Kunezinhlobo eziningi zamaketanga, ezihlukaniswe zibe yindandatho eqondile, emise okwe-D kanye ne-horseshoe-shaped ngokusho kokuma kwendandatho; kunezinhlobo ezimbili zohlobo lwe-screw kanye nohlobo lwephinikhodi oluguquguqukayo ngokusho kwefomu lokuxhuma lephinikhodi nendandatho. Iphinikhodi neringi ye-screw shackle intambo. Kunezinhlobo ezimbili zezikhonkwane ku-shackle, okuyindilinga kanye ne-oval. Ixhumene kahle nembobo yendandatho futhi ingakhishwa ngokuqondile. I-shackle yohlobo lwe-D isetshenziswa kakhulu ekuxhumekeni kwe-rigging yesitho esisodwa; I-shackle yohlobo lwe-B isetshenziswa kakhulu ukubopha izitho eziningi. Amaketango ohlobo lwe-BW, DW asetshenziswa kakhulu ezikhathini lapho ukugoqa kungeke kushayele iphinikhodi ukuthi ijikeleze; I-BX, DX amaketango ohlobo lwe-DX asetshenziswa kakhulu ezikhathini lapho iphinikhodi ingase ijikeleze futhi ifakwe isikhathi eside.
I-shackle iyithuluzi lokuxhuma elisetshenziswa kakhulu emisebenzini yokuphakamisa. Isetshenziselwa ikakhulukazi izingxenye zokuxhuma ezivame ukufakwa futhi zisuswe ekuphakamiseni. Uma i-rigging isetshenziswa ngokuhambisana ne-beam, i-shackle ingasetshenziswa phezulu kweriging esikhundleni sendandatho yokuphakamisa kanye ne-lug plate ngaphansi kwe-beam. Ukuxhuma ukuze kube lula ukufakwa nokususwa. Amaketanga asetshenziswa kakhulu emandleni kagesi, ku-petroleum, emishinini, emandleni omoya, embonini yamakhemikhali, emachwebeni, ekwakhiweni nakwezinye izimboni, futhi abaluleke kakhulu izingxenye zokuxhuma ekukhuphuleni.
