Tamping machines in compact design:  successful for over 25 years Plasser & Theurer built the first two-axled tamping machines at the start of the 1950’s 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 the tamping 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.

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 For example, the complex design of the front reference point for the levelling and lining chords has been replaced by a fixed positioning; the required correction values are sent to the computer electronically.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 sighting device, multi-channel recorder, air-conditioning units for work and driving cabin. This concept has proven reliable in countless operations.

 For efficient and economical track   maintenance

 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 machine 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 nonsynchronous 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.

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.

The following models are available:

 5 Driver’s cabin

Duomatic 08-32: two two-sleeper tamping units with a total of 32 tamping tines for tamping two sleepers per tamping cycle.

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.

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.

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.

 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

7 GVA 97 and ALC Both 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 of work 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 machine’s 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 function keys 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 use of the Windows user interface. Track geometry data can be displayed in spreadsheet or graphic form.

 Automatic guiding computer ALC

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. View of the working area 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.
