Lub hom phiaj, cov duab, thiab daim ntawv thov ntawm U-bolts suav nrog:
Kev siv U-bolt: feem ntau yog siv rau cov kav dej thiab lwm cov yeeb nkab fittings lossis daim hlau, xws li kev tsim kho thiab kev teeb tsa ntawm lub tsheb hlau phaj caij nplooj ntoos hlav, kev sib txuas tshuab, tsheb, nkoj, txuas hniav, tunnels, railways, thiab lwm yam.
Cov duab tseem ceeb: semi-circular, txoj cai kaum square, daim duab peb sab, oblique daim duab peb sab, thiab lwm yam.
Daim ntawv thov ntawm U-bolts yog raws li hauv qab no: U-bolts feem ntau yog siv rau hauv cov tsheb thauj khoom kom ruaj khov tsheb chassis thiab thav duab. Piv txwv li, nplooj springs txuas nrog U-bolts. U-bolts muaj ntau yam kev siv, xws li kev tsim kho thiab kev teeb tsa, kev sib txuas ntawm cov khoom siv sib txuas, tsheb, nkoj, txuas hniav, tunnels, railways, thiab lwm yam.
Tsis tas li ntawd, U-bolts tau siv dav hauv kev lag luam niaj hnub, yooj yim rau nruab, tswj, thiab hloov, thiab muaj kev ua haujlwm seismic thiab tiv thaiv kev ua haujlwm. Thaum xaiv thiab siv U-bolts, yam xws li cov khoom siv, qhov ntom ntom, lub zog, xim, thiab lub zog compressive yuav tsum raug txiav txim siab los xyuas kom meej tias lawv tuaj yeem hloov kho rau cov kev siv tshwj xeeb thiab cov kev xav tau.
