Attorney, Agent or FirmInternational ClassE01C 019/28Foreign Application Priority Data2000-06-01 JPAbstractA vibratory roller R comprises a pair of rolls 5 axially supported at both sides of a body 1 in a cantilevered fashion, a pair of vibration generating devices 6 for vibrating each of the rolls 5, a pair of vibrating motors 7 for driving each of the vibration generating devices 6 and a pair of roll-driving motors 8 for rotating each of the rolls 5. The rolls 5 are connected to each other through the roll-driving motors 8 and by a connecting member 29, and the connecting member 29 is attached to the body 1 through vibration isolating members 30. The vibratory roller R enables a compacting operation with both rolls 5 vibrating simultaneously, and the service life of the vibration isolating members 30 can be extended. | |
