Booms
General information
Folding booms sized between 4 and 6 metres
can be fitted to this product as an option.
These booms are constructed from steel
and aluminium for the best combination of
strength and light weight. The wings can fold
in for transport and storage, 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.
• 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 500 mm. For this spacing, the
optimum height the boom should be from the
object to be sprayed (with a 110° fan angle
nozzle) is 500 mm.
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.
