Dynapac says that its new fifth generation CA single drum vibratory rollers, the CA5000, CA6000 and CA6500, offer performance upgrades over other machines. These machines have transverse-mounted engines that improve serviceability as well as optimised amplitude to boost compaction performance. A novel Active Bouncing Control is said to prevent damage to the machines as well over-compaction. High comfort cabs, good manoeuvrability and reduced noise levels and fuel consumption all help to make these machines
