2.4 Hog Head
The Hog Head (blasting head) assembly is a
double blasting head design mounted on the end
of the Hog Arm. The blasting heads are supported
by a tubular head plate chassis with three or four
heavy duty castor wheels that support the blast-
ing heads at a preset height to prevent the spray
bars from contacting the pavement.
A wear brush clamped to each blasting head
shroud provides a partial seal between the blast-
ing head and pavement. The wear brush regulates
vacuum air ow into the shroud and reduces the
amount of debris and water exiting the blasting
head during waterblasting operations. The wear
brush is an important safety feature of the blast-
ing head system. It must be adjusted as it wears
and replaced as necessary.
