China WJ-2 type of spring rail fastener system

China WJ-2 Elastic Clip Rail Track Fastener System

The WJ-2 type of spring rail fastener system is used for seamless tracked ballastless track fasteners, requiring a small longitudinal resistance of the line. It is a WJ-2 type elastic strip fastener system for the small-resistance of the ballastless track which is only used on the bridge in China. It is suitable for laying 60kg/m rail and concrete monolithic track bed on the standard gauge of the ballastless track on the bridge, meeting the high-speed railway.

Fastener Parts:
WJ-2 type fastener system consists of nut, flat washer, W5 spring bar, T bolt T3, WJ2 gauge baffle, WJ-2 embedded iron seat, WJ-2 insulation gauge block, WJ-2 rail underlay plate, WJ-2 iron pad Board, WJ-2 iron tie plate under the elastic pad, WJ-2 gauge baffle down high pad and WJ-2 preset heightening pad.

Application:
The elastic clip V-type fastener system is suitable for laying 60kg/m rails on high-speed railways with ballast tracks, among which:

Fastener Parts Mechanical Requirement:

• Each set of fasteners buckle pressure ≥ 20 kN;

• The longitudinal resistance of rails for each set of fasteners shall not be less than 10 kN;

• The fastener system shall not be damaged after 3 million load cycles, and the gauge length shall be less than 6 mm;

• Adjusting the left and right position of the single rail: -6 to +4 mm, adjusting the gauge: -12 to +8mm; adjusting the height of the rail: -4 to +16 mm;

• System flexibility: static stiffness of the under-rail pad 50kN/mm;

• The pull-out force of the embedded iron seat is not less than 70 kN.

• 
  

• 
  

The requirement for rail fasteners on the bridge to lay seamless lines. Under the rail and under the pad, there is a height-adjusting pad, the fastener has a gauge adjustment of +10mm to -12mm, and the rail height adjustment of +30mm to 0mm. The longitudinal resistance of each fastener rail is 6.5kN ± 0.5kN. If structural measures are taken, it can be reduced to 3.6kN ± 0.4kN, and the longitudinal resistance of the rail is lower than the normal fastener 7kN.
