Kev tsim kom muaj crane khiav ua ke yog qhov tseem ceeb uas yuav tsum tau ntsib kev ua tau zoo thiab ua kom muaj kev nyab xeeb, ua haujlwm tau zoo. Cov neeg siv kawg yuav tsum ua kom ntseeg tau tias Crane thev tau nyob rau hauv cov lus qhia tshwj xeeb los ntawm Crane Manufacturers Association ntawm America (CMAA). Qhov tseem ceeb ua ntej saib xyuas nrog nce qib siab, spans, ncaj, thiab kev ua kom pom tseeb.
Vim li cas thiaj li muaj kev tso cai sau qoob loo kom zoo?
Aligned RUNway pab kom muaj kev nyab xeeb, ua haujlwm, thiab ua hauj lwm zoo rau koj cov haujlwm txav mus rau tom ntej. Kev sib zog tsis zoo tuaj yeem ua rau muaj kev ntxhov siab ntau dhau ntawm kev tso pa thiab lub tsev qauv qauv, ua rau crane racking, skewing, lossis khi. Hnav on crane Cheebtsam, xws li lub log thiab brakes, tuaj yeem muab ntxiv txoj hlab ntawm cov motors thiab lwm qhov system. Cov kab mob ncaj qha cuam tshuam rau lub neej ua haujlwm ncua thiab ua haujlwm tau zoo.
Koj tuaj yeem qhia tau li cas yog tias koj muaj kev ua haujlwm tsis zoo?
Koj yuav muaj kev sib txuas lus tsis zoo yog tias koj pom cov paib ceeb toom no:
Suab nrov, xws li tawg nrov nrov, thaum ua haujlwm
Nrib lub log flanges
Nce zog yuav tsum txav mus rau lub kaw lus crane los ntawm kev khiav
Kev tsheb ciav hlau txawv txav, log, lossis cov log coj tsis zoo
Cov log uas tshwm rau ntab lossis nce toj ntawm txoj kev tsheb nqaj hlau
Nws yog tau hais tias tus crane yuav khiav twj ywm thiab tsis qhia qee yam cim qhia tsis zoo. Vim tias misalignment tuaj yeem tsim ntau yam ntawm koj cov cuab yeej thiab tsev qauv tsim, hu rau hauv tus kws tshaj lij uas tuaj yeem txheeb xyuas cov teeb meem thiab ua tag nrho cov kev tiv thaiv tag nrho kev yees duab.
CAAA CRANE ROway Alignment Alignment
CMAA qhia qhov tshwj xeeb rau kev khiav. Thaum cov lus qhia no yog kev pab tswv yim thiab tsis tas yuav tsum tau ua, lawv tau txais thiab txhawb nqa kev ua tau ntev ntev. CMAA Specifications No. 70 thiab Tsis Tau. 70 Time Tsis Muaj. 70 thiab No. 70 Lub Xeev uas khiav yuav tsum yog ncaj, part, theem, thiab ntawm qhov nce ib. Cov xwm txheej no tseem ceeb rau kev ua kom zoo tshaj plaws crane ua tau nrog kev hnav me me. Lub ntsiab tseem ceeb cuam tshuam nrog cov plaub yam no muaj xws li:
Kev khiav yuav tsum tau ua raws li plaub yam rau (±) 1 \/ 4- nti hauv ib chav a.
Kev khiav yuav tsum tau ua raws li (±) 3 \/ 8- nti dhau ntawm qhov ntev puv ntoob ntev.

Kev tso cai khiav ceev
Kev tso mam li pawv yuav tsum tau nyob hauv kev ua taus los tiv thaiv kev ua ntej hnav thiab racking. Kev tso cai tso mam ua lwm yam tshwj xeeb muaj xws li:
Spans tsawg dua 50 ko taw tau tso cai rau 3 \/ 16- nti thev taus.
Spans 50 rau 100 ko taw tau tso cai rau ¼-inch thev taus.
Spans ntau dua 100 ko taw tau tso cai rau 3 \/ 8- nti thev taus.
Qhov yuav tsum tau ua rau muaj qhov siab tshaj plaws ntawm kev hloov ntawm ¼-nti rau txhua 20 feet ntawm kev khiav. Tshaj dhau cov kev tsim tawm no tuaj yeem ua rau muaj kev tawm tsam tsis zoo. Kev ua kom tsim nyog ua rau muaj kev sib txawv kom txo qis thiab txhawb kev ua haujlwm ntev.
Kev khiav nrawm
Kev khiav nrawm nce siab yuav tsum tsis pub dhau 3\/8 ntiv taw ntawm txhua txoj kev khiav. Rau cranes ncua tsawg dua 50 ko taw, kev tsheb ciav hlau yuav tsum tsis pub dhau 3\/16 ntiv. Rau cov cranes loj dua - Spanish 50 mus rau 100 ko taw - kev tsheb ciav hlau yuav tsum tsis pub dhau 1 \/ 4- nti. Ib qho 3 \/ {8- nti tsis kam lees rau cranes ncua ntau tshaj 100 ko taw. Zoo ib yam li CRANE CHANCATIONS, qhov siab tshaj ntawm kev hloov rau nce qib yog 1 \/ {19}} nti rau txhua 20 feet ntawm kev khiav.
