Gantry crane yog ib qho tseem ceeb lifting machinery nyob rau hauv txoj kev thiab choj engineering. Nws lub npe los ntawm qhov tseeb tias cov qauv ntawm cov khoom siv zoo li lub qhov rooj loj, yog li nws hu ua "gantry crane". Txawm li cas los xij, nyob ntawm thaj tsam thiab kev loj hlob ntawm lub sijhawm, nws yog hu ua beam lifting tshuab, gantry crane, gantry crane, gantry crane, thiab lwm yam. Yog li cov khoom siv tshwj xeeb zoo li cas?
Beam lifting tshuab: Lub beam lifting tshuab siv nyob rau hauv lub sij hawm ib txwm muaj nyob rau hauv prefabricated beam yards. Lub luag haujlwm tseem ceeb ntawm lub tshuab nqa beam hauv prefabricated beam yard yog nqa kab teeb. Lub beam pieces nyob rau hauv lub beam yard muaj xws li T beams, thawv beams, phaj beams, thiab lwm yam. Li no lub npe - beam lifting tshuab. Lub beam lifting tshuab yog tshwj xeeb yog siv rau lifting prefabricated beams. Nws tuaj yeem nqa tau ib leeg lossis ua khub. Nws txoj kev taug kev tseem ceeb yog nteg lem rau hauv av. Feem ntau, ntau yam haujlwm zoo sib xws yuav raug teeb tsa rau ntawm txoj kev taug tib lub sijhawm. Lub paj khib qauv yog ntau dua. Lub ntsiab yog vim li cas lub sij hawm tsim kho yog luv luv, tus nqi qis, tus nqi demolition yog tsawg, thiab tus nqi ntawm tag nrho qhov project tau txais kev cawmdim.
Gantry crane: Lub npe ntawm gantry crane yog nrov dua, xa mus rau gantry crane, uas sawv hauv av zoo li lub qhov rooj thiab ob txhais ceg. Vim nws qhov loj me, nws yog lub npe hu ua gantry crane. Gantry cranes feem ntau yog hom truss thiab lub thawv hom. Lawv yog siv rau kev tsim nkoj loj. Qhov kev ncua yog feem ntau loj. Lub ntsiab nqaj loj feem ntau yog nyob nruab nrab ntawm 10-30 meters thiab qhov siab nqa yog 6-15 meters. Txhua qib A3-A8 tuaj yeem muab tau.
3. Portal crane: Lub npe scientific ntawm gantry crane yog portal crane, uas kuj yog hom crane. Hom crane no tsuas yog siv rau kev thauj khoom thiab thauj khoom ntawm cov chaw nres nkoj, tab sis cov khoom thauj dav dav gantry crane thiab chaw nres nkoj gantry crane yog hom no. Lub npe tag nrho yog cargo yard gantry crane, hu ua cargo yard gantry crane, li no lub npe - gantry crane.
