Inner Stock Rail Fastening IBaV

The modern rail fastening in the switch area is a design optimised for the expected load with extended functions. Regarding its fastening properties, it corresponds to a common rail fastening in the track and exhibits high reliability. The plate is designed to meet the requirement for improved environment protection and minimised maintenance effort.

The pace-setting development enables the integration of an elastic switch roller in the slide chair of the inner stock rail fastening IBaV – System Brandenburg.

 

Design and Function

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.

 

Application

The inner stockrail fastening IBaV – System Brandenburg can be used for all turnouts and is available for almost all commonly used rail profils. 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 switch 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.
