Advantages of multi-sleeper tamping

However, continuously working MULTI-sleeper tamping machines show their full potential not only in short track possessions during maintenance tamping. Machines in the X series also offer advantages when laying new track, for example, following extensive track rehabilitation. They are designed for high lifting and lining forces. As lifts take place in multiple work stages, this also means the machine’s increased output allows you to complete construction noticeably faster.

For quality reasons: MULTI-sleeper tamping units provide more uniform working action, which translates into higher maintenance quality. Owing to a longer frame, bending stress of the rails decreases. And the subframe bogie that fixes it in place prevents elastic rebound of the track after tamping, lining, and lifting.

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.

4-rail tamping

This mode uses four tamping unit segments. The outer segments can be slewed out far enough that the long bearers of the diverging rail in the turnout can also be tamped. This is an ideal supplement to automated synchronous 3-rail lifting. Positioned on transverse guide columns, the inner tamping units can be displaced laterally. This enables them to be operated in the area inside and outside the respective rails. All four tamping units can be turned and thus adapted to the slanting position of the sleepers.

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.

Fit for the future of the railway

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.

PlasserSmartTamping – The Assistant

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.
