2.4. Ring cotters
In connection with the V-Series rigging system, ring cotters are used
for the following items to prevent the respective item from
slackening and/or loosening:
–
Fixing bolt of the SUB cabinet's Rear link.
– Fixing bolt of the frame's Splay link and cable pick.
– Fixing bolt of the 2 t shackles attached to the Load adapters
and safety points of the Flying frame.
– Fixing bolt of the Z5147 Rota clamp.
Function of the ring cotter
By default, the ring cotters are "locked" to prevent them from
loosening.
For modification reasons such as altering the position of the frame's
Splay link or exchanging a shackle, it may be necessary to
temporarily remove the cotter and reattach it afterwards.
Note: Please also refer to Þ Chapter 7. " Care and
maintenance / Disposal", Þ section 7.2. " Visual and
functional inspection", Þ "Ring cotters" on page 43.
For this purpose proceed as follows:
1. Unlock
Unlock the ring cotter by pushing up the front wire loop over
the straight wire shaft.
2. Release and remove
Push down the rear wire loop until the ring cotter snaps over
the edge of the bolt and remove the ring cotter.
3. Refit and lock
Refit the ring cotter by pushing the straight wire shaft through
the hole and pressing the front wire loop underneath the
straight wire shaft.
