Kev txhim kho keeb kwm ntawm portal scaffold

Portal scaffold yog ib qho ntawm feem ntau siv scaffolds hauv kev tsim kho. Vim hais tias lub ntsiab ncej yog nyob rau hauv cov duab ntawm "qhov rooj", nws yog hu ua portal los yog portal scaffold, kuj hu ua Eagle thav duab los yog gantry. Hom scaffold no yog tsim los ntawm lub ntsiab ncej, ntoo khaub lig ncej, hla kab pheeb ces kaum brace, scaffold board, adjustable puag, thiab lwm yam.

Portal scaffold yog ib qho ntawm feem ntau siv scaffolds hauv kev tsim kho. Vim hais tias lub ntsiab ncej yog nyob rau hauv cov duab ntawm "qhov rooj", nws yog hu ua portal los yog portal scaffold, kuj hu ua Eagle thav duab los yog gantry. Hom scaffold no yog tsim los ntawm lub ntsiab ncej, ntoo khaub lig ncej, hla kab pheeb ces kaum brace, scaffold board, adjustable puag, thiab lwm yam. Portal scaffold yog ib qho cuab yeej tsim ua ntej tsim los ntawm Tebchaws Meskas thaum xyoo 1950s. Vim tias nws muaj qhov zoo ntawm kev sib dhos yooj yim thiab disassembly, yooj yim txav, muaj peev xwm zoo, siv kev nyab xeeb thiab txhim khu kev qha thiab cov txiaj ntsig zoo nyiaj txiag, nws tau tsim sai heev. Los ntawm xyoo 1960, Tebchaws Europe, Nyiv thiab lwm lub tebchaws tau ua tiav thiab tsim cov khoom siv zoo li no. Hauv Tebchaws Europe, Nyij Pooj thiab lwm lub tebchaws, kev siv portal scaffold yog qhov loj tshaj plaws, suav txog li 50% ntawm txhua yam ntawm scaffolds, thiab ntau lub tuam txhab kev lag luam uas tsim portal scaffolds ntawm ntau lub tshuab tau tsim nyob rau hauv ntau lub teb chaws.

Txij li thaum xyoo 1970, Tuam Tshoj tau ua tiav qhov kev nthuav qhia portal scaffold system los ntawm Nyiv, Tebchaws Meskas, Tebchaws Askiv thiab lwm lub tebchaws, uas tau siv rau hauv kev tsim kho ntawm qee lub tsev siab thiab ua tiav cov txiaj ntsig zoo. Nws tuaj yeem siv tsis tau tsuas yog sab hauv thiab sab nraud scaffolds rau kev tsim vaj tsev, tab sis kuj ua rau hauv pem teb slab, beam formwork txhawb nqa thiab txawb scaffold. Nws muaj ntau lub zog, yog li nws tseem hu ua multi-functional scaffold.

Los ntawm thaum ntxov 1980s, ib co domestic thiab manufacturers pib xyaum ua portal scaffold. Txog xyoo 1985, 10 portal scaffold manufacturers tau tsim ua tiav. Lub portal scaffold tau nrov nrov thiab siv rau hauv kev tsim kho cov haujlwm hauv qee qhov chaw, thiab tau txais tos los ntawm cov tsev tsim kho ntawm Guangda. Txawm li cas los xij, vim muaj cov khoom sib txawv thiab cov qauv zoo ntawm txhua lub Hoobkas, nws coj qee qhov teeb meem rau kev siv thiab kev tswj hwm ntawm chav tsev tsim kho. Qhov no tau cuam tshuam rau kev txhawb nqa ntawm cov cuab yeej tshiab no.

Los ntawm xyoo 1990, hom scaffold no tsis tau tsim thiab siv tsawg dua hauv kev tsim kho. Ntau lub gantry scaffold factories raug kaw los yog hloov mus rau ntau lawm, thiab tsuas yog ob peb chav nyob nrog kev ua haujlwm zoo txuas ntxiv mus tsim. Yog li ntawd, nws yog ib qho tsim nyog los tsim ib hom tshiab portal tripod ua ke nrog cov yam ntxwv ntawm peb lub teb chaws.
