Different types of spring shackles
Elastic attraction of forces imposed on the rail and their transfer to transverse is the duty of shackles. The shackles keep the rail permanently on transverse and divided into two groups concerning their installation manner:
1. Self-locking elastic shackles
2. Shackles that are connected to traverse by screw
The advantages of spring shackles in railways is safety and reliability, long fatigue life (more than 5 million cycles) and high axial load tolerance and they are easily used for installation or replacement of rail.
Concrete traverse screw
This screw is used in systems where spring shackle is connected by screw to traverse. This screw is produced based on UIC864-1 standard.
Small and big brackets
These pieces are used in concrete traverse and have the role of pre-stressing force transfer. They are made from ST52-3 steel.
