4. Description
4.1 Applications
The vibratory plate is excellently suited for the compaction of most
types of soils, including semi-cohesive soils, both in trench and in
surface compaction operations, as well as for the vibrating of heavy
interlocking concrete blocks or paving stones.
4.2 Dimensions
4.3 Max. admissible inclination

Description
T01042GB 12
4.4 Description of function
The vibration needed for the soil compaction is generated in the exciter
(9). The exciter is tightly bolted to the lower mass (8). It has been
designed as a central exciter, therefore allowing - by ways of a relative
rotationbetween the excentric weights (1) - the rotation of the direction
of the vibrations. Thanks to this technique, it becomes possible to
changeoverfromforwardtraveltoarightorleftturnortoreversetravel
of the vibratory plate while during the compaction operation. This
process is controlled by means of a set of electro-hydraulic switching
valves.
The drive engine (12) anchored to the upper mass (7) drives the
exciter (9). The torque is transmitted by means of a friction connection
through the centrifugal clutch (4) and the exciter V-belt (10).
The centrifugal clutch interrupts flow of power to the exciter at low
engine speeds and thus permits perfect idling of the drive engine.

Description
T01042GB 13
The automatic V-belt pulley (3) combined with the centrifugal clutch
ensures optimum tension of the exciter V-belt during operation and
relief of the tension of the exciter V-belt when the machine is being
relocated or transported.
Moreover, the automatic V-belt pulley (3) automatically adapts to the
V-belt flanks in line with the wear and thus makes the entire drive from
the engine (12) to the exciter (9) maintenance-free.
The upper (7) and lower (8) masses are connected to each other by 4
vibration-damping shock mounts (11). This damping system prevents
the very high frequencies from being transmitted to the upper mass. As
a result the functionability of the drive engine is retained in spite of the
high compaction performance.
The drive engine works on the diesel principle; it is started electrically
by a pinion starter (5), draws in the combustion air through an air filter,
dry (2) and is air-colled.
The machine is equipped with a fully electronic anti-restart delay
module that prevents any malfunction with consequential damages.
Always start and stop the machine from the remote control panel. To
facilitate the starting procedure (at very low temperatures) the drive
engine has an automatic decompression mechanism.

Description
T01042GB 14
4.5 Infrared remote control
Always keep operating elements dry, clean and free of oil or grease.
Above all do not cover receiver or transmitter (remote control) under
any circumstances.

4.7 Changing the transmission channel
You can set the sending channel in the sender and on the decoder on
the switch (v).
To change the channel on the sender, open the sender and move it to
one of the three possible positions..
The decoder must be set to the same channel as the transmitter.
After setting the desired channel, check the setting by switching on the
vibratory plate and the sender (see ”Activating the Machine”) – if the
channel selections match, the LED ring (b) on the receiver eye will
begin blinking.
4.8 Safety functions
To enhance the safety of the operator, the machine is equipped with a
function that automatically ceases all dangerous movements as soon
as the operator comes too close to the moving machine. All functions
are reactivated when the operator leaves the safety zone.

5. Transport to work site /Recommendations on compaction
5.1 Transport to work site
Conditions:
∗To transport the vibration plate, only use suitable lifting equipment with
a minimum load-bearing capacity of 700 kg.
∗Always switch off engine before transporting the machine!
∗Only attach suitable tackle at the central lifting point (13) provided.
∗During transport on the loading area of a vehicle, tie down the vibraion
plate using the lugs (14).
Hote: Also overve the regulations in “safety instructions“.

Transport to work site /Recommendations on compaction
T01043GB 18
5.2 Recommendations on compaction
5.2.1 Ground conditions
The max. compaction depth depends on several factors relating to the
ground condition, such as moisture, grain distribution etc,
it is therefore not possible to specify exact values.
Recommendation: In each case determine the max. compaction
depth with compaction tests and soil samples.
5.2.1 Compaction on slopes
The following points are to be observed when compacting on sloped
surfaces (slopes, embankments):
∗Only approach gradients from the bottom (a gradient which can be
easily overcome upwards, can also be compacted downwards without
any risk).
∗The operator must never stand in the direction of descent (see chapter
“safety instructions“).
∗The max. gradient of 15omust not be exceeded.
If this gradient were exceeded, this would result in a failure of the
engine lubrication system and thus inevitably lead to a breakdown of
important engine components.
