Abstract
A hand-operated forward-reverse vibrating plate compactor which includes a vibrating assembly having two counter-rotating eccentrics. The vibrational force generated by the eccentrics is directional and the forward and reverse motion of the vibrating plate compactor is achieved by changing the phase position of the eccentrics relative to each other. This change in the phase position is accomplished smoothly by means of a hydraulic servo control system which permits a continuously variable adjustment of the speed and intensity of the vibration of the vibrating plate compactor to be made.
