Vertical - L-Acoustics arcs wide Rigging Manual

No bridled suspension on the WIFOBUMP frame
Always use 1 load-bearing line per pick-up point.
Pullback implementation
By using rigging points at the rear of the installed coupling bars, an ARCS
vertical array can be implemented in pullback configuration. Refer to APPENDIX A PULLBACK
IMPLEMENTATION.
Final check before flying the system
Coupling bars: All lugs of locking tabs must be secured, as indicated in PROCEDURE A.
Shackles: All safety pins must be secured as indicated in PROCEDURE D.
Truss clamping
By installing a CLAMP250 instead of a shackle, an array can be attached to a truss.
Refer to PROCEDURE D.
 Place the first enclosure (WIDE, FOCUS or SB18m) on the floor.
 For an array with 2 SB18m, place and lock a second SB18m on top of the first one.
Refer to PROCEDURE A to lock the SB18MRIG bars.
 Remove the top coupling bars from their storage location.
 Place the WIFOBUMP frame on the top enclosure and lock the coupling bars.
With an SB18m on top, refer to SOUNDVISION for the frame position (front or rear).
Refer to PROCEDURE A to lock the coupling bars.
 Attach a shackle on the WIFOBUMP.
Refer to PROCEDURE D.
 Raise the array so you are comfortable lifting and attaching the next enclosure.
 Bring the next enclosure and remove the bars from their storage location.
 With the rigging bar in hand, lift the next enclosure and attach it under the array.
Refer to PROCEDURE A to lock the coupling bars.
 To add more enclosures, repeat the previous 3 steps until the array is completed.
