4.3 Functional description
The vibration required for compaction is generated by the exciter (5)
that is permanently attached to the base plate (4). The exciter is
designed as a central vibrator with directional vibrations. This principle
allows you to change the direction of vibration by simply turning the
eccentric weights (13). This makes a gradual transition possible
between the vibration states: moving forward, moving in reverse and
in a stationary position. This procedure is hydraulically controlled with
the control handle (7) on the guide handle head (8).
When hydraulic oil is lost the machine operates in the reverse direction
(danger of crushing).
The drive motor (1) attached to the upper mass (3) powers the exciter
(5). The torque is transferred non-positively by the centrifugal clutch (9)
and the exciter V-belt (10).
When the motor speed is low, the centrifugal clutch (9) interrupts the
power flow to the exciter (5) which allows the drive motor (1) to idle
properly. The speed of the drive motor can be continuously varied
using the throttle regulation lever (6).
