5.5.7 De-rigging and loading out
Taking the system down is just a case of doing the reverse procedure to flying the array. However,
there are some important factors to consider.
•
Lower the array running the two motor hoists simultaneously until the bottom cabinet is just off
the floor, main bumper being horizontal.
•
Rotate the chain hoist lever counter-clockwise until there is no tension on the GEO D
compression chain and no compression on the system.
•
Disconnect the bottom GEO D from the bottom bumper and remove the bottom bumper from the
array.
Link cables must be disconnected and stowed away in the recesses in the rear of each
cabinet.
•
NB : As the system is lowered it is good practise to disconnect as many loudspeaker cables as
can be reached without climbing the array. This ensures that a cable should not be accidentally
forgotten when the system is separated. Damage to the connector will occur should this mistake
be made.
•
Angle adjustment push-pins should be removed from the angle setting and inserted in the “FIX”
hole so that Geo D’s sit flat on the dolly.
•
Lift the dolly manually below the array and connect it to the bottom GEO D with 4 push-pins.
Carefully lower the array so that the dolly being on the ground is not being submitted to
the entire cluster weight.
•
Disconnect the first block of 3 GEO D’s at the connection between 3
rd
and 4
th
bottom cabinets.
•
Carefully lift the array using both motor hoists until the array is clear. Ensure the array is vertical
at all times.
•
Repeat the procedure for all cabinets.
•
Remove the GEO D compression chain from the GEO D extension bar, slide the extension bar
into the bumper and remember to replace all the axes back in their respective beams.
