Hoisting, aiming and securing the array
12.1 Hoisting the array
WARNING!
Potential risk of personal injury and/or
damage to material!
Always ensure that each of the hoists is able to carry the total
weight of the array.
When hoisting the array, unpredictable dynamic forces as well as
swinging of the array must be taken into account. This may lead to
personal injury and/or damage to the rigging components and
loudspeaker cabinets.
Ensure that there is nobody directly underneath or in the vicinity of
the load who is not involved in the setup.
When all the mechanical adjustments, safety and system checks
have been made, the array can be hoisted up to its operating
position.
When hoisting the array, ensure that the loudspeaker cables do
not get caught anywhere. The cables can be strapped together
with the motor cables to form a loom while the system is hoisted.
The chain hoist motors must raise the system slowly and evenly so
that it does not swing or move from side to side during hoisting.
12.2 Aiming the array
12.2.1 Horizontal aiming
In connection with the Z5707 SL Aiming plate the horizontal
aiming of the array can be sufficiently and easily adjusted.
Note: To prevent the array from heavy movements, raise one
hoist while lowering the other.
However, the chain hoist motors must be operated slowly and
evenly.
With a chain hoist distance of minimum 0.6 m (2 ft), preferably
approx 1 m (3 ft), the SL Aiming plate provides a horizontal angle
range of
±
15° (first and last pick holes of the load beam used).
