Lub sling xaiv yuav tsum tau yoog raws li cov yam ntxwv zoo li thiab cov kev xav tau tshwj xeeb ntawm cov khoom ua haujlwm yuav tsum tau nqa. Nws yuav tsum tsis txhob siv tshwj tsis yog cov xwm txheej siv tau ua tiav.
Rau kev nqa lossis sib sau ua haujlwm loj, vim yog lub tonnage loj, cov duab nyuaj, tus nqi siab ntawm cov khoom ua haujlwm, thiab kev koom tes ntawm ntau tus neeg, qhov nyuaj thiab pheej hmoo ntawm kev ua haujlwm tau nce ntxiv. Yog li ntawd, thaum slinging loj workpieces, koj yuav tsum paub thiab tuav Ua raws li cov tseem ceeb no:
1. Saib xyuas qhov zoo ntawm lub workpiece ua ntej ua haujlwm, tuav qhov nruab nrab ntawm lub ntiajteb txawj nqus ntawm lub workpiece, thiab paub meej tias qhov hnyav ntawm lub workpiece raws li daim duab kos.
2. Xaiv cov hlua, shackles, hooks thiab lwm yam hlua khi kom raug.
3. Lub workpiece nws tus kheej muaj lifting rings los yog lifting lugs tshwj xeeb uas tsim los rau lifting. Cov no yuav tsum tau ua tib zoo tshuaj xyuas ua ntej ua haujlwm, thiab cov cables yuav tsum tau ntxiv rau tag nrho cov lifting rings.
4. Yog hais tias lub workpiece nws tus kheej tsis muaj lub nplhaib nqa, txoj hauj lwm ntawm txoj hlua taw tes yuav tsum raug xaiv kom raug. Thiab kho lub taub hau ntawm lub crane nrog qhov nruab nrab ntawm lub ntiajteb txawj nqus ntawm lub workpiece.
5. Nco ntsoov tias lub kaum sab xis ntawm txoj hlua feem ntau yuav tsum tsawg dua 90 degrees.
6. Lub kaum sab xis ntawm lub workpiece uas txoj hlua hla yuav tsum tau tiv thaiv los ntawm kaum tus neeg tiv thaiv.
7. Yuav tsum muaj cov txheej txheem nqa nqa mus sim ua ntej nqa, thiab tom qab ntawd mus rau kauj ruam tom ntej tom qab lees paub tias nws muaj kev nyab xeeb.
