Advantages of MULTI-sleeper tamping

MULTI-sleeper tamping machines offer two obvious advantages: high working speeds and measurable increases in tamping quality. 

Short track possessions during maintenance tamping are not the only scenario in  which continuously working MULTI-sleeper tamping machines show their full potential. 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. Their longer frames decrease bending stress in rails. And the subframe bogie that fixes them in place prevents elastic rebound of the track after tamping, lining, and lifting. 

3X tamping unit

More speed and consistent quality with the 09-3X

The key component of the 09-3X is the 3-sleeper tamping unit. It allows the machine to tamp three sleepers simultaneously during one single tamping process. Whether it’s maintenance operation or tamping newly laid track: compared to the continuous 2-sleeper tamping machine, the 09-3X model increases output by 30 to 40 %. And that’s not its maximum performance, but rather, an average value.

In 1996, the 3-sleeper tamping technology was introduced for the first time. Ever since, the concept has been used around the world and continues to live up to its reputation. Globally, the name 09-3X is synonymous with simplified worksite logistics, optimal utilisa- tion of track possessions as well as reduced costs for administration and staff.

  • SIMPLIFIED WORKSITE LOGISTICS: better use of track possessions
  • WORK-SEQUENCE CONTROL: fully automatic, semi-automatic, or manual

2X tamping unit

The continuous-action 2-sleeper classic 09-2X and 09-2X/SD

The required tamping performance per time unit determines the size of the tamping unit. In that sense, a high annual output may be just as crucial as short track possessions on high-capacity lines. The 09-2X and 09-3X models are equipped with the same frame design, and the 09-2X employs 2-sleeper working technology. This 2-sleeper technology provides optimal conditions assuming tamping at maximum speed is less of a priority. Our 09-2X model, with its compact 2-sleeper tamping unit, will win you over: more than 1,200 machines currently in operation attest to its success. You have the choice of either a classic 2-sleeper tamping machine or a machine which can switch to tamping individual sleepers using 1X mode (09-2X/SD).

Tamping track with irregular sleeper spacing

Flexibility that pays off –  adapt tamping units to target  your market’s needs

Plasser & Theurer’s proven tamping technology can also be used under almost all operating conditions. 
Sometimes there are sections of track with irregular, heterogeneous sleeper positioning. That is why Plasser & Theurer offers customised tamping units for different types of track. Thanks to these special models with additional adjustment mechanisms, there is nothing you can’t handle. You are always in complete control and achieve optimum results, no matter how great the deviation is between the sleeper types and spacing.

Customisation options:

  • Automatic detection of sleeper spacing
  • Thrust flaps which adjust the opening width of tamping units
  • Complete flexibility with 1-sleeper tamping
  • Cyclic-action tamping possible

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.
