Lub shackle yog ua los ntawm cov carbon ua haujlwm zoo los yog txheej txheem kev cai zam thiab kev kho cua sov, nrog muaj peev xwm loj, hloov tau yooj yim thiab txhim khu kev qha.
Muaj ntau hom shackles, uas muab faib ua lub nplhaib ncaj, D-puab thiab horseshoe-puab raws li cov duab ntawm lub nplhaib; Muaj ob hom ntsia hlau hom thiab hloov tau PIN hom raws li kev sib txuas daim pin thiab ntiv nplhaib. Tus pin thiab ntiv nplhaib ntawm cov ntsia hlau Shackle yog threaded. Muaj ob hom pins hauv shackle, uas yog ncig thiab oval. Nws yog qhov sib chwv nrog lub nplhaib nplhaib thiab tuaj yeem rub tawm ncaj qha. D-hom shackle yog siv rau ib leeg-limb rigging txuas; B-hom shackle yog tsuas yog siv rau ntau txoj hlua khi sib. BW, DW hom Shackles yog siv nyob rau hauv qee zaus uas rigging yuav tsis tsav tus pin pin kom tig; BX, DX ntaus Shackles yog siv nyob rau hauv qee zaus uas tus ncej PIN tuaj yeem tig thiab lub zog ntev.

Lub shackle yog cov cuab yeej siv txuas ntxiv hauv kev nqa cov haujlwm. Nws yog tsuas yog siv rau cov chaw sib txuas uas nquag ntsia thiab muab tshem tawm hauv kev xav. Thaum cov rigging yog siv nyob rau hauv kev sib xyaw nrog cov nqaj, lub shackle tuaj yeem siv nyob rau sab saum toj ntawm lub rigging tsis txhob nqa lub nplhaib thiab cov ntaub nyias nyias nyob hauv qab nqaj. Kev sib txuas rau kev teeb tsa yooj yim thiab tshem tawm. Shackles tau dav siv hauv hluav taws xob muaj zog, roj av, tshuab cua, kev lag luam siv tshuaj lom neeg siv tshuaj, thiab lwm yam kev lag luam, thiab yog ib qho tseem ceeb txuas rau hauv hoisting.
