Atlas Copco’s upgraded soil rollers — the Tier 4 Interim CA2500 and CA3500 — save contractors on fuel costs thanks to patented Efficiency Eccentrics as well as ECO Mode systems. The two rollers enhance productivity with easy maintenance, ergonomic operating stations and high compaction quality. The Efficiency Eccentrics system features eccentric weights positioned toward the right of the axle, which reduces the amount of weight that counteracts the soil roller’s movement at start-up. This reduces energy consumption at start-up by 50 per cent, which also reduces fuel consumption. The low power requirement makes it possible to reduce the roller’s engine size without sacrificing compaction performance.
