Hoisting, aiming and securing the array
8.1 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 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.
8.2 Aiming the array
In connection with the Z5711 ArraySight sender unit (laser
inclinometer), the horizontal and vertical aiming of the array can
be sufficiently and easily adjusted.
CAUTION!
Laser beam
Potential risk of personal injury.
The high brightness laser of the d&b ArraySight sender unit
requires additional safety considerations.
1. Take precautions to prevent anyone from looking directly
into the laser beam.
2. Wear appropriate eye protection.
3. When making adjustments to the array with motor hoists,
watch the hoist -
not the meter unit!
4. Check the measurement only when you are satisfied that the
hoist has finished moving safely.
5. However, the chain hoist motors must raise slowly and
evenly.
