THE SILENT TAMPING BANK

A NEW TAMPING CULTURE

THE WHISPER-QUIET TAMPING DRIVE THAT ONLY VIBRATES DURING PENETRATION AND COMPACTION

LOW MAINTENANCE COSTS AND QUICK AMORTISATION

The full hydraulic tamping drive makes rotating parts like eccentric shaft, roller bearings, piston rods, hydraulic motor, fly wheel and tamping flaps obsolete. Additionally, the tamping drive only vibrates during insertion and compaction of the ballast – the rest of the tamping cycle it stands still.

SIGNIFICANT REDUCTION OF NOISE AND DUST

As the tamping drive only vibrates during penetration and compaction a reduction of continuous noise emission more than 7 dBA and a reduction of respirable dust emission of more than 50% is achieved. The full hydraulic tamping drive is a game changer in today railway industry.

INTELLIGENT PENETRATION ASSISTANT

During insertion into the ballast the amplitude and frequency of the tamping drive are variable and electronically controlled. This function was developed for hard ballast bed conditions to reduce the penetration force and related material stress of the tamping machine.

S7 AUTOMATIC TAMPING FOR OPTIMUM COMPACTION

The hydraulic squeezing cylinders are equipped with integrated position sensors and pressure transducers which individually stop squeezing in S7 automatic tamping mode as soon as the optimum compaction force is reached. The optimum compaction of ballast reduces the track geometry deterioration rate.

BALLAST BED ANALYSIS WITH SYSTEM7 INFRASTRUCTURE MANAGEMENT WEB PLATFORM "INFRAME"

Each individual tamping drive is controlled independently and records the data of the achieved ballast compaction, the ballast bed hardness as well as the squeezing path. The quality number of the ballast bed is derived from this. Tamping data is uploaded to the web platform “INFRAME” were the tamping job is visible on a map with related GPS coordinates and an image of each sleeper surrounding.

THE S7 CONVERSION KITIt's time to upgrade your existing tamping machine

The tamping drive conversion kit is available for most conventional tamping banks and offers the advantages of a full hydraulic tamping bank incl. S7 automatic tamping mode and ballast bed analysis.

The following video shows an example of the System7 conversion kit, that has been fitted into a tamping machine of Plasser & Theurer.

A TROUBLE-FREE INSTALLATION

During the conversion, the rotating eccentric drive is removed and replaced by the full hydraulic tamping drive. After adaptation of the hydraulic supply the provided electronic control system gets installed.

SAVE LIFE CYCLE COSTS NOW

Maintenance costs get significantly reduced by less wear parts, less deterioration due to non-vibrating periods in the upper position (up to 70% less vibration each tamping cycle) and quick and easy maintenance even at construction site reduce LCC significantly.

USE YOUR EXISTING MACHINE APPROVALS

The modifications do not interfere with any approval requirements for the transport of railway vehicles by railway companies. Work authorisation remains unchanged: Tamping frequency and tamping amplitude whilst compacting stay the same as before conversion.
