2.4 Hog Head
The Hog Head (blasting head) assembly is a single
blasting head design mounted on the end of the
Hog Arm. The blasting head is supported by a
tubular head plate chassis with four heavy duty
castor wheels that support the blasting head at a
preset height to prevent the spray bar and shroud
from contacting the pavement.
A wear brush clamped to the shroud provides a
partial seal between the blasting head assembly
and pavement. The wear brush regulates vacuum
air flow into the shroud and reduces the amount of
debris and water exiting the blasting head during
blasting operations.
The wear brush is a important safety feature of
the Hog Head and must be adjusted as it wears
and replaced as necessary. It should always be
adjusted so the brushes are making light contact
with the pavement.
