Stripe Hog Systems
The hydraulic actuators used to lift the debris cage
are equipped with special counterbalance valves
that prevent the cage from dropping suddenly if
a hose ruptures or a fitting fails.
All hydraulic circuits and actuators require special
procedures for bleeding air from the system after
servicing components or replacing hoses. Contact
Hog Technologies if you need assistance in bleed-
ing the air from the hydraulic system.
Hydraulic Hoses
The hydraulic system operates at pressures of
up to 3,000 psi (207 BAR). Therefore, it is criti-
cal that the operator and maintenance personnel
inspect the hydraulic hoses, fittings and other
components frequently. A visual inspection of the
entire hydraulic system should be conducted each
day before operating the unit. Any hose or com-
ponent that is questionable or shows any sign of
deterioration, wear or leakage should be replaced
immediately and before operating the unit. A more
thorough inspection of the pump and components
should be conducted at each routine service inter-
val. Remember that the hydraulic system can be
severely damaged if it runs low on fluid.
Protect the hoses from contact with sharp objects
or kinks. Never operate the hydraulic system with
a damaged hose or a hose that is questionable.
2.12 Hydrostatic Drive Wheel
The hydrostatic drive wheel moves the truck in
work mode. It is powered by the hydraulic system
and controlled by the TRUCK SPEED dial during
blasting operations.
The wheel assembly is attached to the trailer
hitch on the truck chassis. A hydraulic actuator
controlled by the WHEEL UP/DOWN switch raises
and lowers the wheel. The actuator also applies
pre-programmed down force on the wheel for
maximum traction. Rubber isolators in the wheel
assembly kingpin automatically center the wheel
after a turn and provide proper tracking during
operation. The wheel should be lowered just be -
fore blasting operations begin and raised when
blasting is stopped.
The wheel is designed to push the truck forward.
It is not designed to pull the truck backwards. The
drive wheel can be reversed for minor corrections,
however, the maximum reverse distance is 3 to
