↵Rail Nabla Clip Fastening System
Daim ntawv tshaj tawm no muab cov lus qhia ntxaws ntxaws ntawm Railway Nabla Clip systems, tsom mus rau lawvtxawv inverted-V (∇) geometry, ntau-kev taw qhia quab yuam, thiab tshwj xeeb daim ntawv thov nyob rau hauv creep{2}}sensitive khiav seem. Qhov kev tshuaj xyuas txhob txwm zam tsis sib tshooj nrog cov kev sib tham ua ntej txog E-Clip, SKL nro clamps, lossis Fastclip captive designs. Qhov tsom ntawm no yogkev ua tau zoo thiab sib txawv: huab hwm coj- kev xa tawm gradient, cuam tshuam-raws li kev tswj xyuas, thiab EN13481-2 C1 tus qauv qauv.
Technical Specifications:
| Parameter | Standard Nabla Clip | High -Kev ua tau zoo Variant | NABLA C1 System | |
|---|---|---|---|---|
| Thawj Standard | TS EN 13481-5 (Hnyav thauj khoom) | EN13481-4 (Kev kub ceev) | TS EN 13481-2 Qeb C | |
| Daim ntawv thov | Mainline/concrete sleepers | Ntse nkhaus / gradients | Tsawg dua lossis sib npaug li 100km / h, Tsawg dua lossis sib npaug li 26t, R150m min | |
| Clamping Force (kab rov tav) | 8-12 KN | 13-15 KN | Tsis yog nws tus kheej ntsuas | |
| Vertical Force Component | 3-4 kN | 4-5 kN | System -nyob | |
| Khoom Qib | 60Si2MnA, 60Si2CrA | Vanadium -microalloyed | 60Si2Mn/Lwm yam kub- dov | |
| Thickness | 4.0mm los yog 4.5mm | Tsis tau teev tseg | C1 tshwj xeeb geometry | |
| Hardness (HRC) | 42-47 | 42-47 | 41-46.5 |
Performance Range:
Heavy Gradients & Bridge Approaches (>1.5%):
Qhia qhov twg longitudinal creep rog tshaj tus qauv clip peev xwm. Nabla xa40-60% zoo dua longitudinal restrainttshaj symmetric clips ntawm gradients tshaj 1.5%, ua tiav los ntawm geometric wedging txiav txim nyob rau hauv lub hauv paus lub xub pwg nyom.
Fabkis TGV Siab -Speed Lines:
Siv dav hauv LGV (Ligne à Grande Vitesse) tes hauj lwm. Tsis zoo li ntsia liaj qhov rooj - khaws cia SKL systems, Nabla tsim clamping quab yuam ntawmtswj txiv ntseej torquingntawm ob - taub hau ntsia hlau ntsia hlau loj, muab kev ruaj ntseg fastening rau 300km+ ua haujlwm .
Tram, LRT & Metro Systems:
Deployed nyob rau hauv nroog thauj mus los raulow-kev co kis. Cov yam ntxwv elastic deflection nqus cov khoom lag luam cuam tshuam, txo cov qauv- ua suab nrov hauv qhov ntu
Kev Saib Xyuas & Kev Pom Kev Ua Haujlwm
- Fatigue Life Threshold (3 lab Cycles):
- Standard Nabla clips (4mm / 4.5mm thickness, 60Si2MnA / 60Si2CrA) tau ntawv pov thawj rau3 lab lub voj voog tsis muaj pob txhaRaws li EN13481-5. Qhov no yog qis dua li hwm SKL18 / E-Clip 20mm (5 lab cycles) tab sis tsim nyog rau 26t qag load corridors .
- NABLA C1 Fatigue Certification (200 lab Cycles):
- C1 variant rau EN13481-2 Qeb C daim ntawv thov raug kuaj rau200 lab lub voj voog-ib qho kev txiav txim siab ntau dua li cov khoom siv. Qhov no qhia txog kev txuas ntxiv siab - zaus thauj khoom ntawm cov neeg caij tsheb hauv txoj kev<100km/h, not heavy haul intermittent stress .
