5. Aiming and securing of the array
5.1.
Horizontal aiming and securing of the array
[R2]
[R4]
[CR]
Fig. 31: Rigging sockets for horizontal
aiming and securing against rotation and
swing
After the array has been lifted to its operating height the horizontal aiming
has to be set and the array should be secured against rotation and swing.
It is recommended to use the following rigging sockets on the lowest
cabinet:
Sockets
[R2]
or
[CR]
with Z5048 Flying pins 10 mm.
M10 threaded inserts
[R4]
with Q9032 M10 Safety eyebolts.
WARNING!
If the system is used in an open air environment the
influence of wind has to be taken into account. The
protection against rotation and swing has to withstand
higher forces. Do not secure the array with the centre
socket [CR] (Fig. 31) at the back of the cabinet. This socket is
limited to a load of 50 kg (110 lb).
Read the following section 6. Wind loads.
5.2.
Modifying the vertical aiming of the array
If an application requires the array to have a vertical angle which is not
possible by a single suspension within the hole grid of the Q Flying frame
additional wires or hoists may be needed to achieve this.
With arrays of up to three cabinets the standard rigging sockets on the
cabinets may be used (Fig. 31).
Fig. 32: Applying a
second Q Flying frame
to increase the vertical
angle of the array
WARNING!
To angle an array of more than three Q-Series cabinets an
additional Z5159 Q Flying frame has to be attached to the
lowest cabinet of the column. All additional wires or hoists
have to be connected to the Q Flying frame and not to the
cabinets rigging sockets (Fig. 31).
Always pull the additional wires or hoists backwards and
upwards (Fig. 32).
Using additional wires or hoists will change the load
conditions within the array and its rigging components. The
load calculation of ArrayCalc will not apply any more.
Therefore increasing the vertical angle of an array is only
possible with columns up to a total system weight of 240 kg
(527 lb).
