Hydraulic Manifold
The Hydraulic manifold is mounted on the tree
near the uid reservoir. Electric solenoid valves
activated by switches in the control panels direct
hydraulic pressure to the various components
in the waterblasting hydraulic system. It is also
equipped with a regulator between the low and
high pressure side of the manifold that is used
to adjust the low pressure setting. The solenoid
valves are a cartridge type design that are easily
replaced in the event of a failure.
Hydraulic Motors and Actuators
The charge water pump and spray bar thru-shafts
are powered by hydraulic motors. Internal com-
ponents of the motors are lubricated and cooled
by the hydraulic uid that powers the motor. All
hydraulic motors have maximum pressure ratings
and RPM settings that should never be exceeded.
Most hydraulic motors are designed to rotate in
one direction. If a motor needs to be removed
for any reason, always make sure to mark the
hoses and ports so they will be installed in the
correct position. If the hoses are installed in the
wrong ports the motor will rotate opposite of the
designed rotation which will permanently damage
the motor.
Hydraulic Cylinders
Two types of hydraulic actuators are used in the
waterblasting hydraulic systems. Rotary, “Helac”
cylinders are used on the Hog Arm and conven-
tional ram type cylinders are used on debris tank
components.
Helac cylinders provide a broader range of move-
ment than conventional ram type cylinders. The
cylinders and hinged arm joints are integrated so
the joint bearings are lubricated by the hydraulic
uid that powers the cylinders, eliminating grease
