Opening/closing booms
|
Unfolding 1. Raise the boom so that the indicator on the lift ram comes above the top rail on the height mast. 2. Open the first boom section out, if a locking ram is fitted there will be a delay before the boom starts to move, the same applies when folding
3, Open boom out to full width
"second fold" (if applicable).
4. Lower boom to working height.
Folding 1. Make sure you are parked on level ground and are well clear of obstacles and overhead power cables.
2. Using the hydraulic tilt ram
ensure that the boom is level.
3. Raise the boom so that the mark
on the lift ram comes above the top rail on the height mast. 4. Fold outer sections in (if applicable). 5. Fold inner sections in until boom touches the vertical plates on the front boom rests. 6. Lower boom right down into boom rests ensuring all the pressure is off the hydraulics.
Hydraulic break-back
On some variants the second fold
rams may have a hydraulic break-back incorporated as a safety
precaution. This is used when the boom tips (and also the normal
break-back) have been removed from the 24m boom for spraying at 20m. |
