10 Disassembling Flown Arrays
10.1 Disassembling a compressed array
Heads up: Always keep the area below the system clear of people when raising or
lowering it.
1
Lower the array to a convenient working height.
Heads up: Make sure no one is in the danger zone designated above when you release
the tensioning strap.
2
Release the tensioning strap step by step until the array is perpendicular to the ground and the rear
load is fully distributed across the link pins. Remove the CRF-PB together with the tensioning end of
the tensioning strap.
3
Set the angle pins of all M/H units within your reach at this working height to 0°. This connects the
M/H units to each other at the 0° angle required for fi xed mode.
4
Remove the C-WB's cover and place it below the array. Lower the array until the lowest M/H unit
rests on the C-WB. Attach this M/H unit to the C-WB using the quick-release pins.
Recommendation: You can attach the C-WB to the suspended M/H unit if the fl oor is uneven.
Make sure the C-WB is on secure footing before you move on to the next step.
5
Disconnect the top M/H unit of the stack that you want to roll away from the array.
6
Roll the C-WB out of the danger zone and connect the top M/H unit to the C-WB's cover. The loaded
C-WB is now ready to go.
7
Repeat steps
3
through
6
until you have disassembled the entire array.
10.2 Disassembling a fi xed array
Heads up: Always keep the area below the system clear of people when raising or
lowering it.
Note: These instructions for disassembling a fi xed array assume that all M/H units are
disconnected one at a time. Easy, safe disassembly requires at least two people.
1
Lower the array to a convenient working height
2
Starting with the lowest M/H unit, remove the fi x pin from the angle plate and the two pins from the
front attachment points. This disconnects the M/H unit from the array so you can set it on a suitable
means of transport such as a C-WB.
Note: This is a buddy-system job – you need two people to do it.
3
Repeat step
2
until you have removed all M/H units. Keep lowering the array to a convenient working
height as you progress.
Recommendation: You can also take down several mid/high units in one go with the C-WB
wheel board. See section 10.1 for more on this.
