Hauv kev ua haujlwm fais fab thiab kev saib xyuas thiab kev saib xyuas cov chaw ua haujlwm, cov ntaiv tsis yog tsuas yog tus nqa khoom rau kev ua haujlwm siab -qhov siab, tab sis kuj yog txoj kab tseem ceeb tiv thaiv kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm lub neej. Txawm li cas los xij, cov ntaiv tsis tsim nyog feem ntau hu ua "lub neej-txuag ntaiv", thiab cov hluav taws xob poob siab thiab siab - qhov siab poob los ntawm lawv tsis tshua muaj tshwm sim hauv kev lag luam. Piv txwv li, tus neeg teb xov tooj yuam kev siv cov txheej txheem aluminium alloy ntaiv ua lub neej ua haujlwm platform, ua rau tam sim no dhau los ntawm tib neeg lub cev thiab tsim ib lub voj voog; Los yog cov khoom siv ntawm tus ntaiv yuav plam nws cov khoom siv rwb thaiv tsev vim tias ya raws thiab kev laus, ua rau muaj kev puas tsuaj loj hauv qhov chaw ntub dej thiab ntub dej.
Txhawm rau zam qhov xwm txheej zoo li no, kev xaiv cov txheej txheem rwb thaiv tsev yuav tsum tsis txhob ua raws li kev paub dhau los, tab sis yuav tsum ua raws li cov txheej txheem nruj. Peb cov txheej txheem hauv qab no yuav pab koj txheeb xyuas thiab xaiv cov txheej txheem rwb thaiv tsev ua raws.
Thawj qhov kev ntsuas: Kev ua raws li cov khoom siv thiab cov qauv ntawv pov thawj
Tus nqi tseem ceeb ntawm tus ntaiv insulated yog nyob rau hauv nws lub peev xwm los thaiv tam sim no, uas nyob ntawm tag nrho cov khoom thiab cov txheej txheem tsim khoom.
Cov khoom siv fiberglass nyiam: Nws yog nruj me ntsis txwv tsis pub siv hlau (aluminium alloy / steel) ntaiv hauv kev ua haujlwm hluav taws xob. Raws li kev rwb thaiv tsev ladders yuav tsum tau ua los ntawm fiberglass reinforced yas. Cov khoom no muaj zoo heev dielectric zog thiab txhua yam muaj zog. Thaum ua kev yuav khoom, nws yog ib qho tsim nyog kom paub meej tias cov khoom siv fiber ntau yog qhov sib xws, tsis muaj npuas, wrinkles, los yog cov khoom siv fiber ntau, vim tias txhua qhov tsis xws luag yuav dhau los ua cov ntsiab lus tsis muaj zog rau rwb thaiv tsev tawg. Tshawb xyuas lub teb chaws cov qauv (GB Standards): Nyob rau hauv Suav lag luam, tsim nyog insulated ladders yuav tsum ua raws li GB/T 17620-2008 "Insulated Hard Ladders for Live Working". Thaum yuav khoom, cov neeg muag khoom yuav tsum tau muab cov ntaub ntawv ntsuam xyuas hom thiab daim ntawv pov thawj kev kuaj xyuas lub Hoobkas uas muab los ntawm cov chaw kuaj kev tso cai. Qhov no yog tib txoj cai lij choj los xyuas seb tus ntaiv puas muaj qhov nominal rwb thaiv tsev
Raws li.
Qhov ntsuas thib ob: qib hluav taws xob thiab ib puag ncig kev sib raug zoo
Kev xaiv cov txheej txheem rwb thaiv tsev yuav tsum ua raws li lub hauv paus ntsiab lus ntawm "kev ntsuas hluav taws xob ua ntej ua haujlwm", uas txhais tau hais tias kev sib raug zoo raws li qhov ntsuas hluav taws xob thiab ib puag ncig ntawm qhov chaw ua haujlwm.
