Atlas Copco has introduced a new 8-foot tracked paver to complement its existing 10-foot highway class paver range. The Dynapac F800T paver is designed specifically for North American customers and meets Tier 4 Final emission regulations.
Smooth material flow
The F800T has a working width of 8 feet to 19 feet and paves to 12 inches thick. Innovative features such as a patented safe-impact push-roller system, chamfered hoppers, dual bar feed conveyors and the world’s thinnest auger chain box ensure a smooth and continuous flow of material for best mat quality.
The Dynapac F800 series’ patented safe-impact push-roller option ensures that shock from bumping the truck is not transmitted to the screed.
The material hopper can hold up to 13.5 tons of asphalt, matching the largest material hoppers available in this class. Chamfered corners on the hopper discourage asphalt from sticking at the corners and allow easy cleaning at the end of paving shift. Dynapac F800 series pavers can also be equipped with hydraulically operated aprons. The aprons prevent spillage at the front and provide easy dumping of residual asphalt back into the hopper.
The Dynapac F800 paver’s independently controlled, dual-bar feed conveyor system with large auger flights ensures continuous flow of material. The 17-inch-diameter auger flights are the largest in the industry and are attached to the world’s thinnest center chain box at just 6 inches wide, eliminating centerline segregation.
Both auger and conveyor speed control are achieved through an integrated feed control system using four ultrasonic sensors. The integrated hydraulic tunnel option eliminates material spillage toward the track and provides optimum material head.
Power-packed performance
The Atlas Copco Dynapac F800T tracked paver’s six-cylinder, 173 hp Cummins QSB 6.7 Tier 4 Final engine provides ample power for a wide variety of jobsite conditions. The six-cylinder engine means less strain on engine components and increased longevity. The ECO mode setting further reduces fuel consumption during paving operations.
Hydraulic components on the Dynapac F800T match the F1000 10-foot paver range, which ensures availability of parts. The oversized hydraulic components also generate less heat, which reduces fatigue loading and increases component life.
An efficient cross-flow cooling system with a hydraulically-driven, temperature-dependent variable speed fan significantly reduces the noise level. A variable speed fan uses less energy, meaning more power for paving applications even in extremely hot working conditions. The bypass valve on the hydraulic oil cooler quickly brings the machine temperature to operating parameters, reducing idle time in cold working conditions.
