CONSTRUCTION EQUIPMENT MARKET WATCH

摘要

The CR552 rubber-tired asphalt paver has been upgraded to Tier 4-Final with a 260-horsepower Cummins engine. Cooling air is drawn from above the hood, rather than at ground level, for cleaner air quality. It exits primarily through the front grill, resulting in a pressurized engine compartment that reduces debris infiltration. The machine can pave to 30 feet wide at depths reaching 12 inches. The paver has a heavy-duty rear drive motor for "track-like" traction, according to the company. Hopper capacities up to 27 tons allow paving rates more than 800 tph. Both operator seats pivot beyond the side for direct visibility to the tires, and the console pivots to line up with the seat. The generator powering electric screeds has been moved, lowering sound levels to the operator.
