6 Three-Way Tip Breakaway

Each boom wing tip or end incorporates a
three-way tip breakaway hinge which allows
the wing tip to break-away:
• Forwards,
• Backwards and/or
• Upwards
- minimising possible damage to the
boom should an obstacle be hit.
It is important the breakaway hinge is properly
adjusted for operating (just tightening the
spring does not facilitate the breakaway
function).

Close the ball valve on each lift cylinder for safety.
To Set-Up the Three-Way Tip
Breakaway:
1 Follow the 'Before Making Boom
Adjustments' instruction.
2 Lower the boom to a good working height
fully opened (working position).
3 Close the ball valves on the two hydraulic
lift cylinders for safety purposes.
4 The lower pivot plates need to be in line
with each other (A).
5 If the rose end is removed for any reason,
anti-seize should be applied to the thread
before it is screwed into the boom tip.
The rose end should be screwed into the
breakaway tip so that it measures 53 mm
from the boom tip face plate to the centre
of the rose end (B) or until correct vertical
alignment is achieved.

6 The small hole in the sprocket must align
with the hole in the side of the pivot plate.
This is adjusted by tightening or loosening
the turnbuckle (C).
7 The spring tension must be adjusted so
there is a 1-2 mm gap between the coils.
This applies the ideal amount of resistance
when breaking away.
The spring tension can be adjusted by
tightening or loosening the eye bolt.
The small hole in the sprocket must align with the hole in
the side of the pivot plate.

To Adjust the Turnbuckle:
1 Use an assistant to pull the boom wing tip
back until the large hole in the sprocket
aligns with the hole in the pivot side plate,
then place a pin (such as a screwdriver)
through the holes.
2 Have the assistant return the wing tip only
enough to remove spring tension.
Do not let the wing tip fully return,
otherwise the chain may jump off its
sprocket and cause injury.
With the boom tip pulled back, place a pin through the
holes to hold the sprocket to adjust the turnbuckle.
