DFF300 clip rail fastener system
- Commodity name： DFF300 clip rail fastener system
- Description
-
The application of elastic fastening system DFF 300 is composed of ballastless track, track in tunnels and track on railway bridges. So the system can be mounted on concrete sleepers, embedded, on decks of steel bridges or it may be used to rehabilitation of existing monolithic concrete structures of ballastless track.
The DFF300 clip rail fastener system for use on desks of steel bridges consists of:
• Tension clamp Skl 15 2 pieces
• Rail pad Zw 692-6 1 piece
• Base plate Grp 21 1 piece
• Elastic base plate pad Zwp 104/NT-22,5 N/mm 1 piece
• Angled guide plate Wfp 15a 2 pieces
• Gauge adjustment plate Sp 4 pieces
• Protections pad Ulb 4 pieces
• Supporting base Gr 300-1/1:20 1 piece
• Pad Zw 480x360x5 1 piece
• T-Head bolt M24x130 2 pieces
• Washer Uls 7 2 pieces
• Hexagon nut M24 SW39 2 pieces
• Welding stud M22x70 4 pieces
• Double coiled spring washer Fe 6 4 pieces
• Hexagon nut M22-5 4 pieces
Clamping force of the fastening system DFF300 for one tension clamp is at least 1800 daN. The fastening system provides in the same time a greater elasticity by ≈ 15 mm.
The DFF 300 Vossloh rail fastening system allows a standard height adjustment by +56/-4 mm and additional adjustment by +/-15 mm.
The system allows, also, setting of the standard track gauge of +/- 8 mm and with additional +/- 10 mm.
The absence of ballast is compensated by the existence of elastic clamps Skl 15 (the clip elasticity increased to 15 mm), the pad under the rail, like the pad under the base plate and more elastic supplementary pad (with 22.5 N/mm spring coefficient). In this way the amplitude to fatigue was increased up to 2.6 mm, too.With our forging/rolling producing machines and testing center, and years of working experience on railway fasteners, Kunshan Alex Railway Fastening Co.,Ltd could make whole set of DFF300 fastening system, as well as each components of this system.
