Puas yog ib qho s20 rail seem ncaj qha hloov ASCE 40 khiav?
Cov lus teb luv luv yog tsis muaj. IbS20 rail seemtsis tau ncaj qha hloov ib qhoASCE 40 txoj kev. Thaum ob qho tib si siv nyob rau hauv lub teeb-lub luag haujlwm kev lag luam thiab kev siv mining, lawv yog cov qauv thoob ntiaj teb sib txawv-DIN 5901 (European) rau S20 thiab ASCE (Asmeskas) rau ASCE 40. Lawv muaj qhov sib txawv hnyav, qhov siab, thiab lub hauv paus dav, ua rau lawv lub cev tsis sib haum rau kev hloov pauv ncaj qha "{6}.
- Qhov hnyav hnyav sib txawv:S20 steel rail hnyav yog 19.80 kg / m (~ 13.3 lb / yd), thaum ASCE 40 hnyav 19.84 kg / m ib yard, uas hloov mus rau kwv yees li 39.68 kg / m. ASCE 40 yog ze li ob zaug hnyav li S20.
- Dimensional Mismatch:S20 rail profile yog 100 hli siab, thaum ASCE 40 yog kwv yees li 89 hli (3.5 nti) siab. Qhov 11 hli qhov siab qhov sib txawv no yuav tsim qhov "kab ruam" txaus ntshai ntawm txhua qhov sib koom ua ke.
- Fastener Incompatibility:Lub hauv paus 82 hli ntawm S20 rail qhov ntev yog qhov nqaim ntau dua li 89 hli puag ntawm ASCE 40. Cov rail clips, spikes, lossis baseplates rau ASCE 40 yuav tsis ruaj ntseg tuav lub S20 rail.
- Load Capacity:Vim yog qhov sib zog loj, S20 rail load peev muaj qis dua li ntawm ASCE 40. Hloov ASCE 40 nrog S20 tuaj yeem ua rau kev ua haujlwm tsis zoo yog tias cov txheej txheem qub tsim los rau qhov hnyav dua ntawm ASCE 40.
GNEE RAILmanufactures DIN thiab ASCE profiles rau nruj tolerances. Txawm li cas los xij, nws yog ib qho tseem ceeb los xyuas koj qhov uas twb muaj lawmS20 rail kos duabthiab qhov system specifications. Kev sim sib xyaw cov qauv no yam tsis muaj kev hloov pauv tshwj xeeb thiab hloov kho cov txheej txheem fastening yuav cuam tshuam txog kev nyab xeeb thiab kev ua haujlwm ntawm koj txoj kev taug.
Specifications ntawm DIN 5901 S20 RAIL thiab ASCE 40 Rail
DIN 5901 S20 thiab ASCE 40 yog ob qho tib si lub teeb -cov haujlwm steel rails feem ntau siv rau kev lag luam crane khiav, mining, thiab kev siv tsheb ciav hlau. Thaum lawv muaj ze li qhov hnyav zoo ib yam, lawv cov profiles thiab cov qauv ntsuas qhov sib txawv.
DIN 5901 S20 Rail Specifications
Lub S20 rail yog tsim los rau German DIN 5901 tus qauv rau lub teeb rails, tsom rau kev lag luam thiab cov ntaub ntawv tuav cov ntaub ntawv.

ASCE 40 Rail Specifications
ASCE 40 rail (tseem hu ua 40 lb rail) yog tsim los rau American Society of Civil Engineers (ASCE) cov qauv, feem ntau ua raws li ASTM A1 rau North American infrastructure.

Cov qauv thiab kev nyab xeeb cuam tshuam
RAIL S20 MATERIAL SRENGTH yog qhov zoo rau nws qhov hnyav 19.80 kg / m. Hauv qhov sib piv, ASCE 40 yog tsim los rau kev thauj khoom hnyav dua. Yog tias S20 rail tau teeb tsa hauv qhov system npaj rau ASCE 40, cov kev pheej hmoo hauv qab no tshwm sim:
- Accelerated Hnav:Lub 30 hli S20 rail lub taub hau dav yog ntau nqaim dua li 47 hli ASCE 40 lub taub hau. Cov log uas twb muaj lawm tsim los rau ASCE 40 yuav muaj kev sib cuag tsis zoo, ua rau "nceb" sai thiab hlau qaug zog ntawm S20 lub taub hau.
- Joint Failure:Koj siv tsis tau S20 rail fishplate ntawm ASCE 40 rail. Qhov "qhov chaw nuv ntses" qhov siab thiab cov ces kaum sib txawv kiag li, txhais tau tias cov bolts yuav tsis muab qhov tsim nyog clamping quab yuam.
- Lateral Instability:Lub hauv paus 82 hli ntawm S20 tsis ruaj khov dua li 89 hli puag ntawm ASCE 40. Nyob rau sab sab -thrust ntawm lub crane hnyav, S20 tuaj yeem qaij lossis ua haujlwm yog tias cov fasteners tsis zoo tag nrho.
FAQ
- Puas yog S20 rail tib yam li 20lb ASCE rail?
No. S20 yog kwv yees li ob zaug hnyav li ASCE 20lb rail. "S20" yog hais txog ~ 20 kg ib 'meter', thaum "ASCE 20" hais txog 20 lbs ib yard.
- Kuv puas tuaj yeem txuas S20 rail rau ASCE 40 rail?
Kev sib txuas ncaj nraim tsis pom zoo vim qhov sib txawv loj hauv S20 rail hla ntu thiab ASCE 40 profile. Lub web thicknesses tsis sib haum (7mm vs 9.5mm) ua rau nws yuav luag tsis yooj yim sua kom ua tiav tag nrho - lub zog structural weld.
- Qhov twg yog qhov zoo dua rau qhov project tshiab gantry crane?
Nws nyob ntawm qhov hnyav ntawm crane. Rau lub teeb- lub luag haujlwm nqa (2-3.5 tons), DIN 5901 S20 rail yog qhov kev xaiv zoo, raug nqi. Rau qhov hnyav dua, ASCE 40 lossis DIN profile loj dua yuav xav tau.
- S20 rail nyhav ib 'meter' piv rau ASCE 40 li cas?
S20 hnyav 19.80 kg / m, thaum ASCE 40 hnyav li 39.68 kg / m.
- Puas yog cov ntaub ntawv qib sib haum?
S20 feem ntau yog 55Q, thaum ASCE 40 ua raws li cov qauv ASTM sib txawv. Ib txwm txheeb xyuas S20 cov ntaub ntawv kev tsheb ciav hlau ua ntej sim ua kom muaj kev sib koom ua ke.
