Rautus choj Bailey, lub sijhawm tau muab nws cov qauv sib txawv, tus choj Berley, qis chord, tus ncej thiab oblique pas nrig yog welded rau hauv qis chord, cathog sib koom thaum kawg, thiab truss txuas tus pin qhov ntawm qhov sib koom ua ke. Bailey chords yog tsim los ntawm 10 raws (rov qab-rau-rov qab) ua ke, nyob rau hauv qis chord, welded ntau lub phaj puag ncig lub qhov nyob rau sab sauv thiab qis chords, muab thiab ntxiv dag zog rau chords thiab ob chav truss kev twb kev txuas ntsia liaj qhov rooj qhov, ntawm lub chord kuj siv. txhawm rau txuas lub thav duab plaub lub qhov ntsia hlau, qhov hauv ob kab lossis ntau qhov kev sib txuas truss internode. 2 qhov nrog hla ntu ntawm ob qhov kawg. Thaum siv ntau kab lossis columnberry siv los ua kab teeb, Beret trusses uas ua rau cov pob qij txha sab sauv thiab qis siv rau kev txhawb nqa yuav tsum tau txhawb nqa.
Nyob rau hauv qis chord, 4 pieces ntawm nqaj hlau phaj, sab sauv mortise, tsau beam nyob rau hauv lub dav hlau sab sauv thiab qis chord txoj hauj lwm, nyob rau hauv lub kawg ntawm cov channel steel mesh kuj oval qhov txuas pas nrig, cua. Lub pas nrig ntsug ntawm Bailey muaj cov square qhov nyob rau sab sauv thiab sab chord sab ntawm tus ncej yog siv rau cov teeb pom kev zoo los kho cov nqaj. Bailey cov khoom yog steel phaj, 270kg ib thav duab. “321” yog ib qho kev sib txuas ntawm txoj kev loj steel choj, nws cov yam ntxwv tseem ceeb yog: lub teeb lub teeb, yooj yim rau disassemble thiab sib sau ua ke, muaj zog yoog raws, siv cov cuab yeej yooj yim thiab tib neeg tuaj yeem tsim tau sai. Haum rau lub tsheb - 10, - 15, - 20, - 50, - 80 lem, nrog rau lwm 5 hom kev thauj khoom thiab thauj khoom trailer. Qhov dav ntawm tus choj carriageway yog 3.7 lab, thiab nws tau muab tso ua ke rau hauv ntau qhov kev txhawb nqa yooj yim girder choj thiab cov qauv txuas txuas txuas txuas txuas ntxiv ntawm 9 lab rau 63 lab.
