Ingersoll Rand released a number of new products at Intermat including new rollers and a new asphalt paver featuring the company''s the new EPMII (electronic paver management) paver control system.

The Alexander DD 95-1 tandem vibrating roller on show (the Alexander DD 85-1 is a smaller version), features the latest electronic control system, but one designed to be easy to learn and use, for efficient and effective compaction.

The company also unveiled its new low-noise tracked Titan 7820 asphalt paver, featuring the EPMII system, and powered by a Tier 3 Deutz Diesel TCD 2013L06 2V engine with an output of 170kW.

The machine has a working width of 2.5m to 5m, and is capable of paving a maximum width of 10m, depending on the screed. With a laydown rate of up to 700tonnes/hr, it has a maximum paving depth of 300mm.

Gary Michel, president of Ingersoll Rand Construction Technologies, said that the company was placing great emphasis on safety and health issues, and the use of electronics such as the EPMII would allow the operator to focus on what was happening outside the cab.

Also, brand new on the stand was the DD-24 double drum vibratory asphalt compactor, which has an operating weight of 2,400kg; a drum width of 200mm; vibration frequency of 55-67Hz, and an amplitude of 0.53mm.

The DD 85-1 weighs 8.75tonnes, while the DD 95-1 has a 9.65tonne roller: both have a drum width of 1,680mm, and are powered by a Deutz BF4M2011 diesel rated at 60kW.

According to the company, the controls are designed to allow the operator to master the rollers very quickly. After a short period of familiarisation, the explicit symbols and the clear layout of the multifunction graphic display make operation simple.

The display is connected by a CAN bus directly to a central control unit, similar to the successful EPM control system (introduced in 1998) on the company''s Titan pavers.

Ingersoll Rand maintains the most important benefit of the electronic control system is the precise steering it facilitates on the new rollers, including precise forward travel, uniform negotiation of bends and controlled offset drum steering.

Also launched at Intermat was the new Ingersoll Rand CompAnalyzer, a versatile digital compaction meter for the company''s Terra Firma range of soil compactors.

Compaction meters are an increasing requirement in construction and road projects. Many clients request contractors use a system to provide full documentation of the compaction process during a project, to ensure that surfaces are uniformly compacted to provide the essential foundation for work later in the project.

The CompAnalyzer records up to 18 adjacent tracks and up to eight passes per track, giving complete compaction measurement coverage.
Depending on how the system is set up, with intervals of 0.25m, 0.5m and 1m possible, it can display the equivalent of up to 350km of compaction runs.

The new EPM II control panel displays the paver-finisher in overview, with control keys positioned on the panel in relation to where their relevant functions take place on the machine. The driver of the paver is thus able to select functions intuitively.

The display is divided into five separate areas, with each area coloured and reduced to the major functions, covering:

＆#8226; Warning and fault symbols.
＆#8226; Fault messages.
＆#8226; A fixed area providing information on engine speed, cooling water level, tamper speed, levelling system, etc.
＆#8226; A changeable area showing the ＆#118alues set by the driver graphically.
＆#8226; Function keys such as plus and minus keys.
