DESCRIPTION
Description of function
The vibration required for compaction is produced by the exciter (4) which is firmly joinded to the lower mass
(3). This exciter (4) is designed as a central vibrator with single-plane vibrations. Such a principle permits the
direction of vibration to be changed by turning the eccentric weights (11). In this way an infinitely variable tran-
sition between vibration in forward motion, on the spot and in reverse motion is possible. This process is hy-
draulically controlled with the operating control handle (6) on the centre pole head (7).
The drive engine (1) is anchored to the upper mass (2) and drives the exciter (4). The torque is transmitted by
means of a friction connection through the centrifugal clutch (8) and the exciter V-belt (9).
The centrifugal clutch (8) interrupts flow of power to the exciter (4) at low engine speeds and thus permits per-
fect idling of the drive engine (1). The speed of the drive engine (1) can be infinitely varied by way of the throttle
control lever (5).
The upper (2) and lower (3) masses are connected to each other by 4 vibration-damping shock mounts (10).
This damping system prevents the very high frequencies from being transmitted to the upper mass (2). As a
result the funcionability of the drive engine (1) is retained in spite of the high compaction performance.
The drive engine (1), is started by way of a rewind starter.
