Chain slings yog ib hom rigging uas txuas nrog cov hlua hlau txuas. Raws li nws daim ntawv, muaj ob lub ntsiab: welded thiab assembled. Raws li nws cov qauv, nws muaj monobloc thiab multibloc thiab yog ua los ntawm cov hlau zoo hlau. Nws lub neej ua haujlwm ntev thiab khoov yooj yim ua rau nws haum rau kev siv loj thiab nquag. Cov ceg tawv tawv thiab ntau qhov sib xyaw ua ke tuaj yeem txhim kho kev ua haujlwm zoo thiab txo cov nqi thiab lwm yam.
Kev ceev faj rau kev siv chain sling
1. Tsim kom muaj tus cwj pwm nqa zoo thiab npaj yuav ua li cas dai, nqa thiab tshem tawm ua ntej nqa haujlwm.
2.Kev Npaj: Txiav txim siab qhov hnyav thiab qhov nruab nrab ntawm lub ntiajteb txawj nqus ntawm cov khoom yuav tsum tau nqa, nyeem cov ntaub ntawv nrog rau kom zoo, thiab kos cov ntsiab lus ntawm qhov nqa thiab qhov hnyav. Tsuas yog tom qab txiav txim siab qhov nruab nrab ntawm lub ntiajteb txawj nqus tuaj yeem dai rau hauv txoj haujlwm raug!
3.Tus neeg tsav tsheb crane yuav tsum tau ceeb toom txog qhov hnyav ntawm cov khoom yuav tsum tau nqa.
4.Lub crane nuv yuav tsum tau dai vertically saum nruab nrab ntawm lub ntiajteb txawj nqus ntawm cov khoom raug tshem tawm.
5.Lifting lifting khoom yuav tsum tsis txhob tsuas yog zam kev puas tsuaj rau lub lifting khoom, tab sis kuj tiv thaiv kev puas tsuaj rau lub rigging nws tus kheej.
Txhawm rau kom tsis txhob muaj kev sib hloov lossis poob, cov xwm txheej hauv qab no yuav tsum tau ua raws:
A)Nyob rau hauv cov ntaub ntawv ntawm ib leeg-legged rigging, lub lifting point yuav tsum nyob rau hauv vertically saum nruab nrab ntawm lub ntiajteb txawj nqus ntawm lub lifting khoom.
B)Nyob rau hauv cov ntaub ntawv ntawm ob-legged rigging, lub lifting ntsiab lus yuav tsum nyob rau ntawm ob sab ntawm lub lifting khoom, nrog rau lub lifting point saum toj no qhov chaw ntawm lub ntiajteb txawj nqus.
C)Nyob rau hauv cov ntaub ntawv ntawm peb-thiab plaub-legged rigging, lub ncua kev kawm ntawv cov ntsiab lus yuav tsum nyob uniformly nyob rau hauv kab rov tav dav hlau ntawm qhov chaw ntawm lub ntiajteb txawj nqus ntawm lub lifting khoom thiab saum toj no qhov chaw ntawm lub ntiajteb txawj nqus ntawm lub lifting khoom.
Kev saib xyuas yuav tsum tau them rau lub kaum sab xis lifting (nyob nruab nrab ntawm txoj kab ntsug thiab lub lifting ceg): qhov ntau dua lub lifting lub kaum sab xis, qhov tsawg dua qhov lifting muaj peev xwm. Lub kaum sab xis nqa yuav tsum tsis pub tshaj 60 degrees!
Yog tias peb-lossis plaub-legged saw rigging yog siv los nqa cov khoom tsis sib xws, qhov ntsuas qhov hnyav rau txhua ceg yuav tsum tau suav nrog siv ob txhais ceg nrog lub siab tshaj plaws nqa lub kaum sab xis rau nqa cov khoom. Thaum lub kaum sab xis ntawm ob txhais ceg sib txawv, tsuas yog ib txoj hlua yuav tsum tau siv los xam cov nqi thauj khoom rau txhua ceg nqa tag nrho cov khoom nqa.
