Brief description
The vibratory plate is a machine that compacts soil.
The vibration required for compaction is produced by the exciter firmly connected
to the base plate. This exciter is designed as a central vibrator with aligned vibra-
tions. Such a principle permits a change in the oscillation direction by turning the
eccentric weights.
Thus a continuous transition between compaction during advance travel, when
standing still and in reverse travel is possible. This process is controlled hydrau-
lically with the control handle on the centre pole head.
The drive motor secured to the upper mass drives the exciter. The torque is firmly
transmitted via the centrifugal clutch and the exciter V-belt.
The centrifugal clutch interrupts at low engine speed the flow of power to the ex-
citer and thus permits flawless idling of the drive motor.
The automatic V-belt pulley combined with the centrifugal clutch ensures during
operation an optimum voltage of the exciter V-belt and relief of the exciter V-belt
when moving or when transporting the machine.
In addition, the automatic V-belt pulley automatically adjusts itself according to
the wear on the V-belt edges and thus makes the entire drive from the engine to
the exciter maintenance-free.
The speed of the drive motor can be varied continuously, operated remotely by
the throttle control lever and locked in the idle setting. Upper mass and base
plate are connected to each other by 4 vibration rubber mounts. This damping
prevents transmission of very high frequencies to the upper mass. Thus the func-
tionality of the drive motor is maintained despite a high compaction performance.
