Yiziphi izinhlobo ezivamile zemijondolo

Ama-shackles asetshenziswa kaningi kumasayithi wokusebenza ahlukahlukene wokuphakamisa, asetshenziswa ikakhulukazi njengezingxenye zokuxhuma, nethuluzi elibalulekile lokuxhuma phakathi kokugibela nezinto okufanele zikhuphukele. Umjondolo wenziwa ngesakhiwo se-carbon esezingeni eliphakeme noma isakhiwo se-alloy esakha kanye nokwelashwa okushisa, ngamandla amakhulu okuthela, aguquguqukayo futhi athembekile.
Kunezinhlobo eziningi zemijondolo, ezihlukaniswe ngendandatho eqondile, enziwe nge-D-shape ne-horseshoe ebunjiwe ngokuya ngesimo sendandatho; Kunezinhlobo ezimbili zohlobo lwesikulufa nohlobo lwe-PIN eguquguqukayo ngokuya ngefomu lokuxhuma le-PIN ne-Ring. I-PIN ne-Ring of the Screw Shackle yenziwe. Kunezinhlobo ezimbili zezikhonkwane ekuhlaseleni, okungukulingisa kanye okusaqanda. Kukuxhumana kahle nomgodi wendandatho futhi kungakhishwa ngqo. Uhlobo lwe-D-Type lusetshenziselwa ukuxhumeka kwe-ling-limb Uhlobo lwe-B-Type lusetshenziselwa kakhulu ukugibela imilenze eminingi. Bw, hlobo hlobo imijondolo lusetshenziswa ikakhulukazi ezikhathini lapho i-rigging ingeke iqhube i-pin shaft ukuze ijikeleze; I-BX, imijondolo ye-DX Type isetshenziswa ikakhulukazi ezikhathini lapho ishaft ye-PIN ingashintsha khona nokufakwa kwesikhathi eside.

Umjondolo yithuluzi lokuxhuma elisetshenziswa kakhulu ekuphakamiseni imisebenzi. Isetshenziselwa ikakhulukazi izingxenye zokuxhumeka ezifakwe kaningi futhi zisuswe ekuphakameni. Lapho i-Rigging isetshenziswa ngokubambisana nogongolo, umjondolo ungasetshenziswa phezulu kwesigcawu esikhundleni sendandatho yokuphakamisa kanye neplate ye-lug ngaphansi kogongolo. Ukuxhumeka kokufakwa okulula nokususwa. Imijondolo isetshenziswa kabanzi kumandla kagesi, u-petroleum, imishini, amandla omoya, imboni yamakhemikhali, amachweba, ekwakhiweni nasezimbonini, futhi zibaluleke kakhulu zokuxhuma ezimbonini.
