2.4. Hoisting and securing the array (secondary
safety)
When all the mechanical adjustments, system checks and safety
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 cable 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.
When the array is in its final operating position the secondary
safety must be applied.
