4.3 Description of function
4.3.1 The vibration required for compaction is produced by the exciter (13)
which is firmly joined to the lower mass (5). This exciter (13) is
designed as a central vibrator with aligned vibrations. Such a principle
permits the direction of vibration to be changed by turning the eccentric
weights (15). In this way an infinitely variable transition between
vibration in forward motion , at standstill and in reverse motion is
possible. This process is hydraulically controlled with the operating
control handle (6) on the centre pole head (7).
4.3.2 The drive engine (1) anchored to the upper mass (4) drives the exciter
(13). The torque is transmitted by means of a friction connection
through the centrifugal clutch (11) and the exciter V-belt (12).
4.3.3 The centrifugal clutch (11) interrupts flow of power to the exciter (13)
at low engine speed and thus permits perfect idling of the drive engine
(1).
