d&b xA-Series - Manual (Page 15)

The xA-Series rigging system provides several options to suspend
xA-Series arrays depending on the various requirements on-site.
WARNING!
The array must be suspended using appropriate steel wires or
hoisting chains or using the d&b Z5147 Rota clamp (single
pickpoint operation). Any other type of suspension of the array is
not allowed.
The working load limits of the steel wires or chain hoists and their
suspension points must be high enough to carry the total system
weight.
Each of the suspension points must be able to carry the total system
weight.
3.1. Vertical arrays
Vertical xA-Series arrays may consist of 10AL (-D) or 10A (-D)
cabinets in combination with 18A or 27A subwoofers. This section
describes the suspension options for 10AL (-D) line arrays planned
using ArrayCalc.
3.1.1. Z5415 Flying bar adapter xA
The array is suspended using the Z5414 Flying bar xA together
with the Z5415 Flying bar adapter xA. Single or dual pickpoint
operation is possible.
On the upper edge of the flying bar adapter twelve 12.5 mm
[0.5"] holes are provided to accept:
– 1t Shackle (e.g. d&b E6507)
– d&b Z5147 Rota clamp
Þ single pickpoint operation to allow the attachment to
overhead bars or truss with a tube diameter of up to 51 mm
(2").
The adapter can be aligned in two directions (rearward [R] or
forward [F]) by simply turning the flying bar through 180°.
The corresponding hole positions for either single or dual pickpoint
operation are calculated using ArrayCalc.
Note: The calculated hole positions also apply when two
flying bar adapters are attached to the flying bar.
Single pickpoint operation
In single pickpoint operation, the position of the chosen hole
defines the overall vertical aiming of the entire array.
Within ArrayCalc the orientation of the adapter changes
according to the center of gravity of the array. If both orientations
are possible, the rearward orientation [R] is chosen. The direction
in which the holes are counted changes correspondingly.
