Dynapac unveils fifth generation of CA single drum vibratory rollers

June 11, 2012 – Dynapac USA has introduced four new models of their
CA-series single drum vibratory rollers. The CA5000, CA5500, CA6000 and CA6500
have been equipped with a number of enhancements over previous models,
including optimized drum amplitude, Automatic Bouncing Control and an overall
design that makes it easier to service the equipment.

June 11, 2012 – Dynapac USA has introduced four new models of their
CA-series single drum vibratory rollers. The CA5000, CA5500, CA6000 and CA6500
have been equipped with a number of enhancements over previous models,
including optimized drum amplitude, Automatic Bouncing Control and an overall
design that makes it easier to service the equipment.

Superior compaction is delivered by the new models
utilizing a drum amplitude of .083 inch (2.1 mm). This increased force allows
rock fill to be compacted in layers almost nine feet thick with rock sizes up
to three feet in diameter. It also requires fewer passes to reach compaction
specifications.

Automatic Bouncing Control measures feedback from the drum
and eliminates drum bouncing, or over compacting.  This new feature improves compaction
performance while extending the useful life of the equipment by eliminating
drum double-jump, which could lead to premature failure of machine components.
The CA6000D model also features a governor to avoid compacting at too high a
speed. 

A full package of design features enhances the
serviceability of all models. The new cross-mounted engine not only offers easy
access for service and maintenance, it also provides weight distribution and
reduces overall machine length. The hydraulic pumps, arranged in line with the
engine, are easily accessed for servicing.

Another key new feature is the ECO mode fuel conservation system that minimizes fuel consumption
as well as carbon dioxide emissions by ensuring that the roller does not
consume more power than needed at any given time. The new models also give
attention to enhanced safety features with Electronic Drive Control, which
provides a quick brake function and a tilt indicator. Dynapac’s anti-spin
traction system ensures consistent on-the-go traction and grade ability.

The combustion air intake is placed on the engine hood
with the outlet running down the sides, thereby keeping the inlet air as clean
as possible. When combined with the ejector exhaust outlet, this placement also
serves to minimize noise levels.

The new CA rollers have static linear loads of 280 pounds
per linear inch (pli) on the CA5000, 310pli on the CA5500, 335pli on the CA6000
and 365pli on the CA6500. All four models are equipped with interim Tier 4
engines from Deutz, and can use a mix of biodiesel and regular diesel fuel.

Optional features on the new rollers include

• Service interval
  alert on instrument panel indicates when a particular service is required
• Sustainability Package: An rpm management system, biodegradable
  fill-for-life hydraulic fluid, 50 hours service kit, electrical engine
  block heater and working lights with LED lamps (CA6000D only).
• Air-conditioned cabs
  with spin-around seat and steering module, offering movement of up to 180
  degrees without stressing neck or body. Spin-around seats are also
  available as a standalone option, without the cab.
• Productivity
  software, including Dynapac CompBase, providing task planning, execution
  and analysis, and CostCtrl web-based software for life-cycle cost control
  and increased machine availability.

The new CA rollers are available in standard models with a
choice of specifications and available options allowing customers to build
their own machines, or choose from a number of pre-defined packages.
