50 Tuj Ob Chav Girder Cantilever Gantry Crane nrog Log

Ob chav girder cantilever gantry crane nrog lub log muaj lub qhov rooj ncej, lub zog xa hluav taws xob, lub tshuab nqa, lub laub khiav mechanism thiab lub log tsheb khiav. Lub log tuaj yeem ua rau lub crane taug kev ywj pheej yam tsis tau tso txoj kev khiav, thiab tseem tuaj yeem tig, yog li kev ua haujlwm hloov tau yooj yim thiab siv tau yooj yim. Nws tuaj yeem nqa mus txog 50 tons ntawm cov khoom ib zaug, tab sis vim yog lub cantilever ntawm ob qho kawg, qhov kev ncua deb ntawm kev thauj khoom yog ntev dua. Thiab nws txo qis kev tuav haujlwm ntawm cov neeg ua haujlwm thiab txuag sijhawm rau kev thauj khoom thauj.

Lub caij no, hom gantry cranes tsim los ntawm peb lub tuam txhab tuaj yeem muab faib ua pawg hauv qab no:
① Ordinary gantry crane: Hom crane no yog siv dav tshaj plaws, thiab tuaj yeem ua ntau yam khoom thiab cov ntaub ntawv loj, nrog lub peev xwm nqa tsawg dua 100 tons thiab qhov ntev ntawm 4 txog 35 meters. Feem ntau, zoo tib yam gantry cranes nruab nrog lub thoob elevator muaj qib ua haujlwm siab dua.

②Gantry cranes rau cov chaw nres tsheb hydropower: feem ntau yog siv los nqa thiab qhib thiab kaw lub qhov rooj, thiab tuaj yeem siv rau kev teeb tsa. Lub peev xwm nqa tau yog 80-500 tons, qhov dav me me, 8-16 meters; lifting ceev yog tsawg, 1-5 meters ib feeb. Hom crane no siv tsawg dua rau kev nqa, tab sis thaum nws siv los nqa, nws yuav tsum tau nce qib ua haujlwm kom tsim nyog.

③Shipbuilding gantry crane: Nws yog siv los sib sau ua ke ntawm lub berth. Ib txwm muaj ob lub lifting trolleys: ib tug muaj ob lub ntsiab hooks thiab khiav ntawm txoj kev ntawm lub sab sauv flange ntawm tus choj; lwm tus muaj lub ntsiab nuv thiab ib tug pab nuv. Nws khiav ntawm kev khiav ntawm qhov qis flange ntawm tus choj ncej kom tig mus thiab hoist loj hull ntu. Lub peev xwm nqa tau feem ntau yog 100-1500 tons; qhov ntev yog mus txog 185 meters; lifting ceev yog 2-15 meters ib feeb.

④Container gantry crane: siv nyob rau hauv lub thawv terminals. Tom qab cov tsheb thauj khoom thauj cov thawv ntim khoom thauj khoom los ntawm lub nkoj los ntawm quay phab ntsa thawv thauj khoom choj mus rau lub vaj lossis tom qab, lawv tau muab tso rau ntawm lub thawv gantry crane lossis ncaj qha thauj khoom thiab thauj mus los, uas tuaj yeem ua kom nrawm nrawm ntawm lub thawv thauj khoom thauj khoom lossis lwm yam cranes. Lub thawv me me uas tuaj yeem ntim 3 mus rau 4 txheej siab thiab 6 kab dav feem ntau yog siv rau hauv hom log tsheb, thiab tseem muaj txiaj ntsig zoo hauv kev tsheb ciav hlau. Qhov nqa ceev yog 35-52 meters ib feeb, thiab qhov ncua sij hawm yog txiav txim siab los ntawm cov kab ntawm cov thawv uas yuav tsum tau ncua, nrog rau qhov siab tshaj plaws ntawm 60 meters.
