Rotation speed modulation of tamping units

In addition to noise reduction, the rotation speed modulation enables fuel savings of up to 10 %. Moreover, it significantly reduces wear on the tamping units.

Combined levelling and alignment laser

During track tamping, the combined levelling and alignment laser guides the tamping machine according to the precision method. Using this method, the laser beam is displayed on the laser receiver camera (at the tamping machine) and analysed according to its position.
The combined levelling and alignment laser also allows producing a particularly accurate turnout geometry. In doing so, the ideal geometric position of the turnout (in the through rail) is recorded along the laser reference line.


In 110 countries

You can choose from a complete range of tamping units for all track and turnout maintenance applications, classified according to output and performance requirements. They are available in various designs and sizes: the perfect fit for all our tamping machines.


Environmentally friendly lubricants  

High-performance, green lubricants are key to reducing our carbon footprint. Plasser & Theurer paved the way for this approach 22 years ago using organic lubricants manufactured by PANOLIN. 


Continuous working action - increased output during tamping

30 years ago, a technical concept evolved from an idea to increase the cost efficiency of tamping work. It has continued to set standards even to this day. The technical basis was laid early on: the U-shaped design of the machine's main frame and the positioning of the work units between the axles. However, it was always necessary to accelerate and brake the entire machine mass to be able to tamp. Due to the separation into a continuously moving main frame and a cyclic-action subframe, less than 20 % of the machine mass has to be accelerated and braked.

The measuring system for documenting track geometry

The digital recording processor (DRP) records, evaluates, and displays various track parameters, such as the longitudinal level, alignment, crosslevel, and twist. The real-time display on the panel PC enables immediate analysis of the individual channels and makes it possible to describe individual events using the comment function.
