GEO D RIGGING PROCEDURE Page 65/97
5.7.7 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 SUB
compression chain and no compression on the system.
• Disconnect the bottom GEO SUB from the second GEO D Bumper and remove the Bottom
Extension Bar EX3.
• 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 SUB’s sit flat on the dolly.
• Lift the dolly manually below the array and connect it to the bottom GEO SUB 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 2 GEO SUB’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 EX2, and remember to
replace all the axes back in their respective beams.
5.8 Fixed installations
For fixed installation where GEOD / GEO SUB clusters are permanently in position and do not need to
be removed, push-pins can be replaced with GEOD BNFIX kit.
Stacking or Rigging procedures are identical to the ones described above; however BNFIX nuts and
bolts installation will be facilitated if front grid is removed.
• remove the front grill (drawings below);
