This large tracked paver features powerful Tier 3 engines and intuitive conventional electronics that are easy to learn. A variety of screed options help ensure quality and pre-compaction goals are met. Toggle switches provide the control – and are easy to maintain, too. The impact of dump trucks is lessened through a low hopper dump height and oscillating push rollers.

Material Feeding System

Material Conveyor
The twin conveyor system ensures material flows consistently from the hopper, so productivity and quality goals can be achieved.
Wide material tunnel to optimise flow and limit segregation

  • Twin conveyor system
  • High-capacity kit for thick and wide layers (AFT 700-2)
  • Individual front tensioner
  • Proportional speed control
Auger System
Consistent auger distribution of material across the screed is essential to placing a quality mat with minimal segregation.

  • Left and right augers reversible with independent drives
  • High torque
  • Proportional speed control by sonic sensors
  • 380 mm flight size
  • Mechanical height adjustment of 250 mm
  • Slim gearbox to minimise segregation
The hopper
The hopper is designed to reduce spilling during connections between the paver and the lorries. It is also designed to maximise flow and minimise segregation.
The result: improved quality in the form of smoother mats.

  • Low dumping height
  • Separately controlled wings with solid rubber flaps
  • Rounded corners to prevent cold material sticking

Engine, undercarriage key components

Engine
A Cummins QSB 6.7 litre, water-cooled engine is the power inside the Ammann AFT 600-2, AFW 600-2, AFT 700-2 and AFW 700-2. The engine drives an efficient hydraulic system, with power transfer through a split gearbox.

  • Tier 3 / Stage IIIA emissions standards
  • High torque
  • Fuel efficiency
  • High fuel tank capacity
  • Efficient cooling system to eliminates the risk of overheating the engine and the hydraulic system
Tracked pavers
Tracks help Ammann Large Pavers with conventional controls overcome challenging terrain and provide the grip needed when paving large widths. The tracks are powered by hydraulic motors with planetary gears for high torque, assuring great traction forces. Track motors feature an automatic flow control system to maintain a straight drive.

  • 320 mm track pads for ground contact and grip
  • Pads designed for paving applications with thick rubber for long life
  • Improved manoeuvrability in curves through the high number of rollers inside the tracks
  • Independent drive on each track for 360º turns
  • Low-profile tracks with hydraulic tensioning and optimised suspension for more traction and rigidity

SCREEDS

4-Tube principle
The high stability of the Ammann screeds is due to the 4-Tube principle design. These four tubes allow wide working widths without the need of any supporting rods. This makes the setup of the screed easier and saves time when preparing the paver for large working widths.Screed heating
Ammann screeds feature gas (LPG) or electric heating systems, leaving the choice of the preferred system up to the customer. Electric heated screeds feature high quality insulations and powerful generator to reduce heat-up times. Well designed heating coils for the bottom plates and tampers grant a well distributed heat over the full length of the screed. Gas heated screeds feature a fast heat-up time that reach target temperatures quickly.
Eccentric Flexilever

  • Quickly and conveniently changes the angle of attack
  • Offers visual confirmation of the angle of attack
  • Adjustment made easy with one crank on each screed side
Simple side shield control

  • Height and angle adjusted with a single crank
  • Can be adjusted from behind the screed, keeping operators away from traffic
  • Integrated wiring
