Examples of Mounting External Vibrators
Poor Mount = Poorly Finished Concrete
The vibrator is mounted directly to the form wall.
Without a channel iron, the force output
concentrated where the vibrator is attached,
causing the wall to flex and may cause stress
cracks. The vibration is not evenly distributed
resulting in a poor concrete finish.

Excellent Mount = Superior Finished Concrete
The vibrator is mounted on a channel iron, which
acts as the transducer of the energy. The vibration
is evenly distributed along the length of the channel
iron, which results in an excellent concrete finish.
Do not weld the channel iron to horizontal
stiffeners. Cut out the channel to fit over stiffeners.
