<p>A vibrating plate has a compactor plate with engine and vibration generator and a handle for the operation of the vibrating plate. The shaft and operating members (10 and 11, respectively) of the handle are interconnected by means of spring elements (16) and a spring deflection restricting device (14, 19). According to the invention, the mass of the operating member (11) and the spring stiffness of the spring element (16) are so adapted to one another and to the vibration frequency of the vibrating plate that the relationship of said frequency and the characteristic frequency of the operation member with regard to translational and rotational movements respectively along and about the axis of the operating member and respectively along and about two directions at right angles to the axis and also to one another, is >$(1,3)$2. </p> |
