Austroroll® MFR -  The maintenance-free roller device for frogs with a moveable point

The principle of functioning is similar to that of the proven Austroroll rolling device in the switch blade area. However, in the frog, the very cramped space conditions do not enable any direct installation of rollers at or under the moving frog point.

The function of lifting the frog during the setting procedure is assumed by a displacement bracket. This displacement bracket is attached under the frog and guided by two rollers mounted to the side of the wing rails. In its end position, the frog tip rests securely on the sliding chairs.  Only at the start of the setting process the bracket lifts the frog tip, transports it to the opposite end position and replaces it there down again.

A lubrication of the slide plates is therefore no longer necessary.

Austroroll®-HSR significantly reduces the changeover resistance also in the frog area.
