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.
When it comes to tamping the ballast bed, our aim is efficiency and sustainability. Homogenous compaction is not enough. Our aim is to compact the track ballast as much as possible, thereby ensuring a stable track geometry, anticipating settlements, and maintaining the target geometry in the long term. On top of it all, we offer the Dynamic Track Stabiliser: it anticipates initial settlements in a controlled manner, with spatial compaction making the track geometry last longer.
Combined with Dynamic Overlifting, we target the “track’s memory” to prevent faults from reoccurring.
Our high-quality tamping tines allow higher kilometre outputs and have to be replaced less often. In both cases, our original tamping tines have set the standard. Their design is crucial: they are produced as monobloc components forged in one piece and coated with a tungsten-carbide armour for all surfaces that come into contact with the ballast.
The latest track maintenance machines use both the electrical energy from the contact wire and batteries to power the working drive. Our new E³ drive technologies reduce local emissions - of both pollutants and noise – to a minimum on the work site.
At Plasser & Theurer, we have taken the classical tamping machine to a new level. The Unimat 09-4x4/4S E³ uses the electrical energy from the overhead contact line not only for electrical traction during transfer travel. It is also used to power the tamping unit electrically for the first time. The crucial working parameters remain unchanged. If there is no overhead contact line available for current collection, we use a diesel-electric generator to supply electrical power.
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 digital future of turnout tamping has begun. “PlasserSmartTamping - The Assistant” is a turnout tamping assistance system that has revolutionised automation in tamping machines. It simplifies tamping in turnouts and crossings, with no extra measuring run needed. Particularly in times where there is a dearth of experienced staff, the system gives infrastructure operators security.
70 years of experience in tamping technology feed into the digital tamping assistant.
