Rail – Construction and Maintenance

Hydraulic Tamping – A New Era of Tamping

System 7 is revolutionising rail infrastructure with the introduction of a new fully hydraulic tamping system. Characterised by a fully hydraulic workhead and specially designed cylinder and valve assembly, the future of tamping is upon us.

  • Reduced noise emissions
  • Reduced maintenance costs
  • More efficient and accurate tamping work
  • Less wear on the workheads
  • Ballast quality reporting
  • Longer equipment lifespan
  • Open source parts
  • Reduced repair time

Hydraulic Work-Head

The new system replaces the rotating parts and bearing assemblies of conventional tamping drives with a fully hydraulic work-head.

By eliminating the large amount of moving parts associated with eccentric drives, the new hydraulic system results in:

  • Improved machine reliability – reduced wear
  • Reduced maintenance costs – no rotating parts to replace

The new system features continually adjustable frequencies during the tamping cycle to maintain the best possible consolidation for every sleeper.

Pressure Controlled Tamping

System 7’s tamping drive continually measures the hardness of the ballast and adjusts the frequency to ensure optimum insertion and reduced wear on the machine frame.

The system measures the compaction under each sleeper and will stop tamping when the required compaction has been achieved which in turn eliminates over tamping and ensures optimum compaction under each sleeper.

Ballast Quality Reporting

Using our unique technology, the system continually measures the hardness of the ballast as the tamper inserts its tines. It analyses the data from the workhead and provides information on the quality of the ballast.

This unique capability allows the early identification of ballast issues and proactive maintenance management and planning. If coupled with RaVeM, ballast quality information can be sent automatically to relevant staff.

Specially Designed Cylinder And Valve Assembly

The replacement of the traditional squeeze cylinders with a specially designed cylinder and valve assembly creates the ability to automatically adjust:

  • Squeeze pressure applied to ballast
  • Frequency and amplitude of vibration
  • Position of every tine at any point in the cycle
  • Consistent compaction achieved under each sleeper or bearer

Significant Noise Reduction

The new system results in significantly reduced noise generation during the tamping cycle and ballast compaction compared to traditional eccentric drives systems.

The hydraulic work-head contains a tamping drive that only vibrates during penetration, resulting in a massive reduction of noise emission up to 7dBA which is a huge win for the community living adjacent to the railways.

Shift Report Generation

An inbuilt operation in the new system is the shift report generation allowing:

  • Detailed data on the hardness of the ballast
  • Production of a ballast quality report
  • Identification of any areas of substandard ballast
  • Planning for future maintenance.

The RaVeM system can be linked to the shift report system to assist in timely maintenance planning. Automatic shift reports can be generated on predetermined data such as ballast quality so when a critical area is encountered, rail managers are informed instantly via automatic alert and maintenance can be planned immediately.

Trouble Free Installation Options

The new system is available for installation as a stand-alone tamping drive or complete work-head option. Both systems can be retrofitted to existing tamping machines to alleviate the need for large upfront capital outlays.


The RaVeM System is able to provide valuable information about rail material usage and actual load capacity for accurate tamping monitoring.

It can be utilised on railroad track machines to monitor work output such as distance tamped and cleaned. For railway wagons, service history and operational performance data such as load capacity and temperature can be recorded and a work report generated from the data.

Oil Condition Monitoring For Ultimate Performance

The System 7 Oil Quality System is the latest highly flexible and cost effective technology in oil condition monitoring, delivering real time monitoring of the condition of any lubricating oil.

The Oil Quality System is a condition-based monitoring solution that is over 60 times more sensitive to oil contamination that any other sensor on the market.

It provides real time data feedback on the in service condition of your oil, giving you a full 360o view of your oil’s performance.


The sensor continually sends information back to System 7’s online database RaVeM, which contains unique algorithms to interpret the data and identify any potential equipment failures before a catastrophic failure occurs. Equipment patterns can be identified prior to a scheduled service allowing technicians to focus on potential problem areas.

RaVeM will continually track the condition of the oil and calculate the time remaining before an oil change is required. The System 7 Oil Quality System allows you to accurately predict when your next service is next due rather than working on machine hours.

Oil Manager – Good Lubrication for peak performance

Time saved is money saved. Our Oil Manager takes the time-consuming task of unplanned engine oil top-ups off your hands in diesel locomotives and passenger trains. Ensuring optimum engine oil levels means no more diesel engine damage due to insufficient lubrication as our system continually maintains the oil levels.


Not only does our Oil Manager maintain oil levels but it monitors consumption trends and provides trend analysis of your usage. In addition, the Oil Quality System can be fitted to provide real time information on oil quality. Our system can detect contamination levels with an accuracy of 15PPM and can identify a broad spectrum of contaminates from fuel and water to carbon.


Equipped with GPS, GPM, sensors and data logging, System 7’s Fuel Monitor helps to monitor track, underground and road construction machines by measuring the fuel filling level at regular intervals and delivers data pertaining to:

  • Operating modes
  • Status of monitored vehicles
  • Fuel consumption
  • Improper operation of the vehicle
  • Fuel theft
  • Consumption trends
  • GPS location
  • Utilisation and
  • Speed data

It delivers an unprecedented amount of data about your engines so you are informed about the status of your equipment at all times.
