Compaction Width
Eight 13/80 R20 rubber tires provide overall compaction width of 2090 mm (82″) with 25 mm (1″) overlap.
Flexible Ballast
Ballast options include modular and non-modular steel, sand, and water. The 6.5 metric ton (7.1 U.S. ton) modular steel can be easily added or removed through bolt-on side panels. The internal, non-modular steel consists of 6.1 metric tons (6.7 U.S. ton). Also, a 3 cubic meter (793 gal) water-tight chamber with baffled compartments prevent surge, and balance weight.
Oscillating Tires
Oscillating front and rear tires deliver vertical and horizontal forces that reduce air voids, providing surface uniformity. Heat retention covers trap heat to keep the tires warm and prevent pick-up. They can be easily stored when not in use.
Air-on-the-Run
The 13/80 R20 rubber tires can be equipped with the optional air-on-the-run system that enables the operator to quickly adjust tire pressures to increase or decrease static loads for optimal surface quality.
