Caterpillar's AP555E wheeled paver features its Mobil-trac undercarriage that combines the flotation and traction advantages of a crawler suspension with the mobility and ride quality of a wheel-type paver. The 97×16-inch footprint offers uniform weight distribution over the entire length of the belt. Bomag's BF6615 has a turbocharged, water-cooled engine that delivers consistent power at all altitudes. The engine's ECOMODE feature saves fuel and reduces noise by automatically lowering rpm during stops and pauses, while the load-sensing hydraulic system lowers fuel costs by delivering power only when needed. The new UNIMAT 2 full-width floating screed is electrically heated.
