Unimat 09-4x4/4S Dynamic

Successful launch of the turnout tamping machine in Poland

The new Unimat 09-4x4/4S Dynamic has been in operation for the Polish track maintenance contractor Torpol S.A. since 2016. A major reason for this successful launch was perfect support during commissioning and delivery of the machine.

Modernisation of the rail network in Poland has greatly advanced in recent years. Between 2014 and 2015 alone, 697 turnouts were renewed. Understandably, the question arose if there was a machine concept that would help to manage this task more efficiently. A state-of-the art response was given by the track maintenance contractor Torpol S.A., which decided in 2014 to purchase a new Unimat 09-4x4/4S Dynamic turnout tamping machine. It is one of the first machines in the world to enable continuous working action and both 3-rail lifting and 4-rail tamping. In addition, a dynamic track stabiliser is integrated in the machine.

Comprehensive support from the very beginning

In order to unlock the full potential of complex machines of this kind from their first use, Deutsche Plasser stuck to its tried and tested policy of providing comprehensive support from the outset. Torpol S.A.’s machine operators were invited to the training centre of Plasser & Theurer in Linz/Austria and to the training centre of Deutsche Plasser in Bingen/Germany to familiarise them with the theoretical and practical aspects of operating the machine. The training sessions on the 3D simulator, in particular, greatly helped to gain practical experience in handling the machine.

Service engineers on-site during first operations

From commissioning onwards, two service engineers of Deutsche Plasser were present. When in April 2016 the machine operated on a first real work site on the premises of Torpol S.A. in Konin, service engineers of Deutsche Plasser were there to provide support.

Not least owing to this first-class support, the Unimat 09-4x4/4S Dynamic has been deployed with great success and performed roughly 300,000 tamping insertions since then.

Equipped for Poland and Norway

Since Torpol S.A. is also active internationally, the Unimat 09-4x4/4S Dynamic has been equipped with all the technical and safety-related components necessary for its operation in both Poland and Norway.

Wojciech Musiał, Branch Manager of Deutsche Plasser in Poland: “The Unimat 09-4x4/4S Dynamic is the first machine of its kind in Poland. It was all the more important, therefore, to provide intensive support to Torpol S.A. from the very beginning to ensure its success. Today we may say that we managed to do this with aplomb!“
