  • Videos

This paver utilises a technologically advanced paver control system that features a variety of automated functions. The system enables productivity, quality and cost-saving efficiency. The AFT 400-3 is productive when space is open, but can negotiate curves and tighter spaces, too. The tracks provide grip, particularly helpful on steep grades. The material feeding system provides consistent mix flow.

MATERIAL FEEDING SYSTEM

Material Conveyor
An efficient conveyor system ensures material flows consistently from the hopper, so productivity and quality goals can be achieved.

  • Tunnel shaped to optimise flow and limit segregation
  • Reversible twin conveyor system for smooth material flow
  • Individual front tensioner
  • Proportional speed control with paddle sensor system
  • Wide tunnel
  • Standard and high-capacity options with twice the number of conveyor bars for improved material flow
Auger System
Consistent auger distribution of material across the screed is essential to placing a quality mat with minimal segregation.

  • Proportional speed control by sonic sensors
  • Reversible and independently driven left and right augers
  • Hydraulic height adjustment of 250 mm, even while paving
  • Torque to handle diameters from 380–500 mm
  • Improved central drive system with slim gearbox (15 cm)
  • Small outer bearings that minimise segregation – even with throughput of 1100 tonnes per hour
  • Auger and auger tunnel easily extended to fit wider working widths
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. An optional hydraulical front flap reduces spilling and improves the emptying process, ultimately resulting in less manual work.

  • Low dumping height
  • Separately controlled wings with solid rubber flaps
  • Rounded corners to prevent cold material from sticking
SAFE Impact system
Ammann Premium Tracked Pavers offer the Safe Impact System – a hydraulic anti-shock push roller that avoids surface marks caused by truck docking. The system also extends docking length, providing flexibility to work with varied truck models.

 
Truck Assist (optional)
This system improves the communication between the paver and the truck driver. It also minimises bumps and spills that can negatively impact paving quality.

  • Allows easy and safe truck positioning
  • Simplifies the communication between the paver operator and the truck driver
  • Communicates via LED bars to provide an alternative to the use of a signal horn
Set Assist (optional)
This intelligent system saves the position of the auger and the screed before relocating the paver.

  • A single push of a button on the operator panel lifts the hydraulic front flap, auger and screed – and reverses the conveyor slightly
  • When the paver arrives at the next location, a single push of a button returns the system to its original position
  • This user-friendly system can be programmed to predetermined settings

Operator Platform

PaveManager 2.0
The automated paving system constantly monitors the process and provides feedback to operators. It also controls many key functions for precise results.

  • Features a CAN-based control system
  • Automates functions such as paving parameters, memory, and crown and slope settings
  • Provides constant feedback to operator
  • Offers adjustments from the operator dashboard or through the screed remote control
  • Screed remotes recognise all MOBA leveling equipment and can be used on either side of the paver
  • Both dashboard and remote controls offer color displays and intuitive menus and functions
  • Display symbols and images are easy to understand
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

Engines
Deutz 54 kW 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 Tier 3 or Tier 4 standards.

  • Insulated engine compartment for sound levels below 104 dB
  • Hydraulically driven cooling system
  • 10 hours of fuel tank autonomy
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 IIIB / 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
