general infOrMatiOn
When determining which head to choose it is important
to access the application. Mainly what are the dimensions
of the application. Select the vibrator head based on its
radiating radius charactertics. Reference Table 5.
Select the vibrating head that covers the largest possible
area without excessive overkill. This will allow for more
efficient productivity. General rule of thumb is DO nOT
select a vibrator head which has a vibration radius of more
than twice the width of the form.
Example:
If the form width is 9 inches (229 mm) the selected vibrator
head radius should not exceed an 18 inch (457 mm) radius.
In this example the 2600HD vibrator head would be the
recommended choice. Reference Table 5 and Figure 2.
NOTICE
Vibrator head spacing distance ( D) is calculated by
multiplying the vibrating head radius (area of influence)
by 1.5.
