Our first machine has already carried out 1,958,800* tamping cycles within four years. The rotation speed modulation minimises the wear on the work units, which carried out 1.3 million tamping cycles before requiring an overhaul for the first time.

For more than half a century, Plasser & Theurer has been a part of the railway system and has contributed considerably towards the safety and reliability of railways throughout the world. In this time, the company has sold more than 17,000 machines and supplied them to 110 countries. The efficient and cost-effective all-rounders from Plasser & Theurer’s Unimat 09-4x4/4S series have been crucial to this success story.

Versatile application - international operation

All relevant work processes combined in one machine: The Unimat 09-4x4/4S closes the gap between compact machines and large universal tamping machines. It produces particularly durable, regulated and process-reliable tamping results during its entire life cycle - even when the ballast bed is in poor condition. Modular expandability gives you the opportunity to optimally adapt machines to any operational strategy or market requirement, using new features, such as the E³ drive system and the PlasserSmartTamping assistance system. Machine operators particularly appreciate one feature of the Unimat 09-4x4/4S: Regardless of possible expansions, the machine meets any requirement in plain track and in the turnouts, even when the radius is particularly tight.

The continuous working action reduces wear on the brakes, cardan shafts and gearboxes. At the same time, it increases the machine’s output. The rotation speed modulation makes it possible to penetrate old and hardened ballast beds more easily and extends the service life of the work units.

For us at DB Bahnbau Gruppe there was no doubt that it had to be a continuous action machine. Its advantages make it stand out in day-to-day operation: universal application,high speeds also on plain track and low levels of stress for the staff. Within the first six months from its delivery the machine has tamped 104 turnouts.
