New Auger, Tunnel Systems for F1000 Pavers
Atlas Copco F1000W wheeled and F1000T tracked pavers can be equipped with either a center auger drive system or outboard auger drive system to best fit job site conditions and materials. The pavers also can be equipped with Atlas Copco’s new tunnel extension system.
Atlas Copco’s center drive auger system features a 6-inch-wide chain box — the thinnest in the industry — and 17-inch diameter flights to ensure continuous, uniform material flow and minimize centerline segregation. Center drive is suitable in all paving applications and works best for areas where the width of the pavement is frequently changing such as highways, city streets and large parking lots as well as high speed paving applications.
Atlas Copco’s outboard auger drive system is ideal for paving wide roads and for normal speed paving applications. The drive box for the left and right auger are positioned at the outer edges which helps minimize center line segregation and ensure high mat quality and texture.
Dynapac’s exclusive auger-conveyor feed-control system ensures a continuous material flow. The system uses four ultrasonic sensors that measure paving material and automatically adjust conveyors and augers to optimize material flow. The system eliminates segregation and delivers a constant head of material and the smooth flow needed to produce high-quality mats.
The 10-foot pavers can also include a hydraulic tunnel extension system along with the center drive auger system. The 22-inch wide hydraulic tunnel extension will automatically retract when screed extensions begin to retract to prevent collision. The hydraulic tunnel reduces excess head of material in the tunnel area and prevents asphalt from entering into track components.
Mechanics can access all hydraulic system and engine components easily by opening the paver’s steel access doors that feature gas springs. The gas springs make it easy for mechanics to open the service doors and securely holds the doors open during repairs. In addition, the engine compartment’s configuration allows mechanics to remove internal components independent of others. For example, a mechanic can remove the diesel particulate filter without taking out other components first.
The material flows through the Carlson front- or rear-mounted screed to construct flawless mats. A tractor-mounted 34-kW generator heats the screed’s full working width, which is as wide as 28 feet with the Carlson EZ R-2 screed. The front extension screed is ideal for paving parking lots, county roads and city streets because contractors can change its width quickly to suit to the project’s demands. The rear extension screed extends to 28 feet wide for use on large paving projects, including highways, interstates and airports.
