Rechecking, hoisting and secondary safety
Safety and system checks
Before hoisting the array to its operating position, recheck the
actual status of the assembly as follows:
Mechanical setup
▪ Check the attachment of the Mounting frame(s) and/or adapter
frame to the cabinets:
▪ Ensure all Locking pins are fully inserted nad properly locked.
▪ Check the attachment of all Front links on both sides of the
cabinets and all Locking pins are fully inserted nad properly
locked.
▪ Check the splay angles and the attachment of the Splay/Rear
links at the rear of the cabinets:
▪ Ensure all Locking pins are fully inserted nad properly locked.
Wiring
▪ If the amplifiers are already wired and powered on, use their
System check functions or channel mute switches and a test
signal to check the correct operation and routing of all channels
and cabinets.
▪ Alternatively, check the wiring using the Array verification
function in R1.
Hoisting
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 checks and system
checks have been made, the array can be hoisted up to its
operating position and firmly attached to the onsite construction.
The chain hoist motors must raise the array slowly and evenly so
that it does not swing or move from side to side during hoisting.
5.1 Secondary safety
Once the array is in its final operating position, the secondary
safety device must be applied.
WARNING!
Potential risk of personal injury and/or
damage to material!
▪ The secondary safety suspension must be independent of the
primary suspension points and capable of carrying the total
system weight.
▪ The additional safety device must be mounted in a way that, if
the primary suspension fails, the array is caught by the safety
device without any drop or swing.
The secondary safety device must be attached to the front of the
frames using one of the first five holes.
