Slope compensation
The folding boom is aligned horizontally via the
slope compensation.
If the terrain is uneven, the centre of gravity
of the folding boom can be changed using the
hydraulic slope compensation (1). Changing
the centre of gravity allows the folding boom to
be positioned parallel to the ground on a slope.
The slope compensation must always be locked
before road travel.
Slope compensation is locked automatically as
soon as the folding boom is folded.
When unfolding the folding boom, the slope
compensation is unlocked automatically after
successful folding.
1
The slope compensation consists of two hydraulic
cylinders that are locked or unlocked via lock valves.
Uniform transverse distribution is only achieved
with the slope compensation unlocked.
NOTE
Before starting road travel make sure that the
folding boom is locked and rests securely in the
folding boom rest. In addition, the parallelogram
and the slope compensation must be locked.
Collision protection
The collision protection protects the folding
boom against damage caused by collision with
a solid obstacle. The joint mechanism enables
escaping a collision in travel direction and in
opposite direction.
Sample figure
After the escape movement the collision protec-
tion will swing back to the initial position.
NOTE
Collision protection only with fully extended
working width. With reduced working width pay
attention to any obstacles around the outside
of the machine!
