The Ammann AFW 500 wheeled asphalt paver is available for most of Southeast Asia and South African market. The machine features a standard paving width of 2.55 to 4.9 m. It can work at widths up to 6.5 m with the use of mechanical extensions.
Powered by a 119-kW Cummins engine, the AFW 500 is effective at placing both binding courses and surface lifts. Its capacity and size make the paver an ideal fit for larger road projects, such as highway applications. The four-cylinder engine is liquid-cooled and meets all Tier 3 emissions standards.
Operation is kept simple with the help of an advanced dashboard and screed control panel created specifically for the AFW 500. The panel is simple to understand, and operators appreciate touches such as illuminated buttons that provide optimal visibility when working at night. Integrated lighting also enhances visibility during night shifts.
The control unit is comprised of multiple individual parts, which facilitate cost-effective replacement. A central 5-in colour display provides the operator with key information regarding the ongoing paving process. The display also enables simple troubleshooting tips and alerts the operator on maintenance needs.
The paver design, sliding seat and dashboard improve visibility during all phases of the paving process. A levelling system of the customer’s choice can be connected to the control unit. The installation plug is pre-mounted and allows for quick connection to the levelling sensors and controls.
A lower discharge height reduces material spillage that can lead to mat defects. The hopper height also matches trucks of varied sizes, increasing fleet utilisation and making it easier to find outside haulers with appropriately sized vehicles.
Material is transported by two independent, reversible chain belt conveyors controlled by paddle micro-switches. Two proportional ultrasonic controls optimise material distribution by regulating flow to the screed.
An optimised auger ensures uniform material distribution, even at wide paving widths. A small auger drive gearbox prevents segregation and cooling of material beneath the drive. Standard e-hydraulic auger height adjustment reduces the risk of segregation and ensures sufficient material beneath the gearbox.
An e-hydraulic device unloads the weight of the screed, thereby enabling an increase in paving depth. This Improves traction by transferring the weight of the screed to the wheels. The raised screed position is maintained when the machine is on standby mode. Moreover, a user-friendly screed control box allows the operator to stay in control and clear layout for easy operation.
