Abstract
A vibratory compacting roller includes a rotatable compacting roll, and a motor driven vibrator. The vibrator includes a shaft, a movable mass rotatable with the shaft and adjustable transversely thereof, and a position regulator for regulating the position of the mass to provide for a variable amplitude of vibration, the amplitude of vibration of the vibrator being lowest when the center of gravity of the mass is nearest the shaft and greatest when the center of gravity of the mass is farthest from the shaft. The position regulator comprises a spring which automatically positions the eccentric mass to the low amplitude position when the shaft is at rest, whereby minimal start-up torque is imposed upon the motor. A releaseable locking mechanism locks the mass in the low-amplitude position.
