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
to the cabinets:
▪ Ensure all Locking pins are properly inserted and locked.
▪ Ensure all Fixing bolts are properly fitted and secured by a
locked Ring cotter.
▪ Check the attachment of all Front links on both sides of the
cabinets and ensure all Locking pins are properly inserted and
locked.
▪ Check the splay angles and the attachment of the Splay/Rear
links at the rear of the cabinets:
▪ Ensure all Locking pins are properly inserted and locked.
▪ Ensure all Fixing bolts are properly fitted and secured by a
locked Ring cotter.
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 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 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.