Clear voltage kam rau ua theem: Lub peev xwm ntawm lub rwb thaiv tsev ntaiv muaj qhov tseeb voltage txwv. Piv txwv li, cov qauv laminated thiab thickness ntawm tus ntaiv siv rau ib puag ncig hauv qab 1kV yog txawv kiag li ntawm cov siv rau ib puag ncig ntawm 10kV thiab 35kV. Thaum xaiv, qhov ntsuas hluav taws xob ntawm tus ntaiv yuav tsum siab dua qhov system voltage ntawm qhov chaw ua haujlwm, thiab cov npoo txaus yuav tsum tau khaws cia.
Xav txog kev cuam tshuam ntawm ib puag ncig cov av noo: Hauv cov av noo ib puag ncig xws li cov yeeb nkab hauv av thiab lub caij ntuj no sab nraum zoov, cov dej molecules yuav tsim cov yeeb yaj kiab dej ntawm tus ntaiv, txo qhov kev tiv thaiv nto. Hauv cov xwm txheej zoo li no, cov ntaiv tshwj xeeb rwb thaiv tsev uas tau dhau los ntawm kev ya raws- pov thawj kev kho mob lossis muaj cov txheej txheem hydrophobic tshwj xeeb yuav tsum raug xaiv, thiab cov txheej txheem rwb thaiv tsev yuav tsum tsis txhob siv rau hauv qhov chaw ntub dej.
Thib peb cov txheej txheem: Cov qauv kev ruaj ntseg thiab lub zog txhua yam
Ntxiv rau qhov kev ua tau zoo ntawm hluav taws xob, cov khoom siv tshuab ntawm tus ntaiv yog ncaj qha ntsig txog kev tiv thaiv kev poob.
Locking mechanism thiab kev txhawb nqa: Xyuas seb qhov kev xa khoom xauv lub tshuab ntawm tus ntaiv puas ruaj khov thiab txhim khu kev qha. Rau ib tug zigzag ntaiv, yuav tsum tau them nyiaj mloog mus rau lub zog ntawm nws sab ncej txhawb nqa; Rau telescopic ladders, nws yog ib qho tsim nyog yuav tsum tau xyuas seb qhov ntsuas qhov ntsuas puas yog qhov tseeb. Txhua qhov kev co ntawm cov qauv yog qhov muaj feem xyuam rau kev nyab xeeb.
Kev tiv thaiv plam tsim thiab thauj khoom- qib bearing: Qhov saum npoo ntawm lub pedal yuav tsum muaj kev ntxhib los mos los yog npog nrog cov roj hmab los tiv thaiv. Cov ntaiv taw yuav tsum tau nruab nrog cov khoom siv roj hmab ruaj ruaj kom tiv thaiv kom tsis txhob ntog thiab muab cov rwb thaiv tsev hauv qab. Nyob rau tib lub sijhawm, cov ntaiv uas muaj qhov ntsuas txaus txaus (feem ntau yog qib kev lag luam xav tau ntau dua lossis sib npaug ntawm 150kg) yuav tsum raug xaiv raws li qhov hnyav ntawm cov neeg ua haujlwm thiab tag nrho qhov hnyav ntawm cov cuab yeej nqa, thiab kev thauj khoom hnyav yog txwv nruj.
Hauv kev ua haujlwm fais fab, kev nyab xeeb yog txoj kab liab uas tsis tuaj yeem tawg. Ib tug qis- ntaiv zoo yuav txuag tau tus nqi yuav khoom, tab sis nws yuav ua rau tus nqi ntawm lub neej tsis zoo. Kuv vam tias txhua tus kws tshaj lij thiab cov neeg txiav txim siab yuav khoom tuaj yeem ua raws li cov lus qhia saum toj no thiab ua raws li qhov tseem ceeb. Tshem tawm "tus ntaiv tuag" los ntawm txhua qhov kev xaiv nruj.
