The 47,179-pound Super 2100-3i tracked asphalt paver succeeds the Super 2100-2 and paves widths from 8 feet 4 inches to 42 feet 6 inches. The EcoPlus low-emissions package reduces fuel consumption and noise, the company says. When the paver is stationary while waiting, all hydraulic pumps for traction, conveyors and augers and compacting systems are automatically disengaged after about one minute. The tamper is driven by a variable-displacement pump that delivers exactly the amount of oil needed for the current tamper speed. The speed of the variable-speed fan automatically adjusts in line with engine load and ambient temperature, as well as the temperature of the oil and cooling water.
