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.

Split Head technology

Split Head tamping units for work on tracks, turnouts, and crossings are tamping units divided in longitudinal direction of the machine. Each of the two work unit halves can be lowered and put into action separately from the other. Additionally, both work unit halves, depending on the design, can be laterally displaced together or individually.
For operation on sections of plain track the two halves are locked together to form a tamping unit for tracks.

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 protection and sound-insulating features

In the area of the work units, tamping machines can be equipped with lateral noise protection panels. This is important for the operation in densely built-up areas, for instance in Japan. 
To counteract possible generation of dust during the tamping process and to provide the operator with good visibility, particularly when using noise protection panels, a water spray system can be installed at the tamping units. It is activated when the tamping units are lowered and switched off when they are lifted.

Digitisation

Plasser Datamatic – MachineConditionObserver
Controlling operation and servicing digitally

Fleet and maintenance managers can access information on the condition of their machines at any time, allowing for condition-based maintenance and enabling them to plan required measures ahead of time. 
The exact machine position can be accessed at any time, facilitating operations planning and refuelling. The management receives informative reports, providing the basis for strategic decisions.
