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.

Tamping tine and ballast: teaming up

Thanks to a brand new measuring and analysis method, it is now possible for the first time to observe the movement behaviour of ballast throughout the entire tamping process. In addition, the method provides an unprecedented level of detailed insight into the ballast condition. 

Reliability

Quality of tamping tines

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. 

Sustainability

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.

Noise measurement

When the tamping units, which have electrically powered vibration shafts, are raised in idle mode, the noise is reduced by more than 20 dBA. The noise created in idle mode is 62 dBA, which is equal to the noise level of a normal conversation in the office.

Digitisation

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.
