| 摘要： | The rollers retain the ability to work in-line or off-set configurations of previous models. This allows compaction against kerbs and other obstructions, while boosting productivity in open spaces.The new double drum rollers are the ARX 12-2, ARX 16-2 and ARX 20-2. Also new is a combination version, the ARX 16-2C, which has a steel drum in front and pneumatic tyres in the rear for higher traction and improved sealing of surfaces.The rollers are powered by Kubota engines that meet Stage Ⅴ and Tier 4 Final emissions standards. A new vibratory circuit setting delivers increase vibratory frequencies that allow faster compaction.The firm says that the new setting enables vibratory frequencies to increase by 3% at low frequency and 6% at high frequency. Meanwhile, improved impact spacing also optimises compaction quality. |
