AFT 400-2

  • Photos

This highly maneouvrable, tracked paver is ideal for work in municipalities. It is able to be productive when working in open areas, but can negotiate curves and tighter spaces, too. The tracks provide grip, which is particularly helpful on steep grades. The material feeding system provides consistency that enables quality. The paver is small enough that it can be transported by truck.

Material Feeding System

Material Conveyor

  • A quality conveyor system enables consistent material flow from the hopper to auger and screed, ensuring high productivity and that quality targets can be achieved.
  • Independent conveyor belts with a total width of 700 mm
  • Individual front tensioning system
  • Proportional speed control
Auger System
Consistent distribution of material across the full screed width is a key for Ammann City Class pavers. The slim auger box and the large auger size reduce possible segregation to a minumum and enable the machines to place a quality mat.

  • 320 mm auger diameter
  • Independent, reversible augers
  • Proportional speed control
  • Mechanical height adjustment of 200 mm
The Hopper
The hoppers of the Ammann City pavers ideally suit the machine size, giving it large capacities while maintaining flexibility and compact dimensions needed for its application in innercity areas.

  • 10.5 t hopper capacity
  • Low dumping height of 500 mm
  • Optional safe impact push rollers
  • Optional hydraulic front flaps

 

Operator Platform

Conventional Control (AFT/AFW 400-2)
Conventional control utilises toggle switches and is simple to learn and implement.

  • Easy and intuitive operation
  • Conveniently located toggle switches
  • Easy-to-learn electric system with simple maintenance
  • All material-related functions in manual or automatic mode
Operator Platform
A comfortable work environment is also a safe and productive work environment, too. The City Paver operator platform optimises visibility and ensures all key controls are easily accessible. The operating system is nearly identical to those of other Ammann pavers, making it easy and safe for operators to switch between models.

  • Clear sight lines to all components
  • Slidable and tiltable working stations
  • Optional windshield

Engine, undercarriage key components

Engines
Deutz engines are the power behind the Ammann AFT 400-2, AFW 400-2, AFT 400-3 and AFW 400-3 Asphalt Pavers. Highly advanced e-hydraulic controls provide efficiency. The engines are available to meet Stage IIIA or Stage V standards.

  • Insulated engine compartment for sound levels below 104 dB
  • Hydraulically driven cooling system
  • 10 hours of fuel tank autonomy (73 l)
Stage IIIA / T3 Engine
  • Powerful and quiet
  • Improved fuel efficiency and cold-start performance
  • New cylinder block with deep crankcase for higher power and torque
Stage V / T4f Engine
  • Superior lifetime value with higher fuel efficiency
  • Reduced maintenance and longer service intervals
  • Improved common-rail technology for enhanced performance
  • No regeneration process is needed
Track System
Tracks with high pulling forces help Ammann City Pavers overcome the varied terrain that often is encountered in cities. The pavers provide manoeuvrability, too.

  • Paving speed up to 25 metres per minute
  • Travel speed up to 4 km per hour
  • 2.09 metre axle track
  • 260 mm track pads

Highest paving quality

  • Dual-tube extension provides best-in-class stability, even at max. paving widths
  • Slim end gates enable paving close to curbs and walls
  • Easy adjustment of the angle of attack by Flexi Lever
  • Extension boxes utilise patented quick-coupling system that reduces setup time
  • Rubber mounted foot steps eliminate wear and reduces noise
  • Low profile walk plates enable great view into auger compartment
  • Side shields utilise integrated wiring
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
