MANUAL FOLDING BOOMS
General information
The boom fitted as standard is part of the
Goldacres range of "folding booms" which
are available in sizes from 3 metres to 10
metres� These booms are constructed from
RHS and aluminium for strength and light
weight, the wings fold in for transport, and
jet bodies are mounted on stainless steel
brackets behind the boom for protection�
All booms, regardless of their design and
operating width, present certain safety
hazards in their operation� Please ensure
that you have read all safety precautions as
included in this manual and take particular
note of those re-listed below�
WARNINGS
• Never stand within the radius of boom
wings�
• Keep clear of overhead obstructions�
• CRUSH HAZARD - Keep hands clear of
moving parts when carrying out boom
fold and unfold sequences�
CAUTIONS
• Always ensure that there is adequate
room for the boom to open�
• Always ensure that the boom is
adequately supported when transporting�
Boom height
The standard nozzle spacing on Goldacres
booms is 500mm� For this spacing, the
optimum height the boom should be from
the object to be sprayed (with a 110° fan
angle nozzle) is 500mm�
There will be adequate spray coverage if
the nozzles are higher than this but this
increases the potential for drift� The spray
pattern is affected by many factors not
limited to, but including, gravity, pressure,
chemical composition and droplet size
so the pattern does not extend to the full
theoretical coverage� Refer to the TeeJet
nozzle selection catalogue for further
information on spray application and nozzle
technology
Boom height adjustment
Adjust the height of the boom by loosening
the nuts on the U-bolts clamping the boom
to the frame�
Raise or lower the boom to the desired
height and then re-tighten the nuts on the
U-bolts�
