlukaniswa ngohlobo lwamandla adonsela phansi kanye nohlobo lwesigxobo esihlanekezelwe (uhlobo olujikelezayo alusasetshenziswa). Kunezinhlobo ezimbili zamadavithi adonsela phansi: ama-slide rails nama-tipping davits. Ngenxa yezikhundla zazo ezihlukene, lezi zinhlobo ezimbili zingahlukaniswa zibe izinhlobo ezihlukahlukene zesakhiwo. Amadavithi enduku ehlanekezelwe afika ngezinhlobo ezimbili: uhlobo lwenduku eqondile kanye nohlobo lwesikela. Lezi zinhlobo ezimbili nazo zingahlukaniswa zibe izinhlobo ezihlukahlukene zesakhiwo ngokusekelwe ekuhlelweni kwazo kanye nezidingo.
I-Gravity davits, evame ukusetshenziswa emikhunjini yasolwandle, ivula izikebhe ngokushesha futhi iphephile futhi inokwethenjelwa. I-davit ikhulula isikebhe ngaphansi kwamandla adonsela phansi lapho kuvulwa idivayisi yebhuleki. Ububi balesi simiso ukuthi izikebhe ezisindisa ukuphila zivame ukuphakanyiswa ku-davit, ephakamisa isikhungo somkhumbi samandla adonsela phansi.
Ama-davit e-pole-inverted-pole noma ama-swivel davit avamise ukuphakanyiswa aye endaweni ethile uma kwethulwa isikebhe. Ngenxa yalokhu, isikebhe siqala kancane futhi sithatha indawo yedekhi enkulu. Njengoba i-davit ibekwe ngqo emphemeni, isikhungo somkhumbi singehliswa. Ama-Davits anezigxobo ezihlanekezelwe ngokuvamile asetshenziswa ezikebheni zomfula ophakathi nezwe.
Ungakhetha kanjani i-crane ye-davit yasolwandle?
Ngaphezu kokubheka ukuhlelwa nokusebenza kwama-davits, ukukhethwa kwezinto ezisetshenziswayo zokusindisa impilo yemikhumbi yasolwandle kusekelwe kulokhu okulandelayo: imikhumbi yabagibeli, imikhumbi yokucubungula emanzini, imikhumbi yocwaningo lwesayensi kanye namathangi kawoyela ane-gross tonnage engamathani ayi-1600. nangaphezulu. Amadavithi ohlobo lwamandla adonsela phansi ayadingeka.
Amadavithi eminye imikhumbi: lapho isikebhe sokusindisa sinesisindo esingaphezu kwamathani angu-2.3 esimweni sokusebenza, uhlobo lwamandla adonsela phansi kufanele lwamukelwe; lapho isisindo singeqi amathani angu-2.3, kungasetshenziswa uhlobo lwesigxobo esihlanekezelwe noma uhlobo lwamandla adonsela phansi; uma isisindo singeqi ku-1.4 amathani, i-spiral ingasetshenziswa.
Marine A-Frame Davit Standard
- The Ama-davits we-A-frame zakhiwe futhi zenziwa ngokwezidingo ze I-SOLAS ezisetshenziswayo njengamanje.
- Ihambisana nezidingo zesinqumo i-MSC.47 (66) (isichibiyelo seNgqungquthela Yamazwe Ngamazwe Yokuphepha Kokuphila Olwandle ngo-1974) kanye nesinqumo se-MSC.48 (66) (Imithetho Yamazwe Ngamazwe Yezisetshenziswa Zokusindisa Ukuphila).
- Ngokwezidingo zokuhlolwa kwemishini esindisa impilo ye-MSC81 (70), zonke izisetshenziswa ziphumelele ukuhlolwa futhi zamukelwa.
Marine A-Frame Davit Izinhlobo
- Uhlobo lweHydraulic: I-NM30 (enomfutho oqhubekayo wemanuwali kanye nesistimu yokulwa nokushwibeka).
- Uhlobo lukagesi: NMAR30, NMAR30-1, NMAR60.
Isici se-Marine A-Frame Davit
- I-Gosea Marine Ama-davits e-A-frame anganikeza uchungechunge lwezinketho ngokuya ngezidingo zokusebenza.
- Izinto ezisetshenziswayo zamukela uhlaka oluqinile lwe-A, oluzinzile futhi oluphephile lapho lusebenza, futhi lucabangela ukugcinwa nokugcinwa kwesikhathi esizayo.
- Iwintshi ye-davit kanye nokunyakaza kwe-derrick kuqhutshwa ikhonsoli eseduze noma isilawuli kude.
- Ukuqala/ukumisa nesitobhi esiphuthumayo nakho kutholakala kukhonsoli noma isilawuli kude.
- Kungakhathaliseki ukuthi umkhumbi uhileleke emisebenzini yokuhlenga, imisebenzi yokuma, noma eminye imisebenzi ehlobene, ama-davit angahlonyiselwa ukwenza umsebenzi.
