WHAT IS FASTENING W14 TYPE SYSTEM?
The rail fastening system W14 type is designed for railway lines representing the A, B, C and D category according to EN 13481-2: 2017 norm with a maximum permissible axle load of 260kN. Depending on the requirements of the client, the system is provided with a rail pad of high or low static stiffness. Due to the mid-loop of the clip, which is situated over the rail foot, the rail fastening is characterized by additional elasticity. This eliminates the possibility of overloading the clips' arms and their plastic deformation as well as prevents the rotation of the rail. The system meets the requirements of norm EN 13481-2: 2017.

COMPONENTS OF FASTENING W14 TYPE SYSTEM:

 

COMPONENTS OF FASTENING W14 TYPE SYSTEM

1. Dowel Sdu9 or Sdu25
2. Angled guide plate Wfp 14k 12
3. Spring clip Skl 14

4. Sleeper screw + fat washer Ss25/Ss35 + ULS7 and DHS25/DHS35 + ULS7

5. Rail pad Zw660a, Zw654a, Zw649a, Zw860t, Zw854t, Zw849t

Screw spike:
Screw spike, also known as Tirefond or sleeper screw, and it is called timber screw in America. Screw spikes are used for fastening baseplates and rails to timber sleepers.
Screw spikes are used for indirect or direct fastenings of rails on concrete and wooden sleepers. 
We can supply a wide range of screw spikes, manufactured to international standards according to BS, ASTM and DIN, and others.
The screw spikes can be tailored to meet the needs of any track system.
Some types of screw spike we produced are ASTM A66-87 screw spike, UIC864-1 screw spike (Ss series Ss8, Ss23, Ss25, Ss35, Ss36, DHS35 etc), 3V screw spike meet to NF F50-006, to name just a few.

Screw dowel:
Screw dowel is produced with the material HDPE or PA66, it is pressed in concrete sleeper and used in combination with the screw spike. We have screw dowel Sdu9, Sdu25
 
SKL tension clamp:
We have SKL1, SKL3, SKL12, SKL14, material used is 60Si2CrA or 38Si7

FEATURES AND ADVANTAGES OF W14 TYPE SYSTEM

Installation, all of the components can be pre-assembled to the sleeper before taking it to the construction site

The construction and characteristic of spring clip Skl 14 limiting the rotation of the rail when running through a narrow track curves

Rails high rail resistance value to longitudinal displacement, which prevents the dangerous deformations of the rail in the contactless tracks

Use of different widths of angled guide plate Wfp14k, enables horizontal adjustment in the range ±5
Interchangeability of all fastening elements
Material of the rail pad: EVA, TPU
