Inner stockrail fastening - Brandenburg System

Inner stockrail fastening Brandenburg System with integrated switchpoint roller

Modern rail fastenings in the area of the switch device are designed such that they fulfil load requirements on the one hand and carry out additional functions on the other hand. They are highly reliable and their
properties correspond to the ones of fastenings in the running track.
The demand for improved environmental protection and less mounting and maintenance expenditure is fully met by the ribbed plate.
It is possible to integrate a resilient switchpoint roller in the slide chair of the inner stockrail fastening - Brandenburg System.

Structure and function of the inner stockrail fastening Brandenburg

A slide chair separated from the ribbed plate fastens the foot of the stock rail on the ribbed plate by means of a spring at a force of at least 10 kN.
As there are pads below the stock rail and also below the slide chair, the switch rests on the slide chair under conditions similar to track fastening conditions.

Creep resistance values of the stock rail are also similar to the values of the track.

A protection against "tilting" secures the position of the stock rail at any time.

Use of the Inner Stockrail Fastening Brandenburg

The inner stockrail fastening Brandenburg can be used for all turnouts and is available for almost all commonly used rail sections. For elastically installed turnouts of different stiffness grades solutions are offered as well.
As the slide chair is separated from the ribbed plate, the stock rail is easy to install and in case of wear the slide chair can be exchanged without problems.

The slide-chair plate with the integrated resilient switchpoint roller and the corrosion-resistant, coated slide plates and slide-chair plates make the turnout a low-maintenance product. The most important advantage of this integrated solution is that no components are stored in the sleeper spacings any more, which in turn makes track maintenance a lot easier.

Advantages

  • Elastic bearing of stock rail and switch
  • Creep resistance of the stock rail fastening is the same as for rail fastenings in the track