Rawv Raighness
Yuav ua li cas ncaj koj txoj kev khiav yog nyob ntawm qhov chaw ntawm kev ntsia. CMAA cov qauv hais tias txhua lub tsheb ciav hlau tuaj yeem sib txawv 3\/8 ntiv tes ntawm nruab nrab. CMAA tswj cov kev qhia no txawm hais tias kev tsheb nqaj hlau loj.
Kab rov tav thiab ntsug ntshiab
CMAA thiab Kev Nyab Xeeb Kev Nyab Xeeb thiab Kev Noj Qab Haus Huv (OSHA) yuav tsum tau txav txhua yam khoom, xws li cranes thiab hoists, kom nyob ruaj khov ntawm tag nrho cov khoom nyob ruaj ruaj, xws li lub tsev qauv. OSHA qhia txog kev zam kev cuam tshuam los ntawm kev txhim kho cranes thiab hoists kom tshem tawm txhua yam kev sib tw ntawm kaum tsev, xws li ru tsev trusses, teeb, lossis kav dej, los ntawm 3 nti.
Dab tsi cuam tshuam rau kev siv khiav?
Ntau yam tuaj yeem ua rau cov kev khiav khiav kom dhau mus ua tsis ncaj ncees, suav nrog cov xwm txheej thiab hnub nyoog, thauj khoom xa tawm, thiab cov rog ib puag ncig.
1. Cov mob tag nrho
Koj lub taub dej crane yog lub hauv paus rau koj cov crane, yog li nws yuav tsum tau ua kom muaj kev ua tau zoo heev. Kev laus thiab corroded runways tuaj yeem cuam tshuam cov qauv sau qoob loo thiab ua rau hnav kom ua ntej hnav. Txheeb xyuas thiab daws cov teeb meem thiab cov teeb meem ntawm kev saib xyuas thiab kev tshuaj xyuas kom txuas ntxiv rau koj lub neej ua haujlwm ncua.
2. Load thauj khoom
Uneven lo faib rau ntawm Crane khiav tuaj yeem ua rau muaj kev tiv thaiv cov qauv uas ua rau tsis muaj cai. Yog hais tias tus crane xwm yeem nqa loads los ntawm tib qho chaw, cov nqaj yuav dhau thiab pib khoov lossis khoov lossis sag. Npaj cov khoom thauj khoom thiab tig crane cov chaw tuaj yeem pab txhim kho kev faib khoom thiab txo qis hnav thiab tsis zoo.
3. Lub Tsev Hais Haum
Raws li lub tsev lub hauv paus pib teeb tsa vim av cog lus lossis cov dej noo cov ntsiab lus hloov pauv sab hauv thiab ua rau kev khiav tawm kom ua tsis raug cai. Yog tias cov Cheebtsam Foundation sib haum xeeb ntawm cov nqi sib txawv, nws yuav muab kev txhawb nqa tsis sib xws rau Crane khiav, ua rau khoov, ua txhaum cai, lossis kev thauj khoom tsis sib luag. Kev tshuaj xyuas ib txwm tuaj yeem qhia tau ua kom muaj kev sib luag thiab cov hauv kev rau qib thiab cov tshuab ntse.
4. Ib puag ncig yam
Crane khiav kev sib tw tuaj yeem hloov pauv nyob ntawm ib puag ncig ib puag ncig xws li:
Kev hloov pauv hloov pauv uas ua rau cov hlau los nthuav dav thiab sib cog lus.
Nce dej noo noo uas tuaj yeem ua cov av thiab nrawm tsis muaj kev sib luag.
Seismic ua uas cuam tshuam cov qauv kev ruaj ntseg.
Kev ua haujlwm ntawm cov haujlwm nyob ze, tshuab, lossis kev siv uas maj mam misalign runways.
Kev pheej hmoo txaus ntshai los ntawm kev kawm txog ib puag ncig uas koj lub crane ua haujlwm. Ua kev tshuaj xyuas thiab cov txheej txheem tu kom paub meej cov qauv kev ruaj khov thiab kev nyab xeeb.
Dab tsi yog Crane Rail Tripment Tripment entail?
Daim ntawv ntsuam xyuas ib txog kev ua haujlwm txhawb nqa txoj kev khiav kom zoo los txo kev puas tsuaj thiab txuas ntxiv cov cuab yeej siv sia. Ntau yam tuaj yeem tso cov txheej txheej khiav, yog li nws yog lub tswv yim zoo saib rau cov suab tsis txawv lossis cov cim ntawm racking. Ua kev soj ntsuam pom zoo ib txwm muaj thiab tsim cov sijhawm rau kev saib xyuas ib ntus thiab kev txij nkawm txhua xyoo kom ntseeg tau tias koj qhov kev tso tawm hauv txoj kev nyob zoo. Tshawb xyuas koj cov kev tso tawm cov pawv tom qab muaj kev puas tsuaj tseem ceeb, xws li kev puas tsuaj ntuj lossis kev hloov pauv kub heev, mus ntes cov teeb meem kub thaum ntxov.
Hu rau tus neeg soj ntsuam muaj txiaj ntsig uas tuaj yeem ua cov kev sojntsuam raws cai thiab tshawb xyuas txhua qhov tsis sib xws. Cov kws tshaj lij no tuaj yeem siv cov cuab yeej siv roj, xws li cov khoom siv laser, ua kom pom kev sai thiab raug. Cov kws tshaj lij tuaj yeem kuaj thiab kho koj cov kev khiav tawm sai thiab yooj yim, ua kom koj cov crane ua haujlwm tsawg.
