Ensures that the wing opens instead of the
breakaway mechanism. The breakaway bumper also
holds the wing straight when in the folded position
as long as they are properly ad usted first.
Brace Bar
The brace bar is fitted to the aluminium outer wing.
It is designed to hold the vertical weight of the
boom and is adjustable.
o le
The standard nozzle spacing on Goldacres booms
is 500 mm. Nozzles are mounted on brackets that
are adjustable for different nozzle types. Nozzles are
mounted so that they are protected from strikes
should the boom make contact with the ground,
obstructions or crop.
As information regarding no les is specific to those
being used in your application, no specific reference
is made to nozzle application rates or types in this
operator's manual. Goldacres suggest the use of a
current TeeJet or Lechler nozzle selection catalogue
for reference to nozzle sizes, outputs, spray patterns
and general spraying information. For more technical
information on the function of spray nozzles and
factors affecting their performance you can also use
the TeeJet 'User's guide to spray nozzles'.
The TeeJet & Lechler nozzle selection catalogues and
'User's guide to spray nozzles' are available from your
Goldacres dealer, or as a free download from:
TeeJet web site: www.teejet.com

TriTech booms feature the unique three dimensional
breakaway hinge which allows the tip to "break"
forward, backward and upward if an obstruction
is hit. The 3D breakaway hinge aims to eliminate
any further damage to the remainder of the boom
should an obstruction be hit.
It is important that the 3D breakaway hinge is
properly adjusted when in operation. Just tightening
the spring will not help with the function of the
breakaway. Instructions on how to properly adjust
the breakaway can be found later in this chapter.

Hydraulic yaw suspension is designed to control the
yaw movement of the boom centre section. Two
hydraulic cylinders with individual nitrogen filled
accumulators connected to each, centre and dampen
the yaw movement. The two hydraulic cylinders and
accumulators are charged with hydraulic pressure
and then closed off to create a separate circuit
which acts as the yaw suspension.
The overall yaw travel is limited by rubber bumpers
mounted to the Paralift rear. If the boom centre
section yaws excessively the centre section will
contact these and cushion the travel by collapsing
the block. If the block collapses totally the yaw travel
will be stopped. If the boom is continually yawed
excessively this block will wear out and require
replacement.

The boom tilt function allows the individual boom
sides to be raised independently when in the
working position. This serves to provide greater
variability of boom height control to compensate
for undulating ground conditions. Boom tilts are
operated from switches in the cabin.
api Fire api Flow
The RapidFlow system is complimentary to
Rapid ire and is fitted at the same time. The
RapidFire system provides rapid, individual nozzle
shut off that is controlled by air operated solenoids
at each nozzle. This system replaces the boom valves
and standard check valves that shut off the boom
sections and no les. This provides greater flexibility
in changing boom section widths and faster shut off
at the nozzle.
The RapidFire system reduces the amount of
plumbing on the sprayer and allows for the fitting
of a boom recirculation system. The ability to
have more boom sections also works perfectly in
conjunction with AccuBoom shut off systems.
In order to ensure that boom lines are charged and
ready to spray, a standard sprayer plumbing system
will require the boom lines to be purged with
chemical mix prior to spraying. RapidFlow allows an
agitated chemical mix to be run through the boom
lines prior to spraying - pre-charging them and
eliminating waste.
