Nyob rau hauv xyoo tas los no, nrog kev nce ntawm kev lag luam logistics, roj hmab tyred gantry cranes (RTG) tau dhau los ua neeg nyiam. Kuv tsis paub yog tias koj paub txog cov log tsheb hom cranes. Lub log tsheb hom crane yog qhov feem ntau hu ua lub log tsheb crane, uas siv lub log tsheb chassis txav lub boom thiab tig nws. Crane, vim qee tus neeg tau tshaj tawm tias lawv tsis paub yuav xaiv cov cuab yeej no li cas, yog li hnub no kuv yuav tham txog cov ntsiab lus xaiv ntawm cov log tsheb hom cranes. Cov tseem ceeb yog raws li nram no:
1. Ib leeg thiab ob kab teeb
Raws li ib txwm muaj, yog tias lub peev xwm nqa tsawg dua 50t, qhov ntev yog nyob rau hauv 35m, thiab tsis muaj qhov tshwj xeeb yuav tsum tau siv, ib leeg-girder roj hmab tyred thawv crane yuav tsum raug xaiv. Yog tias koj xav tau lub qhov rooj loj dav dav, kev ua haujlwm siab, lossis yog tias koj feem ntau nqa cov khoom hnyav lossis ntev, koj yuav tsum xaiv lub log tsheb ob-girder-hom crane.
2. ncua
Qhov ntev ntawm lub log tsheb-hom crane yog qhov tseem ceeb cuam tshuam rau qhov zoo ntawm crane nws tus kheej. Thaum xaiv, qhov ncua sij hawm yuav tsum raug txo kom tsawg li ntau tau ntawm qhov chaw ua tau raws li cov khoom siv thiab ua raws li cov qauv span series.
3. Kev txiav txim siab ntawm wheelbase
(a) tuaj yeem ua tau raws li qhov yuav tsum tau muaj kev ruaj ntseg ntawm lub mast raws li kev taw qhia ntawm crane khiav
(b) Tag nrho qhov ntev ntawm cov khoom thauj yuav tsum muaj peev xwm dhau los ntawm lub tiaj tus steel ncej ntawm cov outriggers smoothly
(c) Ua tib zoo ua kom lub log puag B thiab ncua S muaj qee qhov kev sib raug zoo. Feem ntau, lub log puag B=(1/4-1/6) S.
4. Qhov luaj li cas
Thaum lub sijhawm ua haujlwm, qee qhov chaw yuav tsum tau sab laug ntawm qhov ntev ntawm RTG lub thawv crane thiab cov khoom thauj thiab thauj cov tsheb thauj mus los hauv lub vaj kom yooj yim thauj khoom thiab thauj khoom. Thaum thauj thiab tshem tawm cov tsheb thauj khoom dav dav nyob rau hauv qhov ncua sij hawm, lawv yuav tsum nyob deb ntawm ntau tshaj {{0}}.7m ntawm lub qhov rooj ob txhais ceg. Thaum lub tshuab kis tsis ua haujlwm, yuav tsum muaj qhov nrug deb tshaj li 0.5m ntawm lub tsheb thauj khoom. Thaum cov khoom dhau los ntawm lub qhov rooj ob txhais ceg, yuav tsum muaj kev ncua deb ntawm ntau tshaj 0.5m.
