2.9 HANDLING WITH PACKING MATERIAL
There is an "Agreement of Complex Services“ made with the EKO-KOM company, either by ENARCO S.A.
or by suppliers of packing material.
2.10 SPECIAL CONDITIONS OF OPERATION
2.10.1 Operations at low ambient temperature
Compaction at temperature below freezing is highly dependent on water content in the soil to be compacted.
Under such conditions, soil becomes harder and more difficult to compact. It is possible to compact dry
materials or rapidly compact fresh soil, before it gets frozen.
2.10.2 Operation at high altitudes
With increasing altitude, engine power decreases due to changed oxygen content. Within certain extent, it
is possible to improve the engine power by installing different main nozzle and by adjusting the. carburetor
(gasoline engines) or by adjusting the injection system (diesel engines). Should the machine be operated
in high altitudes (above 1500 m above sea level), contact the engine manufacturer to carry out the
adjustments.
In case that you intent to operate the machine in high altitudes in the time of purchase, consult the
manufacturer.
2.10.3 Operations in dusty environment
In case that the machine is operated in extremely dusty environment, it is recommended to shorten the service
intervals for cleaning or replacement of the air filter.
Clean the machine from dust regularly.
3 TECHNICAL DESCRIPTION
Reversible vibrator plates are designated for compaction of all sorts of soil, for compaction of trenches and
surfaces as well as - in the last resort - for compaction of asphalt surfaces.
Centrifugal force of the vibrator has been optimized depending on the machine weight and size of the ground
plate; therefore, high compaction effect has been reached.
Vibratory plates of the VDR line are fitted with directed vibrator. By fluently shifting mutual position of the
eccentric flyweights, the resultant force is changing its direction and thus the plate speed can be fluently
controlled forwards, backwards or the plate may vibrate at a spot. The working part is the ground plate, on
which the vibrator is mounted. The engine base plate is resiliently mounted to the ground plate.
