1. Tshawb xyuas cov haujlwm ua ntej siv
a. Yuav tsum tsis muaj kev cuam tshuam thiab cov khoom ntab hauv qhov kev taug kev ntawm tus neeg teb xov tooj, nyob rau hauv txoj kab ntawm qhov pom, thiab ntawm txoj kev uas cov khoom hnyav dhau mus.
b. Txoj kev nce thiab nqis, sab laug thiab txoj cai ntawm phau ntawv tswj khawm yuav tsum yog thiab rhiab, thiab lub cev muaj zog thiab reducer yuav tsum tsis muaj suab txawv txav.
c. Lub nres yuav tsum tau rhiab heev thiab txhim khu kev qha.
d. Yuav tsum tsis muaj teeb meem txawv teb chaws ntawm txoj kev khiav ntawm hluav taws xob hoist.
e. Qhov kev txiav txim ntawm lub sab sauv thiab qis limiters yuav tsum yog thiab rhiab heev.
f. Tus nuv nres txiv ntoo yuav tsum tau fastened securely.
g. Tus nuv yuav tsum yoog raws txoj kab rov tav thiab ntsug.
h. Tus nuv pulley yuav tsum tig flexibly.
i. Cov hlua hlau yuav tsum tsis muaj cov kab nrib pleb, ua kom zoo nkauj ntawm lub nruas, thiab tsis muaj cov cim ntawm kev sib cais los ntawm lub ruby groove, twisting, overlapping buckles, thiab lwm yam, thiab zoo lubricated.
j. Tsis muaj qhov txawv txav hauv cov khoom nqa nqa.
k. Qhov chaw ua haujlwm kub ntawm hluav taws xob hoist yog -25- ntxiv rau 40 degree
l. Hluav taws xob hoists tsis haum rau cov chaw uas muaj cov roj corrosive lossis cov av noo ntawm cov txheeb ze ntau dua 85 feem pua, thiab tsis tuaj yeem hloov cov khoom tawg-pov thawj. Nws tsis haum rau nqa cov hlau molten los yog cov khoom lom, flammable thiab tawg.
2. Lub tshuab hluav taws xob hoist tsis pub nqa thiab nqa cov khoom hnyav rau sab, thiab txwv tsis pub thauj khoom ntau dhau.
3. Thaum lub sij hawm siv, tus neeg teb xov tooj yuav tsum nco ntsoov xyuas seb cov hlua hlau yog buckled, knotted, grooved, hnav, thiab lwm yam. Yog hais tias nws tshwm sim, nws yuav tsum tau muab tshem tawm nyob rau hauv lub sij hawm, thiab txoj hlua qhia thiab txwv hloov yuav tsum tau xyuas ntau zaus kom pom tias nws muaj kev nyab xeeb thiab txhim khu kev qha.
4. Tsis txhob siv cov khoom siv dag zog kom tsis txhob nqa cov khoom hnyav lossis tsis ua haujlwm ntawm cov khoom siv hauv kev ua haujlwm txhua hnub.
5. Tom qab ua haujlwm tiav lawm, tua lub hwj chim loj thiab txiav tawm lub zog loj.
6. Cov neeg ua haujlwm tshwj xeeb yuav tsum raug xaiv los saib xyuas qhov kev ua haujlwm tseem ceeb thiab kev nyab xeeb ntawm lub tshuab hluav taws xob ib zaug ib lub lim tiam, thiab teeb meem yog tias pom.
