Kev sib txhuam- hom siab- lub zog bolts: Haum rau kab teeb - mus rau -kem kev sib txuas hauv cov qauv steel, khoom siv -web beam kev sib txuas, hnyav- lub luag haujlwm crane nqaj txuas hauv kev lag luam, thiab kev sib txuas rau lub tshuab braking thiab cov qauv tseem ceeb uas yuav tsum tau ua kom muaj zog.
Cov kabmob -hom siab- lub zog bolts: tuaj yeem siv rau kev sib txuas ntawm cov khoom sib txuas hauv cov qauv uas muaj cov khoom siv zoo li qub (qhov twg me me slippage tau tso cai) los yog hauv cov khoom tsis ncaj qha rau cov khoom hnyav.
Tension-hom siab- lub zog bolts: Cov no qhia tau tias tsis tshua muaj zog qaug zog hauv qhov nro; nyob rau hauv dynamic loading, lawv load- bearing muaj peev xwm feem ntau yuav tsum tsis txhob ntau tshaj 0.6P (qhov twg P yog lub tso cai axial quab yuam ntawm lub bolt). Yog li ntawd, lawv tsuas yog tsim nyog rau cov ntawv thov thauj khoom zoo li qub, xws li flange pob tw pob qij txha hauv cov tswv cuab compression lossis T-joints.
