Field of application

External vibrators are generally used when space for using an internal vibrator is restricted. External
vibrators are also suitable for attaching to all types of vibratory tables and vibratory stands.
Specific variants of this machine can even be mounted on conveyor belts (e.g. on silos).

Brief description

The external vibrator is a construction machine for concrete processing which deals with the compaction
of liquid concrete. For this purpose, the external vibrator is firmly attached to a formwork and transfers
vibrations from there into the concrete.
Inside the external vibrator is an electric motor, which helps drive an eccentric weight. Different
centrifugal forces can be set by adjusting the balance of the eccentric weights or the number of eccentric
discs.
Concrete has to be compacted to eliminate the air inclusions in fresh concrete. This is how concrete gets
its solidity.
The eccentric discs must be symmetrically mounted to avoid damage to formworks.

Bodyguard
The Bodyguard® connects the mains supply line with the converter and monitors the operating currents
flowing in and out. The Bodyguard® helps protect the operator from electric shock in case of failure
(leakage currents).
The indicator light illuminates in red when the machine is closed correctly and the machine functions
correctly.
The indicator light doesn't illuminate when a leakage current occurred inside the machine.In this case,
the mains side power supply is cut off and the converter locked. The machine does not operate. The
power supply remains cut off until the error is remedied.
The Bodyguard® features a test button to check the function of the Bodyguards®.
The machine only works in connection with the Bodyguard®.Inverter
The inverter comprises a current rectifier and a d.c.-a.c. converter monitored by an electronic control.
The current rectifier converts the input voltage (AC single phase) to DC voltage.
The d.c.-a.c. converter converts the generated DC voltage to three phase current (AC three phase).
When the machine is switched on, the control electronics provides a soft start and thus prevents critical
starting currents.
