2.9 Auxiliary Blasting Tool Connection
General
When an optional Ground Hog is connected to
the auxiliary connections, the electrical system
senses that the tool is connected. The levers on
the tool then control Ultra-High Pressure water
to the blast head and hydraulic fluid flow to the
spray bar thru-shaft motor. Ultra-high pressure
water, hydraulic power and vacuum are provided
by the truck waterblasting system.
Control Harness Connection
An electrical harness that runs from the outlet plug
on the front of the truck to a plug on the ground
hog connects the control switch levers on the tool
with the waterblasting electronic control system
on the truck. Once the harness is connected, the
operator controls the high pressure water and
hydraulic systems on the tool blast head with the
control switch levers on the tool.
Hydraulic Connection
Hydraulic hoses with quick disconnect fittings are
connected from the tool to the truck hydraulic sys-
tem at the auxiliary tool connection. The hydraulic
control lever on the tool provides the operator with
full control of the hydraulically activated thru-shaft
motor that rotates the spray head.
Vacuum Connection
Hand operated tools like the Ground Hog (Walk
behind) are equipped with blast heads that are
designed to be attached directly to the vacuum
system. The hose quick disconnect fittings provide
vacuum from the truck vacuum system to the
blast head. Once the hose is connected, vacuum
is supplied to the tool whenever the waterblasting
system is activated.
Make sure to protect the hoses from damage and
abrasion from dragging on the pavement. This
is particularly important when working a long
distance from the truck. In some situations anti-
chaffing protection may need to be added to the
hoses to protect them in contact areas.
