1. 321 hom steel choj Bailey net txoj kab dav yog 3.7 meters;200 steel choj net txoj kab dav muaj ob hom: qauv dav yog 4.2 meters (zoo rau cov tsheb tshwj xeeb);
2. Lub staggered kev npaj ntawm kev sib koom tes ntawm chord thiab lub truss yog ntxiv dag zog los txo cov inelastic deformation los ntawm tus pin qhov clearance, thiab pre-arching txoj kev tau txais yuav zoo heev txo qhov ntsug deflection ntawm tus choj ncua.Lub 321 hom steel choj tsis tuaj yeem teem caij rau hauv txoj kev no, thiab lub deflection ntawm tag nrho tus choj yog loj dua li ntawm HD200 steel choj.
3. Cov tswvcuab ntawm cov ntsia liaj qhov rooj tau txais txoj hauv kev ntawm kev tso thiab kho ntawm lub tes tsho qhia kom nce qhov kev sib txuas ntawm cov khoom, lub tes tsho qhia yog sheared, ntsia liaj qhov rooj yog rub, kev pabcuam lub neej ntawm cov ntsia liaj qhov rooj yog txhim kho, thiab kev nyab xeeb ntawm steel choj yog guaranteed.
4. HD200 cua-resistant pas nrig yog tsim rau hauv ib hom, thiab txuas nrog lub nqaj kom txhim kho kev ruaj ntseg ntawm tus choj steel.
5. Txoj kev txhawb nqa kab rov tav ntawm HD200 steel choj yog tsau ntawm cov kab rov tav txhawb nqa thiab cov truss daim.Qhov no ua kom paub tseeb tias tag nrho tus choj tsis muaj sab khoov thiab tag nrho tus choj tau zoo nruab nrog pre-camber.
6. Steel choj Cheebtsam yog tsawg yooj yim rau kev sib dhos, disassembly, tsheb thauj mus los thiab cia.
7. Nyob rau hauv cov ntaub ntawv ntawm kev ncua loj, 321 hom steel choj pom tseeb tshaj HD200 steel choj nyob rau hauv tus nqi ntawm cov hlau siv.321 hom steel choj ua ke daim ntawv yog: peb kab ntawm ib-txheej reinforced hom, thiab nws qhov hnyav yog: 57.2 tons.Lub HD200 steel choj ua ke daim ntawv yog: ob-kab ib-txheej reinforced hom, nws qhov hnyav yog: 54.8 tons, uas txuag 2.4 tons ntawm steel tshaj 321 hom steel choj, thiab nws steel choj Bailei muag net txoj kab kuj nce mus rau 4.2 meters. , uas yog yooj yim rau tsheb.los ntawm.
8. Thaum qhov tshwj xeeb load yuav tsum, hom 321 tsis tuaj yeem dais, thiab HD200 steel choj tuaj yeem hla qhov siab tshaj plaws ntawm 60 tons.
