Plasser & Theurer built the first two-axled tamping machines

at the start of the 1950s with a very short wheelbase. The

tamping units were positioned between the front axle and the

middle axle. The track was levelled and lined manually directly

in front of the tamping machine using track jacks.

The next step was the cantilever design: the tamping units

were mounted in front of the front axle to increase the

accuracy of the manual levelling process.

Further technical development was aimed at relieving the men

of strenuous manual labour. More and more functions were

incorporated into the tamping machines. Levelling, lifting and

lining were later carried out by specially developed work units

and measuring systems.

The railway administrations also placed new demands:

higher travelling speed, placement in train formation,

treatment of heavy types of permanent way with concrete

sleepers and rails weighing 60 kg/m and more. All these

demands required a new orientation in the design of thetamping machines.

A new era began in 1970: the first levelling, lining and tamping

machine of the 07 series was built with standard railway

vehicle features. All work units were positioned between the

axles, the long wheelbase permitted a smooth bending line

during the lifting and lining process.

Articulated design was introduced in 1975. This was the

beginning of the 08 series: levelling, lining and tamping

machines in compact design with integrated material car.

The Duomatic 08-32

and Plasser 08-16

today:

Four-axled machines in standard railway vehicle design,

with or without material car. The sturdy frame construction

takes account of the special requirements made by lifting and

lining forces on heavy permanent way designs. Two-axled

bogies ensure smooth running. Efficient work units and

measuring systems guarantee that an exact and long-lasting

track geometry is produced.

The availability of the machines could be increased further

by applying computer technology. Processor control also

permits simpler designs. For example, the complex design of

the front reference point for the levelling and lining chords has

been replaced by a fixed positioning; the required correction

values are sent to the computer electronically. A range of

optional equipment is also available, such as a laser sightingdevice, multi-channel recorder, air-conditioning units for work

and driving cabin.

This concept has proven reliable in countless operations.

1 Main frame

The frame is made of shaped sections, rolled profiles and

steel sheets, produced using the most up-to-date welding

methods.

2 Tamping units

Two independent action tamping units are mounted directly

in front of the rear bogie. The subframes are laterally

displaceable, which permits automatic centring of the units

over the rails during work in curves. The two heavy-duty

tamping units work according to the well-proven non-

synchronous uniform pressure tamping principle. Force

equilibrium between the tine pairs, directional vibration in the

squeeze direction and the ideal vibration frequency of 35 Hz

guarantee completely uniform tamping.

The following models are available:

Duomatic 08-32: two two-sleeper tamping units with

a total of 32 tamping tines for tamping two sleepers per

tamping cycle.

Plasser 08-16: two single-sleeper tamping units with

a total of 16 tamping tines for tamping one sleeper per

tamping cycle.

3 Sleeper-end consolidators

On request, hydraulically powered sleeper-end consolidators

can be mounted level with the tamping units or the rear

bogie. During tamping these fill up the empty gap occurring

at the ends of the sleeper during the lining process.

This permits optimum fixation of the track in lifted and lined

position.

4 Lifting and lining units

The two well-proven roller lifting and lining units lift and line

the track in one operation. The units have a total of four roller

lifting clamps. The distribution of the lifting forces and the

exact centring of the units over the rails prevent the

occurrence of tilting moments and any excessive wear on rail

fastenings. For transfer travel the units are lifted and locked.

At the start of work they are lowered onto the track and

remain there during the entire work process.

5 Drivers cabin

The front cabin houses the operating and monitoring controls

for the lining and levelling system as well as all necessary

controls for transfer travel. The cabin is reached by side steps

and sliding doors.

6 Drive and work cabin

In the rear cabin all the controls for transfer travel are

available. Moreover, the operating and monitoring controls for

controlling and monitoring the work units are clearly laid out.

The cabin is reached by side steps and sliding doors.

Both cabins are equipped with large safety glass windows.

A good view during work and transfer travel is assured. An

intercom system between the two cabins is fitted in standard

design. The high level of working comfort is achieved by

extensive soundproofing and vibration dampening. There is an

end-to-end roof between the two cabins.

7 GVA 97 and ALCBoth systems calculate the correction values for maintenance

in track curves and pass on the results continuously to the

measuring systems during work.

When the target geometry is known, the required

target data is keyed into the computer before start ofwork manually or by floppy disk externally from the

EM-SAT track survey car (only with ALC). During work

the data are passed continuously to the measuring

systems of the tamping machine.

When the target geometry is unknown, the

machines own measuring system first records the

track parameters in a separate measuring run.

Then an electronic compensation is performed using

the computer. Reference points such as bridges or

level crossings are recording by pressing the functionkeys during the measuring run.

ALC automatic guiding computer

The ALC automatic guiding computer is an industrial

computer, specially adapted and built by Plasser &

Theurer, with a colour monitor and a keyboard

with touch pad. The installed Flashcard (hard disk),

diskette and ZIP drive enable the extensive storage of

geometry data. A CD-Rom drive is also installed.

A high level of operating comfort is assured by the useof the Windows user interface. Track geometry data

can be displayed in spreadsheet or graphic form.

The machines Duomatic 08-32 and Plasser 08-16 can

be fitted alternatively with one of the two systems.

GVA 97 automatic geometry value adjustment

The GVA 97 is an industrial computer with an 8 MB

Flashcard (hard disk) to store the track geometry data,

a keyboard with touch pad and a colour monitor.

Like the ALC, operation is possible with known and

unknown target geometry.

8 Processor control

All work sequences and hydraulic processes are

controlled and monitored by a microprocessor.

The entire electronic system is built in modular design.

The program control contains a measuring and

monitoring system that enables a fast check of all

control functions.
