4.1.2. Derigging
The same safety instructions as for the set up apply and the following
order is recommended:
1. Lower the array and stop before the lowest cabinet hits the ground.
2. Attach the wheel boards beginning with the lowest cabinet.
3. Continue to lower the array and carefully tip the lowest wheel
board onto the ground.
4. Stop lowering the array at this point.
RIGHT!
WARNING!
WRONG!
Continuing lowering the array at this point could lead to
the potential risk to tip over the array towards the front
before - depending on the type of ground (arena
floor/free field) - the array could roll towards the back in
a sudden.
This will cause a potentially dangerous situation which
may lead to personal injury.
In particular make sure that during lowering the array
no person is underneath or within the vicinity of the
array.
Before continuing lowering the array with one person to
each side of the array give support to the side handles of
the lowest cabinet. While lowering the array give
direction towards the back of the array to ensure the
array will be lowered straight down and safely rolled to
the back. It is advisable all persons involved in lowering
the array are close by to give instructions if necessary.
5. Continue to lower the array and with one person on each side of
the cabinets attach the remaining wheel boards.
6. When all wheel boards are attached the array can be fully dropped
onto the ground.
7. Remove the cabling.
8. Remove the lower Locking pins which were used to secure the Splay
links.
9. Lift the Flying frame until the full curving of the array is reached and
the hooks of the Splay links are released.
10. Flip back the Splay links to their park position and fix them with the
Locking pin.
11. Lower the Flying frame again until all cabinets stand on their wheel
boards.
12. Remove the Flying frame and store all items (Splay link / Load
adapter) back into their park positions.
13. Separate the cabinets and store back the Front links into their park
position.
