2.5 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 three heavy
duty castor wheels that support the blasting head
at a preset height to prevent the spray bar from
contacting the pavement.
A wear boot clamped to the blasting head shroud
provides a partial seal between the blasting head
and pavement. The wear boot regulates vacuum
air flow into the shroud and reduces the amount of
debris and water exiting the blasting head during
blasting operations. The wear boot is an important
safety feature of the blasting head system. It must
be installed properly and replaced as necessary.
Refer to the Wear Boot in this section and the
Routine Maintenance section of this manual for
additional information on the wear boot.
NOTICE:
ALWAYS MAKE SURE TO CHECK THE HOG HEAD FOR SMOOTH
AND PROPER OPERATION BEFORE EACH SHIFT. DO NOT USE
EqUIPMENT THAT HAS NOT BEEN CHECKED THOROUGHLY.
The flexible design of the tubular head plate allows
the operator to configure the blasting head in a
variety of configurations to accommodate differ -
ent water blasting operations. Special brackets
with jam bolts and nuts secure the spray heads
and other tubular head plate components in the
desired position.
The spray bar is rotated by a special hydraulic
powered “thru-shaft” motor. The center of the ro-
tating shaft is drilled to allow high pressure water
to pass through the shaft to the spray bar. Spray
bar rotation is controlled by the HEAD ROTATION
speed dial on the switch control panel.
The Hog Head design allows the operator to choose
several different length spray bars for specific
removal widths. The operator can choose spray
bar rotation speeds between 700 and 3000 RPM
using HEAD ROTATION speed dial.
The tubular head plate is equipped with three ad-
justable heavy duty castors wheels that support
the blasting head and prevent the spray bar and
shroud from touching the road surface. The castor
wheels are attached to heavy duty arms mounted

to the tubular head plate. The arms swivel to allow
the wheel location to be adjusted to avoid hazards
such as rumble strips and road reflectors or to ac -
commodate other operating situations. The arms
are secured in position by adjustable friction plates
with a bolt and jam nut locking system. The arms
are adjusted by loosening the jam nut and moving
