DESCRIPTION
Description of function
The vibration required for compaction is generated via the exciter (6) which is firmly connected to the base plate
(5). The exciter (6) has been designed as a centrally mounted exciter with single plane (directional) oscillations.
This principle allows for the changing over of the direction of the oscillations by changing the relative position
of the eccentric weights (12). Said principle also makes it possible to pass from forward travel to reverse travel
motion.
Forwards Reverse
This procedure is hydraulically controlled by way of the operating control handle (7) situated at the upper end
of the center pole (8) and an electrically operated disable switch (9), which receives a switch signal from a roll
touch switch (10) placed at the center pole head. An oil flow governor valve (15) supplies the steering line with
a partial oil flow.
The exciter (6) is driven by an hydraulic motor (14). The oil flow required for the motor (14) comes from the
pump (13), which in turn is driven by the drive engine (1).
The rpm's of the drive engine (1) can be adjusted by way of the remote throttle lever (16) (normally in the full
throttle position).
The upper mass (11) and the base plate (5) are connected to each other by way of 4 vibration damping shock
mounts (17). The damping effect reduces to a high degree the vibrations being transmitted from the base plate
(5) to the upper mass (11), thereby protecting the engine and simultaneously providing for an easy maneuver-
ability of the machine by the operator.
The twin cylinder drive engine works according to the 4-stroke diesel engine principle, is started electrically by
way of a battery (2) and a gear and pinion starter (3), sucks in combustion air through an oil bath air filter with
an incorporated cyclone pre-filter (4) and is air-cooled.
