- Fully oscillating bogie wheels, minimizes tow-point movement and
maintain ground pressure
- Automatic belt tensioning ensures performance minimizes wear
- Tread-bar or smooth belts to meet a variety of conditions
• Steel track undercarriage
- Unique oscillating quad-rear bogie provides oscillation for smoother ride,
less tow-point movement ADVISOR DISPLAY
- Automatic track tensioning ensures performance, and reduces wear
• Advanced screed assist
- Provides upward force on the screed, eliminates settling
- Independent settings for standby and pave modes
• Material delivery system
- Independent control of each auger and each conveyor
- Automatic controls ensure precise delivery
- Over-sized components run slower for reduced material segregation and
parts wear
INDEPENDENT MIX DELIVERY
• AS4251C Screed
- 4 ton weight and 40 cm screed plate depth provide stability and reactivity
