3.19 Driving with dynamic compaction system
WARNING
Reduced road adhesion!
Serious injuries or death through the machine tipping over because of
reduced ground adhesion.
■
Never switch on the dynamic compaction system when traveling
across a slope or on hard ground.
WARNING
Explosion!
Severe injury or death by gas explosion.
■
Before switching on vibration, make certain that no gas line is
buried in the ground you will be working on.
NOTICE
Vertical oscillations caused by vibration!
Collapse or damage at buildings or on lines laid in the underground.
■
Do not switch on vibration system near buildings!
■
Prior to switching on the vibration function, it must be ensured that
there are no lines laid in the underground in the vibration area.
Vibration
In the vibration mode the roller drum is shifted to vertical oscillations.
These hammering impacts produce a manifold increase in the
compaction force of the machine.
Effect on the environment:
Vibration oscillations can spread in the ground over a wide area. They
are generated in circles around the roller drum and effect also the deeper
ground. This may cause a damage to buildings or pipe systems under the
machine.
Amplitudes/frequency:
The vibration system uses an amplitude. The frequency depends on the
preselected motor speed.
Oscillation
In the oscillation mode the roller drum is shifted to tangential oscillations.
The compression of the material to be compacted is conducted by flexing
movements.
Effect on the environment:
Oscillation vibrations are developed predominantly on the surface of the
ground and spread only in front of the roller drum and on its rear. Thus
the damaging force is reduced considerably.
Amplitudes/frequency:
Oscillation uses a tangential amplitude. The frequency depends on the
preselected motor speed.
